REMARKS:
050900Z4 POSITION NEAR 16.9S6 55.5E5.
TROPICAL CYCLONE (TC) 04S (ANDO), LOCATED EAST OF MADAGASCAR IN THE
SOUTH INDIAN OCEAN, HAS TRACKED SOUTH-SOUTHWESTWARD AT 09 KNOTS
DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 050516Z7
INFRARED AND VISIBLE SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 115 KNOTS.
ANIMATED INFRARED SATELLITE IMAGERY CONTINUES TO DEPICT IMPROVED
ORGANIZATION AND A 10 NM EYE. CONVECTION HAS INTENSIFIED SLIGHTLY IN
ALL QUADRANTS. TC 04S CONTINUES TO MOVE INTO A WEAKNESS IN THE
SUBTROPICAL RIDGE, CAUSED BY THE APPROACHING MID-LATITUDE TROUGH.
THE SYSTEM IS FORECAST TO TRACK THROUGH THE WEAKNESS AND BEGIN
RECURVATURE. THE SYSTEM WILL MAINTAIN INTENSITY IN A FAVORABLE
ENVIRONMENT, THEN BEGIN TO WEAKEN UNDER INCREASING VERTICAL WIND
SHEAR TOWARD THE END OF THE FORECAST PERIOD. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 050600Z1 IS 20 FEET. REFER TO WWIO30 RJTX FOR
ADDITIONAL SEA HEIGHT INFORMATION. NEXT WARNINGS AT 052100Z8 (DTG
051952Z2) AND 060900Z5 (DTG 060752Z0).//
