THIRUVANANTHAPURAM: Cyclone Burevi has weakened into a deep depression and will cross the Tamil Nadu coast on the morning of December 4, the India Meteorological Department (IMD) said on Thursday.

"Cyclonic storm Burevi over Gulf of Mannar weakened into a deep depression on 3rd December and is close to Ramanathapuram district coast, about 20 kilometres southwest of Pamban and 210 km east-northeast of Kanyakumari," the Cyclone Warning Division of the IMD said this evening.

The deep depression would move west-southwestwards and cross Ramanathapuram and Thoothukudi districts between Thursday night and Friday early morning with a wind speed of 50-60 kmph, gusting up to 70 kmph.

Meanwhile, the Kerala government has announced a public holiday for 5 districts in the state on Friday as the state braces for heavy rain expected when Cyclone Burevi makes landfall. The districts are Thiruvananthapuram, Kollam, Pathanamthitta, Alappuzha and Idukki. Offices, including public sector undertakings, have also been given leave. The holiday is not applicable to disaster relief, essential services and election duties.
