A depression over Jharkhand and adjoining West Bengal is set to bring rains over eastern India in the next couple of days, in what could bring down the small overall deficit in monsoon rains further, according to the country’s official weather forecaster.

“Heavy rainfalls would occur over Jharkhand, Odisha and Chhattisgarh during the next 48 hours,” India Meteorological Department (IMD) said in a statement. It also predicted heavy rainfalls over east Madhya Pradesh, Chhattisgarh, Vidarbha, Uttarkhand, east UP, west Madhya Pradesh and West Bengal over the next few days.

According to the IMD, the quantum of average monsoon rainfall across the country between June 1 and August 2 had been 443.8 mm, which was 6% less than the benchmark of 471.8 mm arrived at on the basis of a 50-year average shower. However, the regional distribution of rainfall so far has been uneven.

The north-west region, consisting of key states including Punjab, Haryana, UP and Rajasthan, received 9% excess rainfall than normal while central India region consisting of states such as Chhattisgarh, Madhya Pradesh, Maharashtra and Gujarat received 6% less rainfall than normal.

The southern peninsula has received 21% less rainfall than normal; Rayalaseema (34% deficiency) and north Karnataka (45% deficiency) are the worst affected. The eastern and north-eastern regions have received 7% less rainfall than normal with Bihar receiving 29% less rainfall than normal.

Meanwhile, private weather forecaster Skymet has said “after a dry spell of almost three to four days, the weather in the plains of north India is expected to change. Several places in Punjab, Haryana, Delhi and Uttar Pradesh will receive good rains between during the first week of August,”.

The IMD in June had revised downward its forecast of seasonal rainfall (June-September) for this year to 88% of the long-period average (LPA), from 93% reported in May. Skymet last week revised its forecast with showers at 98% of the LPA, calculated on the basis of average annual rainfall recorded between 1951 and 2000 (89 cm).

During the last one week, the central region received excess rain due to the deep depression over Gujarat, south Rajasthan, and west Madhya Pradesh. The heavy rainfall witnessed over the central region reduced rainfall deficiency to only 6% till Sunday from 10% deficiency from the normal benchmark a week back.
