24% Excess Rain Recorded in August, Highest Since 1983

The India Meteorological Department (IMD) in its weekly weather update stated that this August recorded the highest rain 24% excess for the first time since 1983 when 24% excess rain was recorded. It was in 1926 when 33% of excess rain was recorded in August.

According to IMD, several parts of India, particularly central and some parts of western India including Gujarat and Rajasthan, recorded excess rain during the first three weeks of August. The week ending August 12 saw 13% excess, the week ending August 19 saw 42% excess, and the week ending August 26 saw 41% excess rain.

IMD, in its weekly weather update Friday, said there will be above average rain at least until September 3. Rainfall could reduce thereafter as no low-pressure area is likely to form over the Bay of Bengal until around September 10. Five low pressure areas have already formed in August, bringing extensive and heavy rain to east, central and west India. Low pressure areas are the main rain bearing systems during the monsoon. In the week ending August 26, for example, Hairamgarh in central India recorded 23 cm; Jodia in Gujarat recorded 34 cm; Bhungra in Rajasthan recorded 36 cm, all in the extremely heavy rain category (over 20 cm).

There is a well-marked low-pressure area over north Chhattisgarh and the adjoining east Madhya Pradesh. It is very likely to move west-north-westwards across north Madhya Pradesh and south Uttar Pradesh during the next two days and weaken gradually, IMD said in its Friday morning bulletin.

Overall monsoon rain is 8% excess with 23% excess rain over the south peninsula; 16% excess over central India; 12% deficient over northwest India and 4% excess over east and northeast India.
