REMARKS:
070300Z POSITION NEAR 12.3S 107.6E.
TROPICAL CYCLONE (TC) 18S (JACOB), LOCATED APPROXIMATELY 380 NM
SOUTH OF JAKARTA, INDONESIA, HAS TRACKED WEST-NORTHWESTWARD AT
10 KNOTS OVER THE PAST SIX HOURS. RECENT DVORAK SATELLITE INTEN-
SITY ESTIMATES AND A 062316Z QUIKSCAT PASS INDICATE THAT THIS
SYSTEM HAS INTENSIFIED TO TROPICAL CYCLONE STRENGTH. TC 18S IS
TRACKING ALONG THE WESTWARD EXTENSION OF A SUBTROPICAL STEERING
RIDGE ANCHORED OVER SOUTHWESTERN AUSTRALIA. THIS RIDGE EXTENSION
IS EXPECTED TO WEAKEN DURING THE FORECAST PERIOD IN RESPONSE TO
AN APPROACHING MIDLATITUDE TROUGH CURRENTLY OBSERVED TO THE
SOUTHWEST OF THE SYSTEM. AS THE STEERING RIDGE WEAKENS, STRONG
LOW TO MID-LEVEL WESTERLY FLOW TO THE NORTH OF THE SYSTEM WILL
EXERT A COMPETING STEERING INFLUENCE, AND THE SYSTEM IS EXPECTED
TO SLOW IN THIS COMPETING STEERING ENVIRONMENT. VERTICAL WIND
SHEAR REMAINS MODERATE. HOWEVER, A REORIENTATION OF THE UPPER
LEVEL PATTERN IS EXPECTED TO INDUCE A SLIGHT DECREASE IN VERTICAL
WIND SHEAR, AND THE APPROACHING MIDLATITUDE TROUGH WILL ALLOW
POLEWARD OUTFLOW TO IMPROVE. THEREFORE, THE FORECAST CALLS FOR
SLOW INTENSIFICATION THROUGH TAU 48. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 070000Z IS 11 FEET. NEXT WARNINGS AT 071500Z AND
080300Z. REFER TO TROPICAL CYCLONE  17S (GEORGE) WARNINGS
(WTXS31 PGTW) FOR TWELVE-HOURLY UPDATES.//

REMARKS:
070900Z POSITION NEAR 12.4S 107.1E.
TROPICAL CYCLONE (TC) 18S (JACOB), LOCATED APPROXIMATELY 385 NM
SOUTH OF JAKARTA, INDONESIA, HAS TRACKED WESTWARD AT 08 KNOTS
OVER THE PAST SIX HOURS. TC 18S IS TRACKING ALONG THE WESTWARD
EXTENSION OF A SUBTROPICAL STEERING RIDGE ANCHORED OVER SOUTH-
WESTERN AUSTRALIA. THIS RIDGE EXTENSION IS EXPECTED TO WEAKEN
IN RESPONSE TO AN APPROACHING MIDLATITUDE TROUGH TO THE SOUTH-
WEST OF THE SYSTEM. AS THE STEERING RIDGE WEAKENS, STRONG LOW
TO MID-LEVEL WESTERLY FLOW TO THE NORTH OF THE SYSTEM WILL EXERT
A COMPETING STEERING INFLUENCE. THE SYSTEM WILL SLOW AND BEGIN
TO TURN TO THE NORTH AND THEN TO THE NORTHEAST AS THE MID-LEVEL
WESTERLY FLOW EXERTS MORE OF A STEERING INFLUENCE AND AS THE
SYSTEM INTERACTS WEAKLY WITH TC 17S. UPPER AIR ANALYSIS REVEALS
MODERATE VERTICAL WIND SHEAR AND THIS IS EXPECTED DECREASE ONLY
SLIGHTLY THROUGH THE FORECAST PERIOD. THE APPROACHING MIDLATITUDE
TROUGH WILL INCREASE POLEWARD OUTFLOW AND ALLOW TC 18S TO INTEN-
SIFY AT NEARLY A CLIMATALOGICAL RATE THROUGH TAU 36. AS THE
SYSTEM BECOMES QUASI-STATIONARY BETWEEN TAUS 36 AND 48, UPWELLING
WILL CAUSE A LESS THAN CLIMATOLOGICAL RATE OF INTENSIFICATION.
THE DYNAMIC AIDS ARE IN POOR AGREEMENT AND THE MODEL FIELDS ARE
HAVING DIFFICULTY RESOLVING THE LOW LEVEL ENVIRONMENT FOR THIS
SYSTEM. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 070600Z IS 15 FEET.

