SKYMET WARNS

Skymet forecast says a low pressure area is prevailing over southwest and adjoining southeast Bay of Bengal. This weather system will gradually move towards Tamilnadu and may intensify further into a well-marked low-pressure area.

Therefore, we expect the intensity of rain to increase gradually over coastal areas of Tamilnadu, says the weatherman.
Today, there will be light rain but the weather will remain cloudy. It is anticipated that the intensity of rain will increase from tomorrow. Rain will continue intermittently till November 15.

During this time, a few heavy spells are expected which may once again lead to waterlogging in many parts of the city, cautions Skymet.

After 15 November, the weather system will start moving in a north-northeast direction, away from Tamilnadu coast, towards Odisha and Gangetic West Bengal.
