REMARKS:
090900Z8 POSITION NEAR 15.7S3   72.3E2.
TROPICAL CYCLONE (TC) 05S, LOCATED APPROXIMATELY 500 NM SOUTH OF
DIEGO GARCIA OVER THE SOUTH INDIAN OCEAN, HAS TRACKED WESTWARD AT 03
KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
090530Z7 VISIBLE AND INFRARED SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 77
AND 90 KNOTS. ANIMATED INFRARED SATELLITE IMAGERY DEPICTS STRONG
CONVECTION TO THE EAST OF THE SYSTEM AND A 10 NM RAGGED EYE. A
RECENT MICROWAVE IMAGE ALSO SHOWS THIN BANDS WRAPPING INTO THE
EYEWALL. UW-CIMSS VERTICAL WIND SHEAR PRODUCT INDICATES WEAK
VERTICAL WIND SHEAR CURRENTLY OVER THE SYSTEM, HOWEVER, INCREASING
VERTICAL WIND SHEAR IS EVIDENT SOUTH OF THE SYSTEM. A MID- TO UPPER-
LEVEL RIDGE HAS WEAKENED THE SUB-TROPICAL RIDGE, AND THE SYSTEM
CONTINUES TO DRIFT IN WEAK STEERING FLOW.  THE SYSTEM IS FORECAST TO
INTENSIFY SLOWLY AS IT TRACKS UNDER INCREASING VERTICAL WIND SHEAR
THROUGH THE PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 090600Z5 IS
22 FEET. NEXT WARNINGS AT 092100Z2 (DTG 091951Z5) AND 100900Z0 (DTG
100751Z4). REFER TO TROPICAL CYCLONE  04S (ANDO) WARNINGS (WTXS31
PGTW) FOR TWELVE-HOURLY UPDATES.//