TROPICAL CYCLONE (TC) 18S (JACOB), LOCATED APPROXIMATELY 410 NM
SOUTH OF JAKARTA, INDONESIA, HAS TRACKED WESTWARD AT 08 KNOTS
OVER THE PAST SIX HOURS. TC 18S CONTINUES TO TRACK WESTWARD
ALONG THE NORTHERN PERIPHERY OF A SUBTROPICAL RIDGE TO THE SOUTH
OF THE SYSTEM. GENERALLY WESTWARD MOTION IS EXPECTED TO CONTINUE
THROUGH THE FORECAST PERIOD, WITH A GRADUAL SLOWING OF FORWARD
TRACK SPEED IN RESPONSE TO COMPETING WESTERLY FLOW TO THE NORTH
ASSOCIATED WITH NEAR-EQUATORIAL RIDGING. THE TRACK FORECAST RE-
PRESENTS A DEPARTURE FROM THE PREVIOUS FORECAST TO ACCOUNT FOR A
STRONGER SUBTROPICAL STEERING RIDGE TO THE SOUTH THAN PREVIOUSLY
EXPECTED. THE SEPARATION BETWEEN TC 17S AND TC 18S TO THE SOUTH-
EAST IS EXPECTED TO INCREASE, SO DIRECT INTERACTION BETWEEN THE
TWO CYCLONES IS NOT ANTICIPATED. TC 17S IS FORECAST TO INTENSIFY
SLIGHTLY EARLY IN THE FORECAST PERIOD UNDER THE INFLUENCE OF
FAVORABLE POLEWARD OUTFLOW ASSOCIATED WITH MIDLATITUDE TROUGHING
TO THE SOUTH AND MODERATE VERTICAL WIND SHEAR. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 071800Z IS 18 FEET. NEXT WARNINGS AT 080900Z AND

REMARKS:
080900Z POSITION NEAR 12.8S 105.8E.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 080600Z IS 20 FEET.
TROPICAL CYCLONE (TC) 18S (JACOB), LOCATED APPROXIMATELY 405 NM
SOUTH OF JAKARTA, INDONESIA, HAS REMAINED QUASI-STATIONARY OVER
THE PAST SIX HOURS. THE SYSTEM IS CURRENTLY UNDER THE COMPETING
STEERING INFLUENCE OF THE NEAR EQUATORIAL RIDGE (NER) TO ITS NORTH
ANCHORED OVER THE JAVA SEA, AND THE SUBTROPICAL RIDGE (STR) TO ITS
SOUTH ANCHORED OVER SOUTHWESTERN AUSTRALIA. THIS STEERING PATTERN
IS FORECAST TO PERSIST AS THE NER STRENGTHENS AND THE STR IS RE-
INFORCED FROM THE WEST AFTER A MIDLATITUDE TROUGH EXITS THE
AREA. RECENT ANIMATED MULTISPECTRAL IMAGERY REVEALS THE LOW LEVEL
CIRCULATION CENTER IS PARTIALLY EXPOSED, DUE TO MODERATE VERTICAL
WIND SHEAR (VWS) OVER THE SYSTEM. TC 18S WILL INTENSIFY SLIGHTLY
THROUGH THE FORECAST PERIOD AS  VWS IS REDUCED BY A BUILDING
200 MB ANTICYCLONE ALOFT. NEXT WARNINGS AT 082100Z AND 090900Z.

090900Z POSITION NEAR 15.0S 108.5E.
TROPICAL CYCLONE (TC) 18S (JACOB), LOCATED APPROXIMATELY 560 NM
NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTH-SOUTHEASTWARD AT
09 KNOTS OVER THE PAST SIX HOURS. THE NEAR EQUATORIAL RIDGE (NER) AN-
CHORED OVER INDONESIA CONTINUES TO BE THE PRIMARY STEERING INFLUENCE
ON TC 18S. AFTER TAU 24, THE NER WILL BUILD SOUTHWARD OVER THE TIMOR
SEA, CAUSING AN INCREASE IN TRACK SPEED PRIOR TO LANDFALL, WHICH WILL
OCCUR AFTER TAU 48. THE SYSTEM HAS MAINTAINED INTENSITY OVER THE PAST
06 HOURS, AND WILL SLOWLY INTENSIFY AS AN IMPROVING POLWARD OUTFLOW
CHANNEL HELPS THE SYSTEM OVERCOME THE EFFECTS OF MODERATE VERTICAL
WIND SHEAR. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 090600Z IS 20 FEET.

