Tropical Cyclone Nora
WTPS21 PGTW 211830
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
145 NM EITHER SIDE OF A LINE FROM 9.6S 135.5E TO 13.2S 138.4E
WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 25 TO 30 KNOTS. METSAT
IMAGERY AT 211800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 10.0S 135.9E. THE SYSTEM IS MOVING EAST-SOUTHEASTWARD AT 06
KNOTS.
2. REMARKS:
THE AREA OF CONVECTION (INVEST 94P) PREVIOUSLY LOCATED NEAR 8.4S 
136.5E, IS NOW LOCATED NEAR 10.0S 135.9E, APPROXIMATELY 150 NM NORTH-
NORTHWEST OF GOVE AIRPORT, AUSTRALIA. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY AND A 211208Z 89GHZ AMSU MICROWAVE IMAGE DEPICTS 
FLARING DEEP CONVECTION BEGINNING TO WRAP INTO A RAPIDLY 
CONSOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC). INVEST 94P HAS 
MOVED INTO AN AREA OF LOW-MODERATE (10-20KT) VERTICAL WIND SHEAR 
WITH VERY STRONG DIVERGENCE ALOFT. SEA SURFACE TEMPERATURES ARE 
CONDUCIVE TO DEVELOPMENT (28-30 CELSIUS) BOTH IN THE ARAFURA SEA AND 
TO THE SOUTHEAST IN THE GULF OF CARPENTARIA WHERE INVEST 94P IS 
EXPECTED TO TRACK. GLOBAL MODELS ARE IN GOOD AGREEMENT THE SYSTEM 
WILL DEVELOP IN THE NEXT 12 TO 24 HOURS TRACKING TO THE SOUTHEAST 
AND IS EXPECTED TO BE SHORT LIVED AS IT MAKES LANDFALL OVER 
NORTHWESTERN QUEENSLAND. HOWEVER, WITH FAVORABLE ENVIRONMENTAL 
CONDITIONS THE POTENTIAL FOR RAPID DEVELOPMENT INTO A SIGNIFICANT 
TROPICAL CYCLONE IS HIGH. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED 
TO BE NEAR 998 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY 
221830Z.//

REMARKS:
220900Z POSITION NEAR 10.2S 135.8E.
TROPICAL CYCLONE (TC) 16P (SIXTEEN), LOCATED APPROXIMATELY 309 NM
EAST-NORTHEAST OF DARWIN, AUSTRALIA, HAS TRACKED EAST-
SOUTHEASTWARD AT 03 KNOTS OVER THE PAST SIX HOURS. ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY DEPICTS SUSTAINED CONVECTION OVER AN 
OBSCURED LOW LEVEL CIRCULATION CENTER CAUSING LOW CONFIDENCE IN THE 
INITIAL POSITION. A PARTIAL PASS FROM A 220054Z ASCAT IMAGE SHOWS A 
LARGE AREA OF 30-35 KNOT WINDS ON THE WESTERN SEMICIRCLE. THE 
INITIAL INTENSITY IS ASSESSED AT 35 KNOTS WHICH IS BASED ON THE 
ASCAT PASS AND A DVORAK INTENSITY ESTIMATE OF T2.5 (35 KNOTS) FROM 
ADRM. ENVIRONMENTAL ANALYSIS SHOWS MODERATE VERTICAL WIND SHEAR 
(VWS), EXCELLENT EQUATORWARD AND POLEWARD OUTFLOW, AND WARM SSTS (29-
30C). TC 16P IS BEING STEERED BY A NORTH-SOUTH ORIENTED RIDGE TO ITS 
EAST. THE STORM IS FORECAST TO TRACK SOUTHEASTWARD THROUGH TAU 36 
BEFORE TURNING TO THE SOUTH AND EVENTUALLY TO THE WEST AS A RIDGE 
