REMARKS:
071500Z3 POSITION NEAR 21.1N4 120.5E8.
TROPICAL DEPRESSION (TD) 07W, LOCATED APPROXIMATELY 65 NM 
SOUTH OF TAIWAN, HAS TRACKED EAST-NORTHEASTWARD AT 13 KNOTS OVER THE 
PAST 6 HOURS. THE WARNING POSITION IS BASED ON A 071201Z1 SPECIAL 
SENSOR MICROWAVE IMAGE (SSMI) PASS AND 071130Z2 INFRARED SATELLITE 
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT 
INTENSITY ESTIMATES OF 30 TO 35 KTS. ANIMATED SATELLITE IMAGERY 
REVEALS CYCLING DEEP CONVECTION MAINLY EAST-SOUTHEAST OF THE LOW 
LEVEL CIRCULATION CENTER (LLCC). THE SSMI AND RECENT TROPICAL 
RAINFALL MEASUREMENT MISSION (TRMM) PASSES INDICATE THAT THE LLCC 
CONTINUES TO BE BROAD, BUT HAS IMPROVED ORGANIZATION OVER THE PAST 
12 HOURS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 071200Z0 IS 12 FEET. 
REFER TO WWPW31 RJTX FOR ADDITIONAL SEA HEIGHT INFORMATION.
