1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 240000Z, TROPICAL DEPRESSION 27W (TWENTYSEVEN) WAS
LOCATED NEAR 9.7N 127.1E, APPROXIMATELY 55 NM EAST-NORTHEAST OF
MINDINAO, AND HAD TRACKED NORTHWESTWARD AT 03 KNOTS OVER THE PAST
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30
KNOTS GUSTING TO 40 KNOTS. SEE REF A (WTPN32 PGTW 240300) FOR
FURTHER DETAILS.
      (2) AT 240000Z, TROPICAL STORM 26W (NIDA) WAS LOCATED NEAR
8.6N 145.6E, APPROXIMATELY 290 NM SOUTH-SOUTHEAST OF GUAM, AND HAD
TRACKED WESTWARD AT 08 KNOTS OVER THE PAST SIX HOURS. MAXIMUM
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 55 KNOTS GUSTING TO 70
KNOTS. SEE REF B (WTPN31 PGTW 240300) FOR FURTHER DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 4.5N
107.2E, IS NOW LOCATED NEAR 6.2N 107.0E, APPROXIMATELY 355 NM NORTH-
NORTHEAST OF SINGAPORE. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
SHOWS DEEP CONVECTION REMAINS PERSISTENT NEAR A QUASI-STATIONARY LOW
LEVEL CIRCULATION CENTER (LLCC). ANIMATED ENHANCED WATER VAPOR
IMAGERY SHOWS CONVECTION HAS CONSOLIDATED TO THE WESTERN PERIPHERY
OF THE LLCC, WITH GOOD POLEWARD OUTFLOW PERSISTING. A 240205Z AMSU-B
IMAGE SUPPORTS THE CURRENT POSITION AND ORGANIZATIONAL STRUCTURE OF
THE LLCC. UPPER-LEVEL ANALYSIS INDICATES THE SYSTEM IS LOCATED
EQUATORWARD OF THE SUBTROPICAL RIDGE AXIS WITH RADIAL OUTFLOW AND
FAVORABLY LOW VERTICAL WIND SHEAR. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS GOOD.
SEE REF C (WTPN22 PGTW 231100) FOR FURTHER DETAILS.
      (2) NO OTHER SUSPECT AREAS.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.//
