RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   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:
      (1) THE AREA OF CONVECTION (INVEST 91P) PREVIOUSLY LOCATED 
NEAR 14.5S 146.5E IS NOW LOCATED NEAR 14.4S 146.3E, APPROXIMATELY 
150 NM NORTH OF CAIRNS, AUSTRALIA. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY AND A 161115Z METOP-B 89GHZ MICROWAVE IMAGE SHOW A 
CONSOLIDATING CIRCULATION WITH FLARING CONVECTION THROUGHOUT. A 
161208Z ASCAT-C PARTIAL PASS SHOWS 25-30KT WINDS WITHIN THE WESTERN 
PORTION THE LOW LEVEL CIRCULATION. ENVIRONMENTAL ANALYSIS INDICATES 
THAT INVEST 91P IS IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH 
LOW (<15 KTS) VERTICAL WIND SHEAR, GOOD OUTFLOW ALOFT, AND WARM (29-
30C) SEA SURFACE TEMPERATURES. GLOBAL MODELS DO NOT DEPICT FURTHER 
INTENSIFICATION OF THIS SYSTEM, BUT HAVE UNDER-PREDICTED DEVELOPMENT 
THUS FAR. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 999 MB. 
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO 
MEDIUM.//
