Orange Alert’ Issued
Heavy rainfall continued to lash Chennai and parts of Tamil Nadu on Wednesday morning, flooding roads, disrupting traffic, and prompting officials to shut down schools and colleges across several districts. The India Meteorological Department (IMD) has now issued a cyclone warning for coastal Tamil Nadu, with the state capital under an ‘orange alert’ and eight other districts under a red alert for extremely heavy rainfall.
“The weather system over the Bay of Bengal is likely to intensify into a depression today and may move toward the coasts of north Tamil Nadu, Puducherry, and south Andhra Pradesh,”
said B. Amudha, Director, Regional Meteorological Centre, Chennai.

🌧️ Tamil Nadu Braces for Intense Monsoon Showers
The ongoing northeast monsoon, which began early this year, has intensified due to a low-pressure system over the Bay of Bengal, approximately 400 km from the Chennai coast.
The IMD said the system is expected to strengthen into a depression by Wednesday noon and could bring widespread heavy rainfall, strong winds, and sea turbulence over the next 48 hours.
“The situation is being closely monitored. Fishermen are advised not to venture into the sea,” the IMD advisory said.
🏫 Schools, Colleges Shut in Multiple Districts
In light of the worsening weather, Chennai District Collector Rashmi Siddharth Zagade declared a holiday for all schools on Wednesday.
According to reports, colleges in Chennai will also remain closed, while offices are expected to function normally.
Several other district administrations — Cuddalore, Villupuram, Ranipet, Puducherry, and Karaikal — have also announced holidays for schools and colleges as a precautionary measure.
In Thoothukudi, however, only schools have been ordered shut.
