Fishermen have been warned not to venture into the Gulf of Mannar and southwest of the Bay of Bengal, along and south of the coast of Tamil Nadu and north of Sri Lanka for the next 12 hours. They were also warned not to enter along and off the coast of Kerala, the Lakshadweep-Maldives area and the adjacent southeastern Arabian Sea for the next 24 hours.
IMD had previously predicted that Burevi, which crossed the coast of Sri Lanka on Wednesday night, would hit the coast of Tamil Nadu as a cyclonic storm. Deep depression is a stage of formation or disintegration of cyclones.
In the week ending December 2, Tamil Nadu had received a very large excess rainfall, registering 55 cm while its normal level is 25.3 cm. IMD has already issued a red alert for southern Tamil Nadu and southern Kerala.
