Schools Shut in Tamil Nadu Districts
Schools in three Tamil Nadu districts remained closed on Thursday, October 16, 2025, due to heavy rainfall triggered by the onset of the northeast monsoon. District Collectors of Tirunelveli, Tenkasi, and Thoothukudi declared school holidays after continuous downpours caused waterlogging in paddy fields and roads, disrupting normal activities. However, as of October 17, no official announcement has been made regarding school closures for Friday, despite persistent rain alerts.
The India Meteorological Department has issued an orange alert for heavy to very heavy rainfall in multiple districts, including Sivaganga, Ramanathapuram, Madurai, Virudhunagar, Thoothukudi, Tirunelveli, Kanyakumari, and Tenkasi, on Friday. An IMD heavy rain alert in Tamil Nadu warns of rainfall ranging from 7 cm to 20 cm at isolated places, accompanied by thunderstorms and gusty winds reaching 30-40 kmph.

Northeast Monsoon Impact
The northeast monsoon officially commenced over Tamil Nadu, Puducherry, and Karaikal on October 16, 2025, bringing widespread rainfall activity. Tamil Nadu weather update confirms that Thiruchendur in Thoothukudi registered the highest rainfall at 146 mm on Thursday, while several other areas recorded over 100 mm of precipitation. The Nambiar River has swollen due to runoff from the Western Ghats, leading to flooding concerns in southern districts.
The IMD has advised fishermen not to venture into the sea, warning of squally weather with wind speeds reaching 35-45 kmph, gusting up to 55 kmph along the Tamil Nadu coast, Gulf of Mannar, and Comorin area. Parents and students are advised to monitor official district administration announcements regarding potential school closures and follow safety instructions during this active monsoon period.
