REMARKS:
051500Z1 POSITION 10.6N7  152.9E7
TROPICAL STORM DALE (36W) IS QUASI-STATIONARY
APPROXIMATELY 500 NM EAST-SOUTHEAST OF GUAM. THIS WARNING
IS ISSUED AS RELOCATED BECAUSE A VECTOR DRAWN FROM THE
PREVIOUS WARNING POSITION TO THE CURRENT POSITION IS NOT
REPRESENTATIVE OF RECENT PAST MOTION. ANIMATED SATELLITE
IMAGERY CLEARLY INDICATES THE MAIN CIRCULATION CENTER
IS FURTHER EAST THAN PREVIOUSLY ANALYZED AND IT LIES
UNDER THE DEEP CONVECTION. STRONG SOUTHWESTERLY MONSOONAL
WINDS ARE FEEDING INTO THIS SYSTEM AND ARE ACCOUNTED FOR
IN THE ENLARGED WIND RADII TO THE SOUTHEAST OF TS DALE.
WARNING INTENSITY IS BASED ON A  COMBINATION OF SATELLITE
AND SYNOPTIC DATA. SATELLITE IMAGERY ANALYSIS YIELDS 35
KNOT SUSTAINED WINDS (DVORAK T2.5). SYNOPTIC DATA FROM
DRIFTING BUOYS IN THE VICINITY OF TS DALE SUPPORT A
MINIMUM CENTRAL PRESSURE BELOW 996 MB, WHILE CORRELATES
ON AVERAGE TO 37 KNOTS OR GREATER; THUS THE INTENSITY HAS
BEEN BROUGHT UP TO 40 KNOTS. NEXT WARNINGS AT 052100Z8
(DTG 051955Z5), 060300Z9 (DTG 060155Z7), 060900Z5 (DTG
060755Z3) AND 061500Z2 (DTG 061355Z0). MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 051200Z8 IS 15 FEET. REFER TO
WWPW30 PGFW FOR ADDITIONAL SEA HEIGHT INFORMATION. REFER
TO TROPICAL DEPRESSION 37W WARNINGS (WTPN32 PGTW) FOR
SIX-HOURLY UPDATES.//
