Current Situation
The southwest monsoon activity is likely to improve during current week as the axis of monsoon trough has shifted southward and currently lies near its normal position running to north Bay of Bengal.
An upper air cyclonic circulation lies over northwest Bay of Bengal and adjoining Gangetic West Bengal and north coastal Orissa, extending upto midtropospheric levels.
With the above scenario, fairly widespread rainfall with isolated heavy falls is likely over central and eastern India during next 2-3 days. The rainfall activity is also likely to increase over plains of northwest India and adjoining Rajasthan from 12th onwards for subsequent two to three days.
Updated Monsoon Forecast In view of prevailing rainfall scenario and inputs from statistical and
numerical weather prediction (NWP) models based on latest data, forecast of rainfall during the month of August is revised to 90% ( ± 9%) of normal against earlier forecast of 101% and seasonal forecast (June to September) is revised to 87% ( ± 4%).
