New Delhi: With the onset of monsoon in several parts of India, the India Meteorological Department (IMD) has now predicted formation of low-pressure area over the North Bay of Bengal and neighbourhood on Friday.

According to the IMD prediction, the pressure over the region will become more pronounced and move west northwestwards across north Odisha, Jharkhand and north Chhattisgarh during the subsequent three days. "A cyclonic circulation lies over East-central and adjoining Northeast Bay of Bengal at middle tropospheric levels, under its influence, a Low-Pressure Area is likely to form over North Bay of Bengal and neighbourhood around 11th June, 2021," the weather department said.

Under its influence, widespread rainfall activity with heavy to very heavy falls is very likely to occur over most parts of east India and adjoining central India from today. Extremely heavy rain (≥ 20 cm) is also very likely over Odisha on June 11 and 12; over Chhattisgarh from June 11 to 13; over east Madhya Pradesh on June 13; and over Vidarbha on June 12 and 13.

With the passing of the northern limit of monsoon (NLM) through, rains are expected in Surat, Nandurbar, Betul, Mandla, Bilaspur, Bolangir, Puri and Bagdogra. Conditions are favourable for its further advancement into some more parts of Gujarat, Madhya Pradesh, remaining parts Chhattisgarh and Odisha, the entire West Bengal and Jharkhand, some parts of Bihar and east Uttar Pradesh, and remaining parts of north Bay of Bengal during the next 24 hours.

Due to the strengthening of westerly winds along the west coast in association with low-pressure area, widespread rainfall activity with heavy to very heavy falls likely to continue over coastal districts of Maharashtra from 9th to 15th June and likely over coastal Karnataka from 12th to 15th June.

The met department also predicted isolated heavy rainfall over Kerala from 11th to 15th June. Extremely heavy falls also very likely over Konkan from 12th to 15th June.

Due to west-northwestwards of low-pressure area and its remnant, fairly widespread to widespread rainfall activity with isolated heavy falls is very likely over northwest India (excluding Rajasthan) from 12th to 14th June.