BUILDS IN OVER CENTRAL AUSTRALIA.  THE STORM WILL SLOWLY INTENSIFY 
AT FIRST, THEN MORE RAPIDLY AS VWS DECREASES. THE PEAK INTENSITY IS 
ESTIMATED AT 85 KNOTS AT TAU 48. DYNAMIC MODEL GUIDANCE HAS A RANGE 
OF POSSIBLE OUTCOMES WITH THE BULK OF THE GUIDANCE SIMILAR TO THE 
FORECAST TRACK BUT SEVERAL MODELS CONTINUE A SOUTHEAST TRACK THROUGH 
THE ENTIRE FORECAST PERIOD, RESULTING IN LOW CONFIDENCE IN THE JTWC 
FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 220600Z IS 9 
FEET. NEXT WARNINGS AT 221500Z, 222100Z, 230300Z AND 230900Z. THIS 
CANCELS AND SUPERSEDES REF A (WTPS21 PGTW 211830).//

35 KNOTS IS BASED ON A DVORAK ESTIMATE OF T2.5 (35 KNOTS) FROM ADRM, 
COUPLED WITH A 220054Z ASCAT IMAGE SHOWING A LARGE AREA OF 30-35 
KNOT WINDS IN THE WESTERN SEMICIRCLE. ENVIRONMENTAL ANALYSIS SHOWS 
MODERATE (10-20 KNOT) VERTICAL WIND SHEAR (VWS), EXCELLENT 
EQUATORWARD AND POLEWARD OUTFLOW, AND WARM SSTS (29-30C). TC 16P IS 
BEING STEERED BY A NORTH-SOUTH ORIENTED RIDGE TO ITS EAST. THE STORM 
IS FORECAST TO TRACK SOUTHEASTWARD THROUGH TAU 36 BEFORE TURNING TO 
THE SOUTH AND EVENTUALLY TO THE WEST AS A RIDGE BUILDS IN OVER 
CENTRAL AUSTRALIA. THE STORM WILL INTENSIFY, SLOWLY AT FIRST, THEN 
MORE RAPIDLY AS VWS DECREASES. THE PEAK INTENSITY IS ESTIMATED AT 85 
KNOTS BY TAU 48. DYNAMIC MODEL GUIDANCE HAS A LARGE SPREAD, WITH 
SEVERAL MODELS BRINGING IT SOUTHEAST INTO THE CAPE OF YORK AND OTHER 
MODELS TURNING IT BACK TO THE WEST AFTER COMING ASHORE IN THE 
SOUTHERN GULF OF CARPENTARIA. THIS SPREAD IS LEADING TO LOW 
CONFIDENCE IN THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE 
HEIGHT AT 221200Z IS 10 FEET. NEXT WARNINGS AT 222100Z, 230300Z, 
230900Z AND 231500Z.//

REMARKS:
222100Z POSITION NEAR 10.1S 136.8E.
TROPICAL CYCLONE 16P (NORA), LOCATED APPROXIMATELY 365 NM
EAST-NORTHEAST OF DARWIN, AUSTRALIA, HAS TRACKED EAST-
NORTHEASTWARD AT 02 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED 
INFRARED SATELLITE IMAGERY DEPICTS FORMATIVE BANDING CONVECTION 
RAPIDLY CONSOLIDATING AROUND THE LOW LEVEL CIRCULATION CENTER. A 
221901Z 91 GHZ SSMIS IMAGE SHOWS DEEP CONVECTIVE BANDS ON THE 
WESTERN AND NORTHERN EDGES WRAPPING AROUND A BROAD CIRCULATION. THE 
CORRESPONDING 37GHZ IMAGE SHOWS A MICROWAVE EYE BEGINNING TO TAKE 
HOLD. THE INITIAL INTENSITY IS ASSESSED AT 45 KNOTS WHICH IS HEDGED 
TOWARD THE HIGHER END OF MULTI-AGENCY DVORAK ESTIMATES RANGING FROM 
T2.5 TO T3.0 (35 TO 45 KNOTS) BASED ON THE RAPIDLY CONSOLIDATING 
CONVECTIVE STRUCTURE AND A 221557Z SATCON ESTIMATE OF 46 KNOTS. 
