Heavy rainfall of more than 200mm is expected over parts of central India and the west coast in the next 3-4 days, potentially resulting in flash floods at several locations, the India Meteorological Department (IMD) warned on Sunday.
On Saturday evening, a low-pressure area formed as a result of a cyclonic circulation over the northwest Bay of Bengal and its surroundings off the coasts of Odisha and West Bengal, according to a weather forecaster. This is expected to become a depression and move west-northwest across Odisha and Chhattisgarh.
The monsoon trough, an elongated area of low pressure, is also active and south of its normal position, and will remain so for the next 4-5 days, according to the weather service.
"On Sunday, some parts of Odisha and the Konkan region began to receive very heavy and extremely heavy rain." Rain will increase over central India over the next 3-4 days as a result of the depression," said M Mohapatra, director general of IMD.
"Inundation of low-lying areas is possible when there is extremely heavy rainfall." "We issued a flash flood warning for Odisha," said Mohapatra. "The Central Water Commission will issue warnings for riverine floods." The local population should brace themselves for heavy rain."
Rainfall will be reduced over Uttar Pradesh, Bihar, and Gangetic West Bengal as the depression moves over Maharashtra, Madhya Pradesh, and Gujarat, he predicted. As of Sunday, there was a 6% excess over the country, with a 37% excess over the south peninsula, a 9% excess over central India, a 1% excess over northwest India, and a 15% deficiency over east and northeast India.
Rainfall is deficient in 46 percent of Gangetic West Bengal, 48 percent in Jharkhand, 34 percent in Bihar, 44 percent in eastern Uttar Pradesh, and 38 percent in western Uttar Pradesh. According to the weather bureau's monthly climate summary, East and Northeast India had the lowest rainfall and the highest maximum, mean, and minimum temperatures in July in 122 years.
"This depression, like the lows that formed in July, will form south of its normal position." It is not forming over the head of the bay. That is one of the reasons why it is unlikely to bring rain to the rain-scarce region of the Indo-Gangetic plains," said Ananda Das, the weather office's cyclone tracker.
The agency has issued a red alert for Monday in Telangana and Maharashtra, and an orange alert for Tuesday and Wednesday in central and western India, including Madhya Pradesh, Chhattisgarh, Gujarat, and Maharashtra. Authorities must take action to prevent rain-related disasters in these areas.
Widespread rain, thunderstorms, and lightning are expected over Jharkhand on August 9 and 10; Odisha on August 10, Andaman and Nicobar Islands on August 7 and 8, and Assam, Meghalaya, Nagaland, Manipur, Mizoram, and Tripura on August 7-9. Isolated heavy rain is expected over Odisha on August 8 and 10, as well as over Gangetic West Bengal on August 9 and 10.
