IMD weather alert: Chennai braces for a rainy weekend; Yellow Alert issued

The Regional Meteorological Centre (RMC) in Chennai has issued a yellow alert for heavy rainfall in isolated parts of Tamil Nadu, forecasting wet weather through Sunday, April 6. The alert comes as a cyclonic circulation over the Comorin area and its neighboring regions triggers widespread showers across the state, providing much-needed respite from soaring temperatures. Residents of Chennai woke up to heavy downpours on Thursday morning, with many taking to social media to share visuals of rain-soaked streets and overcast skies.
If reports are to go by, the cyclonic circulation is expected to sustain a wet spell until April 8, with summer showers likely to intensify in the southern districts and along the Western Ghats. It is also reported that heavy rainfall is anticipated in isolated areas, particularly in the Western Ghats districts stretching from Nilgiris to Tirunelveli, as well as parts of southern Tamil Nadu, including Madurai and Virudhunagar, on Thursday.

It is also reported that maximum temperatures in the city are expected to hover between 34-35 degrees Celsius. Those residing in Tamil Nadu and Puducherry can expect below normal temperature over the next few days.

Thursday’s unexpected rainfall in Chennai took many by surprise, leaving commuters to wade through waterlogged streets while residents shared glimpses of the sudden weather change online. According to the Regional Meteorological Centre (RMC), the city may avoid the most intense showers, but certain areas across Tamil Nadu are likely to experience heavier rain.
