Chennai. The weather department has doused a cyclone alert for north Tamil Nadu and south coastal Andhra Pradesh.
The upsurge has been detected at an area in the Bay of Bengal about 90 km east of Chennai, said officials, and the system is expected to be intensified into a cyclone in 24 to 48 hours. The wind speed is supposed to reach 75 km per hour.
"The system is likely to move northwest towards north Tamil Nadu, south Andhra Pradesh coast and may further intensify into a deep depression during next 24 hours. The system is likely to be close to Chennai during early hours of 18 May. It will move northwards and then recurve north northeastwards and may intensify into a cyclonic storm during subsequent 24 hours," it said.
Very heavy rainfall forecasted in Chennai and parts of Tamil Nadu and also in Puducherry.
The IMD advised fishermen not to risk into the sea as sea condition is likely to be rough along and off coastal Andhra, Puducherry and north Tamil Nadu.
The depression in the Bay of Bengal has caused heavy rain in Chennai in peak summer.
