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

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.