UPPER-LEVEL ANALYSIS SHOWS A STARK IMPROVEMENT IN VERTICAL WIND 
SHEAR OVER THE LAST SIX HOURS AND EXCELLENT DIFFLUENCE DUE TO A 
POINT SOURCE ANALYZED JUST ABOVE THE SYSTEM. SSTS IN THE REGION ARE 
EXTREMELY WARM NEAR 30 CELSIUS WITH NOTABLE OCEANIC HEAT CONTENT IN 
THE ARAFURA SEA EXTENDING INTO THE GULF OF CARPENTARIA. TC 16P IS 
CURRENTLY TRACKING EASTWARD IN A WEAK STEERING ENVIRONMENT. A WEAK 
RIDGE IS BUILDING JUST EAST OF TC 16S WHICH WILL SHIFT THE TRACK 
INCREASINGLY MORE SOUTHWARD OVER THE NEXT 48 HOURS. VERY FAVORABLE 
UPPER-LEVEL CONDITIONS WORKING IN CONCERT WITH THE WARM WATERS WILL 
FAVOR THE RAPID DEVELOPMENT OF TC 16P IN THE NEAR TERM, REACHING A 
PEAK INTENSITY OF 120 KNOTS BY TAU 36. THEREAFTER, TC 16P WILL BEGIN 
WEAKENING AS IT NEARS LAND AND SLOWS DOWN AS A SUBTROPICAL RIDGE 
CURRENTLY TO THE SOUTHWEST WILL BUILD IN SOUTH OF TC 16P AND SHIFT 
THE TRACK WEST-SOUTHWARD IN THE EXTENDED PERIOD. TC 16S WILL MAKE 
LANDFALL JUST AFTER TAU 96 AND WILL WEAKEN SIGNIFICANTLY AS IT 
TRACKS OVER THE CONTINENT. DYNAMIC MODEL GUIDANCE IS SHOWING SOME 
IMPROVEMENT, BUT A LARGE DEGREE OF UNCERTAINTY REMAINS AS THE LEVEL 
OF INFLUENCE THE EASTWARD RIDGE WILL HAVE IN THE SHORT TERM IS 
UNKNOWN. THE MESOSCALE MODELS FAVOR A TRACK MORE EASTWARD WHILE THE 
GLOBAL MODELS FAVOR A WESTWARD TRACK KEEPING THE SYSTEM OVER OPEN 
WATER LONGER. THE JTWC FORECAST TRACK IS HEDGED TOWARD THE GLOBAL 
SOLUTIONS TAKING INTO ACCOUNT A MORE PRONOUNCED EASTERN RIDGE, 
HOWEVER, DUE TO THESE UNCERTAINTIES THERE IS OVERALL LOW CONFIDENCE 
IN THE FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 221800Z IS 
15 FEET. NEXT WARNINGS AT 230300Z, 230900Z, 231500Z AND 232100Z.//

REMARKS:
230300Z POSITION NEAR 10.2S 137.2E.
TROPICAL CYCLONE 16P (NORA), LOCATED APPROXIMATELY 386 NM EAST-
NORTHEAST OF DARWIN, AUSTRALIA, HAS TRACKED EASTWARD AT 04 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
DEPICTS DEEP BANDING CONVECTION RAPIDLY CONSOLIDATING AROUND THE LOW 
LEVEL CIRCULATION CENTER STRUGGLING TO FORM AN EYE. A 222116Z 37 GHZ 
SSMIS IMAGE SHOWS A WEAK LOW LEVEL MICROWAVE EYE FEATURE. THE 
INITIAL INTENSITY IS ASSESSED AT 55 KNOTS WHICH IS BASED ON RECENT 
DVORAK ESTIMATES OF T3.5 (55 KNOTS) FROM PGTW AND ADRM. NEARBY SHIP 
AND SURFACE OBSERVATIONS FROM CAPE WESSEL INDICATE A SHARP INCREASE 
IN SUSTAINED WINDS AROUND 35 KNOTS WITH A CORRESPONDING DECREASE IN 
MSLP TO 997 MB. UPPER-LEVEL ANALYSIS SHOWS A VERY FAVORABLE WIND 
SHEAR ENVIRONMENT WITH EXCELLENT DIFFLUENCE DUE TO A POINT SOURCE 
ANALYZED JUST ABOVE THE SYSTEM. SSTS IN THE REGION ARE ALSO 
EXTREMELY WARM NEAR 30 CELSIUS WITH NOTABLE OCEANIC HEAT CONTENT IN 
THE ARAFURA SEA EXTENDING INTO THE GULF OF CARPENTARIA. TC 16P IS 
CURRENTLY TRACKING SLOWLY EASTWARD IN A WEAK STEERING ENVIRONMENT. A 
WEAK RIDGE IS BUILDING JUST EAST OF TC 16S WILL SHIFT THE TRACK 
