New Delhi (NVI): A fresh low-pressure area is very likely to form over the north Andaman Sea and adjoining east central Bay of Bengal around Friday, that may lead to heavy rains in coastal areas of Odisha and Andhra Pradesh.

“It is very likely to move north-westwards towards north Andhra Pradesh and Odisha coasts with gradual intensification into a depression during subsequent 2-3 days,” according to the Cyclone Warning Division of the India Meteorological Department (IMD).

The current Low Pressure Area lies over northwest Bay of Bengal and adjoining Odisha coast. It is very likely to persist there till 5 October and become less marked thereafter. However, its associated cyclonic circulation is very likely to move over to south Chhattisgarh on 6th October and remain active till 7th October, the IMD said.

Under the low pressure effect, light to moderate rainfall at most places with heavy (6.5-12 cm) to very heavy (12-20 cm) rainfall at isolated places would occur over Andaman and Nicobar Islands on 9th and 10th October, the weatherman said.

Under the influence of current Low Pressure Area over northwest Bay of Bengal and adjoining Odisha coast, fairly widespread to widespread rainfall very likely over Odisha, Bihar, Jharkhand, Gangetic West Bengal during next 4 days.

Isolated heavy rainfall is very likely over Odisha during October 4-6, Jharkhand on October 4, 6 and 7, over Bihar on 6 and 7 October, Chhattisgarh from 4 to 7 October, the IMD said.

Under the influence of fresh Low Pressure Area, rainfall activity is very likely to increase over Odisha and coastal Andhra Pradesh during 11th to 13th October, the Meteorological Department added.

Squally wind speed reaching 40-50 kmph would prevail of north Andaman Sea, East central and adjoining southeast Bay of Bengal on 9th and 10th October; 50-60 kmph over central Bay of Bengal on 10th and 11th October and over north Coastal Andhra Pradesh and Odisha coasts and adjoining North Bay of Bengal on 11th October.

The IMD further stated that sea condition will be rough to very rough over the areas of north Andaman Sea, East central and adjoining southeast Bay of Bengal on 9th and 10th October; over central Bay of Bengal on 10th and 11th October and over North Bay of Bengal on 11th October.
