JTWC17/06Z報中評級Low

(1) AN AREA OF CONVECTION (INVEST 98W) HAS PERSISTED NEAR
22.3N 155.2E, APPROXIMATELY 800 NM NORTHEAST OF GUAM. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY DEPICTS A FULLY EXPOSED AND WELL-
DEFINED LOW LEVEL CIRCULATION WITH POTENTIAL LOWER LEVEL BANDING
WITH THE MAJORITY OF CONVECTION SHEARED TO THE SOUTHWEST. A RECENT
162355Z ASCAT PASS REVEALED TIGHT AND WEAK LLC WITH A SMALL 20 KNOT
WIND FIELD TO THE SOUTH. UPPER LEVEL ANALYSIS INDICATES A MODERATE
ENVIRONMENT WITH 20-25 KNOTS OF VERTICAL WIND SHEAR, WEAK OUTFLOW,
AND FAVORABLE (28-29C) SEA SURFACE TEMPERATURE. GLOBAL MODELS ARE IN
GOOD AGREEMENT. MOST MODELS SHOW THE LLC REMAINING WEAK AND MOVING
SOUTHWEST WITHOUT INTENSIFICATION BEFORE BEING ABSORBED INTO ANOTHER
CIRCULATION TO THE SOUTH. GFS SHOWS INTENSIFICATION WHILE
MAINTAINING ITS OWN CIRCULATION. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1002 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 24.6N
150.0E, HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE DEVELOPMENT
OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
