On the morning of October 22, 2025, the monsoon‑season downpour forced authorities in southern India to pull the plug on classrooms, colleges and even some private institutes. The move, announced by the District Collector of Chennai and backed by the chief minister’s emergency briefing, left roughly 10 million students stranded at home as rain battered the coast with unprecedented intensity.
When M.K. Stalin, Chief Minister of Tamil Nadu called a video conference at 9:15 AM IST with all district collectors, the agenda was clear: shut schools, ready relief camps, and mobilise heavy‑duty equipment before the water turned streets into rivers. At the same time, the India Meteorological Department (IMD) had already issued a red alert for eight districts, forecasting more than 20 cm of rain in a single day.
Background: Monsoon Season and Weather Alerts
The northeast monsoon that sweeps over Tamil Nadu every October is normally a welcome source of water for crops. This year, however, an erratic cyclonic circulation over the Bay of Bengal amplified the system, pushing moisture inland at record rates. The Regional Meteorological Centre (RMC) in Chennai warned that the entire north‑coastal belt could see "extremely heavy" rainfall, a phrase the agency reserves for events that break regional records.
Red alerts were slotted for Villupuram, Cuddalore, Mayiladuthurai, and six other districts. Orange alerts covered a broader swathe, including the state capital Chennai and the coastal stretch down to Kanyakumari.
Government Response: school closures and Flood Preparedness
At 10:30 AM UTC, Rashmi Siddarth Jagade, Chennai District Collector declared, "All schools will remain closed on Oct 22 due to continuous heavy rainfall," a statement echoed across every district under the red and orange alerts.
The Tamil Nadu Government followed a standard disaster‑management protocol: it ordered the setup of temporary relief camps stocked with food, drinking water and medicines. In villages near Sivaganga, JCB excavators and motor pumps were dispatched to clear blocked canals, while boats and trucks were pre‑positioned for swift evacuation if waters rose further.
Meanwhile, the Puducherry Government mirrored the directives, closing every government‑run and private school in the union territory, including the enclave of Karaikal. The move was prompted by a parallel red alert issued by the IMD for the region.
On‑the‑Ground Impact: Communities and Transportation
Residents of the Choolaimedu neighbourhood in Chennai woke up to uprooted trees and streets turning into shallow streams. In Thoothukudi, waterlogged roads left emergency vehicles scrambling for higher ground. Farmers in the low‑lying fields of Sivaganga saw their crops submerged, a loss that could dent the district’s rice output for the season.
Transportation snarled badly. At the central bus stand in Villupuram, dozens of buses were stranded as water rushed onto the platform, leaving passengers with no choice but to wade through ankle‑deep pools. Similar disruptions were reported in Chennai’s suburban rail network, where several services were suspended until the tracks dried.
The National Disaster Response Force stepped up its presence, adding 12 teams to the existing 16 in the high‑risk zones. By the end of the day, a total of 28 NDRF units were on standby, equipped with inflatable boats, life‑vests, and portable generators.
Expert Commentary and Future Outlook
Meteorologists from the IMD cautioned that while the cyclonic system might intensify, “it is unlikely to develop into a full‑blown cyclone,” according to a Times of India roundup. Still, they projected another 10‑15 cm of rain across Chennai and the adjoining districts on October 23‑24, meaning floodwaters could linger for days.
Disaster‑management expert Dr. Anitha Ramesh of the Indian Institute of Public Administration noted that the quick issuance of red alerts likely saved lives. “When authorities act decisively—shutting schools, pre‑positioning equipment—they give communities a buffer,” she said, adding that continuous monitoring will be crucial as the monsoon stalls.
Looking ahead, the state plans to review its academic calendar. Officials hinted that the missed school day may be compensated with extended summer sessions, a move that could affect board‑exam preparations for thousands of students.

Frequently Asked Questions
How does this affect students in Tamil Nadu and Puducherry?
The closures suspend regular classes for roughly 10 million pupils, pushing schools to shift the missed syllabus to later in the term. Many private tutoring centres have already announced online sessions to keep learning momentum, while state boards are reviewing exam timelines to accommodate the lost day.
What led to the decision to shut schools on October 22?
A combination of IMD’s red‑alert warnings, projected rainfall exceeding 20 cm, and rising water levels in coastal districts prompted officials to prioritize safety. The District Collector of Chennai publicly announced the closures after confirming that road and bridge conditions were deteriorating rapidly.
Which districts are under the red alert, and what does it mean?
Red alerts cover Villupuram, Cuddalore, Mayiladuthurai, Nagapattinam, Tiruvallur, Thanjavur, Pudukottai and Ramanathapuram in Tamil Nadu, as well as the Union Territory of Puducherry. The designation signals extremely heavy rainfall—typically more than 20 cm in 24 hours—requiring immediate precautionary measures like school closures and evacuation planning.
What is the weather forecast for the next few days?
Meteorologists expect another 10‑15 cm of rain across the north‑coastal belt on October 23‑24, with the possibility of localized thunderstorms. While the cyclonic system may weaken slightly, the soil saturation levels are already high, so flooding could persist despite a temporary lull in precipitation.
How are relief efforts being coordinated across the affected regions?
Relief operations are overseen by the state disaster management authority, with the NDRF supplying teams and equipment. Temporary shelters have been opened in schools outside the red‑alert zones, each equipped with generators, drinking water tanks and medical kits. Local NGOs are also mobilising volunteers to distribute dry rations to stranded families.
