JTWC 20Z評級LOW

(2) AN AREA OF SHARP TURNING (INVEST 90W) AT THE NORTHWESTERN
EXTENT OF AN ACTIVE MONSOON TROUGH HAS PERSISTED NEAR
16.2N 125.4E, APPROXIMATELY 270 NM EAST-NORTHEAST OF MANILA,
PHILIPPINES. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY DEPICTS A
VERY BROAD LOW LEVEL CIRCULATION WITH FLARING CONVECTION LOCATED
MOSTLY TO THE WEST OF ITS CENTER. THE DISTURBANCE IS CURRENTLY
LOCATED IN A MOSTLY FAVORABLE ENVIRONMENTAL DUE TO GOOD UPPER LEVEL
DIVERGENCE, LOW TO MODERATE VERTICAL WIND SHEAR (15-20 KNOTS), AND
VERY WARM SEA SURFACE TEMPERATURES (30-31 CELSIUS). GLOBAL MODEL
GUIDANCE IS CURRENTLY INDICATING THAT INVEST 90W MAY CONSOLIDATE OR
POTENTIALLY MERGE WITH INVEST 98W TO FORM A TROPICAL CYCLONE OVER
THE NEXT 48 HOURS WHILE TRACKING WESTWARD NEAR THE TIP OF LUZON.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS LOW.

(2) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 15.2N
125.6E HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE DEVELOPMENT
OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