INCREASINGLY MORE SOUTHWARD OVER THE NEXT 48 HOURS. VERY FAVORABLE 
UPPER-LEVEL CONDITIONS WORKING IN CONCERT WITH THE WARM WATERS WILL 
FAVOR THE RAPID DEVELOPMENT OF TC 16P IN THE NEAR TERM, REACHING A 
PEAK INTENSITY OF 120 KNOTS BY TAU 36. THEREAFTER, TC 16P WILL BEGIN 
WEAKENING AS IT NEARS LAND AND SLOWS DOWN AS A SUBTROPICAL RIDGE 
CURRENTLY TO THE SOUTHWEST WILL BUILD IN SOUTH OF TC 16P AND SHIFT 
THE TRACK WEST-SOUTHWESTWARD IN THE EXTENDED PERIOD. TC 16S WILL 
MAKE LANDFALL JUST BEFORE TAU 96 AND WILL WEAKEN SIGNIFICANTLY AS IT 
TRACKS OVER THE CONTINENT. DYNAMIC MODEL GUIDANCE IS SHOWING SOME 
IMPROVEMENT, BUT A LARGE DEGREE OF UNCERTAINTY REMAINS AS THE LEVEL 
OF INFLUENCE THE EASTWARD RIDGE WILL HAVE IN THE SHORT TERM IS 
UNKNOWN. THE MESOSCALE MODELS FAVOR A TRACK MORE EASTWARD WHILE THE 
GLOBAL MODELS FAVOR A WESTWARD TRACK KEEPING THE SYSTEM OVER OPEN 
WATER AND UNHINDERED BY LAND A BIT LONGER. THE JTWC FORECAST TRACK 
IS HEDGED TOWARD THE GLOBAL SOLUTIONS TAKING INTO ACCOUNT A MORE 
PRONOUNCED EASTERN RIDGE, HOWEVER, DUE TO THESE UNCERTAINTIES THERE 
IS OVERALL LOW CONFIDENCE IN THE FORECAST TRACK. MAXIMUM SIGNIFICANT 
WAVE HEIGHT AT 230000Z IS 18 FEET. NEXT WARNINGS AT 230900Z, 
231500Z, 232100Z AND 240300Z.//

REMARKS:
230900Z POSITION NEAR 11.0S 138.5E.
TROPICAL CYCLONE 16P (NORA), LOCATED APPROXIMATELY 438 NM EAST-
NORTHEAST OF DARWIN, AUSTRALIA, HAS TRACKED SOUTHEASTWARD AT 13
KNOTS OVER THE PAST SIX HOURS. THE CURRENT POSITION IS BASED ON 
RADAR IMAGERY FROM GOVE, AUSTRALIA, RECENT SATELLITE FIXES FROM 
MULTIPLE REPORTING AGENCIES AND A PARTIAL 230607Z SSMI 37 GHZ 
MICROWAVE IMAGE SHOWING A CLEAR CENTER FEATURE. THE CURRENT 
INTENSITY IS CONSISTENT WITH A CONSENSUS OF SUBJECTIVE DVORAK 
CURRENT INTENSITY ESTIMATES AND AUTOMATED INTENSITY FIX DATA FROM 
CIMSS AND CIRA. TC 16S HAS TURNED TOWARD THE SOUTHEAST AND 
ACCELERATED OVER THE PAST SIX HOURS UNDER THE STEERING INFLUENCE OF 
AN EXTENSION OF A NEAR-EQUATORIAL RIDGE TO THE NORTHEAST. STORM 
STRUCTURE CONTINUES TO IMPROVE AS THE SYSTEM INTENSIFIES, WITH DEEP 
CONVECTION FLARING AROUND A DEVELOPING EYEWALL EVIDENT IN MICROWAVE 
SATELLITE IMAGERY AND RADAR DATA. TC 16S IS EXPECTED TO TRACK 
POLEWARD UNDER THE CONTINUED INFLUENCE OF THE CURRENT STEERING RIDGE 
OVER THE NEXT 72 HOURS. AROUND TAU 72, THE SYSTEM WILL ENTER A 
COMPETING STEERING ENVIRONMENT AS A SUBTROPICAL RIDGE BUILDING TO 
THE SOUTH EXERTS AN INCREASING INFLUENCE ON STORM MOTION. SLOW 
FORWARD MOTION IS EXPECTED IN THE 72 TO 96 HOUR TIME FRAME AS THE 
PRIMARY STEERING MECHANISM TRANSITIONS TO THE SUBTROPICAL RIDGE, 
WITH ACCELERATION WESTWARD LIKELY THEREAFTER. RAPID INTENSIFICATION 
IS ANTICIPATED OVER THE NEXT 24 TO 36 HOURS AS TC 16S PASSES OVER 
VERY WARM WATER IN THE GULF OF CARPENTARIA AND UPPER-LEVEL FLOW 
SUPPORTS. WEAKENING IS EXPECTED AFTER TAU 36 AS THE UPPER-LEVEL FLOW 
