On the morning of November 19, a depression over the southwest Bay of Bengal, off the north Tamil Nadu coast, moved between Puducherry and Chennai, according to the India Meteorological Department (IMD). Between 3 and 4 a.m., the depression hit the shore. As a result, the meteorological department has lifted the red alert in Chennai, indicating that the possibilities of really heavy rain are remote. However, the IMD has issued an orange alert for the city, suggesting very heavy rain and the need for authorities to be vigilant. According to IMD, the depression that was centred over north coastal Tamil Nadu and its surroundings at 5.30 a.m. on Friday, about 60 kilometres south-southwest of Chennai and 60 kilometres north-northeast of Puducherry, will continue to move west-northwestwards and weaken gradually into a well-marked low pressure area over the next 12 hours. Thunderstorms with light to moderate rain are expected to occur in various locations across Tamil Nadu and Puducherry over the next 24 hours, according to the weather department. During the same time period, heavy rain is expected in isolated areas across the Tamil Nadu districts of Krishnagiri, Dharmapuri, Vellore, Tirupattur, Erode, and Salem.
