REMARKS:
141500Z1 POSITION 13.9N3  125.9E7
LATEST INFRARED SATELLITE IMAGERY SHOWS THE PARTIALLY
EXPOSED LOW-LEVEL CIRCULATION ASSOCIATED WITH TROPICAL
STORM MORT (31W) IS LOCATED APPROXIMATELY 60 NM FROM THE
CONVECTION. THE LOW-LEVEL CENTER HAS INCREASED FORWARD
SPEED TO 12 KNOTS AND IS FORECAST TO MAINTAIN THIS SPEED
UNTIL IT APPROACHES LAND TOWARDS THE 24 HOUR PERIOD. TS
MORT IS EXPECTED TO REMAIN AT 35 KNOTS INTENSITY THROUGH
THE 12 HOUR PERIOD AT WHICH POINT INTERACTION WITH LAND
WILL SLOWLY WEAKEN THE SYSTEM THROUGH THE REMAINDER OF
THE FORECAST PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
141200Z8 IS 15 FEET. REFER TO WWPW30 PGFW FOR ADDITIONAL
SEA HEIGHT INFORMATION. NEXT WARNINGS AT 142100Z8 (DTG
141953Z3), 150300Z9 (DTG 150153Z5), 150900Z5 (DTG
150753Z1) AND 151500Z2 (DTG 151353Z8).//
