Cyclonic circulations over Haryana and Coastal Andhra Pradesh became hyperactive overnight, delivering heavy to very heavy rainfall into Wednesday morning. Both persisted into the evening, an update by the India Meteorology Department said, with scattered rain indicated for both regions for a day or two.

The spurt marks the end of August, a month in which the monsoon was mostly indifferent to the peninsula and the North-East while being benevolent to North-West and Central India.

Rainfall for the country as a whole during the season is in deficit at -3 per cent.

North-West India and Central India have continued to hold on to their single-digit surpluses.

The monsoon is preparing to leave West Rajasthan in what is normally a month-long process of withdrawing from mainland India, where it has been in operation from June 8.

Global models indicate East India will stop the withdrawal line from entering the region for sometime with a rain-generating low-pressure area expected over the North Bay of Bengal.

‘Buzz’ to continue

The US National Centre for Environmental Prediction is of the view that the withdrawal line may instead push into West India (Gujarat and West Madhya Pradesh) during this period.

A tracker model featured by the US Climate Prediction Centre said that the ‘buzz’ around the North Andhra Pradesh coast would continue into the first two weeks of September.

Rain deficit

Meanwhile, the monsoon flare-up over Rayalaseema and Telengana has helped to bring down the rain deficit from -12 per cent on Tuesday to -10 per cent on Wednesday.

The deficit in the East and North-East has also seen some improvement, dipping from -19 per cent to -18 per cent during this phase.
