Cyclonic storm ‘Nilam’ on Tuesday brought heavy rains in several parts of North Tamil Nadu, affecting normal life.
As the deep depression in the Bay of Bengal intensified into the cyclone and remained practically stationary, centred at about 450 kms south-southeast of Chennai and 130 kms north-northeast of Trincomalee in Sri Lanka, the city and several parts of the state experienced incessant rains since morning.
The storm is expected to cross the coast between Cuddalore in the state and Nellore in Andhra Pradesh tomorrow.
“Squally wind speed reaching 45-55 kmph gusting to 65 kmph would prevail along and off north Tamil Nadu, Puducherry and adjoining south Andhra Pradesh coasts during next 12 hours,” the weather office said, adding that wind speed would gradually increase as the system comes closer to the coast.
Sea condition will be very rough to high along and off north Tamil Nadu, Puducherry and adjoining south Andhra Pradesh coasts during the next 48 hours. Fishers in these areas have been advised not to venture into the sea.
The weather office also forecast storm surge of about 1-1.5 metres over the astronomical tide which is likely to inundate low-lying areas of Chennai, Kancheepuram and Tiruvallur in Tamil Nadu and Nellore district of AP.
Danger signals ranging between three to seven have been hoisted in ports in Chennai and elsewhere in the state, it said.
