REMARKS:
220300Z7 POSITION NEAR 21.1N4 137.7E8.
TROPICAL STORM (TS) 29W IS LOCATED APPROXIMATELY 665NM EAST-
SOUTHEAST OF NAHA, OKINAWA. THE SYSTEM HAS TRACKED WESTWARD AT 15 
KNOTS OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 
212330Z1 VISIBLE AND INFRARED SATELLITE IMAGERY. THE WARNING 
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 35 
KNOTS. ANIMATED SATELLITE IMAGERY INDICATES AN INCREASE IN THE 
ORGANIZATION OF THE CONVECTION AROUND A LOW LEVEL CIRCULATION CENTER 
(LLCC) DURING THE PAST 6 HOURS. A 212317Z6 SPECIAL SENSOR MICROWAVE 
IMAGER PASS INDICATES A CLEARLY DEFINED LLCC WITH THE MAJORITY OF 
THE CONVECTION LOCATED IN THE NORTHEASTERN QUADRANT.  UW-CIMSS 
ANALYSIS INDICATES THE SYSTEM IS IN AN ENVIRONMENT OF 5 TO 10 KNOTS 
OF VERTICAL WIND SHEAR. TS 29W IS FORECAST TO TRACK WESTWARD UNDER 
THE STEERING INFLUENCE OF A SUBTROPICAL RIDGE LOCATED TO THE NORTH. 
THE SYSTEM IS FORECAST TO INTENSIFY AT A CLIMATOLOGICAL RATE. 
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 220000Z4 IS 12 FEET. REFER TO 
WWPW30 RJTX FOR ADDITIONAL SEA HEIGHT INFORMATION. NEXT WARNINGS AT 
220900Z3 (DTG 220751Z7), 221500Z0 (DTG 221351Z4), 222100Z7 (DTG 
221951Z0) AND 230300Z8 (DTG 230151Z2).//
