1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED
NEAR 5.6N 143.1E IS NOW LOCATED NEAR 5.9N 141.5E, APPROXIMATELY 488
NM SOUTH-SOUTHWEST OF GUAM. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY AND A 120858Z SSMIS 91GHZ MICROWAVE IMAGE REVEAL FLARING,
DEEP CONVECTION IN THE NORTHEASTERN PERIPHERY OF THE ASSESSED LOW
LEVEL CIRCULATION CENTER (LLCC). A 121030Z ASCAT-A SCATTEROMETRY
PASS INDICATES A DISORGANIZED LLCC ON THE SOUTHWESTERN EDGE OF
FLARING DEEP CONVECTION, WITH WINDS OF 20-25 KTS IN THE NORTHEASTERN
QUADRANT OF THE CIRCULATION AND 15-20 KTS ELSEWHERE. INVEST 94W IS
IN A FAVORABLE ENVIRONMENT FOR TROPICAL DEVELOPMENT WITH ROBUST
WESTWARD AND EQUATORWARD OUTFLOW ALOFT, LOW (5-10 KTS) VERTICAL WIND
SHEAR, AND WARM (29-30C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE
IN GOOD AGREEMENT THAT INVEST 94W WILL STEADILY INTENSIFY AS IT
TRACKS TO THE NORTHWEST OVER THE NEXT 24 HOURS.  MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 18 TO 23 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 IS UPGRADED TO HIGH.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA. 1.B.(1) TO
HIGH.//
