Under the influence of persistent cyclonic circulation, a low-pressure area formed, last night over the Northwest and adjoining West-Central Bay of Bengal (BoB). The cyclonic circulation associated with low is largely tilting southwestward with height. It has dragged the cloud cluster over BoB, far to the south of the centre of the system. The low pressure will stay over the ocean for the next 2-3 days. The system will have tendency to shift along the coastline to position over ‘Head Bay’ by 09th September. It may even intensify to a well-marked low or depression during this period.
The proximity of the system to the coastline will trigger moderate to heavy rains over parts of Odisha, Coastal Andhra Pradesh, Telangana and Chhattisgarh, today and tomorrow. The weather belt will extend and reach parts of Jharkhand, Bihar and West Bengal, in the subsequent 48 hours.
In the meantime, the remnants of typhoon Yagi, in the South China Sea may travel across Vietnam, Laos and Myanmar and join up with the monsoon depression over the Bay of Bengal. The process of unification will add more power to the coupled system. The spread and intensity of the weather will increase manifold. Northeast India, Bangladesh and the eastern states of West Bengal, Bihar and Jharkhand will be at risk of bracing fury of the system.
The weather activity will travel further across the central parts. Since, the model accuracy goes low, after a lead time of about 5 days, a fresh call needs to be taken, to ascertain the scale and extent of weather activity. Both, the monsoon system in BoB and typhoon Yagi will be kept under close observation, to predict the track, timelines and extent of monsoon fury.
