REMARKS:
152100Z POSITION NEAR 10.2S 132.1E.
TROPICAL CYCLONE 15S (FIFTEEN), LOCATED APPROXIMATELY 166 NM
NORTH-NORTHEAST OF DARWIN, AUSTRALIA, HAS TRACKED SOUTH-
SOUTHEASTWARD AT 04 KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED 
SATELLITE IMAGERY SHOWS PERSISTENT DEEP CONVECTION OVER THE WESTERN 
PORTION OF A CONSOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC). THE 
INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE 
INFRARED LOOP AND A 151852Z 37GHZ SSMI/S MICROWAVE IMAGE SHOWING 
DEEP CONVECTION WRAPPING INTO A LLCC. THE INITIAL INTENISTY IF 35 
KNOT IS HEDGED SLIGHTLY ABOVE AGENCY DVORAK ESTIMATES OF T2.0 (30 
KNOTS) FROM PGTW AND KNES BASED ON SURFACE OBSERVATIONS NEAR THE 
SYSTEM OF 32 KNOTS. UPPER LEVEL ANALYSIS REVEALS A POINT SOURCE 
ALOFT OVER THE SYSTEM WITH WEAK EQUATORWARD OUTFLOW. ENVIRONMENTAL 
ANALYSIS DEPICTS THAT THEY SYSTEM IS IN AN AREA OF STRONG (20-25 
KNOT) VERTICAL WIND SHEAR AND IS TRACKING THROUGH AN AREA OF WARM 
(29-30 CELSIUS) SEA SURFACE TEMPERATURES. TC 15S IS CURRENTLY 
RECURVING TO THE SOUTHWEST UNDER THE INFLUENCE OF AN EXTENSION OF 
THE STEERING SUBTROPICAL RIDGE LOCATED TO THE SOUTHEAST. TC 11S IS 
EXPECTED TO STEADILY INTENSIFY TO 50 KNOTS BY TAU 24. AFTER TAU 24, 
LAND INTERACTION WILL BRIEFLY WEAKEN THE SYSTEM AS IT TRACKS BETWEEN 
MAINLAND AUSTRALIA AND THE TIWI ISLANDS. THE SYSTEM IS FORECAST TO 
TRACK ALONG THE NORTHWEST COAST OF AUSTRALIA THROUGH TAU 72 AT WHICH 
TIME THE TRACK DIRECTION BECOMES MORE WESTWARD AS TC 15S MOVES OUT 
INTO THE SOUTHERN INDIAN OCEAN. THE SYSTEM WILL STEADILY INTENSIFY 
AFTER TAU 36 AS FAVORABLE CONDITIONS PERSIST, REACHING 80 KNOTS BY 
TAU 120. AVAILABLE DYNAMIC MODEAL GUIDANCE IS GOOD AGREEMENT WITH 
THE TRACK DIRECTION HOWEVER, INDIVIDUAL CONSENSUS MEMBERS VARY 
SIGNIFICANTLY ON HOW FAR INLAND THE SYSTEM WILL TRACK. THESE 
VARIATIONS IN TRACK LOCATIONS CAUSE EXTENSIVE VARIATIONS IN BOTH 
ALONG TRACK SPEED AND INTENSITY GUIDANCE. DUE TO THE UNCERTAINTY IN 
THE MODEL GUIDANCE, THERE IS OVERALL LOW CONFIDENCE IN THE JTWC 
FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 151800Z IS 10 
FEET. NEXT WARNINGS AT 160300Z, 160900Z, 161500Z AND 162100Z. THIS 
CANCELS AND SUPERSEDES REF A (WTXS21 PGTW 150500). REFER TO TROPICAL 
CYCLONE 14S (ELIAKIM) WARNINGS (WTXS31 PGTW) FOR SIX-HOURLY

REMARKS:
160300Z POSITION NEAR 10.8S 132.5E.
TROPICAL CYCLONE 15S (FIFTEEN), LOCATED APPROXIMATELY 152 NM
NORTHEAST OF DARWIN, AUSTRALIA, HAS TRACKED SOUTH-SOUTHEASTWARD
AT 06 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTI-SPECTRAL 
SATELLITE IMAGERY SHOWS DEEP CONVECTION CENTRALLY LOCATED OVER AND 
OCCLUDING A CONSOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC). THE 
INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE 
MULTISPECTRAL LOOP AND THE ANIMATED RADAR LOOP FROM THE AUSTRALIAN 
BUREAU OF METEOROLOGY. THE INITIAL INTENSITY OF 40 KNOTS IS BETWEEN 
MULTI-AGENCY AGENCY DVORAK CURRENT INTENSITY ESTIMATES RANGING FROM 
T2.5 TO T3.0 (35-45 KNOTS) FROM PGTW AND KNES RESPECTIVELY. UPPER 
LEVEL ANALYSIS REVEALS THE SYSTEM HAS GOOD EQUATORWARD OUTFLOW AND 
NO ORGANIZED POLEWARD OUTFLOW. ENVIRONMENTAL ANALYSIS DEPICTS THAT 
THEY SYSTEM IS IN AN AREA OF LOW TO MODERATE (15-20 KNOT) VERTICAL 
WIND SHEAR AND IS TRACKING THROUGH AN AREA OF WARM (29-30 CELSIUS) 
SEA SURFACE TEMPERATURES. TC 15S IS CURRENTLY TRACKING SOUTH-
SOUTHEAST AS IT IS RECURVING TO THE SOUTHWEST UNDER THE INFLUENCE OF 
AN EXTENSION OF THE STEERING SUBTROPICAL RIDGE LOCATED TO THE 
SOUTHEAST. TC 15S IS EXPECTED TO STEADILY INTENSIFY AS IT APPROACHES 
NORTHERN AUSTRALIA, REACHING A PEAK OF 50 KNOTS BY TAU 24. AFTER TAU 
24, EXTENSIVE LAND INTERACTION WILL CAUSE A BRIEF WEAKENING TREND AS 
THE SYSTEM TRACKS BETWEEN MAINLAND AUSTRALIA AND THE TIWI ISLANDS. 
THE SYSTEM IS FORECAST TO TRACK SOUTHWEST ALONG THE NORTHWESTERN 
COAST OF AUSTRALIA THROUGH TAU 72. AFTER TAU 72, THE TRACK DIRECTION 
SHIFTS MORE WESTERLY ALONG AN EXTENSION OF A STR ANCHORED OVER 
CENTRAL AUSTRALIA. AS THE SYSTEM MOVES OUT OVER THE SOUTHERN INDIAN 
OCEAN IT WILL STEADILY INTENSIFY UNDER FAVORABLE CONDITIONS, 
REACHING 85 KNOTS BY TAU 120. AVAILABLE DYNAMIC MODEL GUIDANCE IS IN 
RELATIVELY GOOD AGREEMENT WITH THE TRACK DIRECTION. THE INDIVIDUAL 
CONSENSUS MEMBERS VARY SIGNIFICANTLY ON HOW FAR INLAND THE SYSTEM 
WILL TRACK WHICH IS CAUSING LARGE VARIATIONS IN BOTH THE ALONG TRACK

