After a lull, the monsoon is set to make a resurgence Maharashtra, including in Mumbai and its surrounding areas, starting from September 7. The India Meteorological Department (IMD) has issued a green alert, signifying moderate rainfall, for Mumbai on September 7, 8 and 9 and a yellow alert, indicating rainfall accompanied by thunderstorms and gusty winds, for September 10.

According to the IMD's forecast, beginning on September 7, widespread rainfall is expected in all regions of Maharashtra, including North Konkan, South Konkan, Goa, North Central Maharashtra, Marathwada, East Vidarbha, and West Vidarbha. Interestingly, Mumbai was under a green alert on Wednesday, but in the 24-hour period ending on the morning of September 6, the Santacruz weather station recorded a mere 0.1 mm of rainfall, while the Colaba observatory reported no rainfall.

In light of this anticipated shift in weather patterns, Rajesh Kapadia, author of the private weather blog Vagaries of the Weather, remarked, "The monsoon is turning active, and much-needed rainfall is expected across most parts of the country in the coming days. Rainfall is expected to intensify around September 8 in the Mumbai region, with moderate rain and occasional heavy showers likely over the weekend on September 9 and September 10. There is also a possibility of thunderstorms."

Sushma Nair, a scientist at IMD's Mumbai Regional Meteorological Centre (RMC) in Colaba, said, "Over the next week, the city is likely to experience moderate-intensity rainfall. While the rainfall is not expected to be heavy, it should provide some relief from the dry spell experienced throughout August." The low-pressure system over the Bay of Bengal will move inland starting from September 7, gradually weakening and shifting westward.

Owing to the low pressure in the north Bay of Bengal, westerly winds will strengthen, enhancing the rain activity over Mumbai and adjoining coastal areas during this week. However, the intensity of rains in Mumbai and adjoining areas will not be as strong as the other regions of the state."

Monsoon till Oct 10

Regarding the current water levels in the city's lakes, Kapadia added, "The lakes that supply water to Mumbai currently have water stocks that will last up to nine months. If the city manages to receive 350-400 mm of rainfall during the remaining days of the monsoon season, it should conclude the season with full water storage capacity. Monsoon conditions are expected to persist in Mumbai until October 10."
