New Delhi: In another boost to the southwest monsoon, a fresh low pressure area is developing over Bay of Bengal, which could bring heavy rainfall over Central India in the next few days.

In its forecast, the India Meteorological Department (IMD) said a fresh low pressure area was located over north-west Bay of Bengal, adjoining West Bengal coast early Monday. It is likely to move west-north-westwards and become more marked over the next two days.

Low pressure areas strengthen the monsoon current and are associated with increased rainfall activity as they progress over the land. It is the second low-pressure system to have formed in last one week, driving the monsoon current.

Under its influence, heavy rainfall of over 20.4 cm is expected over Odisha, Vidarbha, Chhattisgarh, and Madhya Pradesh during the next two days.

East Rajasthan would also receive increased rainfall on 14-15 August. The weather department has issued a red warning, urging to take action in the core monsoon region of Madhya Pradesh and East Rajasthan where extremely heavy rainfall is forecast.

In the south, Kerala which has been struggling with floods, due to incessant heavy rains over the last few days, could continue to receive moderate showers until Tuesday, after which the rainfall activity will likely ease. Parts of coastal Karnataka, Konkan and Goa are also likely to witness heavy falls over isolated places during the period.

Heavy rainfall during the last one week has managed to wipe out the deficit, with the country having received 1% above normal rains at 553 mm rainfall so far in the June-September season.

In its second long-range forecast for August and September, IMD forecast a 45% probability of monsoon to be at 100% of the long-period average of 89 cm with a model error of +/-8%. Rainfall between 94% and 106% of LPA is considered normal.
