The Regional Meteorological Centre (RMC) in Chennai has issued a heavy rainfall alert for several districts of Tamil Nadu over the coming days, with gusty winds reaching speeds of up to 50 kmph expected on Tuesday, 6 May. The forecast is driven by a weather trough stretching from Madhya Pradesh to Tamil Nadu, currently passing through the Gulf of Mannar region.
Districts Under Alert
The trough passes through Theni, Dindigul, Karur, Tiruchy, Namakkal, Erode, and the Nilgiris, making these districts particularly vulnerable to intense rainfall and strong winds. On Wednesday, the RMC has forecast heavy rain and gusty conditions specifically in hilly and western districts, including Nilgiris, Tiruppur, Theni, Tenkasi, Tirunelveli, Kanyakumari, and Coimbatore.
Widespread Rainfall Expected on 7 May
The weather department has predicted widespread rainfall activity across Nilgiris, Coimbatore, Tiruppur, Erode, Theni, Tenkasi, Madurai, Virudhunagar, Tirunelveli, and Kanyakumari on 7 May. Thunderstorms accompanied by lightning and winds of around 40 kmph are likely in several southern and western districts. Districts including Dindigul, Thoothukudi, Ramanathapuram, and Sivaganga are also expected to experience moderate to heavy rain with thunderstorms over the coming days.
Special Warning for Mayiladuthurai and Pudukkottai
The RMC has specifically warned of heavy rainfall in Mayiladuthurai and Pudukkottai districts on 8 and 9 May. Intermittent showers and cloudy conditions are likely to continue across many parts of the state through the weekend, according to officials.
Advisories for Residents and Fishermen
Authorities have advised people living in vulnerable and low-lying areas to remain cautious, particularly in regions prone to landslides and waterlogging. Fishermen have been specifically warned to exercise caution before venturing into the sea due to the possibility of rough coastal weather conditions. State disaster response teams and district administrations have been asked to stay on high alert and monitor vulnerable regions as southwest monsoon conditions begin to strengthen gradually over southern India. This weather system underscores the early onset of monsoon-linked activity, and residents across the state should brace for continued disruptions through the coming week.
Point of View
Where drainage infrastructure has repeatedly failed during similar events. The phased district-specific warnings through 9 May also indicate the system is slow-moving, which could amplify cumulative rainfall totals beyond initial forecasts. Early monsoon-linked activity of this scale is a reminder that Tamil Nadu's disaster preparedness calendar needs to begin well before the official June onset.
