/SOUTH PACIFIC OCEANS/210600Z-220600ZJAN2022//
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 15.4S 172.0W IS NOW LOCATED NEAR 15.3S 170.9W, APPROXIMATELY 62 
NM SOUTH-SOUTHWEST OF PAGO PAGO, AMERICAN SAMOA. ANIMATED ENHANCED 
INFRARED SATELLITE IMAGERY AND A 210353Z SSMIS 91GHZ PASS DEPICT 
CONVECTION SHEARED TO THE NORTH OF A LOW LEVEL CIRCULATION.  
ENVIRONMENTAL ANALYSIS INDICATES UNFAVORABLE CONDITIONS FOR 
DEVELOPMENT DEFINED BY WEAK OUTFLOW ALOFT AND MEDIUM TO HIGH (15-
20KT) VERTICAL WIND SHEAR; OFFSET BY WARM (29-30C) SEA SURFACE 
TEMPERATURES. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 91P WILL 
CONTINUE ALONG ITS SOUTH-SOUTHEASTWARD TRACK OVER THE NEXT 24-48 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 
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 LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
