Chennai, April 3,2025

The Regional Meteorological Centre (RMC) has predicted rains for the next three days in some districts of Tamil Nadu.

The weather department stated that for the next three days, day temperatures are also likley to drop due to pre-monsoon showers in these districts.

The RMC also said that that light to moderate intensity rainfall with thunderstorms and lightning will be witnessed in some districts of Tamil Nadu and in Puducherry, and Karaikal due to the presence of an upper air cyclonic circulation over south India.

The RMC said districts from Nilgiris to Tirunelveli, southern districts such as Madurai to Sivagangai, and Kanyakumari may receive heavy spells over isolated places from April 3 and 4.

On April 5, rain activity may be restricted to districts closer to western ghats.

Night temperatures dropped in many interior districts on Wednesday, with Karur, one of the hottest districts, recording the lowest temperature at 21C.

However the RMC said that the observatories in Chennai City recorded 34.1C and 35.3C, which is around normal, IMD said.

The city, however, is likely to experience dry weather on Thursday, as the maximum temperature in the city and the suburbs is likely to continue to be around normal at 34C-35C.
The minimum temperature is likely to hover around 26C-27C. The skies may be partly cloudy.

On Wednesday, before sunrise, interior districts such as Dharmapuri (23C), Tirupathur (23.2C), Salem (23.3C), and Tiruthani (23.5C) recorded the lowest minimum temperatures, while Chennai’s two observatories, Nungambakkam and Meenambakkam, were relatively warmer at 27.3C and 26C.

Later in the day, districts such as Erode, where temperatures were inching towards 40C until a few days ago, recorded 37.6C the highest in the state.

Tamil Nadu has recorded 14% more rainfall than the seasonal average during the ongoing northeast monsoon.

The state received 447 mm of rainfall, surpassing the seasonal norm of 393 mm. Chennai alone received 845 mm of rain, marking a 16% increase above the average. Coimbatore also witnessed a significant rise in rainfall—47% more than usual.

These developments come in the aftermath of Cyclone Fengal, which wreaked havoc in Tamil Nadu and Puducherry between November 29 and December 1.

The cyclone brought torrential rains, followed by more showers from a low-pressure system over the southern Bay of Bengal. The disaster claimed 12 lives and submerged 2,11,139 hectares of agricultural and horticultural land, affecting 69 lakh families and 1.5 crore individuals.
