REMARKS:
120900Z2 POSITION 13.2N6  134.4E2
TROPICAL STORM MORT (31W) HAS TRACKED WEST-NORTHWESTWARD
AND HAS CONTINUED TO INTENSIFY AND BECOME BETTER
ORGANIZED DURING THE PAST 06 HOURS. A SMALL CENTRAL DENSE
OVERCAST FEATURE HAS DEVELOPED OVER THE LOW-LEVEL CENTER
AND HAS INCREASED IN DIAMETER. NUMEROUS CLOUD TOPS AS
COLD AS -83C TO -86C HAVE ENCIRCLED THE SYSTEM CENTER.
THE WARNING INTENSITY IS BASED ON 120530Z1 SATELLITE-
DERIVED CURRENT INTENSITY ESTIMATES OF CI 3.5 (55 TO 60
KNOTS) FROM JTWC AND KGWC SATELLITE ANALYSTS, AND THE
VERY COLD TOPS NEAR THE SYSTEM CENTER. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 120600Z IS 16 FEET. REFER TO
WWPW30 PGFW FOR ADDITIONAL SEA HEIGHT INFORMATION. NEXT
WARNINGS AT 121500Z9 (DTG 121353Z5), 122100Z6 (DTG
1953Z1), 130300Z7 (DTG 130153Z3) AND 130900Z3 (DTG