REMARKS:
160900Z POSITION NEAR 11.3S 131.8E.
TROPICAL CYCLONE (TC) 15S (MARCUS), LOCATED APPROXIMATELY 102 NM
NORTHEAST OF DARWIN, AUSTRALIA, HAS TRACKED SOUTH-SOUTHWESTWARD AT 06
KNOTS OVER THE PAST SIX HOURS. ANIMATED MSI SHOWS THE SYSTEM HAS
MOSTLY MAINTAINED CONVECTIVE STRUCTURE EVEN AS IT TRACKED BETWEEN THE
ISLANDS NORTH OF DARWIN. THE INITIAL POSITION IS BASED ON A WELL-
DEFINED CIRCULATION IN THE COMPOSITE RADAR LOOP FROM DARWIN WITH HIGH
CONFIDENCE. THE INITIAL INTENSITY IS AVERAGED FROM AGENCY DVORAK
ESTIMATES FROM PGTW, KNES, AND ADRM RANGING FROM T2.5 TO T3.0 (35 TO
45 KNOTS). TC 15S IS EXPECTED TO CONTINUE ON A SSW-WARD TRACK ALONG
THE NORTHERN PERIPHERY OF THE STR THAT IS ANCHORED WEST-EAST OVER
CENTRAL AUSTRALIA AND DRAG ALONG THE NORTHERN AUSTRALIAN COASTLINE.
BY TAU 72, JUST NORTH OF BROOME, IT WILL TRACK MORE WESTWARD INTO THE
SOUTH INDIAN OCEAN (SIO). DUE TO LAND INTERACTION, MARCUS WILL
STRUGGLE OVER THE NEXT 48 HOURS BUT AFTER IT EXITS INTO THE SIO, A
RAPID INTENSIFICATION PHASE WILL COMMENCE, AIDED BY ANTICIPATED
STRONG OUTFLOW, LOW VWS, AND WARM SSTS IN THE AREA. BY TAU 120, TC
15S IS FORECAST TO REACH 100 KNOTS. THE AVAILABLE NUMERIC GUIDANCE IS
IN TIGHT AGREEMENT; HOWEVER, LAND INTERACTION DURING THE NEAR TERM
MAY AFFECT ITS STORM MOTION, LENDING LOW CONFIDENCE IN THE INITIAL
PORTION OF THE JTWC FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
160600Z IS 12 FEET. NEXT WARNINGS AT 161500Z, 162100Z, 170300Z AND
170900Z. REFER TO TROPICAL CYCLONE 14S (ELIAKIM) WARNINGS (WTXS31

REMARKS:
162100Z POSITION NEAR 11.9S 131.3E.
TROPICAL CYCLONE 15S (MARCUS), LOCATED APPROXIMATELY 63 NM
NORTHEAST OF DARWIN, AUSTRALIA, HAS TRACKED SOUTH-SOUTHWESTWARD
AT 06 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY DEPICTS FLARING CENTRAL CONVECTION ORGANIZING 
AROUND THE LOW LEVEL CIRCULATION CENTER. THERE IS HIGH CONFIDENCE IN 
THE INITIAL POSITION WHICH IS BASED ON SATELLITE FIXES AND ANIMATED 
RADAR IMAGERY FROM DARWIN SHOWING MODERATE TO HEAVY RAIN BANDING 
WRAPPING INTO A DEFINED CIRCULAR CENTER JUST OFFSHORE AND SKIRTING 
THE COASTLINE. A 161839Z SSMIS IMAGE SHOWS DEEP CONVECTIVE BANDING 
ON THE NORTHERN PERIPHERY WITH LIMITED CONVECTION OVER THE SOUTHERN 
PORTION SITUATED OVER LAND. THE INITIAL INTENSITY OF 40 KNOTS IS 
BASED ON MULTI-AGENCY DVORAK ESTIMATES RANGING FROM T2.5 TO T3.0 (35 
TO 45 KNOTS). UPPER-LEVEL ANALYSIS SHOWS EASTERLY WINDS ALOFT 
CREATING A LOW TO MODERATE SHEAR ENVIRONMENT WITH NOTABLE 
DIFFLUENCE. SSTS ARE EXTREMELY WARM NEAR THE COAST LINE AROUND 31 
CELSIUS AND WILL REMAIN AT OR ABOVE 30 CELSIUS FOR THE REMAINDER OF 
THE FORECAST. TC 15S IS TRACKING SOUTHWESTWARD ALONG THE NORTHERN 
PERIPHERY OF A SUBTROPICAL RIDGE BUILDING OVER THE AUSTRALIAN 
CONTINENT WHICH WILL BECOME EAST-WEST ORIENTED AND SHIFT THE SYSTEM 
TO A GENERALLY WESTWARD TRACK. INITIALLY TC 15S WILL TRACK ALONG THE 
COASTLINE FOR THE FIRST 48 HOURS. THIS WILL MITIGATE THE 
INTENSIFICATION TREND DUE TO FRICTIONAL EFFECTS AND THE PRESENCE OF 
LOW TO MODERATE WIND SHEAR. BEYOND TAU 48 TC 15S WILL TRACK OVER 
OPEN WATER, AND WITH IMPROVING ENVIRONMENTAL CONDITIONS WILL 
INTENSIFY QUICKLY REACHING A PEAK INTENSITY OF 120 KNOTS BY TAU 
120.  DYNAMIC MODEL GUIDANCE SHOWS VERY GOOD AGREEMENT WITH CLOSE

