Tamil Nadu Weather: Heavy rainfall alert for Chennai, other 4 districts till December 1st

Intensified Northeast Monsoon

The northeast monsoon has intensified in Tamil Nadu. A deep depression in the southeast Bay of Bengal has strengthened into a low-pressure area. It is moving northwest, causing heavy rain from the delta districts to Chennai, as warned by the Meteorological Department. Private weather analyst, Tamil Nadu Weatherman Pradeep John, stated:

5 Days of Rain in Chennai

Chennai will see good rainfall for 4-5 days, starting today. Delta regions like Nagai, Mayiladuthurai, Karaikal, Thanjavur, and Ramanathapuram will experience heavy downpours today. Cuddalore and Pandi will also receive heavy rainfall. The low-pressure area is located below Sri Lanka and has started moving north. Due to its slow movement and stagnation, Tamil Nadu's coastal areas will experience rain for the next 4-5 days, until November 1st.

Rain Until December 1st

Rain will start in Chennai and surrounding districts today. Good cloud cover is moving in. Chennai will see rain picking up from the 27th and continuing until December 1st. If the deep depression crosses the coast below Chennai, rain will also occur when it crosses the north coast. So, Chennai will have many rainy days. Enjoy the rain from today until December 1st.

Parking on Bridges?

Should cars be parked on bridges, should people stay in lodges, should supermarkets be emptied? I'm not going to advise anything like that. Chennai needs rain now. Poondi reservoir, which supplies drinking water to Chennai, is at 15% capacity, Chembarambakkam at 59%, and Red Hills at 71%. So, will Chennai face water scarcity in 2025? No. I expect good rain in the catchment areas. This is the last major rain spell in this northeast monsoon for Chennai and surrounding districts.
