REMARKS:
210900Z2 POSITION NEAR 21.9N2 144.5E4.
TROPICAL STORM (TS) 21W (PARMA), LOCATED APPROXIMATELY 250 NM SOUTHEAST
OF IWO JIMA, HAS TRACKED NORTHEASTWARD AT 06 KNOTS OVER THE PAST 06 HOURS.
THE WARNING POSITION IS BASED ON 210530Z1 MULTISPECTRAL SATELLITE IMAGERY.
THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF
35 KNOTS. THE 210000Z3 LOCATION OF TS 21W HAS BEEN RELOCATED 75 NM EAST OF
THE 210000Z3 WARNING LOCATION. AVAILABILITY OF VISIBLE SATELLITE IMAGERY,
A 201952Z9 TROPICAL RAINFALL MEASURING MISSION PASS, AND A 202352Z4 SSM/I
PASS SHOWS THAT THE LOW LEVEL CIRCULATION CENTER FOR TS 21W IS LOCATED
SIGNIFICANTLY FURTHER EAST THAN WHAT THE PREVIOUS INFRARED SATELLITE FIXES
WERE SHOWING. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 210600Z9 IS 11 FEET. REFER
TO WWPW30 RJTX FOR ADDITIONAL SEA HEIGHT INFORMATION. NEXT WARNINGS AT
211500Z9, 212100Z6, 220300Z7 AND 220900Z3. REFER TO TYPHOON  20W (KETSANA)