PATTERN BECOMES LESS FAVORABLE. TC 16S WILL DISSIPATE BY TAU 120 AS 
IT MOVES INLAND. NUMERICAL MODELS ARE IN GOOD GENERAL AGREEMENT WITH 
THE POLEWARD TRACK SCENARIO THROUGH TAU 72, BUT DIVERGE IN THE 
EXTENDED PERIOD DUE TO DIFFERING DEPICTIONS OF THE EVOLUTION OF THE 
CURRENT AND ANTICIPATED STEERING RIDGE. THE CURRENT FORECAST LIES 
CLOSE TO THE MAJORITY SOLUTION AND THE MULTI-MODEL CONSENSUS WITH 
HIGH CONFIDENCE THROUGH LANDFALL AND LOW CONFIDENCE IN THE EXTENDED 
PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 230600Z IS 20 FEET. NEXT

REMARKS:
232100Z POSITION NEAR 12.2S 139.7E.
TROPICAL CYCLONE (TC) 16P (NORA), LOCATED APPROXIMATELY 478 NM 
NORTHWEST OF CAIRNS, AUSTRALIA, HAS TRACKED SOUTHEASTWARD AT 8 KNOTS 
OVER THE PAST SIX HOURS. ENHANCED INFRARED IMAGERY SHOWS THAT TC 
NORA HAS CEASED ITS RAPID INTENSIFICATION PHASE, AT LEAST 
TEMPORARILY, WITH THE SYSTEM STRUGGLING TO MAINTAIN AN EYE. THE 
INITIAL POSITION IS BASED ON ANALYSIS OF THE INFRARED IMAGERY, AS 
WELL AS A 231715 SSMI 37 GHZ MICROWAVE IMAGE, DEPICTING A WEAK 
MICROWAVE EYE FEATURE DISPLACED SOMEWHAT TO THE NORTHEAST FROM WHERE 
THE IR WOULD SUGGEST THE LLCC WOULD BE. THIS ASSESSMENT IS SUPPORTED 
BY ANALYSIS OF RADAR IMAGERY FROM THE GOVE, AUSTRALIA RADAR SITE. 
THE INITIAL INTENSITY REMAINS AT 95 KNOTS, CONSISTENT WITH 
SUBJECTIVE DVORAK CURRENT INTENSITY ESTIMATES RANGING FROM T5.5 (102 
KNOTS) TO T5.0 (90 KNOTS) AND AUTOMATED INTENSITY GUIDANCE FROM 
CIMSS OF T5.0. TC 16P HAS TRACKED SOUTHEASTWARD OVER THE PAST SIX 
HOURS ALONG THE WESTERN PERIPHERY OF A NEAR EQUATORIAL RIDGE (NER) 
CENTERED OVER EASTERN NEW GUINEA. AS PREVIOUSLY MENTIONED, INTENSITY 
HAS PLATEAUED OVER THE PAST 12 HOURS, LIKELY DUE TO AN EYEWALL 
REPLACEMENT CYCLE AS WELL AS RELATIVELY WEAK UPPER-LEVEL OUTFLOW. TC 
16P IS FORECAST TO CONTINUE TRACKING SOUTH-SOUTHEASTWARD UNDER THE 
STEERING INFLUENCE OF THE NER OVER THE NEXT 36 HOURS. AROUND TAU 48, 
THE SYSTEM WILL SLOW DOWN AND BECOME NEARLY QUASI-STATIONARY AS IT 
ENTERS A WEAK STEERING ENVIRONMENT BETWEEN THE NER AND A BUILDING 
SUBTROPICAL RIDGE (STR) TO THE SOUTH. BEYOND TAU 72, TC 16P WILL 
ACCELERATE WESTWARD AS THE STR BECOMES THE PRIMARY STEERING 
MECHANISM THROUGH THE REMAINDER OF THE FORECAST. A SHORT PERIOD OF 
ADDITIONAL INTENSIFICATION IS FORECAST THROUGH 24, PEAKING AT 105 
KNOTS, AS THE SYSTEM PASSES OVER VERY WARM WATER IN THE GULF OF 
CARPENTARIA WITH LOW TO MODERATE VWS AND MODERATE SUPPORTING UPPER-
LEVEL OUTFLOW. AFTER TAU 36, WEAKENING IS EXPECTED AS THE UPPER-
LEVEL FLOW PATTERN BECOMES LESS FAVORABLE. THE WEAKENING TREND WILL 
ACCELERATE THROUGH TAU 72, AS THE SYSTEM BECOMES QUASI-STATIONARY IN 
THE SOUTHEASTERN GULF OF CARPENTARIA AS DRY AIR ENTRAINMENT, LAND 
INTERACTION AND INCREASING CONVERGENCE ALOFT WILL COMBINE TO RAPIDLY 
WEAKEN THE SYSTEM. TC 16P WILL DISSIPATE OVER LAND BY TAU 120. 
