REMARKS:
300300Z6 POSITION  9.4S3   76.8E1.
TROPICAL CYCLONE 02S HAS TRACKED WESTWARD AT 5 KNOTS FOR THE PAST
6 HOURS. THE WARNING POSITION AND INTENSITY ARE BASED ON 300000Z3
INFRARED SATELLITE ANALYSIS. SATELLITE IMAGERY INDICATES THE LOW-
LEVEL CIRCULATION IS 155NM NORTHEAST OF THE CONVECTION. THE STEERING
FLOW IS WESTWARD AS THE SYSTEM REMAINS BETWEEN THE MONSOON TROUGH TO
THE NORTH AND THE SUB-TROPICAL RIDGE TO ITS SOUTH. TC 02S IS
FORECAST TO CONTINUE ITS WESTWARD TRACK, WEAKENING DUE TO INCREASED
VERTICAL WIND SHEAR UNTIL IT DISSIPATES AS A SIGNIFICANT TROPICAL
CYCLONE BY THE END OF THE 24-HOUR PERIOD. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 300000Z3 IS 10 FEET. REFER TO WWIO30 PGFW FOR ADDITIONAL
SEA HEIGHT INFORMATION. NEXT WARNINGS AT 300900Z2 (DTG 300753Z8),
301500Z9 (DTG 301353Z5) AND 302100Z6 (DTG 301953Z1).//
