PACIFIC OCEANS/280600Z-290600ZJUN2022//
RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 97W) PREVIOUSLY LOCATED 
NEAR 
15.5N 122.1E IS NOW LOCATED NEAR 16.7N 117.0E, APPROXIMATELY 261 NM 
WEST-NORTHWEST OF MANILA. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY (MSI) DEPICTS DEEP CONVECTION EXTENDING ACROSS THE WESTERN 
PERIPHERY OF AN EXPOSED, ILL-DEFINED LOW LEVEL CIRCULATION (LLC). A 
280226Z METOP-C PASS SHOWED AN ELONGATED AREA OF CYCLONIC TURNING 
EXTENDING NORTHEAST FROM THE ASSESSED CENTER OF 97W. THE 
SCATTEROMETER DATA INDICATES PREDOMINANTLY 10-15 KNOT WINDS AROUND 
THE LLC, AND A BAND OF HIGHER WINDS UP TO 25 KNOTS EXTENDING IN AN 
ARC ON THE WESTERN PERIPHERY UNDER THE DEEP CONVECTION. 
ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE CONDITIONS FOR DEVELOPMENT 
DEFINED BY; MODERATE EQUATORWARD AND WESTWARD OUTFLOW ALOFT, LOW 
(10KT) VERTICAL WIND SHEAR, AND VERY WARM (30-31C) SEA SURFACE 
TEMPERATURES. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT INVEST 97W 
WILL BE SLOW TO DEVELOP AS IT STRUGGLES TO CONSOLIDATE AS IT DRIFTS 
SLOWLY NORTHWARD OVER THE NEXT 24 TO 48 HOURS. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL 
PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 
HOURS IS LOW.
      (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.//