REMARKS:
170300Z POSITION NEAR 12.6S 130.8E.
TROPICAL CYCLONE 15S (MARCUS), LOCATED APPROXIMATELY 13 NM EAST-
NORTHEAST OF DARWIN, AUSTRALIA, HAS TRACKED SOUTHWESTWARD AT 09
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY DEPICTS A TIGHTLY WOUND SYSTEM WITH PERSISTENT CENTRAL 
CONVECTION OBSCURING THE LOW LEVEL CIRCULATION CENTER. THERE IS HIGH 
CONFIDENCE IN THE INITIAL POSITION WHICH IS BASED ON SATELLITE FIXES 
AND ANIMATED RADAR IMAGERY FROM DARWIN SHOWING MODERATE TO HEAVY 
RAIN BANDING WRAPPING INTO A DEFINED CIRCULAR CENTER NOW OVERLAND. A 
162046Z 89GHZ GMI IMAGE SHOWS A MICROWAVE EYE FORMING IN THE UPPER 
LEVELS WITH A STRONG BAND OF CONVECTION ON THE NORTHERN PERIPHERY. 
THE EYE FEATURE IS NOT OBSERVABLE IN THE CORRESPONDING 37GHZ BAND OR 
IN RADAR IMAGERY. THE INITIAL INTENSITY OF 45 KNOTS IS BASED ON THE 
LOWER END OF PREVIOUS DVORAK ESTIMATES RANGING FROM T3.0 TO T3.5 (45 
TO 55 KNOTS) AND SUPPORTED BY LOCAL SURFACE OBSERVATIONS. UPPER-
LEVEL ANALYSIS SHOWS EASTERLY WINDS ALOFT CREATING A LOW TO MODERATE 
SHEAR ENVIRONMENT WITH NOTABLE DIFFLUENCE. SSTS ARE EXTREMELY WARM 
NEAR THE COAST LINE AROUND 31 CELSIUS AND WILL REMAIN AT OR ABOVE 30 
CELSIUS FOR THE REMAINDER OF THE FORECAST. TC 15S IS TRACKING 
SOUTHWESTWARD ALONG THE NORTHERN PERIPHERY OF A SUBTROPICAL RIDGE 
BUILDING OVER THE AUSTRALIAN CONTINENT WHICH WILL BECOME EAST-WEST 
ORIENTED AND SHIFT THE SYSTEM TO A GENERALLY WESTWARD TRACK. 
INITIALLY TC 15S WILL TRACK ALONG THE COASTLINE FOR THE FIRST 48 
HOURS. THIS WILL MITIGATE THE INTENSIFICATION TREND DUE TO 
FRICTIONAL EFFECTS AND THE PRESENCE OF LOW TO MODERATE WIND SHEAR. 
BEYOND TAU 48 TC 15S WILL TRACK OVER OPEN WATER, AND WITH IMPROVING 
ENVIRONMENTAL CONDITIONS WILL INTENSIFY QUICKLY REACHING A PEAK 
INTENSITY OF 125 KNOTS BY TAU 120. DYNAMIC MODEL GUIDANCE SHOWS VERY 
GOOD AGREEMENT WITH CLOSE GROUPING OF POSSIBLE SOLUTIONS. HOWEVER 
SLIGHT DIFFERENCES EXIST OVER THE FIRST 48 HOURS WHILE TRACKING SO 
CLOSE TO THE SHORELINE. DESPITE THESE SUBTLE DIFFERENCES IN THE 
SHORT TERM, THERE IS OVERALL HIGH CONFIDENCE IN THE JTWC FORECAST 
TRACK. NEXT WARNINGS AT 170900Z, 171500Z, 172100Z AND 180300Z.

REMARKS:
172100Z POSITION NEAR 14.0S 128.2E.
TROPICAL CYCLONE 15S (MARCUS), LOCATED APPROXIMATELY 158 NM WEST-
SOUTHWEST OF DARWIN, AUSTRALIA, HAS TRACKED WEST-SOUTHWESTWARD AT
08 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY DEPICTS PERSISTENT DEEP CONVECTION CENTRALLY 
LOCATED OVER AND OBSCURING THE LOW LEVEL CIRCULATION CENTER (LLCC). 
THE INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE 
ANIMATED INFRARED LOOP AND ANIMATED RADAR IMAGERY. THE INITIAL 
INTENSITY OF 50 KNOTS IS BETWEEN RECENT AGENCY DVORAK CURRENT 
INTENSITY ESTIMATES RANGING FROM T3.0 TO T3.5 (45-55 KNOTS) FROM 
APRF AND PGTW RESPECTIVELY. UPPER-LEVEL ANALYSIS INDICATES THE 
SYSTEM HAS GOOD POLEWARD AND EQUATORWARD OUTFLOW CHANNELS. 
ENVIRONMENTAL ANALYSIS SHOWS THE SYSTEM IS IN AN AREA OF MODERATE 
(15-20 KNOT) VERTICAL WIND SHEAR (VWS) AND IS TRACKING THROUGH WARM 
(30-31 CELSIUS) SEA SURFACE TEMPERATURES AS IT BRIEFLY TRACKS 
THROUGH THE JOSEPH BONAPARTE GULF. TC 15S IS CURRENTLY TRACKING 
SOUTHWESTWARD ALONG THE NORTHERN PERIPHERY OF A SUBTROPICAL RIDGE 
ANCHORED OVER THE CENTRAL AUSTRALIAN CONTINENT. THE TRACK IS 
FORECAST TO SHIFT, BECOMING MORE WESTWARD AS THE RIDGE BUILDS. AFTER 
TAU 72, 15S WILL TURN TOWARDS THE SOUTH ROUNDS THE WESTERN EXTENT OF 
THE RIDGE. IN THE NEAR TERM, THE SYSTEM WILL SKIRT THE NORTHWESTERN 
AUSTRALIAN COASTLINE AND REMAIN UNDER THE INFLUENCE OF MODERATE VWS, 
LIMITING INTENSIFICATION UNTIL AFTER TAU 36 WHEN THE CYCLONE IS OVER 
WATER AND THE ENVIRONMENT BECOMES MORE FAVORABLE. TC MARCUS IS 
FORECAST TO REACH A PEAK INTENSITY OF 120 KNOTS BY TAU 96.
AVAILABLE DYNAMIC MODEL GUIDANCE IS IN TIGHT AGREEMENT THROUGH TAU 
72 WHEN THE CONSENSUS MEMBERS BEGIN TO SPREAD. THE MODELS GUIDANCE 
LENDS HIGH CONFIDENCE IN THE JTWC FORECAST TRACK THROUGH TAU 72 WITH 
CONFIDENCE DECREASING AS THE UNCERTAINTY IN THE MODELS INCREASES. 
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 171800Z IS 15 FEET. NEXT
WARNINGS AT 180300Z, 180900Z, 181500Z AND 182100Z. REFER TO TROPICAL

REMARKS:
180300Z POSITION NEAR 14.3S 127.3E.
TROPICAL CYCLONE 15S (MARCUS), LOCATED APPROXIMATELY 208 NM WEST-
SOUTHWEST OF DARWIN, AUSTRALIA, HAS TRACKED WEST-SOUTHWESTWARD AT
08 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED MULTI-SPECTRAL 
SATELLITE IMAGERY DEPICTS AN EXPANDING MASS OF PERSISTENT DEEP 
CONVECTION CENTRALLY LOCATED OVER AND OBSCURING THE LOW LEVEL 
CIRCULATION CENTER (LLCC). THE INITIAL POSITION IS PLACED WITH HIGH 
CONFIDENCE BASED ON THE ANIMATED MULTI-SPECTRAL LOOP AND ANIMATED 
RADAR IMAGERY. THE INITIAL INTENSITY OF 55 KNOTS IS BASED ON RECENT 
AGENCY DVORAK CURRENT INTENSITY ESTIMATES OF T3.5 (55 KNOTS) FROM 
BOTH APRF AND PGTW. UPPER-LEVEL ANALYSIS REVEALS THE SYSTEM HAS 
STRONG EQUATORWARD OUTFLOW AND WEAKER POLEWARD OUTFLOW. 
ENVIRONMENTAL ANALYSIS SHOWS THE SYSTEM IS IN AN AREA OF LOW TO 
MODERATE (10-15 KNOT) VERTICAL WIND SHEAR (VWS) AND HAS BEEN 
TRACKING THROUGH WARM (30-31 CELSIUS) SEA SURFACE TEMPERATURES IN 
THE JOSEPH BONAPARTE GULF. TC 15S IS TRACKING TO THE SOUTHWEST AND 
WILL SHORTLY MAKE LANDFALL OVER NORTHWESTERN AUSTRALIA. AS THE 
SYSTEM TRACKS, A SUBTROPICAL RIDGE OVER CENTRAL AUSTRALIA WILL 
BUILD, CAUSING THE TRACK TO SHIFT MORE WESTWARD BETWEEN TAU 24 AND 
TAU 72. AFTER TAU 72, THE SYSTEM WILL BEGIN TO ROUND THE WESTERN 
EXTENT OF THE RIDGE AND TRACK TO THE SOUTHWEST. DEVELOPMENT WILL BE 
LIMITED THROUGH TAU 24 AS THE SYSTEM TRACKS OVER LAND. AFTER 
TRACKING BACK OVER WATER AFTER TAU 24, THE SYSTEM WILL STEADILY 
INTENSIFY, REACHING A PEAK OF 120 KNOTS BY TAU 96. DYNAMIC MODEL 
GUIDANCE IS IN GOOD AGREEMENT WITH THE FORECAST TRACK LENDING 
OVERALL HIGH CONFIDENCE IN THE JTWC FORECAST TRACK. MAXIMUM 
SIGNIFICANT WAVE HEIGHT AT 180000Z IS 15 FEET. NEXT WARNINGS AT 
180900Z, 181500Z, 182100Z AND 190300Z. REFER TO TROPICAL CYCLONE 14S

