REMARKS:
051500Z1 POSITION NEAR 12.6S9 95.8E2.
TROPICAL CYCLONE 17S (WALTER), LOCATED APPROXIMATELY 50 NM WEST OF
COCOS ISLAND, HAS TRACKED SOUTHWESTWARD AT 8 KNOTS OVER THE PAST 6
HOURS. THE WARNING POSITION IS BASED ON 051130Z0 INFRARED SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 77 AND 90 KNOTS. ENHANCED INFRARED ANIMATION
INDICATES SOME WEAKENING DURING THE PAST 12 HOURS AND THE LOW-LEVEL
CIRCULATION CENTER HAS BECOME MORE DIFFICULT TO LOCATE. THE SYSTEM
IS LOCATED JUST NORTH OF THE UPPER-LEVEL RIDGE AXIS IN A REGION OF
SLIGHTLY HIGHER VERTICAL WIND SHEAR, ACCOUNTING FOR THE WEAKENING
TREND. AT 051200Z8, COCOS ISLAND INTERNATIONAL AIRPORT REPORTED
SUSTAINED WINDS FROM THE NORTHEAST AT 33 KNOTS. TROPICAL CYCLONE 17S
IS EXPECTED TO TRACK SOUTHWESTWARD DURING THE FORECAST PERIOD. TC
17S SHOULD SLOWLY WEAKEN AS IT TRACKS UNDER VERTICAL SHEAR NORTH OF
THE SUBTROPICAL RIDGE AXIS. THE SYSTEM COULD EXPERIENCE
INTENSIFICATION NEAR THE END OF THE FORECAST PERIOD, IF IT TRACKS
BELOW THE RIDGE AXIS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 051200Z8 IS
20 FEET. NEXT WARNINGS AT 060300Z9 AND 061500Z2. REFER TO TROPICAL
CYCLONE 16S WARNINGS (WTXS31 PGTW) FOR TWELVE-HOURLY UPDATES. REFER
TO TROPICAL CYCLONE 18S (EVARISTE) WARNINGS (WTXS33 PGTW) FOR
TWELVE-HOURLY UPDATES.//
