Schools in Tamil Nadu will stay closed on Wednesday, December 3, 2025 . This holiday is because of heavy rain and bad weather. Cyclone Ditwah has hit the eastern coast, bringing strong winds and rain. Districts such as Chennai , Chengalpattu , and Tiruvallur are especially affected. Weather experts have warned of heavy rainfall due to a strong weather system, called a deep depression, over the Bay of Bengal. This deep depression is causing rain in many parts of Tamil Nadu. The state government has decided to keep schools shut to ensure the safety of students and staff.
An Orange Alert has been issued for several areas. These districts include Chennai , Ranipet , Chengalpattu , and Kancheepuram . An Orange Alert means people should be prepared for bad weather and take necessary steps. Residents in these areas are strongly advised to stay inside their homes. They should avoid going out unless it is urgent. This measure helps to prevent accidents and keep everyone safe during the storm. Sadly, three deaths have already been reported in Tamil Nadu due to rain-related incidents. These incidents show how serious the current weather situation is across the state.
Cyclone Ditwah made its landfall in the Bay of Bengal . This means it moved from the sea onto land. After landfall, the cyclone is slowly moving towards the northwest direction. As it moves, it brings more rain. Areas like Chennai , Puducherry , and parts of southern Andhra Pradesh are getting heavy to moderate rainfall. Waterlogging, where streets and low-lying areas fill with water, has become common. District authorities decided on the school holiday. This was to make sure that students and school staff stay safe. It also prevents any difficulties caused by flooded roads or damaged areas.
Many government schools in Tamil Nadu were also closed on Tuesday, December 2 . The holiday for Wednesday, December 3 , is an extension of these closures due to the continuing bad weather. Besides the rain, there is another reason for a holiday in one specific district. In Kanyakumari District , schools and colleges will observe a holiday for the Kotta Peralaya festival . This festival is an important local event. So, students in Kanyakumari have a holiday for both the festival and the rain. This ensures all students across affected areas receive proper notice for their safety.
