Chennai: The Tamil Nadu government has declared a holiday for schools in Chennai and surrounding districts today due to heavy rainfall that started last night.

A well-marked low-pressure area is currently located over the southwest Bay of Bengal, near the Sri Lankan coast. This system, along with an upper-air cyclonic circulation extending up to mid-tropospheric levels, is expected to move west-northwest towards the coasts of Sri Lanka and Tamil Nadu within the next 24 hours, bringing heavy to very heavy rainfall to the region.
Several districts, including Chennai, Tiruvallur, Kancheepuram, Chengalpattu, Tiruvannamalai, Villupuram, Kallakurichi, Cuddalore, Perambalur, Tiruchy, Sivaganga, Ramanathapuram, Mayiladuthurai, Nagapattinam, Coimbatore, Tirupur, Karur, Theni, Dindigul, Madurai, Virudhunagar, Tenkasi, and Thoothukudi, have been placed under yellow alert due to the rain forecast.
The Regional Meteorological Centre (RMC) has issued orange and yellow alerts for various districts in Tamil Nadu today, referencing the low-pressure system. However, the RMC has noted that there is little chance of the system evolving into a storm.
On Wednesday, Chennai and its neighboring districts experienced moderate to heavy rainfall, which is expected to persist for the next 24 hours.
