REMARKS:
312100Z7 POSITION 17.9S7 122.6E1
TROPICAL CYCLONE 14P (LES) HAS CONTINUED TO TRACK TOWARDS THE
SOUTHWEST OVER THE PAST 6 HOURS. LATEST SATELLITE IMAGERY SHOWS
LARGE AREA OF CONVECTION HAS PERSISTED OVER WATER AND LAND. THE
WARNING POSITION IS BASED ON 311730Z5 INFRARED SATELLITE
IMAGERY AND THE WARNING INTENSITY IS BASED ON A COMBINATION OF
SURROUNDING SYNOPTIC DATA AND A SATELLITE DERIVED CURRENT
INTENSITY ESTIMATE OF 45 KNOTS. THE FORECAST TRACK REMAINS
SIMILAR AS THE SYSTEM IS EXPECTED TO TRACK ALONG THE COASTLINE.
HOWEVER, AS THE SYSTEM CONTNIUES TO INTERACT WITH LAND THE
CHANCES FOR SIGNIFICANT DEVELOPMENT DIMINISH. THEREFORE, AS

PAGE 05 RUHPSGG4135 UNCLASS
TROPICAL CYCLONE 14P CONTINUES A TRACK ALONG THE COAST THE
SYSTEM IS FORECAST TO MAINTAIN ITS CURRENT INTENSITY. THE
SYSTEM IS EXPECTED TO TRACK OVER WATER BETWEEN THE 24 AND 48
HOUR PERIOD WHERE A SLIGHT INTENSIFICATION IS FORECAST
TO OCCUR. AFTERWARDS, INTERACTION WITH LAND IS EXPECTED TO
WEAKEN THE SYSTEM. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 311800Z3
IS 13 FEET. NEXT WARNINGS AT 010300Z4 (DTG 010153Z0), 010900Z0
(DTG 010753Z6), 011500Z7 (DTG 011353Z3) AND 012100Z4
(DTG 011953Z9).//
