(1) AN AREA OF CONVECTION (INVEST 90W) HAS PERSISTED NEAR
10.8N 150.8E, APPROXIMATELY 380 NM SOUTHEAST OF ANDERSEN AFB, GUAM.
RECENT ANIMATED MULTI-SPECTRAL SATELLITE IMAGERY AND 212344Z METOP-
B 89GHZ AND COMPOSITE MICROWAVE PASSES INDICATE PULSATING SHALLOW
CONVECTION SLIGHTLY WEST OF THE LOW LEVEL CIRCULATION CENTER (LLCC).
ALTHOUGH SCAT PASSES WERE A MISS, ANIMATED MSI AND SURFACE
OBSERVATIONS SHOW A BROAD, YET SYMMETRIC CIRCULATION. UPPER-LEVEL
ENVIRONMENTAL ANALYSIS SHOWS A SOUTHEASTWARD EXTENTION OF RIDGE
ORIGINATING FROM A POINT SOURCE ABOVE TS 12W (LIONROCK). ABOVE THE
LLCC, VERTICAL WIND SHEAR (VWS) IS LIGHT (5 TO 10 KNOTS) AND
DIRECTLY EAST, THE VWS IS MODERATE TO HIGH (20 TO 25 KNOTS). SSTS
ARE 29 CELSIUS AND ABOVE WITH OCEAN HEAT CONTENT HIGH. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. DUE TO THE SLIGHT
IMPROVEMENT OF THE ENVIRONMENT, THE POTENTIAL FOR THE DEVELOPMENT OF
A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
