REMARKS:
070900Z6 POSITION NEAR 19.0S0 117.6E5. TROPICAL CYCLONE (TC) 32S
(GWENDA) HAS TRACKED SOUTH-SOUTHEASTWARD OFF THE NORTHWEST COAST OF
AUSTRALIA AT 13 KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION
AND INTENSITY ARE BASED UPON 070530Z5 ANIMATED VISIBLE AND INFRARED
SATELLITE IMAGERY WITH INTENSITY ESTIMATES OF 90 AND 115 KNOTS.
SATELLITE IMAGERY INDICATES THE VERTICAL WIND SHEAR CONTINUES TO
WEAKEN THE SYSTEM AS IT MOVES CLOSER TO SHORE. MOST OF THE
CONVECTION IS BEING ADVECTED OFF TO THE SOUTHEAST. THE STRONG
VERTICAL WIND SHEAR AND LAND FALL IN THE NEXT 12 HOURS WILL WEAKEN
GWENDA RAPIDLY THROUGH THE FORECAST PERIOD. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 070600Z3 IS 25 FEET. NEXT WARNINGS AT 071500Z3
(DTG 071353Z9), 072100Z0 (DTG 071953Z5) AND 080300Z1 (DTG 080153Z7).
