Chennai: The Regional Meteorological Centre (RMC) has forecast heavy rain across 15 districts in Tamil Nadu until November 2. The districts likely to be affected include Dindigul, Madurai, Tiruchi, Karur, Dharmapuri, Namakkal, Erode, Salem, Vellore, Krishnagiri, Tirupattur, Kallakurichi, Perambalur, Tiruvannamalai, and Ariyalur. Moderate to heavy rain is also anticipated in Puducherry and Karaikal on Thursday.
According to the RMC, this rainfall is caused by a weather system over the Gulf of Mannar and an atmospheric circulation affecting southern Andhra Pradesh. The Northeast Monsoon, which started on October 17, has already brought significant rainfall to Tamil Nadu.

The India Meteorological Department (IMD) predicts normal to above-normal rainfall for the northern parts of the state, while southern areas are expected to receive normal rainfall, though many southern districts have already experienced heavy showers. For the October to December season, the IMD anticipates above-normal rainfall, estimating that the southern peninsular region—including Kerala, Tamil Nadu, and Andhra Pradesh—will receive 112 percent of the long-term average of 33.4 cm.
Typically, Tamil Nadu receives an average of 44 cm during the northeast monsoon. Due to the expected heavy rain, the Tamil Nadu Water Resources Department (WRD) has issued a flood alert for 15 villages along the Thenpennai River. This alert follows the release of 1,000 cusecs of water per second from the Sathanur Dam in Tiruvannamalai district.
Authorities in Tiruvannamalai have advised residents of the affected villages to move to safer areas away from the riverbanks. Local panchayat and revenue officials have been directed to assist in evacuating residents from low-lying areas. Residents have also been warned against crossing the river due to rising water levels.
Additional flood alerts have been issued for the Harur and Pappireddipatti regions. Fire and Rescue Services, along with the State Disaster Response Force (SDRF), are on standby for any emergencies. The WRD began releasing water from the Sathanur Dam after the water level reached 114.5 feet, close to the dam's full capacity of 119 feet.
