JTWC評級Low
(1) AN AREA OF CONVECTION (INVEST 97B) HAS PERSISTED NEAR
20.4N 89E, APPROXIMATELY 201 NM SOUTHWEST OF DHAKA, BANGLADESH.
ANIMATED ENHANCED INFRARED SATELLITE IMAGERY DEPICS BROAD TURNING
AND DEEP CONVECTION TO THE WEST AND SOUTHWEST OF THE LOW-LEVEL
CIRCULATION CENTER (LLCC). A 161321Z 91GHZ SSMIS MICROWAVE IMAGE
ALSO DEPICTS DEEP CONVECTION DISPLACED TO THE WEST-SOUTHWEST OF THE
LLCC. UPPER-LEVEL ENVIRONMENTAL CONDITIONS ARE ONLY MARGINALLY
SUPPORTIVE OF FURTHER DEVELOPMENT, WITH VERTICAL WIND SHEAR VALUES
OF 10 TO 20 KTS AND FAVORABLE OUTFLOW TO THE NORTH AND WEST BUT
RESTRICTED ELSEWHERE. A 160332Z ASCAT PASS SHOWS A BROAD CIRCULATION
WITH MAX WINDS TO THE SOUTHWEST OF AROUND 30 KNOTS ASSOCIATED WITH
THE MONSOON FLOW. WINDS ARE LIGHTER CLOSER TO THE LLCC WITH MAXIMUM
SUSTAINED SURFACE WINDS ESTIMATED AT 15 TO 25 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.
