An extended rainy spell with wide spread showers are likely over Odisha and Chhattisgarh. Both the states are expected to witness moderate rainfall at many places and heavy rainfall at few places between 20th and 26th July. Fairly widespread vigorous monsoon activity is likely between 21st and 23rd July. Light rainfall at most places and moderate showers for few places will continue even during later days of the month.
Presently, a cyclonic circulation is marked over tri junction of Jharkhand, Chhattisgarh and Odisha. This is likely to meander over the region for the next 2-3 days. This system will move over Southwest Madhya Pradesh and neighboring Rajasthan and Gujarat on 23rd July. On the same day, another small scale circulation will appear over Coastal Odisha and Northwest Bay of Bengal. This feature also will stay over the area for about 24 hours and move inland as a weak system on 26th July. An east-west trough joining the above 2 systems will run through the states of Chhattisgarh and Odisha.
Rain and thundershowers accompanied with lightening and squally winds are likely over both the states between 21st and 23rd July. Interiors of Odisha will be more vulnerable for intense weather activity. From 27th to 30th July, the intensity of weather activity will reduce over the contiguous states.
Both the states remained deficit in June, on account of weak monsoon and slow progress. However, formation of low pressure area and cyclonic circulations in July recovered the deficiency. Both the states are marginally above the average rainfall, as of now. The upcoming wet spell will increase this margin over the next one week. Paddy growing bowl of India will witness adequate rains now, to overcome the earlier loss and sustain growth.
