Schools in many parts of Tamil Nadu may close on October 23, 2025 , due to heavy rainfall. The Indian Meteorological Department (IMD) has issued Red, Orange, and Yellow alerts across several districts. This is because of the ongoing northeast monsoon and low-pressure systems over the Bay of Bengal and Arabian Sea. Parents and students must check official announcements from government authorities and their schools for confirmed holiday information.
Why are Schools Closing?
The northeast monsoon season has brought continuous rain to Tamil Nadu. Two areas of low pressure are forming. One is in the Bay of Bengal and another in the Arabian Sea. These systems cause widespread and heavy rainfall. The IMD warns that this weather will continue, leading to possible flood-like conditions in some areas.
Chief Minister M. K. Stalin has reviewed the rain situation. He has asked officials to take steps to prevent floods and keep relief camps ready. These camps will help people who need to move from their homes due to heavy rain or flooding.
Rainfall Alerts for Tamil Nadu
The IMD uses different color-coded alerts to warn people about rainfall intensity. These alerts help local authorities prepare for severe weather. Here are the details:
- Red Alert: This is the highest alert, meaning extremely heavy rainfall is expected. Rainfall can be more than 21 cm in a day. People may experience thunderstorms, lightning, and strong winds.
- Orange Alert: This means very heavy rainfall is likely, usually between 7 cm and 20 cm in a day. People should be ready for bad weather.
- Yellow Alert: This is a warning for heavy rainfall, usually between 7 cm and 11 cm in a day. It advises people to be aware of the weather.