AVAILABLE MODEL GUIDANCE IS IN GOOD AGREEMENT THOUGH TAU 24, BUT 
SHOWS SIGNIFICANT UNCERTAINTY THEREAFTER. NEARLY ALL MODELS INDICATE 
A PERIOD OF SLOW MOVEMENT AROUND TAU 72 FOLLOWED BY ACCELERATION 
TOWARDS THE WEST, THE UNCERTAINTY BEING IN THE TIMING AND SPEED OF 
MOTION. HOWEVER, THE AFUM AND EGRR MODELS CONTINUE TO INDICATE AN 
EASTWARD TRACK THROUGH THE ENTIRE FORECAST, MOVING THE SYSTEM INTO 
THE CORAL SEA BY TAU 72. THE LARGE AMOUNT OF UNCERTAINTY IN THE 
MODELS LENDS LOW CONFIDENCE IN THE JTWC FORECAST TRACK.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 231800Z IS 34 FEET. NEXT

REMARKS:
TROPICAL CYCLONE (TC) 16P (NORA), LOCATED APPROXIMATELY 419 NM 
NORTHWEST OF CAIRNS, AUSTRALIA, HAS TRACKED SOUTHEASTWARD AT 10 
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL IMAGERY (MSI) 
SHOWS THAT THE CONVECTIVE SIGNATURE ASSOCIATED WITH TC NORA WEAKENED 
THROUGH THE 0000Z HOUR, WITH ONLY A VERY WEAK, RAGGED EYE FEATURE 
EVIDENT IN THE MSI. THE INITIAL POSITION IS PLACED WITH HIGH 
CONFIDENCE BASED ON ANALYSIS OF THE MSI, AND RADAR FIX DATA FROM THE 
WEIPA RADAR SITE. A 232207Z AMSU-B 89 GHZ MICROWAVE IMAGE CONFIRMED 
THAT DEEP CONVECTION WAS LIMITED AT THAT TIME TO THE NORTHWEST 
QUADRANT, WITH THE EYEWALL BEING OPEN TOWARDS THE SOUTHEAST. THE 
INITIAL INTENSITY HAS BEEN LOWERED TO 90 KNOTS FOR THIS WARNING, 
BASED ON SUBJECTIVE DVORAK CURRENT INTENSITY ESTIMATES RANGING FROM 
T4.5 (77 KNOTS) TO T5.0 (90 KNOTS) AND 
AUTOMATED INTENSITY GUIDANCE OF T4.8 (84 KNOTS), HEDGED SLIGHTLY 
HIGHER DUE TO AN INCREASING TREND EVIDENT AT THE TIME OF THE FIX. TC 
16P CONTINUES TRACKING SOUTHEASTWARD OVER THE PAST SIX HOURS ALONG 
THE WESTERN PERIPHERY OF A NEAR EQUATORIAL RIDGE (NER) CENTERED OVER 
EASTERN NEW GUINEA, THOUGH THE TRACK IS SOMEWHAT FLATTER THAN 
ORIGINAL FORECAST, WITH A STRONGER EASTWARD COMPONENT THROUGH THE 
00Z HOUR. AS PREVIOUSLY MENTIONED INTENSITY HAS DECREASED SLIGHTLY 
BUT IS ON AN INCREASING TREND. TC 16P IS FORECAST TO CONTINUE 
TRACKING SOUTHEASTWARD THEN SOUTHWARD UNDER THE STEERING INFLUENCE 
OF THE NER OVER THE NEXT 36 HOURS. AFTER TAU 36, TC NORA IS EXPECTED 
TO SLOW SIGNIFICANTLY AS IT ENTERS A WEAK STEERING ENVIRONMENT 
ASSOCIATED WITH AN UPPER-LEVEL COL AREA BETWEEN THE NER, A 
DEVELOPING STR TO THE WEST-SOUTHWEST AND THE EQUATORWARD END OF A 
