The resident low-pressure area over Uttar Pradesh seems to have ‘blinked first’ in a fascinating duel with a brewing successor to assume charge of the monsoon proceedings.

This is expected to make the way clear for the latter to prosper in the Bay of Bengal, with a preparatory upper air cyclonic circulation having been hoisted already over the east Bay.

Successor system

India Meteorological Department expected this circulation to descend into the appropriate levels to settle as the next low-pressure area.

This ceding of pole position in the monsoon schemes of things also ensures orderly transition from one monsoon ‘pulse’ to the other.

The brewing ‘low’ is a remnant of typhoon Rammasun that emptied itself in successive landfalls over Hainan Island and, as recent as this morning, the China-Vietnam border.

Under the combined impact of the two ‘low’s, a broad corridor of heavy to very heavy rainfall would be carved out over central India, right from east to west, this week.

A ‘tongue’ of this heavy rainfall regime will extend into south Gujarat, Saurashtra, Mumbai-Konkan and into coastal Karnataka.

Rains to return

This would mean that heavy rains may continue to haunt Mumbai, Surat, Vadodara, Rajkot, Ahmedabad and even Gandhinagar.

According to the US Climate Prediction Centre, another wave of rainfall but lesser in intensity would steer towards from central India to north India from July 25 to 31.

Even here, a footprint of isolated very heavy rain is forecast to leave its imprint over Odhisha, Jharkhand and west Uttar Pradesh.

Meanwhile, India Met Department said this afternoon that thundershowers lashed most places in Himachal Pradesh, Uttarakhand, Uttar Pradesh, Madhya Pradesh, Chhattisgarh, east Gujarat, Konkan, Goa, Madhya Maharashtra and Kerala during the 24 hours ending this morning.

A similar outlook has been forecast for the next two days for Uttar Pradesh, north coastal Andhra Pradesh, east Madhya Pradesh, Chhattisgarh, Telangana and Karnataka.
