RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
A 200 NM RADIUS OF 15.8S4 110.8E0 WITHIN THE NEXT 06 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 20 TO 30 KNOTS. METSAT IMAGERY AT 112330Z0 INDICATES THAT A
CIRCULATION CENTER IS LOCATED NEAR 15.9S5 110.8E0. THE SYSTEM IS
QUASI-STATIONARY.
2. REMARKS:
A TROPICAL DISTURBANCE HAS PERSISTED IN THE SOUTHERN INDIAN OCEAN,
410 NM NORTH-NORTHWEST OF LEARMONTH. ANIMATED SATELLITE IMAGERY AND
RECENT MICROWAVE IMAGERY INDICATE A PARTIALLY EXPOSED LOW LEVEL
CIRCULATION CENTER (LLCC) WITH MOST OF THE CONVECTION WEST OF THE
LLCC. UW-CIMSS ANALYSIS PRODUCT DEPICTS THE SYSTEM IS SLIGHTLY
EQUATORWARD OF THE UPPER LEVEL RIDGE AXIS IN A WEAK VERTICAL WIND
SHEAR ENVIRONMENT. ADDITIONALLY, A RECENT QUIKSCAT PASS CLEARLY
DEPICTS A 20 KNOT LLCC. THE MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
NEAR 997 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS GOOD.

PAST SIX HOURS. WARNING POSITION IS BASED ON 120530Z1 VISIBLE AND 
INFRARED SATELLITE ANIMATION. WARNING INTENSITY IS BASED ON 
INTENSITY ESTIMATES OF 30 KTS. ANIMATED SATELLITE IMAGERY INDICATES 
INCREASED ORGANIZATION OF A CONVECTION OVER A LOW LEVEL CIRCULATION 
CENTER EMBEDDED IN THE MONSOON TROUGH. A RECENT QUICKSCATT PASS 
INDICATED A WELL DEFINED LLCC AS WELL. UW-CIMSS SATELLITE DERIVED 
WIND PRODUCTS INDICATE THE SYSTEM IS IN A WEAK VERTICAL WIND SHEAR 
ENVIRONMENT. THE SYSTEM IS FORECAST TO TRACK WESTWARD UNDER THE 
STEERING INFLUENCE OF THE STRONG WESTERLY MONSOONAL FLOW TO THE 
NORTH OF THE SYSTEM, THROUGH THE NEXT 24 HOURS. INCREASING 
INTERACTION WITH THE REMNANTS OF TC 08P WILL SERVE TO TRACK THE 
SYSTEM INCREASINGLY SOUTHWARD THROUGH THE 48 HOUR PERIOD. THE SYSTEM 
IS FORECAST TO INTENSIFY AT A CLIMATOLOGICAL RATE THROUGH THE

REMARKS:
122100Z6 POSITION NEAR 15.0S6 113.0E5.
TC 09S (VINCENT), LOCATED APPROXIMATELY 450 NM NORTH-NORTHWEST OF 
LEARMONTH, AUSTRALIA, HAS TRACKED EAST AT 06 KTS OVER THE PAST SIX 
HOURS. WARNING POSITION IS BASED ON 121730Z4 INFRARED SATELLITE 
IMAGERY. WARNING INTENSITY IS BASED ON CURRENT INTENSITY ESTIMATES 
OF 35 TO 45 KTS. A 121422Z2 SPECIAL SENSOR MICROWAVE IMAGER PASS 
REVEALED A PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) 
EAST OF THE DEEP CONVECTION. THE 200 MB ANALYSIS SHOWS THAT TC 09S 
IS DEVELOPING A WEAK ANTICYCLONE ALOFT. HOWEVER, ANIMATED WATER 
VAPOR INDICATES RESTRICTED OUTFLOW SOUTH WITH GOOD OUTFLOW OVER THE 
NORTHERN SEMICIRCLE. TC 09S IS FORECAST TO TRACK EASTWARD TO EAST-
SOUTHEASTWARD UNDER THE STEERING INFLUENCE OF STRONG EQUATORIAL 
WESTERLIES TO THE NORTH AND WITHIN THE MONSOON TROUGH THROUGH THE 
FORECAST PERIOD. THE SYSTEM IS FORECAST TO INTENSIFY SLOWLY IN THE 
FIRST 24 HOURS, BUT SHOULD INTENSIFY AT A CLIMATOLOGICAL RATE LATE 
IN THE PERIOD AS IT TRACKS UNDER THE BUILDING UPPER-LEVEL RIDGE. 
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 121800Z2 IS 10 FEET. NEXT

