Schools Shut in 5 Tamil Nadu Districts Today: October 21 Rain Holiday, IMD Rain Forecast Till Oct 26
Schools in five Tamil Nadu districts stayed closed on Wednesday, October 21, after heavy overnight rain flooded streets and slowed morning traffic. The district collectors of Chennai, Kancheepuram, Tiruvallur, Chengalpattu and Ranipet announced the holiday as a safety measure for students. The India Meteorological Department (IMD) has warned that the rain is not going anywhere soon, and families should keep an eye on official announcements.
Chennai leads the closure list after a rainy night
Chennai District Collector S. Malathi Helen ordered schools across the district to remain shut on Wednesday. The decision came after the city saw steady rain through the night, and the weather department warned of more downpours during the morning hours.
Collectors of Tiruvallur, Kancheepuram and Chengalpattu issued similar orders. Tiruvallur Collector Kavitha said schools would remain closed because of the continuous rain. Ranipet also declared a holiday, taking the total to five districts.
Officials said the main worry was children travelling to school during the downpour. Water had collected on several roads in and around Chennai, and parents were asked not to send children out unless the school had clearly said it was open.
“Wednesday’s holiday is a precaution for students. Parents should check the district administration’s announcement before sending children to school on Thursday.”
IMD says heavy rain can continue till October 26
The IMD has forecast heavy to very heavy rainfall at many places across Tamil Nadu, Puducherry and Karaikal in the coming days. The northeast monsoon is now active, and the wet spell is expected to continue till October 26.
According to the weather department, a low-pressure area is likely to form over the southwest Bay of Bengal near the Tamil Nadu coast. This system will push more rain into the state. The forecast also covers the Cauvery delta region and parts of southern Tamil Nadu.
The rainfall is expected to spread beyond the five districts where schools were closed. Places like Mayiladuthurai, Nagapattinam, Tiruvarur, Thanjavur, Erode, Dharmapuri, Krishnagiri and Salem may also get heavy showers. Students and parents in these areas should follow local district announcements closely, because holiday decisions can change from one district to another.
For the official forecast and weather warnings, track the updates on the IMD website.
What happens next: will the holiday extend?
So far, no holiday has been announced for October 22 or later. The closure orders apply only to Wednesday, October 21. Each district administration will look at the rainfall and the latest forecast before deciding whether schools open on Thursday.
This is how these decisions usually work: collectors review conditions early in the morning and issue fresh orders if needed. Families should not assume the holiday will continue. Check the district collector’s official notice or trusted local news before making plans.

What parents and students should do today
- Do not send children to school unless the district administration has clearly announced that schools are open.
- Avoid low-lying roads and flooded underpasses during the morning rush.
- Keep an eye on the IMD website for updated rain warnings in your district.
- Students with exams or submissions due should contact their schools for revised dates, because schools may announce changes after the rain clears.
If the rain continues, district collectors may extend the holiday. If the rain eases, schools will reopen on Thursday. Either way, the final word comes from your district administration.