REMARKS:
181500Z POSITION NEAR 15.1S 124.8E.
TROPICAL CYCLONE (TC) 15S (MARCUS), LOCATED APPROXIMATELY 249 NM
NORTHEAST OF BROOME, AUSTRALIA, HAS TRACKED WEST-SOUTHWESTWARD AT
13 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY INDICATES THAT TC 15S IS STRADDLING THE NORTHERN 
COAST OF AUSTRALIA AND HAS CONSOLIDATED WITH IMPROVED CONVECTIVE 
BANDING WRAPPING INTO A WELL-DEFINED CENTER. THEREFORE, THERE IS 
EXCELLENT CONFIDENCE IN THE INITIAL POSITION. THE INITIAL INTENSITY 
IS ASSESSED AT 45 KNOTS BASED ON THE SLIGHT WEAKENING TREND WHILE 
TRACKING OVER LAND THROUGH 18/12Z, HOWEVER, THE PGTW 18/1430Z DVORAK 
ESTIMATE IS NOW T3.5 (55 KNOTS) REFLECTING THE SHORT-TERM 
IMPROVEMENT IN STRUCTURE AS THE SYSTEM BEGINS TO RE-EMERGE OVER 
WATER. OVERALL, ENVIRONMENTAL CONDITIONS ARE FORECAST TO BE VERY 
FAVORABLE, THEREFORE, THE SYSTEM IS EXPECTED TO RAPIDLY INTENSIFY 
THROUGH TAU 72 WITH A PEAK INTENSITY OF 125 KNOTS EXPECTED AT TAU 
96. TC 15S IS FORECAST TO TRACK GENERALLY WESTWARD THROUGH TAU 72 
ALONG THE NORTHERN PERIPHERY OF THE SUBTROPICAL RIDGE (STR) 
ENTRENCHED OVER WESTERN AUSTRALIA. AFTER TAU 72, THE SYSTEM WILL 
RECURVE SOUTHWARD AS IT ROUNDS THE STR AND TRACKS TOWARD A BREAK IN 
THE STR. DYNAMIC MODEL GUIDANCE REMAINS IN TIGHT AGREEMENT, 
THEREFORE, THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST TRACK. NEXT 
WARNINGS AT 182100Z, 190300Z, 190900Z AND 191500Z. REFER TO TROPICAL

REMARKS:
182100Z POSITION NEAR 15.2S 123.6E.
TROPICAL CYCLONE 15S (MARCUS), LOCATED APPROXIMATELY 212 NM
NORTHEAST OF BROOME, AUSTRALIA, HAS TRACKED WESTWARD AT 10 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE 
IMAGERY DEPICTS FLARING CONVECTION WITH DENSE CENTRAL OVERCAST AND 
COOLING CLOUD TOPS OVER THE LAST SIX HOURS. THERE IS HIGH CONFIDENCE 
IN THE INITIAL POSITION WHICH IS BASED ON A NOTCH FEATURE OBSERVED 
IN BOTH 181836Z 85 AND 37 GHZ SSMI IMAGES WITH NOTABLE DIFFERENCES 
IN SATELLITE FIXES; HOWEVER, ALL AVAILABLE DATA INDICATES TC 15S HAS 
REEMERGED OVER WATER. UPPER LEVEL ANALYSIS SHOWS GOOD POLEWARD AND 
EQUATORWARD OUTFLOW CHANNELS WITH A DEFINED EASTERN OUTFLOW BOUNDARY 
AGAINST THE PREDOMINANT EASTERLY FLOW ALOFT. SSTS ARE EXTREMELY WARM 
(30 TO 31 CELSIUS) AND WILL SUPPORT RAPID DEVELOPMENT OVER THE NEXT 
12 TO 24 HOURS REACHING A PEAK INTENSITY OF 130 KNOTS SOMETIME 
BEFORE TAU 72. TC 15S IS TRACKING WESTWARD ALONG THE NORTHERN 
PERIPHERY OF A SUBTROPICAL RIDGE ANCHORED OVER AUSTRALIA. TC 15S 
WILL TRACK WESTWARD UNTIL AROUND TAU 72 WHEN THE TRACK WILL SHIFT 
POLEWARD AROUND THE RIDGE AXIS. THE POLEWARD TRACK WILL TAKE TC 15S 
INTO COOLER WATERS WHICH WILL WEAKEN THE SYSTEM IN LATER TAUS. 
DYNAMIC MODEL GUIDANCE SHOWS VERY GOOD AGREEMENT LENDING HIGH 
CONFIDENCE IN THE FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 
181800Z IS 15 FEET. NEXT WARNINGS AT 190300Z, 190900Z, 191500Z AND 
192100Z. REFER TO TROPICAL CYCLONE 14S (ELIAKIM) WARNINGS (WTXS31 
PGTW) FOR SIX-HOURLY UPDATES.//

