REMARKS:
070300Z0 POSITION 16.8S5 075.7E9.
ANIMATED INFRARED SATELLITE IMAGERY INDICATES THE AREA OF
CONVECTION LOCATED TO THE SOUTHEAST OF DIEGO GARCIA HAS
BECOME CONSIDERABLY MORE ORGANIZED OVER THE PAST 6 HOURS
AND IS NOW CONSIDERED A SIGNIFICANT TROPICAL CYCLONE.
THE WARNING POSITION AND INTENSITY ESTIMATE ARE BASED
ON 062332Z6 INFRARED SATELLITE IMAGERY FROM AIR FORCE
GLOBAL WEATHER CENTRAL. ANIMATED WATER VAPOR IMAGERY
SHOWS UPPER-LEVEL OUTFLOW IS GOOD WITH ONLY SLIGHT
WIND SHEAR FROM THE WEST. THIS SHEAR IS DUE TO TROPICAL
CYCLONE 32S WHICH IS LOCATED APPROXIMATELY 300NM TO THE
WEST. TROPICAL CYCLONE 33S IS FORECAST TO TRACK SLOWLY TOWARDS
THE WEST AND INTENSIFY THROUGHOUT THE FORECAST PERIOD.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 070000Z7 IS 13 FEET. REFER TO
WWIO30 PGFW FOR ADDITIONAL SEA HEIGHT INFORMATION. NEXT
WARNINGS AT 071500Z3 (DTG 071353Z7) AND 080300Z1 (DTG 080153Z5).
