REMARKS:
281500Z6 POSITION NEAR 24.9N5 121.7E1.
TROPICAL STORM (TS) 23W (LEKIMA), LOCATED APPROXIMATELY 20 NM 
SOUTHEAST OF TAIPEI, TAIWAN, HAS TRACKED NORTHWARD AT 03 KNOTS. THE 
WARNING POSITION IS BASED ON 281130Z5 INFRARED SATELLITE IMAGERY, 
SYNOPTIC DATA, AND RADAR DATA. THE WARNING INTENSITY IS BASED ON 
SATELLITE CURRENT INTENSITY ESTIMATES OF 25 KNOTS AND SYNOPTIC 
REPORTS NEAR 35 KNOTS. ANIMATED INFRARED SATELLITE IMAGERY DEPICTS 
DECREASING ORGANIZATION AND WEAKENING DEEP CONVECTION OVER THE PAST 
6 HOURS. HOWEVER, 281200Z3 SYNOPTIC ANALYSIS AND RADAR DATA DEPICT 
TWO 30-35 KNOT LOW-LEVEL CIRCULATION CENTERS (LLCC). IN ADDITION TO 
THE STORM CENTER, THERE IS AN APPARENT LLCC NEAR 23.0N5 120.6E9, 
OVER SOUTHERN TAIWAN. SEA LEVEL PRESSURE ANALYSIS SHOWS A BROAD 
AREA OF NEAR 1000.0 MB PRESSURES ACROSS TAIWAN. RADAR SHOWS A BROAD 
AREA OF CONVECTION WITH THE NORTHERN LLCC, AND ISOLATED CONVECTION 
WITH THE SOUTHERN LLCC. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 281200Z3 
IS 14 FEET. REFER TO WWPW31 RJTX FOR ADDITIONAL SEA HEIGHT 
INFORMATION. NEXT WARNINGS AT 282100Z3, 290300Z4, 290900Z0 AND 
291500Z7.//
