CYCLONE AMPHAN THREAT TO THE EAST COAST, FINGERS CROSS FOR ANDHRA PRADESH, ODISHA, AND WEST BENGAL

The India Meteorological Department on Saturday predicted that the depression in Bay of Bengal is likely to intensify rapidly into a cyclonic storm in the next 12 hours and further into a severe cyclonic storm in subsequent 24 hours. 

Pursuant to that, cyclonic storm 'Amphan' is likely to move north-north-westwards initially till May 17 (Sunday) and then re-curve north-northeastwards across northwest Bay of Bengal towards West Bengal coast during May 18-20, said Ananda Das, Scientist at Regional Specialised Meteorological Centre. 

The weather department has warned of adverse weather in the Andaman Sea and along and off Andhra Pradesh, Odisha and West Bengal coasts for the next five-six days. The well marked low pressure area southeast Bay of Bengal has intensified into a depression. 

The system is centered around 10.6N and 87.3E, about 900km southeast of Visakhapatnam. 

The depression is moving northwest and remains in a favorable environment for further development. It is likely to become a cyclonic storm by tomorrow and reach abeam Chennai at a safe distance of approximately 600km. The storm thereafter will be moving initially north and then northnortheast (NNE) and strengthen further to a severe cyclonic storm. Extreme northern parts of coastal Odisha and West Bengal will run the risk of direct impact around 19th May.
