REMARKS:
070300Z0 POSITION 14.2S7 071.4E2.
ANIMATED INFRARED SATELLITE IMAGERY INDICATES THE AREA OF
CONVECTION LOCATED TO THE SOUTHWEST OF DIEGO GARCIA HAS
BECOME SIGNIFICANTLY MORE ORGANIZED OVER THE PAST 20 HOURS AND
IS NOW CONSIDERED A SIGNIFICANT TROPICAL CYCLONE. THE
WARNING POSITION AND INTENSITY ESTIMATES ARE BASED ON
062300Z1 INFRARED SATELLITE IMAGERY RECEIVED FROM AIR FORCE
GLOBAL WEATHER CENTRAL. ANIMATED WATER VAPOR IMAGERY INDICATES
GOOD OUTFLOW ALOFT. TROPICAL CYCLONE 32S IS LOCATED APPROXIMATELY
300 NM WEST OF TROPICAL CYCLONE 33S (PREVIOUSLY THE TOPIC OF A
TROPICAL CYCLONE FORMATION ALERT). THE CLOSE PROXIMITY OF THESE
TWO SYSTEMS IS CONTRIBUTING TO THE SOUTH-SOUTHEASTERLY MOVEMENT
OF TC 32S. THE SYSTEM IS FORECAST TO CONTINUE SLOWLY TOWARDS THE
SOUTH-SOUTHEAST 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 071351Z7) AND 080300Z1 (DTG 080151Z5). THIS WARNING
SUPERSEDES AND CANCELS NAVPACMETOCCEN WEST GU 060551Z APR 98
TROPICAL CYCLONE FORMATION ALERT (WTXS21 PGTW 060700). REFER TO
TROPICAL CYCLONE 33S WARNINGS (WTXS32 PGTW) FOR TWELVE-HOURLY
