Cyclone Murasu, which intensified into a severe cyclonic storm over the west-central Bay of Bengal, is likely to cross the south Andhra Pradesh coast between Nellore and Narsapur, south of Ongole, from Monday midnight to the early hours of Tuesday. The cyclone may bring heavy rainfall to Tamil Nadu, particularly Chennai and its neighbouring districts.
The system is expected to make landfall as a severe cyclonic storm with wind speeds of 100-110 kmph, gusting to 120 kmph. After landfall, it is likely to continue moving west-northwestwards, weakening into a cyclonic storm by Tuesday morning, a deep depression by Tuesday night, and a depression by Wednesday.
The storm is expected to spare Tamil Nadu from a direct landfall but its influence will bring widespread rainfall, particularly over northern districts. Chennai and Tiruvallur have been receiving heavy to very heavy rainfall over the last two days.
As per the rainfall received in last 24 hours ending 8.30 am on Monday, Chennai had already received substantial rainfall, with Kadapakkam and Parrys recording 15 cm each, followed by Manali New Town and Manali with 14 cm each.