REMARKS:
142100Z8 POSITION NEAR 16.9S6 120.2E5.
TC 09S (VINCENT), LOCATED APPROXIMATELY 230 NM NORTH-NORTHEAST OF
PORT HEDLAND, AUSTRALIA, HAS TRACKED EAST-SOUTHEASTWARD AT 06 KTS
OVER THE PAST SIX HOURS. WARNING POSITION IS BASED ON 141730Z6
ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON CURRENT INTENSITY ESTIMATES OF 30 KTS AND SYNOPTIC REPORTS OF 25
KNOTS. MULTI-SPECTRAL ANIMATION DEPICTS A PARTIALLY-EXPOSED LOW-
LEVEL CIRCULATION CENTER (LLCC) WITH  CONVECTION SHEARED 7 NM TO THE
WEST OF THE CENTER. TC 09S IS FORECAST TO TRACK SOUTHEASTWARD,
WITHIN A MONSOON TROUGH, UNDER THE STEERING INFLUENCE OF STRONG
EQUATORIAL WESTERLIES THROUGH THE NEXT 12 HOURS. THEN, TC 09S SHOULD
BEGIN TO TRACK SOUTHEASTWARD TO SOUTHWARD UNDER THE STEERING
INFLUENCE OF THE MID-LEVEL RIDGE TO THE SOUTHEAST. TC 09S SHOULD
GRADUALLY INTENSIFY DURING THE NEXT 36 HOURS AS THE UPPER LEVEL
RIDGE TEMPORARILY BUILDS BACK OVER THE SYSTEM. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 141800Z4 IS 14 FEET. NEXT WARNINGS AT 150900Z5 (DTG
150751Z9) AND 152100Z9 (DTG 151951Z2).//

REMARKS:
150900Z5 POSITION NEAR 17.5S3 119.5E6.
TC 09S (VINCENT), LOCATED APPROXIMATELY 190 NM NORTH-NORTHEAST OF
PORT HEDLAND, AUSTRALIA, HAS TRACKED SOUTHWARD AT 05 KTS OVER THE
PAST SIX HOURS. WARNING POSITION IS BASED ON 150530Z4 VISIBLE AND
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
CURRENT INTENSITY ESTIMATES OF 30 KTS AND SYNOPTIC REPORTS OF 25
KNOTS. ANIMATED SATELLITE IMAGERY INDICATES CONVECTION REDEVELOPING
OVER THE LOW LEVEL CIRCULATION CENTER (LLCC). TC 09S IS FORECAST TO
TRACK SOUTH-SOUTHWARD, UNDER THE STEERING INFLUENCE OF THE
SUBTROPICAL RIDGE TO THE EAST-SOUTHEAST. AN APPROACHING MID-LATITUDE
TROUGH WILL SERVE TO FURTHER ENHANCE THE SOUTHWARD MOVEMENT. TC 09S
SHOULD INTENSIFY AS IT APPROACHES LAND FALL, MAKE LANDFALL AT
APPROXIMATELY 161800Z6 NEAR PORT HEADLAND, THEN BEGIN DISSIPATING
OVER LAND. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 150600Z2 IS 14 FEET.
NEXT WARNINGS AT 152100Z9 (DTG 151951Z2) AND 160900Z6 (DTG

REMARKS:
152100Z9 POSITION NEAR 19.9S9 122.4E9.
TROPICAL CYCLONE (TC) 09S (VINCENT), LOCATED APPROXIMATELY 200 NM
EAST OF PORT HEDLAND, AUSTRALIA, WAS RELOCATED FURTHER SOUTH THAN
PREVIOUSLY ANALYZED, AND HAS MOVED OVER LAND. THE WARNING POSITION
IS BASED ON 151800Z5 SYNOPTIC DATA, 151730Z7 INFRARED SATELLITE
IMAGERY, AND RADAR. THE WARNING INTENSITY IS BASED ON CURRENT
INTENSITY ESTIMATES OF 30 KTS AND SYNOPTIC REPORTS OF 25 KNOTS. TC
09S IS FORECAST TO CONTINUE TO TRACK SOUTHWARD UNDER THE STEERING
INFLUENCE OF THE SUBTROPICAL RIDGE TO THE EAST-SOUTHEAST. AN
APPROACHING MID-LATITUDE TROUGH WILL SERVE TO FURTHER ENHANCE THE
SOUTHWARD MOVEMENT. TC 09S WILL CONTINUE TO WEAKEN OVER LAND AND
COMPLETELY DISSIPATE BY THE 12 HOUR FORECAST PERIOD. THIS IS THE
FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WARNING CENTER
(NAVPACMETOCCEN).  THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF
REGENERATION.//
