REMARKS:
152100Z9 POSITION 18.6N5  142.4E1
DURING THE PAST 12 HOURS, TROPICAL DEPRESSION 31W HAS TRACKED NORTH-
WESTWARD AND INTENSIFIED SLIGHTLY AS DEEP CONVECTION HAS RE-DEVELOPED
OVER THE SYSTEM CENTER WITH POSSIBLE DEVELOPMENT OF A CENTRAL DENSE
OVERCAST FEATURE. SINCE TD 31W HAS HAD A HISTORY OF LARGE FLAREUPS
OF CONVECTION AND THEN DISSIPATION, WE HAVE HELD OUR INTENSITIES
DOWN UNTIL A PERSISTENT CONVECTIVE PATTERN EMERGES. MINIMUM SEA-LEVEL
PRESSURE IS ESTIMATED TO BE 1000 MB. TD 31W IS A SMALL, MIDGET-LIKE
TROPICAL CYCLONE AND, AS A RESULT, WE HAVE KEPT THE WIND RADII SMALL.
NEXT WARNINGS AT 160300Z0 (DTG 160153Z6), 160900Z6 (DTG 160753Z2),
161500Z3 (DTG 161353Z9) AND 162100Z0 (DTG 161953Z5). MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 151800Z IS 10 FEET. REFER TO WWPW31 PGFW
FOR ADDITIONAL SEA HEIGHT INFORMATION. REFER TO TROPICAL DEPRESSION
30W (ABEL) WARNINGS (WTPN31 PGTW) FOR TWELVE-HOURLY UPDATES.
REFER TO TROPICAL STORM BETH (32W) WARNINGS (WTPN33 PGTW) FOR
SIX-HOURLY UPDATES.//
