TROPICAL CYCLONE 31S (FREDERIC-EVRINA) HAS TRACKED WEST-SOUTHWESTWARD
AT 11 KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION AND
INTENSITY ARE BASED UPON 062330Z4 ANIMATED INFRARED SATELLITE IMAGERY
WITH CURRENT INTENSITY ESTIMATES OF 30 KNOTS. SATELLITE ANALYSIS
INDICATES THE LOW LEVEL CIRCULATION IS BEGINNING TO ELONGATE AS TC
31S CONTINUES TO WEAKEN VERY SLOWLY AS IT TRACKS WESTWARD UNDER THE
STEERING INFLUENCE OF THE SUBTROPICAL RIDGE TO ITS SOUTH. TROPICAL
CYCLONE 31S IS FORECAST TO DISSIPATE OVER WATER WITHIN 24 HOURS.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 070000Z IS 10 FEET. THIS IS THE
FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WARNING CENTER
(NAVPACMETOCCEN PEARL HARBOR HI). THE SYSTEM WILL BE CLOSELY
MONITORED FOR SIGNS OF REGENERATION. REFER TO TROPICAL CYCLONE  32S
(GWENDA) WARNINGS (WTXS32 PGTW) FOR SIX-HOURLY UPDATES.//
