REMARKS:
150900Z5 POSITION 17.9N7  143.0E8
LATEST VISUAL SATELLITE IMAGERY FROM 15/0530Z INDICATES
THAT TROPICAL DEPRESSION 31W CONTINUES TO MOVE NORTHWEST
AT 09 KTS AND WEAKEN.  ALTHOUGH CONVECTION HAS
PERIODICALLY FLARED UP WITHIN THE SMALL CIRCULATION
CENTER, IT HAS NOT PERSISTED. TROPICAL DEPRESSION 31W IS
NOT EXPECTED TO REINTENSIFY OVER THE NEXT 36 HOURS DUE TO
STRONG UPPER LEVEL VERTICAL SHEAR OVER THE REGION. IF THE
JOINT TYPHOON WARNING CENTER ANTICIPATES THAT THIS
TROPICAL DEPRESSION WILL REACH TROPICAL STORM INTENSITY,
THEN A STANDARD 72 HOUR TROPICAL CYCLONE WARNING WILL BE
ISSUED.  OTHERWISE, 36 HOUR TROPICAL DEPRESSION WARNINGS
WILL BE UPDATED EVERY 12 HOURS. NEXT WARNINGS AT 152100Z9
(DTG 151953Z4) AND 160900Z6 (DTG 160753Z2). MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 150600Z IS 09 FEET.
REFER TO WWPW30 PGFW FOR ADDITIONAL SEA HEIGHT
INFORMATION. REFER TO TROPICAL DEPRESSION  30W WARNINGS
(WTPN31 PGTW) FOR TWELVE-HOURLY UPDATES. REFER TO
TROPICAL STORM BETH (32W) WARNINGS (WTPN33 PGTW) FOR SIX-
HOURLY UPDATES.//
