The cumulative rainfall deficiency in the country has come down to 9% after remaining stagnant at 10% for the last couple of days. All thanks to the Monsoon trough, which has brought exceptionally heavy rains in Northeast India. The trough has moved north of its original position and shifted closer to the foothills of the Himalayas.
Southwest Monsoon has been vigorous over Assam and Meghalaya for the last few days. Active Monsoon conditions are being witnessed over Bihar, Sub-Himalayan West Bengal, Sikkim, Arunachal Pradesh, Nagaland, Manipur, Mizoram and Tripura. South Interior Karnataka and Kerala have also been receiving good amounts of rainfall. Hence, rainfall in these parts during last few days has contributed towards bringing the countrywide rainfall deficiency down.

At present, Monsoon is subdued over North and Central India. We have to wait for a fresh weather system to come up in the Bay of Bengal for Monsoon to revive in Central parts of the country.
