Tamil Nadu has been experiencing widespread heavy rainfall across multiple districts, transforming the state’s weather landscape overnight. After a sunny start in Chennai yesterday, the evening brought intense showers to areas like Kodambakkam, Nungambakkam, Thyagarayanagar, Chepauk, and Royapettah. The heavy downpour, particularly in Pallikaranai, led to significant waterlogging, causing traffic disruptions and inconvenience to residents. The India Meteorological Department (IMD) has issued a weather warning for today, September 11, 2025, predicting heavy rainfall in Chengalpattu, Villupuram, Kallakurichi, and Cuddalore districts. This breaking news update highlights the affected regions, the impact of the rains, and the forecast for the day.

Widespread Rainfall Across Chennai and Suburbs

Chennai, the capital city of Tamil Nadu, witnessed a dramatic shift in weather on September 10, 2025. After a bright and sunny morning, the evening brought heavy rainfall to several key areas, including Kodambakkam, Nungambakkam, Thyagarayanagar, Chepauk, and Royapettah. The downpour was particularly intense in Pallikaranai, where roads were inundated with water, leading to severe traffic congestion. Commuters struggled to navigate flooded streets, and local authorities were prompted to take immediate action to address waterlogging issues in low-lying areas.

The sudden rainfall caught many residents off guard, but it also brought a much-needed respite from the heat. The IMD has forecasted that Chennai and its suburbs will continue to experience partly cloudy skies with chances of light to moderate rain accompanied by thunder and lightning today. Residents are advised to stay cautious, especially in areas prone to waterlogging, and avoid unnecessary travel during peak rainfall hours.

Heavy Rainfall in Chengalpattu and Neighboring Districts

Beyond Chennai, the neighboring Chengalpattu district experienced widespread rainfall in areas such as Kuduvanchery, Maraimalainagar, Thiruporur, Thirukkazhukundram, and Madhurantakam. The heavy showers brought relief to residents but also caused waterlogging in several low-lying areas. Local authorities have been working to clear stormwater drains to mitigate flooding risks, especially in urban zones where infrastructure is often strained during heavy rains.

The IMD’s weather warning for September 11 specifically highlights Chengalpattu, along with Villupuram, Kallakurichi, and Cuddalore, as areas likely to receive heavy rainfall today. These districts are expected to see intense showers, potentially accompanied by thunderstorms and gusty winds. Residents in these regions are urged to stay vigilant, keep essential supplies ready, and report any waterlogging or fallen trees to local authorities immediately.

Impact of Heavy Rains Across Tamil Nadu

The heavy rainfall has not been limited to Chennai and its neighboring districts. Several other parts of Tamil Nadu have also been significantly affected. In Thiruvallur district, roads were flooded due to intense showers, with rainwater even overflowing the steps of the iconic Murugan temple. The flooding caused disruptions for devotees and residents alike, prompting local authorities to deploy emergency response teams to manage the situation.

In Tiruvannamalai district, the Vandavasi area saw heavy rain accompanied by thunder and lightning, much to the delight of local farmers. The rainfall is expected to benefit paddy cultivation, providing a much-needed boost to agricultural activities in the region. Similarly, in Salem district, areas like Korimedu, Astampatti, Arisi Palayam, Ammapettai, and Suramangalam experienced heavy showers, creating a cooler atmosphere and aiding agricultural efforts.

Krishnagiri and Dharmapuri: Waterlogging Challenges

In Krishnagiri district, heavy rains lashed areas such as Hosur, Madigiri, Jujuwadi, Bagalur, and Soolagiri, leading to waterlogging in low-lying areas. The accumulation of water on roads caused significant inconvenience to commuters, with local authorities working to clear drainage systems to prevent further flooding. In Dharmapuri district, areas like Pennagaram, Aroor, Pappireddipatti, and Morappur experienced heavy rainfall for over an hour, further exacerbating waterlogging issues in urban and semi-urban areas.

The heavy rainfall in these districts has highlighted the need for improved urban planning and infrastructure to handle monsoon-related challenges. Local administrations have been proactive in mobilizing disaster response teams and placing rescue boats on standby in flood-prone zones to ensure resident safety.

Agricultural Benefits in Rural Areas

While urban areas faced challenges due to waterlogging, rural regions of Tamil Nadu have largely welcomed the heavy rainfall. In Karur district, areas like Kulithalai, Manathattai, Lalapettai, Magilipatti, and Pillapalayam saw heavy showers for about an hour, benefiting farmers engaged in paddy cultivation. The rains have replenished water bodies and provided much-needed moisture to crops, raising hopes for a bountiful harvest.

Similarly, in Thanjavur district, heavy rain fell for over an hour in areas like Vallam, Karambai, Vadakal, and Vilar. Farmers in these regions expressed joy as the rainfall supported their agricultural activities. In Thiruvarur district, areas such as Senthamangalam, Pulivalam, and Mangudi also experienced prolonged showers, bringing smiles to farmers who rely on the monsoon for their livelihoods.

Severe Impact in Madurai and Perambalur

Madurai district faced significant challenges due to heavy rainfall in areas like Thirumangalam, Simmakkal, Avaniyapuram, and Mattutthavani. The downpour led to knee-deep water accumulation in key areas such as Periyar Bus Stand and Simmakkal, severely impacting daily life. Residents in Aarapalayam suffered as rainwater entered residential areas, causing distress and prompting calls for better drainage systems in the city.

In Perambalur district, areas like Siddeli and Kunnam were hit by heavy rains, with more than two feet of water covering the road near the Perambalur four-way junction. This led to significant traffic disruptions, with commuters facing delays and difficulties navigating the flooded roads. Local authorities have been working to address these issues, but the intensity of the rainfall has posed challenges to infrastructure in the region.

Theni: A Cooler Atmosphere

In Theni district, heavy rainfall in areas like Andipatti, Chinnamanur, and Uttampalayam brought a refreshing change to the local climate. The showers, accompanied by thunder and lightning, created a cooler atmosphere, much to the relief of residents who had been grappling with warmer temperatures. The rainfall is expected to benefit agriculture in the region, particularly for crops that thrive in cooler, wetter conditions.

IMD’s Weather Warning for September 11, 2025

The India Meteorological Department has issued a specific weather warning for September 11, 2025, forecasting heavy rainfall in Chengalpattu, Villupuram, Kallakurichi, and Cuddalore districts. The IMD attributes these conditions to a cyclonic circulation in the Bay of Bengal, which is expected to bring intense showers and thunderstorms to these areas. The weather agency has advised residents to avoid unnecessary travel, stay indoors during lightning activity, and keep emergency supplies ready in case of power disruptions.

The IMD has also cautioned fishermen against venturing into the Bay of Bengal due to rough sea conditions expected on September 11. Strong winds with speeds of 30 to 40 kmph are likely to accompany the rainfall, posing risks to coastal areas. District administrations in the affected regions have set up emergency helplines and mobilized disaster response teams to handle any potential crises.

Preparations and Safety Measures

In response to the heavy rainfall and the IMD’s weather warning, local authorities across Tamil Nadu have taken proactive measures to mitigate risks. Urban bodies have been clearing stormwater drains to minimize flooding, while rescue boats have been placed on standby in flood-prone areas. The State Disaster Management Authority (SDMA) has urged residents to stay informed about weather updates and follow safety advisories to avoid mishaps during the heavy rainfall.

Residents are encouraged to report waterlogging, fallen trees, or other emergencies to local authorities immediately. Emergency helplines have been activated across the affected districts, and disaster response teams are on high alert to ensure the safety of residents during this period of intense rainfall.