MID-LATITUDE TROF TO THE SOUTH, BECOMING NEARLY QUASI-STATIONARY IN 
THE SOUTHEAST CORNER OF THE GULF OF CARPENTARIA THROUGH TAU 72. IN 
THE EXTENDED TAUS, TC 16P WILL ACCELERATE WESTWARD AS THE STR 
BECOMES THE PRIMARY STEERING MECHANISM THROUGH THE REMAINDER OF THE 
FORECAST. WHILE INITIAL INTENSITY HAS DECREASED, BY THE 00Z HOUR, 
INDICATIONS OF STRENGTHENING WERE ALREADY BECOMING EVIDENT, AND SO A 
SHORT PERIOD OF ADDITIONAL INTENSIFICATION IS FORECAST THROUGH TAU 
12, PEAKING AT 95 KNOTS, AS THE SYSTEM PASSES OVER VERY WARM WATER 
WITH LOW TO MODERATE VWS AND IMPROVED UPPER-LEVEL OUTFLOW. AFTER TAU 
12 AND THROUGH TAU 36 SLOW AND STEADY WEAKENING IS EXPECTED AS THE 
UPPER-LEVEL FLOW PATTERN BECOMES LESS FAVORABLE AND THE SYSTEM 
INTERACTS WITH LAND. AFTER TAU 36, AS LAND INTERACTION AND 
CONVERGENCE ALOFT COMBINE, TC 16P WILL EXPERIENCE MORE RAPID 
WEAKENING. THE SYSTEM IS FORECAST TO MAKE LANDFALL IN THE SOUTH GULF 
OF CARPENTARIA BEFORE TAU 96 AND WILL RAPIDLY DISSIPATE OVER LAND BY 
TAU 120. AVAILABLE MODEL GUIDANCE IS BECOMING INCREASINGLY 
UNCERTAIN, WITH THREE POTENTIAL SCENARIOS. THE AFUM AND EGRR MODELS 
CONTINUE TO SHOW THE SYSTEM TRACKING EASTWARD INTO THE CORAL SEA, 
WHILE THE ECMWF AND ENSEMBLE TRACKING THE SYSTEM FURTHER WEST AND 
NORTH, MAKING LANDFALL IN THE WESTERN GULF. THE REMAINDER OF THE 
CONSENSUS MEMBERS ARE GENERALLY IN AGREEMENT WITH THE JTWC FORECAST, 
WHICH LIES WEST OF THE MULTI-MODEL CONSENSUS TRACK. DUE TO THE LARGE 
AMOUNT OF UNCERTAINTY IN THE MODELS, THERE IS LOW CONFIDENCE IN THE 
JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 240000Z IS 
28 FEET. NEXT WARNINGS AT 240900Z, 241500Z, 242100Z AND 250300Z.//

REMARKS:
242100Z POSITION NEAR 15.8S 141.8E.
TROPICAL CYCLONE 16P (NORA), LOCATED APPROXIMATELY 245 NM WEST-
NORTHWEST OF CAIRNS, AUSTRALIA, HAS TRACKED SOUTH-SOUTHEASTWARD
AT 13 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY DEPICTS THE SYSTEM IS WEAKENING DUE TO EXTENSIVE 
INTERACTION WITH THE CAPE YORK PENINSULA. THE INITIAL POSITION IS 
PLACED WITH HIGH CONFIDENCE BASED ON A CIRCULATION FEATURE EVIDENT 
IN THE COMPOSITE RADAR LOOP FROM THE AUSTRALIAN BUREAU OF 
METEOROLOGY. THE INITIAL INTENSITY OF 65 KNOTS IS BASED ON THE 
WEAKENING NATURE OF THE SYSTEM AND IS ABOVE AREA OBSERVATIONS THAT 
ARE DISPLACED FROM THE CIRCULATION CENTER AND TERRAIN INHIBITED. 
