The Regional Meteorological Centre (RMC) has forecast heavy rainfall accompanied by strong winds across six districts of Tamil Nadu on Saturday, 28 June 2025, as an upper-air trough stretching from coastal Andhra Pradesh to central Maharashtra through Telangana continues to drive moisture-laden weather over southern India. Residents in the affected zones have been urged to exercise caution, while fishermen have been warned to stay off the sea until 30 June.
Districts on Alert
The RMC has specifically predicted heavy rain and gusty winds in Chennai, Tiruvallur, Kancheepuram, Chengalpattu, Tiruvannamalai, and Ranipet districts on Saturday. Authorities have cautioned that the combination of intense showers and strong winds could trigger waterlogging, traffic disruptions, and localised damage in these areas.
Scattered rainfall is also expected across several parts of Tamil Nadu and the Union Territories of Puducherry and Karaikal over the coming week, according to the weather department.
Rainfall Outlook for the Coming Days
The weather system is forecast to shift its intensity southward over the weekend. On Sunday, heavy rainfall is likely over the hilly regions of Virudhunagar, Tenkasi, and Tirunelveli districts. Moderate to heavy rain is also expected across the Nilgiris, Coimbatore, Tiruppur, Dindigul, Theni, Madurai, and Kanyakumari districts in the days ahead.
Meteorologists noted that prevailing atmospheric conditions are enhancing moisture inflow into Tamil Nadu, sustaining widespread rainfall activity across the state.
Marine Warning for Fishermen
The weather department has issued a marine warning for fishermen operating along the southern Tamil Nadu coast. Wind speeds of up to 60 kmph are likely over the South Tamil Nadu coastal waters, the Gulf of Mannar, and the Comorin Sea until 30 June 2025. Fishermen have been strongly advised not to venture into these waters during this period owing to rough sea conditions and the possibility of squally weather.
Impact on Daily Life and Public Advisory
While the showers are expected to bring some relief from prevailing heat, officials have warned that intense rainfall in certain areas could cause temporary flooding in low-lying regions and disrupt normal life. Authorities are closely monitoring the evolving weather system and have urged the public to follow official weather bulletins and local advisories for their safety.
Point of View
Where even moderate waterlogging cascades into traffic paralysis and infrastructure strain. The marine warning extending to 30 June is notably broad, covering three distinct water bodies, which suggests the RMC is treating this upper-air trough as a sustained system rather than a passing spell. What mainstream coverage often underplays is the cumulative risk: back-to-back rain days in low-lying coastal districts without adequate stormwater capacity can turn a 'moderate' weather event into a public health and civic emergency. The onus now falls on district administrations to pre-position pumps and emergency teams before Saturday's onset.
