JTWC 05Z評級LOW

(1) AN AREA OF CONVECTION (INVEST 98W) HAS PERSISTED NEAR 9.8N
153.9E, APPROXIMATELY 188 NM NORTHEAST OF CHUUK. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY AND A 300515Z AMSU 89GHZ IMAGE SHOW
AN ILL-DEFINED LOW LEVEL CIRCULATION CENTER (LLCC) DEVOID OF DEEP
CONVECTION. UPPER LEVEL ANALYSIS SHOW THAT 98P IS LOCATED IN A
FAVORABLE AREA WITH LOW TO MODERATE (10-15 KNOT) VERTICAL WIND SHEAR
AND DUAL OUTFLOW ALOFT. WARM SEA SURFACE TEMPERATURES (28-30
CELSIUS) IN THE REGION ARE SUPPORTIVE FOR DEVELOPMENT. GLOBAL MODELS
DEPICT MINIMAL DEVELOPMENT AS THE SYSTEM MOVES TO THE NORTHEAST INTO
LESS FAVORABLE UPPER LEVEL CONDITIONS OVER THE NEXT 72-96 HOURS.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS LOW.
