Chennai, the capital city of Tamil Nadu, witnessed heavy rainfall throughout Sunday, causing waterlogging and disruption in flight operations. The state government declared a holiday for schools in Chennai and six other districts on Monday, 19 June, in view of the inclement weather.
According to the Regional Meteorological Department, Chennai recorded moderate thunderstorm with moderate rain in isolated places on Monday morning. The department also issued a yellow alert for Chennai and other coastal districts for the next two days, indicating heavy rain at isolated places.
The heavy rain was caused by a low-pressure area over the Bay of Bengal, which is likely to intensify into a depression by Tuesday. The low-pressure area is expected to move west-northwestwards and cross north Tamil Nadu coast between Nagapattinam and Chennai by Tuesday evening.
The rain also affected the international flight operations at the Chennai International Airport on Sunday night. Ten incoming flights, including those from Doha and Dubai, were diverted to Bengaluru due to poor visibility and waterlogging on the runway.
The authorities have advised the public to refrain from unnecessary outings, particularly in low-lying areas, and to remain vigilant for potential mudslides and landslides. The civic body has deployed teams to clear waterlogged roads and drains and restore power supply in affected areas.
Meanwhile, around 70 people were injured in a collision between two private buses in Melpattampakkam of Cuddalore district of Tamil Nadu on Monday morning. The injured were taken to Cuddalore government hospital for treatment.
