REMARKS:
090900Z8 POSITION NEAR 15.2S8 98.2E9.
TROPICAL CYCLONE (TC) 09S (SALLY), LOCATED APPROXIMATELY 195 NM
SOUTH-SOUTHEAST OF THE COCOS ISLANDS, HAS TRACKED SOUTHWESTWARD
AT 06 KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED
ON 090530Z7 MULTISPECTRAL SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 35 AND 45
KNOTS. RECENT MICROWAVE SATELLITE IMAGERY REVEALS THE SYSTEM IS
BEGINNING TO ENTRAIN DRY AIR CAUSING IT TO SLIGHTLY WEAKEN. TC
09S IS FORECAST TO CONTINUE TRACKING SOUTHWESTWARD ALONG THE
NORTHERN PERIPHERY OF THE MID-LEVEL RIDGE CENTERED TO THE SOUTH-
EAST. THE SYSTEM IS EXPECTED TO REMAIN AT THE CURRENT INTENSITY AND
WEAKEN NEAR THE END OF THE FORECAST PERIOD UNDER MODERATE UPPER
LEVEL CONDITIONS AND THE CONTINUING PRESENCE OF DRIER AIR. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 090600Z5 IS 15 FEET. NEXT WARNINGS AT
092100Z2 AND 100900Z0. JUSTIFICATION FOR CORRECTION: ORIGINAL DTG
SHOULD READ 090752Z JAN 05 RATHER THAN 090751Z JAN 05.//
