1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 210000Z2 TYPHOON ROSIE (10W) WAS
LOCATED AT 15.2N8 134.9E7, MOVING NORTH-NORTHWESTWARD AT
06 KNOTS.  MAXIMUM SUSTAINED WINDS WERE ESTIMATED AT 75
KNOTS WITH GUSTS TO 90 KNOTS. SEE REF A (TYPHOON ROSIE
(10W) WARNING NR 10 (WTPN31 PGTW 210300)) AND SIX-
HOURLY UPDATES FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE CONVECTION ASSOCIATED WITH THE LOW-LEVEL
CIRCULATION CENTER PREVIOUSLY LOCATED NEAR 24N6 172E0 HAS
DISSIPATED. THIS AREA IS NO LONGER CONSIDERED SUSPECT.
      (2)THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR
23N5 152E8 IS NOW NEAR 24N6 149E4.  ANIMATED VISIBLE AND
WATER VAPOR IMAGERY INDICATE A TIGHT CIRCULATION CENTER
BUILDING DOWNWARD FROM A TUTT CELL.  CONVECTION
ASSOCIATED WITH THIS AREA HAS INCREASED OVER THE PAST 24
HOURS, BUT REMAINS DISORGANIZED. ANIMATION, MULTI-
SPECTRAL IMAGERY, AND MICROWAVE IMAGERY DO NOT GIVE
EVIDENCE OF A SURFACE CIRCULATION. MAXIMUM SUSTAINED
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE 1006 MB. THE POTENTIAL FOR
SIGNIFICANT TROPICAL CYCLONE DEVELOPMENT WITHIN THE NEXT
24 HOURS IS FAIR.
      (3) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR
27N9 130E4 HAS DISSIPATED AND IS NO LONGER CONSIDERED
SUSPECT.
      (4) NO OTHER SUSPECT AREAS.
2. WESTERN SOUTH PACIFIC AREA (180 WEST TO 135E):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE
