In an update issued around 12 noon, the weather department said the deep depression was centered about 310 km southeast of Trincomalee, 710 km south-southeast of Puducherry, and 800 km south-southeast of Chennai as of 8.30 am on Tuesday.
“It is very likely to continue moving north-northwestwards and intensify further into a cyclonic storm on November 27. Thereafter, it will continue to move north-northwestwards towards the Tamil Nadu
coast, skirting the Sri Lanka coast during the subsequent two days,” the IMD said.
The IMD has predicted heavy to extremely heavy rainfall over Tamil Nadu, Puducherry, and Andhra Pradesh between November 27 and 29. Strong winds, ranging between 45-55 km/h with gusts up to 65 km/h, are likely along the affected coasts. Additionally, rough seas may lead to flooding in low-lying areas and disrupt marine activities.
Chennai and nearby districts of Chengelpet, Kanchipuram and Tiruvallur, the northern coastal city of Cuddalore and Cauvery delta areas, including Nagapattinam were among the places that received rainfall, which was mild to moderate in many areas and heavy in a few places.
Two NDRF teams have been dispatched to Thanjavur district. For each of the districts of Tiruvarur, Mayiladuthurai, Nagappatinam and Cuddalore, two teams — one from NDRF and the other from the State — have been dispatched.
