Track of Low Pressure Area

The area of convection previously located near 17.8N 89.5E is now located near 18.2N 89.6E, approximately 265 nm south-southeast of Kolkata, India.

Animated infrared satellite imagery shows flaring deep convection associated with a developing broad low level circulation center (LLCC). Additionally, a TRMM microwave image indicates elongated low level banding.

A buoy observation located in the southern convective band indicates 1002 mb surface pressure. The LLCC is located equatorward of the subtropical ridge axis in an area of upper level divergence and moderate vertical wind shear.

Maximum sustained surface winds are estimated at 20 to 25 knots. Minimum sea level pressure is estimated to be near 1005 mb. The potential for the development of a significant tropical cyclone within the next 24 hours has been upgraded to fair.
