REMARKS:
142100Z8 POSITION 14.2N7  125.5E3
ANIMATED INFRARED SATELLITE IMAGERY INDICATES OVER
THE PAST 3 HOURS CONVECTION HAS BECOME BETTER ORGANIZED
AND MORE CENTRALLY LOCATED TO TROPICAL STORM MORT (31W).
THE FORECAST INTENSITY IS BASED ON A COMBINATION OF
NUMEROUS SYNOPTIC SHIP REPORTS AND A SATELLITE DERIVED
INTENSITY ESTIMATE OF BETWEEN 45 AND 55 KNOTS. THE
FORECAST TRACK CONCURS WITH THE PREVIOUS FORECAST,
HOWEVER THE FORECAST INTENSITIES HAVE BEEN ADJUSTED
SLIGHTLY BASED ON THE RECENT INCREASE IN CONVECTION AND
INTENSITY. THE SYSTEM IS EXPECTED TO WEAKEN SLOWLY
THROUGHOUT THE FORECAST PERIOD AS IT APPROACHES THE
PHILLIPINE ISLAND OF LUZON. THIS SYSTEM WILL BE MONITORED
CLOSELY FOR ADDITIONAL ORGANIZATION AND INCREASE IN
INTENSITY. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 141800Z4 IS
15 FEET. REFER TO WWPW31 PGFW FOR ADDITIONAL SEA HEIGHT
INFORMATION. NEXT WARNINGS AT 150300Z9 (DTG 150153Z5),
150900Z5 (DTG 150753Z1), 151500Z2 (DTG 151353Z8) AND
152100Z9 (DTG 151953Z4).//
