JTWC 06Z評級"Medium",但看好發展的數值依然不多
2) THE AREA OF CONVECTION (INVEST 97W) PREVIOUSLY LOCATED
NEAR 14.7N 148.6E, IS NOW LOCATED NEAR 15.9N 146.8E, APPROXIMATELY
200 NM NORTHEAST OF GUAM. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS A CONSOLIDATING LLCC OBSCURED BY FLARING CONVECTION
BEGINNING TO TAKE ON SOME ROTATION. ENVIRONMENTAL ANALYSIS SHOWS THE
REGION IS OVERALL FAVORABLE TO DEVELOPMENT, WITH LOW (5-10 KNOTS)
VWS, ADEQUATE UPPER LEVEL DIVERGENCE, AND WARM (28-29C) SSTS. GLOBAL
MODELS GENERALLY KEEP 97W AS A REGION OF SHARP TROUGHING WITH
ASSOCIATED ENHANCED WINDS ON A NORTHWESTWARD TRACK, POSSIBLY
INTERACTING WITH TS 18W OR ANOTHER SYSTEM DEVELOPING IN THE ECS
TOWARDS THE END OF THE MODEL RUN. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO
MEDIUM.
