RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY: NONE.
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 PREVIOUSLY LOCATED NEAR 17.9S
161.8E, IS NOW LOCATED NEAR 19.3S 166.4E, APPROXIMATELY 150 NM
SOUTHWEST OF PORT VILA, VANUATU. RECENT ANIMATED INFRARED SATELLITE
IMAGERY DEPICTS A PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER
(LLCC) WITH FLARING DEEP CONVECTION OVER THE SOUTHEASTERN PORTION. A
202157Z PARTIAL METOP-B ASCAT PASS INDICATES 25 TO 30 KNOT WINDS
ALONG THE NORTHWESTERN PERIPHERY. UPPER LEVEL ANALYSIS SHOWS
MARGINALLY FAVORABLE CONDITIONS FOR INTENSIFICATION, WITH INCREASING
EASTWARD DIFFLUENCE ALOFT, MODERATE (15-25 KNOT) VERTICAL WIND
SHEAR, AND SUPPORTIVE ALONG-TRACK SEA SURFACE TEMPERATURES (26-28C).
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 999 MB. BASED ON
THE CURRENT STRUCTURE AND MARGINALLY FAVORABLE ENVIRONMENT, THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.
(2) NO OTHER SUSPECT AREAS.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA. 2.B.(1) TO
MEDIUM.//