UPPER LEVEL ANALYSIS INDICATES THE SYSTEM HAS STRONG POLEWARD 
OUTFLOW CHANNEL. ENVIRONMENTAL ANALYSIS SHOWS THAT SYSTEM IS IN AN 
AREA OF MODERATE (15-20 KNOT) VERTICAL WIND SHEAR AND IS CURRENTLY 
TRACKING OVER LAND. TC NORA WILL CONTINUE TO TRACK SOUTHERLY AS A 
STR ANCHORED OVER WESTERN CENTRAL AUSTRALIA WILL BUILD AND COMPETE 
FOR STEERING, CAUSING THE SYSTEM TO BECOME QUASI-STATIONARY. LAND 
INTERACTION AND INCREASING VERTICAL WIND SHEAR WILL RAPIDLY WEAKEN 
TC 16P WITH DISSIPATION BY TAU 48, SOUTH OF KOWANYAMA. AVAILABLE 
DYNAMIC MODEL GUIDANCE IS IN GENERALLY GOOD AGREEMENT WITH THE 
OVERALL TRACK DIRECTION HOWEVER THERE IS A SUBSTANTIAL SPREAD AFTER 
TAU 24. IN VIEW OF THIS AND THE UNCERTAINTY OF A QUASI-STATIONARY 
MOTION, THERE IS OVERALL LOW CONFIDENCE IN THE JTWC TRACK FORECAST. 
NEXT WARNINGS AT 250300Z, 250900Z, 251500Z AND 252100Z. REFER TO 
TROPICAL CYCLONE 17P (SEVENTEEN) WARNINGS (WTPS32 PGTW) FOR SIX-
HOURLY UPDATES.//

REMARKS:
250300Z POSITION NEAR 17.0S 142.1E.
TROPICAL CYCLONE 16P (NORA), LOCATED APPROXIMATELY 213 NM WEST OF
CAIRNS, AUSTRALIA, HAS TRACKED SOUTHWARD AT 13 KNOTS OVER THE
PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS 
FRAGMENTED AND DISORGANIZED CONVECTION PARTIALLY OBSCURING THE LOW 
LEVEL CIRCULATION CENTER NOW OVER LAND, CAPE YORK, AUSTRALIA. THE 
INITIAL POSITION IS SUPPORTED BY SATELLITE FIXES AND LOCAL SURFACE 
OBSERVATIONS. THE INITIAL INTENSITY IS ASSESSED AT 50 KNOTS WHICH IS 
SCALED LOWER FROM PREVIOUS ESTIMATES BASED ON LAND INTERACTION, AND 
SUPPORTED BY OBSERVATIONS FROM KOWANYAMA, AUSTRALIA REPORTING 
MAXIMUM WINDS OF 30 KNOTS OVER THE LAST SIX HOURS SHIFTING FROM THE 
NORTHEAST TO THE NORTHWEST AND A MINIMUM MSLP OF 984 MB. TC 16P HAS 
TRACKED SOUTH-SOUTHEASTWARD ALONG A WEAK MID-LEVEL RIDGE TO THE 
EAST. TC 16P IS FORECAST TO WEAKEN SIGNIFICANTLY OVER THE NEXT 12 
HOURS WHILE OVER LAND REMAINING NEARLY QUASI-STATIONARY AS ANOTHER 
COMPETING RIDGE TO THE SOUTHWEST BEGINS TO BUILD. THE REMNANTS OF TC 
16P IS EXPECTED TO LINGER AS A POST TROPICAL LOW OVER THE NEXT 48 
HOURS EVENTUALLY TRACKING WESTWARD AS THE SOUTHERN RIDGE BUILDS. 
THERE EXISTS A POSSIBILITY FOR THE REMNANTS OF 16P TO AGAIN TRACK 
OVER THE SOUTHERN PORTION OF THE GULF OF CARPENTARIA BEYOND TAU 48, 
BUT OPPORTUNITY FOR REGENERATION WILL BE SHORT-LIVED. THIS IS THE 
FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL 
HARBOR HI. THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF 
REGENERATION. REFER TO TROPICAL CYCLONE 17P (IRIS) WARNINGS (WTPS32 
PGTW) FOR SIX-HOURLY UPDATES.//
