Cyclone Burevi is likely to emerge into the Gulf of Mannar and the adjoining Comorin area on Thursday morning, after crossing the Sri Lankan coast on Wednesday evening/night. It may largely impact the southern parts of the State and bring fairly widespread rain till Saturday, according to the India Meteorological Department (IMD).
It is likely to cross south Tamil Nadu, between Kanniyakumari and Pamban, early on Friday morning. As on Tuesday, the cyclone, forecast to reach the Sri Lankan coast, moved westwards, with a speed of 13 kmph.
The IMD has provided a yellow alert, updating the authorities on the approaching weather disturbance.
Officials of the Meteorological Department said extremely heavy rain (above 24 cm) was likely, in one or two places over south Tamil Nadu, including Tirunelveli, Thoothukudi, Kanniyakumari and Ramanathapuram, on Wednesday and Thursday.
Other southern districts may experience isolated, heavy to very heavy rain around the same time. However, the intensity of rainfall may drop after December 4.
