The Hindu Business Line : ‘Low’ active over west, central India

Thiruvananthapuram, Aug 21 The west-northwest-bound monsoon ‘low’ drifting in from the Bay of Bengal was located to east Madhya Pradesh on Tuesday powering rain into adjoining west and central India.

Though much weaker than its hyperactive predecessors, the system is still expected to drive widespread rainfall with scattered heavy to very heavy falls over west Madhya Pradesh and Gujarat over the next two days, an update from the India Meteorological Department said.

Fairly widespread rainfall with isolated heavy to very heavy rainfall is also likely over east Madhya Pradesh during the next 24 hours and over Saurashtra, Kutch and south Rajasthan during the next two days.

WET OVER WEST COAST

The offshore trough to the southwest has become accentuated once again, which is predicted to lead to fairly widespread rainfall with isolated heavy to very heavy falls over Konkan, Goa, coastal Karnataka and Kerala during the next three days.

On Tuesday, the axis of the monsoon trough passed through Phalodi, Guna, the centre of the land-based low-pressure area, Chaibasa, Balasore and southeastwards to east-central Bay of Bengal.

Going forward, the European Centre for Medium-Range Weather Forecasting does not see a major monsoon ‘low’ emerging from the Bay of Bengal at least during the course of the week. Flows over the Arabian Sea will also remain subdued.

But the US National Centres for Environmental Prediction is of the view that the week ending August 28 (Tuesday next) will see progressively more rain getting accumulated to the south-southwest of the country (coastal Karnataka, Kerala and the peninsular tip).

MORE RAINS LIKELY

The following week will be marked by a burst of rain over Gangetic West Bengal probably under the influence of an easterly wave, which will propagate further west dropping varying amounts of rain over east-central and adjoining central India. It will culminate in a blow-up over the south Gujarat-north Konkan-Mumbai region around August 28.

The high-pressure region in the west Pacific that triggered a heat wave in Japan and other parts in the far northeast is in the process of lifting slowly.
