JTWC評級Low

(1) AN AREA OF CONVECTION (INVEST 97B) HAS PERSISTED NEAR
19.5N 88.5E, APPROXIMATELY 180 NM SOUTH FROM KOLKATA, INDIA.
ANIMATED ENHANCED INFRARED IMAGERY AND A 131515Z METOP-B 89GHZ
REVEAL A LACK OF CONVECTIVE STRUCTURE. A BROAD AREA OF TROUGHING IS
REVEALED IN A 131400Z ASCAT-A IMAGE. INVEST 97B IS IN AN ENVIRONMENT
THAT IS NOT FAVORABLE FOR DEVELOPMENT WITH HIGH (40-50 KT) VERTICAL
WIND SHEAR, STRONG EQUATORWARD OUTFLOW, AND WARM (30-31C) SEA
SURFACE TEMPERATURES. DESPITE THE UNFAVORABLE UPPER LEVELS, GLOBAL
MODELS GENERALLY AGREE THAT 97B WILL CONSOLIDATE AND MARGINALLY
STRENGTHEN AS IT SLOWLY TRACKS NORTHWESTWARD. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 998 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.
