1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 7.2N
146.4E, IS NOW LOCATED NEAR 8.5N 142.2E, APPROXIMATELY 230 NM
SOUTHWEST OF ANDERSEN AFB, GUAM. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY AND A 222134Z NOAA-18 89GHZ MICROWAVE IMAGE SHOW
DISORGANIZED, FLARING CONVECTION ASSOCIATED WITH A MID-LEVEL
CIRCULATION CENTER. A 230040Z METOP-B ASCAT PASS SHOWS A MODERATELY
DEFINED EASTERLY WAVE. THE DISTURBANCE IS CURRENTLY LOCATED IN AN
AREA OF GOOD UPPER-LEVEL DIFFLUENCE, LOW VERTICAL WIND SHEAR (5-10
KNOTS), AND WARM SEA SURFACE TEMPERATURES (29-30 CELSIUS). GLOBAL
MODELS INDICATE WEAK INTENSIFICATION AS THE SYSTEM PROPAGATES WEST-
NORTHWEST OVER THE NEXT SEVERAL DAYS. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1008 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.
(2) NO OTHER SUSPECT AREAS.
