Tamil Nadu cyclone guide¶
Tamil Nadu has a long Bay of Bengal coast and receives much of its rain, and many of its cyclones, during the northeast monsoon from October to December. The state runs a State Control Room on the toll free number 1070, and each district collectorate runs a district emergency operations centre on 1077. The coast and low lying areas, including Chennai, are exposed to cyclone wind, storm surge, and flooding. Follow warnings from the India Meteorological Department and instructions from the state and your district collector.
