REMARKS:
291500Z7 POSITION 19.9S9  108.5E4
TROPICAL CYCLONE 15S (TIFFANY) HAS BEEN TRACKING WESTWARD AT
05 KNOTS FOR THE PAST 06 HOURS. THE WARNING POSITION IS BASED
UPON 291130Z6 ENHANCED INFRARED SATELLITE IMAGERY. THE SYSTEM
HAS WEAKENED RAPIDLY OVER THE PAST 12 HOURS DUE TO STRONG
VERTICAL WIND SHEAR AND COOL SEA SURFACE TEMPERATURES. TROPICAL
CYCLONE 15S (TIFFANY) SHOULD TRACK WEST-SOUTHWESTWARD DURING THE
FORECAST PERIOD DUE TO A WEAKNESS DEVELOPING IN THE SURFACE
RIDGING TO ITS SOUTH. HOWEVER, THE SYSTEM WILL CONTINUE WEAKENING
RAPIDLY DUE TO VERTICAL WIND SHEAR AND COOL SEA SURFACE
TEMPERATURES. THE SYSTEM IS EXPECTED TO DISSIPATE OVER THE WATER
BY THE 36 HOUR POSITION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
291200 IS 17 FEET. NEXT WARNINGS AT 300300Z6 (DTG 300151Z0) AND
301500Z9 (DTG 301351Z3). REFER TO TROPICAL CYCLONE  14P (LES)
