An anticipated low-pressure area formed over the North-West Bay of Bengal on Monday, which the India Met Department (IMD) expects to become ‘more marked’ (an initial round of intensification) and boost the monsoon system as a whole.

Its impact will unfold as it moves in a typical West-North-West track to cover East India, Central India, West India and North-West India in what would be a productive session.

Heavy rains seen

The IMD has forecast widespread rainfall with isolated heavy to very heavy falls over Bengal into Tuesday and over Odisha and Jharkhand into Wednesday.

Fairly widespread to widespread rainfall has been forecast for Chhattisgarh on Tuesday and Wednesday; over Madhya Pradesh from Tuesday to Thursday; and over Rajasthan and Gujarat from Wednesday to Friday.

The IMD has warned that strengthening of low-level monsoon westerly winds (from the Arabian Sea) may bring widespread rainfall with isolated heavy to very heavy falls along the West Coast and the Ghat areas during the next three days.

Along with this, the convergence of monsoon easterlies from the Bay could trigger fairly widespread to widespread rainfall with isolated heavy to very heavy falls over the Western Himalayas and adjoining plains of North-West India during the next two days.

‘Much steam left’

Earlier on Monday, an ensemble outlook from the US National Weather Services had said that the Indian monsoon has quite some steam left, and will stay active until August 22.

In fact, it will witness another busy session from August 14 as a productive Bay of Bengal sends in cyclonic circulations/low-pressure areas to East, Central and adjoining North-West India.

This would largely be the trend going into August 22, up to which information is available, according to the US agency. A circulation may pop up even over South Andhra Pradesh by August 18.

Some of these rains could help lift the spirits up in the Rayalaseema subdivision, where the rain deficit has shot up to -41 per cent.
