Expected LOW over Bay pops up "96B"



AN AREA OF CONVECTION HAS PERSISTED NEAR 8.3N 89.9E,


APPROXIMATELY 630 NM EAST-SOUTHEAST OF CHENNAI, INDIA. ANIMATED

MULTISPECTRAL AND INFRARED SATELLITE IMAGERY SHOWS A LOW LEVEL

CIRCULATION CENTER (LLCC) THAT HAS STARTED TO CONSOLIDATE WITH

SPORADIC DEEP CONVECTION. HOWEVER, OVER THE PAST SIX HOURS, THE

CONVECTION HAS STARTED TO BUILD TOWARDS THE LLCC, WITH A SLIGHT

INCREASE IN ORGANIZATION. UPPER LEVEL ANALYSIS INDICATES THE LLCC IS

LOCATED TO THE NORTH OF AN UPPER LEVEL SUBTROPICAL RIDGE AXIS, WHICH

IS PROVIDING GOOD POLEWARD OUTFLOW, BUT IS ALSO CREATING A MODERATE

TO HIGH VERTICAL WIND SHEAR (VWS) ENVIRONMENT. MAXIMUM SUSTAINED

SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL

PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. BASED ON THE ORGANIZATION

OF THE LLCC AND MODERATE VWS VALUES, THE POTENTIAL FOR THE

DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24

HOURS IS POOR.