REMARKS:
190300Z POSITION NEAR 15.0S 122.8E.
TROPICAL CYCLONE 15S (MARCUS), LOCATED APPROXIMATELY 187 NM
NORTH-NORTHEAST OF BROOME, AUSTRALIA, HAS TRACKED WESTWARD AT 09
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY DEPICTS A RAPIDLY CONSOLIDATING SYSTEM WITH DEEP CONVECTIVE 
BANDING IN THE EARLY STAGE OF EYE FORMATION. THERE IS HIGH 
CONFIDENCE IN THE INITIAL POSITION WHICH IS BASED ON A NEARLY CLOSED 
OFF MICROWAVE EYE IN AN 182306Z 89 GHZ MHS IMAGE AND A SIMILAR CYAN 
RING FEATURE OBSERVED AN 182208 37GHZ COLOR COMPOSITE SSMIS IMAGE, 
INDICATIVE OF NEAR-TERM RAPID INTENSIFICATION. THE INITIAL INTENSITY 
ASSESSMENT OF 65 KNOTS REFLECTS THE IMPROVED STRUCTURE OF THE SYSTEM 
AVERAGING MULTI-AGENCY DVORAK ESTIMATES RANGING FROM T3.5 TO T4.5 
(55 TO 77 KNOTS) AND A 182203Z SATCON ESTIMATE OF 71 KNOTS. NEARBY 
SURFACE OBSERVATIONS FROM ADELE ISLAND IS REPORTING SUSTAINED WINDS 
FROM THE SOUTHEAST AROUND 45 KNOTS AND A 6 MB DROP IN MSLP TO 998 MB 
OVER THE LAST SIX HOURS. UPPER LEVEL ANALYSIS SHOWS GOOD POLEWARD 
AND EQUATORWARD OUTFLOW CHANNELS WITH A DEFINED EASTERN OUTFLOW 
BOUNDARY AGAINST THE PREDOMINANT EASTERLY FLOW ALOFT. SSTS ARE ALSO 
EXTREMELY WARM (30 TO 31 CELSIUS) WITH SIGNIFICANT OCEAN HEAT 
CONTENT, AND WILL SUPPORT RAPID DEVELOPMENT OVER THE NEXT 12 TO 24 
HOURS REACHING A PEAK INTENSITY OF 130 KNOTS SOMETIME BEFORE TAU 48. 
TC 15S IS TRACKING WESTWARD ALONG THE NORTHERN PERIPHERY OF A 
SUBTROPICAL RIDGE ANCHORED OVER AUSTRALIA. TC 15S WILL TRACK 
WESTWARD UNTIL AROUND TAU 72 WHEN THE TRACK WILL SHIFT POLEWARD 
AROUND THE RIDGE AXIS. THE POLEWARD TRACK WILL TAKE TC 15S INTO 
COOLER WATERS WHICH WILL RAPIDLY WEAKEN THE SYSTEM IN LATER TAUS. 
DYNAMIC MODEL GUIDANCE SHOWS VERY GOOD AGREEMENT LENDING HIGH 
CONFIDENCE IN THE FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 
190000Z IS 22 FEET. NEXT WARNINGS AT 190900Z, 191500Z, 192100Z AND 
200300Z. REFER TO TROPICAL CYCLONE 14S (ELIAKIM) WARNINGS (WTXS31

REMARKS:
191500Z POSITION NEAR 15.6S 120.6E.
TROPICAL CYCLONE (TC) 15S (MARCUS), LOCATED APPROXIMATELY 149 NM
NORTH-NORTHWEST OF BROOME, AUSTRALIA, HAS TRACKED WESTWARD AT 14
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE 
IMAGERY DEPICTS A RAPIDLY CONSOLIDATING SYSTEM WITH DEEP CONVECTIVE 
BANDING AND A RAGGED, 11 NM EYE, THAT INSTILLS HIGH CONFIDENCE IN 
THE INITIAL POSITION. THE INITIAL INTENSITY ESTIMATE OF 95 KNOTS 
REFLECTS THE MULTI-AGENCY DVORAK FIXES OF T4.5 TO T5.5 (77 TO 102 
KNOTS) AND A 191038Z SATCON ESTIMATE OF 95 KNOTS. ENVIRONMENTAL 
ANALYSIS SHOWS EXCELLENT POLEWARD AND EQUATORWARD OUTFLOW CHANNELS, 
LOW VERTICAL WIND SHEAR (VWS), AND WARM SSTS (30 TO 31C). ALL THESE 
FACTORS SUPPORT RAPID INTENSIFICATION OVER THE NEXT 24 HOURS. FROM 
TAU 24 TO 36, THE STORM INTENSIFIES MORE SLOWLY TO ITS PEAK 
INTENSITY OF 130 KNOTS. TC 15S WILL TRACK WESTWARD ALONG THE 
NORTHERN PERIPHERY OF A SUBTROPICAL RIDGE ANCHORED OVER AUSTRALIA 
UNTIL JUST BEFORE TAU 48 WHEN THE TRACK WILL BEGIN TO SLOWLY SHIFT 
POLEWARD AS THE CYCLONE ROUNDS THE RIDGE AXIS. AS IT BEGINS THAT 
TURN, CONDITIONS WILL BECOME LESS FAVORABLE WITH INCREASING VWS AND 
COOLING SSTS AND TC 15S WILL BEGIN TO WEAKEN, SLOWLY AT FIRST, THEN 
RAPIDLY AFTER TAU 96. DYNAMIC MODEL GUIDANCE SHOWS VERY GOOD 
AGREEMENT THROUGH TAU 72, LENDING HIGH CONFIDENCE IN THE FORECAST 
TRACK. BEYOND TAU 72, HIGH UNCERTAINTY IN THE MODEL GUIDANCE LOWERS 
CONFIDENCE IN THE FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 
191200Z IS 36 FEET. NEXT WARNINGS AT 192100Z, 200300Z, 200900Z AND 
201500Z. REFER TO TROPICAL CYCLONE 14S (ELIAKIM) WARNINGS (WTXS31

REMARKS:
192100Z POSITION NEAR 15.3S 119.2E.
TROPICAL CYCLONE 15S (MARCUS), LOCATED APPROXIMATELY 205 NM
NORTHWEST OF BROOME, AUSTRALIA, HAS TRACKED WEST-NORTHWESTWARD AT
13 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY REVEALS DEEP CONVECTIVE BANDING AND A RAGGED 10 NM 
EYE THAT INSTILLS HIGH CONFIDENCE IN THE INITIAL POSITION. THE 
INITIAL INTENSITY ESTIMATE OF 100 KNOTS IS BASED ON MULTI-AGENCY 
DVORAK CURRENT INTENSITY ESTIMATES OF T5.5 (102 KNOTS) HEDGED LOWER 
DUE TO A BRIEF PERIOD OF CLOUD FILLING IN THE EYE OBSERVED AROUND 
191800Z. ENVIRONMENTAL ANALYSIS SHOWS GOOD POLEWARD AND EQUATORWARD 
OUTFLOW CHANNELS, LOW VERTICAL WIND SHEAR (VWS), AND WARM SSTS (30 
TO 31C). ALL THESE FACTORS SUPPORT CONTINUED RAPID INTENSIFICATION 
OVER THE NEXT 24 HOURS. TC 15S WILL CONTINUE WESTWARD ALONG THE 
NORTHERN PERIPHERY OF A SUBTROPICAL RIDGE ANCHORED OVER AUSTRALIA. 
FROM TAU 24 TO 48, THE STORM INTENSIFIES MORE SLOWLY AND THEN BEGINS 
TO WEAKEN DUE TO A SLIGHT INCREASE IN NORTHEASTLY VWS AS IT BEGINS 
TO DEFLECT SOUTHWESTWARD. AS TC 15S CONTINUES POLEWARD ALONG THE 
RIDGE AXIS, CONDITIONS WILL CONTINUE TO BECOME LESS FAVORABLE WITH 
INCREASING VWS AND COOLING SSTS. RAPID WEAKENING WILL BEGIN TO OCCUR 
AFTER TAU 72, AND EXTRATROPICAL TRANSITION WILL BEGIN AT ABOUT TAU 
120. DYNAMIC MODEL GUIDANCE CONTINUES TO SHOW VERY GOOD AGREEMENT, 
LENDING HIGH CONFIDENCE IN THE FORECAST TRACK. MAXIMUM SIGNIFICANT 
WAVE HEIGHT AT 191800Z IS 38 FEET. NEXT WARNINGS AT 200300Z, 
200900Z, 201500Z AND 202100Z. REFER TO TROPICAL CYCLONE 14S

