A low pressure area is forming over the North Andaman Sea within next 48 hours and rapidly intensifying to a depression over the East Central Bay of Bengal in the subsequent 24 hours. The weather system will move west-northwest and reach North Coastal Andhra Pradesh and South Odisha Coast in the early hours of 11th October and later move across Telangana and Maharashtra.
The depression may weaken to a well marked low pressure after crossing the coast and later reduce to just a cyclonic circulation over North Maharashtra. The peripheral reach of the system will affect Madhya Pradesh, North Karnataka and Gujarat. One week life cycle of this system will impact Central and South India (Odisha, Andhra Pradesh, Telangana, Maharashtra, Madhya Pradesh, Chhattisgarh, Gujarat, Karnataka).
Heavy to very heavy rainfall is expected over few places in Andhra Pradesh, Telangana and Maharashtra. Thunderstorms accompanied with lightning and strong wind is expected to accompany this weather activity over a large area. The remnant of the earlier weather system over Andhra Pradesh and Odisha is likely to be subsumed by this depression. Light to moderate rains is expected over parts of Uttar Pradesh, Bihar, Jharkhand, and Chhattisgarh. Delhi NCR may experience partly cloudy sky on 12th-13th October.
In the wake of this depression, another few weather systems are waiting in the wings to track a similar path in quick succession. Accordingly, the further withdrawal of southwest monsoon may pause for some time. However northern parts of the country will remain dry except parts of East Rajasthan and West Uttar Pradesh.
