Chennai, October 23, 2025: Schools across many parts of Tamil Nadu may remain closed on October 24, 2025, as heavy to very heavy rainfall continues to lash several districts. The India Meteorological Department (IMD) has issued Red, Orange, and Yellow alerts for various regions due to the ongoing northeast monsoon and the presence of twin low-pressure systems over the Bay of Bengal and Arabian Sea.
Reason for Possible School Closures
The northeast monsoon has intensified over Tamil Nadu, bringing continuous and widespread rain. Two low-pressure areas—one in the Bay of Bengal and another in the Arabian Sea—are strengthening, increasing the risk of heavy rainfall and potential flooding in low-lying areas.
Authorities are monitoring the situation closely, and district administrations are likely to declare school holidays depending on local weather conditions. The Chief Minister has directed officials to ensure all precautionary measures are in place, including relief camps and flood-prevention systems.

The IMD’s latest weather forecast indicates that heavy to extremely heavy rainfall is likely to continue across several districts of Tamil Nadu until October 24. Thunderstorms, lightning, and gusty winds are also expected in some regions.
