The India Meteorological Department (IMD) has said that a depression over the South-east Bay of Bengal has moved west-northwestwards and intensified into a Deep Depression. It lay centred over the Southeast and adjoining Southwest Bay of Bengal and about 700 kilometres east-southeast of Chennai in Tamil Nadu and 770 kilometres south-southeast of Visakhapatnam in Andhra Pradesh. IMD said it is very likely to move west-northwestwards and intensify into a Cyclonic Storm over the southwest and adjoining West-central Bay of Bengal during the next six hours and into a Severe Cyclonic Storm by tomorrow. It is very likely to cross the southern Andhra Pradesh coast as a Severe Cyclonic Storm with wind speed of 100 to 110 kilometres per hour, gusting to 120 kilometres per hour between Nellore and Narsapur by Tuesday morning.
