Low-pressure over Bay of Bengal

The India Meteorological Department (IMD) has officially mounted a watch for a low-pressure area (‘low’) to form over the Southwest Bay of Bengal by tomorrow, the Hindu website reported.
This is even as a cyclonic circulation persisted over the Comorin region, just to the west-northwest.
The low would be closely monitored for signs of intensification, possibility for which has already hinted at by a number of international weather models.
The US Navy’s Joint Typhoon Warning Centre located the ‘suspect’ area of convection (enhanced evaporation and cloud building) about 425 km west-southwest of Colombo, Sri Lanka.
It also features a low-level circulation centre, the nucleus around which the storm builds.
Seawaters are warmest from the Southwest Bay of Bengal off Sri Lanka, and this pool of very warm waters now extends into the Andaman Sea to the extreme Southeast.
A building storm seeks out the warmest of waters to grow in strength, aided by convection and cloud-building.
Rain or thundershowers have been forecast over the Andaman and Nicobar Islands, Lakshadweep, South Karnataka and Kerala over the next two days.
Convective (rain-bearing) clouds hovered above Kerala, Tamil Nadu, South Bay of Bengal, Comorin area and the adjoining Southeast Arabian Sea.
