The warm pool of waters is making the depression in the West-Central Bay of Bengal (off Andhra Pradesh coast) to travel towards the Odisha coast.
The raised sea-surface temperatures that also aids convection (evaporation and cloud-building) will allow it to strengthen further into a deep depression, a India Met Department (IMD) has forecast.
HEAVY RAIN, HIGH WINDS
Meanwhile, the developing storm would bring heavy to very heavy rain over Coastal Odisha and heavy at isolated places over interior Odisha and North Coastal Andhra Pradesh today.
Heavy to very heavy rain is also forecast for Gangetic West Bengal and the North-Eastern States while thunderstorm and lightning is likely for a wide swathe of area in East and North-East India.
The area likely to be affected include Chhattisgarh, Jharkhand, North Coastal Andhra Pradesh, West Bengal, Assam, Meghalaya and the rest of the North-Eastern States.
Squally winds with speeds reaching 45- to 55 km/hr and gusting up to 65 km/hr are forecast along and of the North Andhra Pradesh, Odisha and West Bengal coasts.
Fishermen have been advised to not to venture out into the rough seas from the Andhra Pradesh, Odisha and West Bengal coasts today.
DRIFTING INTO NORTH-EAST
The forecast for tomorrow (Friday), soon after the cross-over of the deep depression, says that heavy to very heavy rainfall is likely along the Coastal Odisha and Gangetic West Bengal.
It will be heavy at isolated places over interior Odisha, Jharkhand, hills of Bengal, Assam, Meghalaya and the rest of the North-Eastern States.
Squally winds with wind speeds reaching 45- to 55 km/hr and gusting to 65 km/hr are forecast along and off the Odisha and West Bengal coasts with warning extended to fishermen for the second day.
Weakening in intensity on landfall, a remnant of the deep depression is forecast to plough its way into the North-Eastern states bringing varying amount of rain for the next couple of days.
It is the second storm close to cyclonic strength that is impacting the region in as many weeks. The first one too had brought with a heavy belt of heavy to very heavy rain.
Latest satellite pictures showed heavy clouding over along the Andhra Paradesh-Odisha coast from Narsapuram, Kakinada, Visakhapatnam, Vizianagaram, and Srikakulam into Brahmapura, Puri, Bhubaneswar and Bhadrak.
