After heavy rainfall in east and northeast India in the last week of July, the monsoon has subsided in the region, though rainfall activity has intensified once again in the central and northwest parts of the country.

This has resulted in a marked improvement in the flood situation in Assam and Meghalaya, and also in Bihar. Some rivers in Bihar and Uttar Pradesh, however, continue to flow above the danger mark at some places.

In the last week, up to Friday, the country as a whole had received 6 per cent above normal rainfall, most of it in the western part of the country, barring Punjab and Kerala. Western UP, Rajasthan, Gujarat, western Madhya Pradesh, Maharashtra, Goa, almost the entire state of Karnataka and even Tamil Nadu, received above normal rainfall. Many parts of Maharashtra, including Mumbai, have been receiving heavy rain, with some places getting more than 20 cm rainfall in a day.

Out of the 890 mm of rainfall that is expected during the entire season, the country had received about 510 mm till the first week of August.

Northwest India received 26 per cent more than normal rainfall, while central India had 20 per cent above normal rain. Out of the 36 meteorological divisions in the country, 25 received rainfall that was normal or above normal.

Rainfall over the country as a whole from the start of the season, on June 1, has been 2 per cent above normal.

Earlier this week, the India Meteorological Department issued a forecast for August and September, in which it predicted a rainier second half of the monsoon. It said August and September were together likely to have rainfall that was 7 per cent above normal.

Northeast India which has had a relatively dry week is likely to start receiving rains from the second half of the coming week. Sikkim and West Bengal are also likely to have rains during this time, the IMD said.

The western half of the country, from north to south, is likely to continue getting good rains on Sunday, Monday and Tuesday. The country was receiving good rains despite large scale weather features not being very favourable. A negative Indian Ocean Dipole continues to prevail, while the Madden Julian Oscillation has weakened. The El Nino phenomenon in the equatorial Pacific Ocean is in neutral condition.