TROPICAL CYCLONE (TC) 18S (JACOB), LOCATED APPROXIMATELY 460 NM
NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTHEASTWARD AT
06 KNOTS OVER THE PAST SIX HOURS. TC 18S CONTINUES TO TRACK SOUTH-
EASTWARD ALONG THE SOUTHWESTERN PERIPHERY OF A NEAR-EQUATORIAL
(NER) RIDGE ANCHORED OVER INDONESIA. THE NER IS FORECAST TO BUILD
SOUTHWARD OVER THE TIMOR SEA TO THE EAST OF TC 18S, ALLOWING THE
STORM TO CONTINUE ALONG A GENERALLY SOUTHEASTWARD TRACK THROUGH
THE FORECAST PERIOD. THE SYSTEM SHOULD BEGIN TO INTENSIFY MORE
RAPIDLY AFTER TAU 12 DUE TO INCREASING POLEWARD OUTFLOW AROUND
THE SOUTHERN PERIPHERY OF THE NEAR-EQUATORIAL RIDGE, INCREASING
EQUATORWARD OUTFLOW ASSOCIATED WITH UPPER LEVEL RIDGING TO THE
WEST OF THE STORM, AND DECREASING VERTICAL WIND SHEAR. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 091800Z IS 24 FEET. NEXT WARNINGS AT
100300Z, 100900Z, 101500Z AND 102100Z.//

TROPICAL CYCLONE (TC) 18S (JACOB), LOCATED APPROXIMATELY 420 NM
NORTH-NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTHEAST-
WARD AT 07 KNOTS OVER THE PAST SIX HOURS. TC 18S IS TRACKING
ALONG THE SOUTHWESTERN PERIPHERY OF A NEAR EQUATORIAL RIDGE (NER)
ANCHORED NORTHEAST OF THE SYSTEM. THIS RIDGE IS FORECAST TO EX-
TEND SOUTHWARD OVER THE TIMOR SEA TO THE EAST OF TC 18S, ALLOWING
THE STORM TO CONTINUE PROGRESSING SOUTHEASTWARD. TC 18S IS FORE-
CAST TO STEADILY INTENSIFY UNDER THE INFLUENCE OF INCREASINGLY
FAVORABLE, WARM SEA SURFACE TEMPERATURES AND GOOD EQUATORWARD
OUTFLOW UNTIL MAKING LANDFALL AFTER TAU 36. HOWEVER, VERTICAL
WIND SHEAR ASSOCIATED WITH UPPER LEVEL SOUTHERLY FLOW ON THE
PERIPHERY OF A SUBTROPICAL RIDGE ANCHORED TO THE SOUTHWEST OF
THE SYSTEM IS EXPECTED TO LIMIT INTENSIFICATION TO A LESS THAN
CLIMATOLOGICAL RATE, PARTICULARLY EARLY IN THE FORECAST PERIOD.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 100000Z IS 25 FEET. NEXT

TROPICAL CYCLONE (TC) 18S (JACOB), LOCATED APPROXIMATELY 150 NM
NORTH-NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTH-SOUTH-
EASTWARD AT 18 KNOTS OVER THE PAST SIX HOURS. TC 18S CONTINUES TO
TRACK RAPIDLY TOWARD THE NORTHWESTERN COAST OF AUSTRALIA ALONG
THE SOUTHWESTERN PERIPHERY OF A NEAR-EQUATORIAL RIDGE ANCHORED
OVER INDONESIA. THIS GENERALLY SOUTHEASTWARD MOTION IS EXPECTED
TO CONTINUE THROUGH THE FORECAST PERIOD, WITH SOME SLOWING IN
FORWARD TRACK SPEED AFTER LANDFALL AROUND TAU 12. THE SYSTEM HAS
REORGANIZED SLIGHTLY OVER THE PAST SIX HOURS, EXHIBITING A MORE
SYMMETRICAL CONVECTIVE SIGNATURE. ALTHOUGH THIS MAY BE INDICATIVE
OF SOME INTENSIFICATION, RECENT MICROWAVE SATELLITE IMAGERY
SUGGESTS THAT THE STORM HAS MAINTAINED INTENSITY OVER THE PAST
SIX HOURS. HOWEVER, SLIGHT INTENSIFICATION IS ANTICIPATED THROUGH
TAU 12 AS THE SYSTEM PASSES OVER VERY WARM WATER OFFSHORE. THE
SYSTEM WILL STEADILY WEAKEN AFTER MAKING LANDFALL AND IS FORECAST
TO DISSIPATE BY TAU 36. NUMERICAL MODELS INDICATE A SLOWER FORWARD
TRACK SPEED AND A LARGER EASTWARD COMPONENT TO STORM TRACK THROUGH
TAU 12. THIS FORECAST IS WEIGHTED TOWARD PERSISTENCE IN THE TAU 00
TO TAU 12 PERIOD, DEPICTING A FASTER FORWARD TRACK SPEED AND A
MORE SOUTHWARD TRACK THAN THE NUMERICAL MODELS SUGGEST. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 101800Z IS 21 FEET. NEXT WARNINGS AT

