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
160751Z0).//