REMARKS:
200300Z POSITION NEAR 15.0S 117.7E.
TROPICAL CYCLONE 15S (MARCUS), LOCATED APPROXIMATELY 276 NM
NORTHWEST OF BROOME, AUSTRALIA, HAS TRACKED WESTWARD AT 15 KNOTS
OVER THE PAST SIX HOURS. ANIMATED VISIBLE SATELLITE IMAGERY REVEALS 
DEEP CONVECTIVE BANDING WRAPPING INTO A CLOUD-FILLED 7 NM EYE THAT 
INSTILLS HIGH CONFIDENCE IN THE INITIAL POSITION. THE INITIAL 
INTENSITY ESTIMATE OF 105 KNOTS IS BASED ON DVORAK CURRENT INTENSITY 
ESTIMATES OF T5.5 (102 KNOTS) FROM PGTW AND KNES. ENVIRONMENTAL 
ANALYSIS SHOWS GOOD POLEWARD AND EQUATORWARD OUTFLOW CHANNELS, LOW 
(LESS THAN 10 KNOTS) VERTICAL WIND SHEAR (VWS), AND WARM SSTS (30 TO 
31C). ALL THESE FACTORS SUPPORT STEADY INTENSIFICATION OVER THE NEXT 
36 HOURS AS TC 15S TRACKS WESTWARD ALONG THE NORTHERN PERIPHERY OF A 
SUBTROPICAL RIDGE ANCHORED OVER AUSTRALIA. AFTER TAU 36, THE SYSTEM 
BEGINS TO WEAKEN DUE TO A SLIGHT INCREASE IN NORTHEASTLY VWS AS IT

REMARKS:
201500Z POSITION NEAR 14.5S 114.5E.
TROPICAL CYCLONE (TC) 15S (MARCUS), LOCATED APPROXIMATELY 399 NM
NORTH-NORTHWEST OF PORT HEDLAND, AUSTRALIA, HAS TRACKED WESTWARD AT
15 KNOTS OVER THE PAST SIX HOURS. ANIMATED MSI SHOWS THE CYCLONE HAS
RE-DEVELOPED AN 11-NM SHARPLY OUTLINED EYE AS HIGHLY-SYMMETRICAL
BANDS WRAPPED EVEN TIGHTER INTO THE LOW LEVEL CIRCULATION CENTER. 
THE INITIAL POSITION IS BASED ON A MICROWAVE EYE FEATURE IN THE 
201032Z SSMIS 37GHZ IMAGE WITH HIGH CONFIDENCE. THE INITIAL 
INTENSITY OF 110 KNOTS IS BASED ON DVORAK CURRENT INTENSITY 
ESTIMATES OF 5.5 TO 6.0 AND REFLECTS THE INTENSIFICATION. TC 15S IS 
EXPECTED TO RAPIDLY INTENSIFY WITHIN THE NEXT 24 HOURS TO A PEAK OF 
130 KNOTS THEN RAPIDLY WEAKEN AFTER TAU 36 AS IT RECURVES SOUTHWARD 
ALONG THE WESTERN PERIPHERY OF THE STEERING SUBTROPICAL RIDGE TO THE 
SOUTHEAST. TC MARCUS WILL DISSIPATE AS A SIGNIFICANT TROPICAL 
CYCLONE OVER WATER BY TAU 120. DYNAMIC MODEL GUIDANCE REMAINS IN 
TIGHT AGREEMENT, LENDING HIGH CONFIDENCE IN THE JTWC FORECAST TRACK. 
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 201200Z IS 45 FEET. NEXT WARNINGS

REMARKS:
202100Z POSITION NEAR 14.6S 113.1E.
TROPICAL CYCLONE 15S (MARCUS), LOCATED APPROXIMATELY 439 NM
NORTHWEST OF PORT HEDLAND, AUSTRALIA, HAS TRACKED WESTWARD AT 14
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE 
IMAGERY (EIR) SHOWS A MATURE SYSTEM WITH A PINHOLE EYE (9 NM IN 
DIAMETER) THAT HAS FLUCTUATED BETWEEN PERIODS OF CLOUD-FILLING AND 
CLEARING OVER THE PAST 6 HOURS. THE INITIAL POSITION IS BASED ON 
THIS EYE FEATURE OBSERVED IN EIR IMAGERY WITH HIGH CONFIDENCE. THE 
INITIAL INTENSITY IS BASED ON MULTI-AGENCY DVORAK CURRENT INTENSITY 
ESTIMATES IN AGREEMENT AT T6.0 (115 KNOTS). ENVIRONMENTAL ANALYSIS 
INDICATES LOW (LESS THAN 10 KNOTS) VERTICAL WIND SHEAR (VWS), WARM 
SSTS (29 TO 30 CELSIUS), AND HIGH OCEAN HEAT CONTENT (OHC), WHICH 
ALL FAVOR INTENSIFICATION. TC 15S IS EXPECTED TO CONTINUE TO 
STEADILY INTENSIFY OVER THE NEXT 24 HOURS AS IT TRACKS WESTWARD 
UNDER THE INFLUENCE OF THE SUBTROPICAL RIDGE OVER AUSTRALIA. FROM 
TAU 24 TO TAU 48, INTENSITY WILL GRADUALLY WEAKEN AS TC 15S DEFLECTS 
TO THE SOUTHEAST AND ENCOUNTERS INCREASED VWS AND DECREASED OHC. 
AFTER TAU 48, TC 15S WILL RAPIDLY WEAKEN AS IT ROUNDS THE RIDGE AXIS 
AND TRACKS POLEWARD INTO STEADILY DECREASING SSTS AND UNFAVORABLE 
VWS. THESE UNFAVORABLE FACTORS WILL LEAD TO DISSIPATION OVER WATER 
BY TAU 120. DYNAMIC MODEL GUIDANCE IS NOT SHOWING STRONG EVIDENCE OF 
AN EXTRA-TROPICAL TRANSITION SCENARIO AND REMAINS IN TIGHT 
AGREEMENT, LENDING HIGH CONFIDENCE IN THE JTWC FORECAST TRACK.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 201800Z IS 47 FEET. NEXT
WARNINGS AT 210300Z, 210900Z, 211500Z AND 212100Z. REFER TO TROPICAL

