The month of July has seen a series of weather systems in the form of cyclonic circulations intensifying into low pressure areas and even into depressions at times. Now, the month of July is expected to an end with a system forming in the Bay of Bengal.
Currently, an upper air cyclonic circulation is seen around a broad area over Bangladesh and adjoining West Bengal. Now, the system is expected to become more organized in the coming days. In fact, the circulation is expected to become a low pressure area during the next two to three days over Northwest Bay of Bengal.

Due to the formation of the low, the Monsoon trough which usually has a tendency of shifting towards the foothills of Himalayas, is expected to be pulled back. Due to this, eastern parts of the country who have remained rain deficient for a long time are expected to receive some good rains.
Rains have been occurring over the states of West Bengal, Jharkhand, and Bihar for the last few days and with the arrival of a fresh low pressure area, rainfall activity is expected to witness an increase in the coming days. These rains may result in the reduction of rainfall deficiency over these areas.
