JTWC Low
AN AREA OF CONVECTION (INVEST 97W) HAS PERSISTED NEAR
18.8N 158.2E, APPROXIMATELY 848 NM EAST-NORTHEAST OF GUAM. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY DEPICTS A VERY BROAD, ASYMMETRIC LOW
LEVEL CIRCULATION (LLC) WITH A LARGE AREA OF FLARING DEEP CONVECTION
TO THE SOUTH. THIS IS REFLECTED IN A 252028Z SSMIS 91GHZ MICROWAVE
IMAGE, REVEALING A DISTINCT LACK OF CONVECTION OVER THE LLC AND
FRAGMENTED DEEP CONVECTION RELEGATED TO THE SOUTHERN PERIPHERY. A
252252Z METOP-B ASCAT PASS SHOWS A CONFUSED, WEAK WIND FIELD WITH NO
DISTINCT CIRCULATION AND A LARGE SWATH OF 15 TO 20 KNOT WINDS
EXTENDING TO THE NORTH-EAST. 97W IS CURRENTLY EXPERIENCING A
FAVORABLE ENVIRONMENT WITH EXCELLENT EQUATORWARD OUTFLOW, LOW (5 TO
10 KNOT) VERTICAL WIND SHEAR, AND WARM (30 TO 31 CELSIUS) SEA
SURFACE TEMPERATURES. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 97W
WILL TRACK GENERALLY NORTHWARD WHILE INTENSIFYING. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1010 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW. |
