REMARKS:
180300Z2 POSITION NEAR 21.6N9 128.0E1.
TROPICAL DEPRESSION (TD) 16W (CHOI-WAN), LOCATED APPROXIMATELY 295 NM
SOUTH OF NAHA, OKINAWA, HAS TRACKED NORTHWESTWARD AT 10 KNOTS
OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED ON
172330Z6 MULTISPECTRAL SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED SATELLITE CURRENT INTENSITY ESTIMATES OF 30 AND 35 KNOTS.
THE LOCATION OF THE LOW LEVEL CIRCULATION CENTER EMBEDDED
IN THE REVERSE ORIENTED MONSOON TROUGH CONTINUES TO BE UNCERTAIN.
SATELLITE FIXES JUSTIFY THE CURRENT POSITION WHILE A RECENT
172122Z5 QUIKSCAT PASS SUGGESTS THAT THE POSITION MAY ACTUALLY
BE FURTHER WEST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 180000Z9
IS 12 FEET. REFER TO WWPW30 RJTX FOR ADDITIONAL SEA HEIGHT
