The monsoon depression over the Northwest Bay and adjoining Odisha–West Bengal coasts has intensified into a deep depression.
It is expected to move north‑northwest and cross the West Bengal–north Odisha coasts by Monday evening.

Under its influence, squally weather may affect Bangladesh’s maritime ports, the North Bay, and adjoining coastal areas. Maximum sustained wind speed within 48 km of the centre is about 50 kph, rising to 60 kph in gusts. The sea will remain rough near the depression.
