Depression over Central Bay of Bengal (BoB) has intensified in to a deep depression. The depression moved north-northeast over East-Central BoB and is now centered around 18 degree North and 90 degree East, about 620km south-southeast of Kolkata. It is likely to move nearly northward and intensify to a tropical storm, by this evening.
Deep depression has manifested in the satellite imagery with sharp features, getting further refined. Tight circular bands of convective clouds are wrapped around the low level cyclonic circulation, with decent outflow. Environmental conditions are favourable for rapid intensification. Sea surface temperature of 30-31 degree and moderate wind shear is supportive enough for further intensification. The system has high potential to intensify in to a cyclonic storm in the next about 12 hours.
The cyclone will head for Bangladesh, moving close to Sunderban Delta and Sagar Islands. The storm will strengthen further to gain severity and cross Bangladesh coast near Khepupara, as severe cyclonic storm, tomorrow evening/night.
The storm is not likely to impact the coastline of Andhra Pradesh and Odisha with adverse weather conditions. However, overcast sky, moderately strong winds, intermittent moderate rainfall will be the highlights. As the storm moves closer, the Delta area and coastline of Gangetic West Bengal will have overcast sky, embedded with thunderstorm. Heavy rainfall and strong winds are likely in that region. Post landfall, the inclement weather conditions are likely for northeast India for subsequent 48 hours. Exercise caution and remain in state of preparedness to meet any eventuality, at short notice.