REMARKS:
110300Z POSITION NEAR 19.6S 114.5E.
TROPICAL CYCLONE (TC) 18S (JACOB), LOCATED APPROXIMATELY 175 NM
NORTH OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTHEASTWARD AT 11
KNOTS OVER THE PAST SIX HOURS. TC 18S CONTINUES TO TRACK SOUTH-
EASTWARD ALONG THE SOUTHWESTERN PERIPHERY OF A NEAR-EQUATORIAL
RIDGE ANCHORED OVER INDONESIA. THIS MOTION IS EXPECTED TO CONT-
INUE THROUGH THE FORECAST PERIOD. RECENT MICROWAVE SATELLITE
IMAGERY, INCLUDING A 11/0035Z SSMIS PASS, REVEALS THAT THE SYS-
TEM IS BEGINNING TO ENTRAIN DRIER AIR FROM THE SOUTHWEST.
ADDITIONALLY, MULTISPECTRAL SATELLITE IMAGERY SUGGESTS A LACK
OF DEEP CONVECTION IN THE NORTHEASTERN QUADRANT OF THE STORM.
HOWEVER, SEA  SURFACE TEMPERATURES REMAIN FAVORABLY WARM AND
THE STORM IS EXPECTED TO MAINTAIN INTENSITY IN THIS ENVIRONMENT
OF COMPETING INFLUENCES. TC 18S WILL DISSIPATE STEADILY AFTER
LANDFALL BETWEEN TAU 12 AND TAU 24. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 110000Z IS 22 FEET. NEXT WARNINGS AT 111500Z AND
120300Z.//

REMARKS:
110900Z POSITION NEAR 19.6S 114.9E.
TROPICAL CYCLONE (TC) 18S (JACOB), LOCATED APPROXIMATELY 170 NM
NORTH OF LEARMONTH, AUSTRALIA, HAS TRACKED EAST-SOUTHEASTWARD AT
06 KNOTS OVER THE PAST SIX HOURS. TC 18S HAS BEEN TRACKING EAST-
SOUTHEASTWARD ALONG THE SOUTHWESTERN PERIPHERY OF A 500 MB NEAR-
EQUATORIAL RIDGE ANCHORED OVER INDONESIA. TC 18S HAS SLOWED AS
IT IS BEGINNING TO BE STEERED AT THE LOWER LEVELS. THIS SLOWER
FORWARD MOTION IS EXPECTED TO CONTINUE THROUGH LANDFALL WHICH WILL
SHORTLY AFTER TAU 12. TC 18S WILL TRACK EAST-SOUTHEASTWARD UNDER
THE INFLUENCE OF THE 700 MB ANTICYCLONE TO THE NORTH-NORTHWEST OF
THE SYSTEM. AN 11/0235Z AMSU-B IMAGE REVEALS THAT THE SYSTEM IS
CONTINUING TO ENTRAIN DRIER AIR FROM THE SOUTHWEST AND THAT MUCH
OF THE DEEP CONVECTION HAS DECREASED. UPPER LEVEL ANALYSIS ALSO
SHOWS THAT VERTICAL WIND SHEAR HAS INCREASED. THESE NEGATIVE FACTORS
HAVE CONTRIBUTED TO SIGNIFICANTLY WEAKEN THE SYSTEM. TC 18S IS
EXPECTED TO CONTINUE WEAKENING THROUGH THE FORECAST PERIOD AND
DISSIPATE OVER LAND BY TAU 36. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
110600Z IS 20 FEET. NEXT WARNINGS AT 112100Z AND 120900Z.//
