JTWC 06Z評級Low
(1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED
NEAR 15.2N 145.4E IS NOW LOCATED NEAR 15.2N 144.6E, APPROXIMATELY
109 NM NORTH OF GUAM. ANIMATED ENHANCED INFRARED (EIR) SATELLITE
IMAGERY SHOW FLARING CONVECTION AND FRAGMENTED BANDING AROUND A
BROAD LOW LEVEL CIRCULATION (LLC). ENVIRONMENTAL ANALYSIS SHOWS
FAVORABLE CONDITIONS DUE TO A WEAKENING TRPICAL UPPER TROPOSPHERIC
TROUGH (TUTT) CELL TO THE NORTHEAST CAUSING UPPER LAYER WEAK
CONVERGENCE OVER INVEST 93W. AS THE TUTT DISSIPATES, THE OUTFLOW
WILL BECOME MORE FAVORABLE ACCOMPANIED BY LOW (10-15 KTS) VERTICAL
WIND SHEAR (VWS), AND WARM (30C) SEA SURFACE TEMPERATURES (SST).
NUMERICAL MODELS ARE IN GENERAL AGREEMENT THAT 93W WILL TRACK
NORTHWESTWARD AND DEEPEN OVER THE NEXT 24-48 HOURS. 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.