REMARKS:
210300Z POSITION NEAR 14.6S 111.7E.
TROPICAL CYCLONE 15S (MARCUS), LOCATED APPROXIMATELY 479 NM
NORTH-NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED WESTWARD AT
15 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED MULTI-SPECTRAL 
SATELLITE IMAGERY (EIR) DEPICTS DEEP CONVECTION WRAPPING INTO A 
PINHOLE EYE (8 NM IN DIAMETER) THAT CONTINUES TO FLUCTUATE BETWEEN 
PERIODS OF CLOUD-FILLING AND CLEARING. THE INITIAL POSITION IS 
PLACED WITH HIGH CONFIDENCE BASED ON THE EYE FEATURE IN THE EIR 
IMAGERY AND IS SUPPORTED BY A 202317Z 91GHZ SSMI/S MICROWAVE IMAGE. 
THE AFOREMENTIONED MICROWAVE IMAGE SHOWS DEEP CONVECTIVE BANDING 
ENCIRCLING THE ENTIRE EYE FEATURE. THE INITIAL INTENSITY OF 120 
KNOTS IS BETWEEN MULTI-AGENCY DVORAK CURRENT INTENSITY ESTIMATES OF 
T6.0 (115 KNOTS) AND A RECENT SATCON ESTIMATE OF 125 KNOTS. UPPER 
LEVEL ANALYSIS SHOWS THE SYSTEM HAS STRONG POLEWARD AND EQUATORWARD 
OUTFLOW CHANNELS. ENVIRONMENTAL ANALYSIS REVEALS THE SYSTEM IS IN AN 
AREA OF LOW (5-10 KNOTS) VERTICAL WIND SHEAR (VWS) AND IS TRACKING 
THROUGH WARM (29-30 CELSIUS) SEA SURFACE TEMPERATURES.
TC 15S IS CURRENTLY TRACKING WESTWARD UNDER THE INFLUENCE OF THE 
SUBTROPICAL RIDGE ANCHORED OVER CENTRAL AUSTRALIA. TC MARCUS IS 
FORECAST TO INTENSIFY OVER THE NEXT 24 HOURS, PEAKING AT 130 KNOTS 
BY TAU 24. THE SYSTEM TRACK IS SHIFTING TO THE SOUTHWEST AS IT 
BEGINS TO ROUND THE WESTERN EXTENT OF THE SUBTROPICAL RIDGE. AROUND 
TAU 48 THE SYSTEM WILL CROSS THE RIDGE AXIS AND RECURVE TO THE 
SOUTHEAST. INTENSITY WILL GRADUALLY WEAKEN AFTER TAU 24 AS TC 15S 
ENCOUNTERS A LESS FAVORABLE ENVIRONMENT OF INCREASED VWS AND 
DECREASED OHC. AFTER TAU 48, TC 15S WILL BEGIN TO RAPIDLY WEAKEN AS 
IT TRACKS INTO STEADILY DECREASING SSTS AND UNFAVORABLE VWS. THESE 
UNFAVORABLE FACTORS WILL LEAD TO TC 15S DISSIPATING OVER WATER BY 
TAU 120. AVAILABLE DYNAMIC MODEL GUIDANCE IS IN TIGHT AGREEMENT WITH 
THE FORECAST TRACK LENDING HIGH CONFIDENCE IN THE JTWC FORECAST 
TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 210000Z IS 48 FEET. NEXT
WARNINGS AT 210900Z, 211500Z, 212100Z AND 220300Z.//

REMARKS:
212100Z POSITION NEAR 15.8S 108.0E.
TROPICAL CYCLONE 15S (MARCUS), LOCATED APPROXIMATELY 521 NM
NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED WEST-SOUTHWESTWARD
AT 12 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY DEPICTS A TIGHTLY WOUND SYSTEM WITH DEEP BANDING 
CONVECTION WRAPPING INTO A 17 NM EYE FEATURE, LENDING HIGH 
CONFIDENCE TO THE INITIAL POSITION. THE INITIAL INTENSITY IS 
ASSESSED AT 140 KNOTS WHICH IS BASED ON MULTI-AGENCY DVORAK 
ESTIMATES FROM ALL AGENCIES REPORTING T7.0 (140 KNOTS). UPPER-LEVEL 
ANALYSIS SHOWS VERY LOW VERTICAL WIND SHEAR AND EXCELLENT RADIAL 
OUTFLOW ALOFT FEEDING INTO BOTH EQUATORWARD AND POLEWARD OUTFLOW 
CHANNELS. A POINT SOURCE ANALYZED TO THE NORTHEAST IS CREATING SOME 
CONVERGENCE AND AN OUTFLOW BOUNDARY ON THIS SIDE. SSTS IN THE REGION 
ARE ALSO VERY SUPPORTIVE NEAR 30 CELSIUS, HOWEVER OCEAN HEAT CONTENT 
IS BEGINNING TO DIMINISH SUGGESTING TC 15S WILL NOT INTENSIFY 
FURTHER. TC 15S IS NOW TRACKING WEST-SOUTHWEST AS IT ROUNDS THE 
WESTERN EDGE OF A SUBTROPICAL RIDGE. THE TRACK IS FORECAST TO SHIFT 
FURTHER POLEWARD OVER THE NEXT 12 TO 24 HOURS INTO COOLER WATERS. 
INITIALLY SSTS DECREASE ONLY MARGINALLY, HOWEVER BEYOND TAU 36 THE 
TEMPERATURE GRADIENT DECREASES RAPIDLY INTO UNFAVORABLE CONDITIONS.  
NEAR TAU 48 TC 15S WILL APPROACH THE MIDLATITUDE WESTERLY JET AND 
VERTICAL WIND SHEAR WILL BEGIN RAPIDLY INCREASING. DUE TO THESE 
UNFAVORABLE ENVIRONMENTAL CONDITIONS TC 15S IS FORECAST TO WEAKEN 
RAPIDLY AFTER TAU 48. TC 15S WILL TURN SOUTHEASTWARD AND DISSIPATE 
OVER WATER SOMETIME BEFORE TAU 96.  DYNAMIC MODEL GUIDANCE CONTINUES 
TO SHOW GOOD AGREEMENT WITH TIGHT GROUPING BETWEEN SOLUTIONS.  
OVERALL THERE IS HIGH CONFIDENCE IN THE FORECAST TRACK. MAXIMUM 
SIGNIFICANT WAVE HEIGHT AT 211800Z IS 52 FEET. NEXT WARNINGS AT 
220300Z, 220900Z, 221500Z AND 222100Z.//

REMARKS:
220900Z POSITION NEAR 17.1S 106.4E.
TROPICAL CYCLONE (TC) 15S (MARCUS), LOCATED APPROXIMATELY 541 NM
NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTHWESTWARD AT
11 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY DEPICTS A 12 NM EYE SURROUNDED BY DEEP CONVECTION 
THAT APPEARS TO BE WARMING SLIGHTLY OVER THE LAST SEVERAL HOURS. THE 
INITIAL INTENSITY IS ASSESSED AT 140 KNOTS WHICH IS BASED ON PGTW 
AND KNES CURRENT INTENSITY DVORAK ESTIMATES OF T7.0 (140 KNOTS). 
RECENT DVORAK DATA-T ANALYSES OF T6.5 SUGGEST THAT TC 15S IS 
BEGINNING TO SHOW EARLY SIGNS OF WEAKENING. ENVIRONMENTAL ANALYSIS 
SHOWS VERY LOW VERTICAL WIND SHEAR (VWS), EXCELLENT EQUATORWARD AND 
POLEWARD OUTFLOW, AND WARM SSTS (28-29C). TC 15S IS NOW TRACKING 
SOUTHWESTWARD AS IT ROUNDS THE WESTERN EDGE OF A SUBTROPICAL RIDGE. 
THE TRACK IS FORECAST TO SHIFT FURTHER POLEWARD AND BRING TC 15S 
INTO AN UNFAVORABLE ENVIRONMENT WITH INCREASING VWS AND COOLING 
SSTS. THE SYSTEM IS FORECAST TO WEAKEN, SLOWLY AT FIRST, THEN MORE 
RAPIDLY AS THE CYCLONE DISSIPATES OVER WATER BY AROUND TAU 72. 
DYNAMIC MODEL GUIDANCE CONTINUES TO SHOW GOOD AGREEMENT WITH TIGHT 
GROUPING BETWEEN SOLUTIONS, LENDING TO HIGH CONFIDENCE IN THE 
FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 220600Z IS 52 
FEET. NEXT WARNINGS AT 221500Z, 222100Z, 230300Z AND 230900Z.//

