Tamil Nadu Weather: IMD issues heavy rain alert in 6 districts owing to low-pressure system in Bay of Bengal

First Published | Dec 11, 2024, 4:19 PM IST

A low-pressure area formed in the southwest Bay of Bengal is moving towards Tamil Nadu. The Meteorological Department has issued a heavy rain warning for coastal districts today.

Following the onset of the northeast monsoon, Cyclone Fengal caused significant damage. Now, there are reports of the possibility of another cyclone forming. The deep depression that prevailed over the southwest and adjoining southeast Bay of Bengal this morning at 8:30 a.m. is now located over the southwest Bay of Bengal off the coast of Sri Lanka. It is likely to move west-northwestwards towards the Sri Lankan and Tamil Nadu coasts over the next 24 hours.

Due to this, light to moderate rain with thunder and lightning is likely to occur at most places in coastal Tamil Nadu today, at a few places in interior Tamil Nadu, and in Puducherry and Karaikal.
