According to the Met Office, the deep depression that had been over north Odisha and the adjoining Gangetic West Bengal coastal area has moved westwards and now lies over north Odisha, southern Jharkhand and Chhattisgarh. It is expected to weaken gradually as it continues moving west.
The extended axis of the monsoon trough stretches from Rajasthan through Madhya Pradesh, the centre of the deep depression and the southern part of Bangladesh to Assam. The monsoon remains fairly active over Bangladesh and is moderate to strong over the North Bay of Bengal.
