In Thoothukudi, continuous rainfall has affected urban and suburban areas, prompting the district administration to announce a holiday for schools. District Collector Vishu Mahajan announced the closure in view of the heavy rain. Meanwhile, mechanised boat fishermen in Thoothukudi have been advised not to venture into the sea for fishing due to continuous and heavy rainfall.
