2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 96P) PREVIOUSLY LOCATED
NEAR 14.0S 143.6E IS NOW LOCATED NEAR 14.7S 147.6E, APPROXIMATELY
170 NM NORTHEAST OF CAIRNS, AUSTRALIA. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY, RADAR IMAGERY AND A 120342Z AMSR2 GCOM GW1 89GHZ
MICROWAVE IMAGE DEPICT A VERY BROAD, ELONGATED LOW LEVEL CIRCULATION
(LLC) WITHOUT A DEFINED CIRCULATION CENTER. EXTENSIVE DEEP
CONVECTIVE BANDING LIES ALONG THE SOUTHWESTERN EDGE OF THE LLC. A
112350Z METOP-C ASCAT PASS REVEALS 30 TO 35 KNOT STRAIGHT-LINE WINDS
RUNNING ALONG EITHER SIDE OF THE VERY ELONGATED, NORTHWEST-SOUTHEAST
ORIENTED LLC. 96P IS CURRENTLY IN A VERY FAVORABLE ENVIRONMENT WITH
NEAR RADIAL UPPER LEVEL OUTFLOW, LOW (10 TO 15 KNOT) VERTICAL WIND
SHEAR, AND WARM (30 TO 31 CELSIUS) SEA SURFACE TEMPERATURES. GLOBAL
MODELS ARE IN GOOD AGREEMENT THAT 96P WILL TRACK GENERALLY EASTWARD
WHILE REMAINING BROAD FOR THE NEXT 18 TO 36 HOURS BEFORE
CONSOLIDATING AND TURNING TO A MORE SOUTHWARD TRACK. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1001 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS REMAINS HIGH. SEE REF A (WTPS21 PGTW 111500) FOR FURTHER
DETAILS.