222100Z POSITION NEAR 19.4S 106.0E.
TROPICAL CYCLONE 15S (MARCUS), LOCATED APPROXIMATELY 501 NM WEST-

SOUTHWESTWARD AT 12 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED 
INFRARED SATELLITE IMAGERY DEPICTS A HIGHLY SYMMETRIC SYSTEM WITH A 
PREVIOUSLY OBSERVABLE EYE FEATURE NOW COMPLETELY CLOUD FILLED. 
RECENT MICROWAVE IMAGERY SHOWS THAT TC 15S IS UNDERGOING AN EYEWALL

INDISTINGUISHABLE IN AN 221507Z 89 GHZ MHS IMAGE AND AN OUTER RING 
OF CONVECTION NEARLY CLOSED OFF WITH EXCEPTION OF THE EASTERN MOST

INTENSITY IS ASSESSED AT 120 KNOTS WHICH IS BASED ON MULTI-AGENCY 
CURRENT INTENSITY DVORAK ESTIMATES RANGING FROM T 6.0 TO T6.5 (127 
TO 115 KNOTS). UPPER-LEVEL ANALYSIS SHOWS VERY LOW WIND SHEAR AND 
EXCELLENT RADIAL OUTFLOW DIRECTLY ABOVE THE SYSTEM FEEDING INTO A 
STRONG POLEWARD OUTFLOW CHANNEL. SSTS ARE ALSO VERY WARM NEAR 28 
CELSIUS. TC 15S IS TRACKING SOUTH-SOUTHWESTWARD ALONG THE WESTERN 
BOUNDARY OF SUBTROPICAL RIDGE ANCHORED OVER AUSTRALIA. TC 15S IS 
FORECAST TO CONTINUE TRACKING GENERALLY SOUTHWARD AND INTO COOLER 
WATERS TURNING SLIGHTLY SOUTHEASTWARD AFTER TAU 48. VERTICAL WIND 
SHEAR IS ALSO FORECAST TO INCREASE AS TC 15S APPROACHES THE MID 
LATITUDE WESTERLY JET. DEGRADING ENVIRONMENTAL CONDITIONS WILL 
RAPIDLY WEAKEN THE SYSTEM AND TC 15S WILL FULLY DISSIPATE OVER WATER 
SOMETIME BEFORE TAU 72. DYNAMIC MODEL GUIDANCE CONTINUES TO SHOW 
GOOD AGREEMENT, LENDING HIGH CONFIDENCE TO THE FORECAST TRACK.      
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 221800Z IS 35 FEET. NEXT

NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTHWARD AT 11
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY DEPICTS HIGHLY SYMMETRICAL SPIRAL BANDING WITH DENSE 
OVERCAST OBSCURING THE LOW LEVEL CIRCULATION CENTER. RECENT 
MICROWAVE IMAGERY SHOWS THAT TC 15S RECENTLY UNDERWENT AN EYEWALL 
REPLACEMENT CYCLE WITH THE INNER EYEWALL MOSTLY DISSIPATED WITH ONLY 
AN AREA OF WEAK CENTRAL CONVECTION REMAINING OBSERVED IN A 222300Z 
91 GHZ SSMIS IMAGE ALSO SHOWING THE NEWLY FORMED OUTER RING OF 
CONVECTION WITH THE STRONGEST CONVECTION LOCATED ON THE SOUTHERN 
SEMICIRCLE. THE INITIAL INTENSITY IS ASSESSED AT 110 KNOTS WHICH IS 
BASED ON MULTI-AGENCY CURRENT INTENSITY DVORAK ESTIMATES RANGING 
FROM T5.5 TO T6.0 (102 TO 115 KNOTS). UPPER-LEVEL ANALYSIS SHOWS 
VERY LOW WIND SHEAR AND EXCELLENT RADIAL OUTFLOW DIRECTLY ABOVE THE 
SYSTEM FEEDING INTO A STRONG POLEWARD OUTFLOW CHANNEL. SSTS ARE ALSO 
VERY WARM NEAR 28 CELSIUS. TC 15S IS TRACKING SOUTH-SOUTHWESTWARD 
ALONG THE WESTERN BOUNDARY OF SUBTROPICAL RIDGE ANCHORED OVER 
AUSTRALIA. TC 15S IS FORECAST TO CONTINUE TRACKING GENERALLY 
SOUTHWARD AND INTO COOLER WATERS TURNING SLIGHTLY SOUTHEASTWARD 
AFTER TAU 48. VERTICAL WIND SHEAR IS ALSO FORECAST TO INCREASE AS TC 
15S APPROACHES THE MID LATITUDE WESTERLY JET. DEGRADING 
ENVIRONMENTAL CONDITIONS WILL RAPIDLY WEAKEN THE SYSTEM AND TC 15S 
WILL FULLY DISSIPATE OVER WATER BY TAU 48. DYNAMIC MODEL GUIDANCE 
CONTINUES TO SHOW GOOD AGREEMENT, LENDING HIGH CONFIDENCE TO THE 
FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 230000Z IS 32 
FEET. NEXT WARNINGS AT 230900Z, 231500Z, 232100Z AND 240300Z.//

ESTIMATES OF T4.0 (65 KNOTS) FROM BOTH PGTW AND KNES, AND AUTOMATED 
INTENSITY ESTIMATES FROM CIMSS OF T3.9. TC 15S IS RAPIDLY WEAKENING 
AS IT CONTINUES TO TRACK SOUTHEASTWARD ALONG THE WESTERN PERIPHERY 
OF A DEEP SUBTROPICAL RIDGE OVER WESTERN AUSTRALIA IN A HIGH VWS 
ENVIRONMENT. THE SYSTEM IS FORECAST TO CONTINUE THIS SOUTHEASTWARD 
TRACK THROUGH THE DURATION OF THE FORECAST PERIOD UNDER THE 
INFLUENCE OF THE STEERING RIDGE WHILE CONTINUING TO WEAKEN AS IT 
PASSES OVER PROGRESSIVELY COOLER WATER AND INTO INCREASING VERTICAL 
WIND SHEAR. TC MARCUS IS EXPECTED TO DISSIPATE OVER WATER WITHIN THE 
NEXT 24 TO 36 HOURS. FORECAST MODEL GUIDANCE REMAINS IN STRONG 
AGREEMENT, LENDING HIGH CONFIDENCE TO THE CURRENT JTWC FORECAST.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 240000Z IS 24 FEET. NEXT
WARNINGS AT 240900Z, 241500Z, 242100Z AND 250300Z.//
