Weather in Mumbai IMD: The spell of rain in Mumbai is likely to continue till Monday, July 27, when the India Meteorological Department (IMD) issues a yellow alert (heavy rain at isolated places) in Mumbai and Thane districts, along with an orange alert (heavy to very heavy rain at isolated places) in Raigad and Ratnagiri districts. However, the intensity of rainfall is forecast to decrease thereafter amidst the Met Office, indicating that only “moderate rainfall” is likely. In Pune, the IMD has predicted thunderstorms in the city, accompanied by moderate rains.
On Sunday morning, the region woke up to cloudy skies as intermittent rain continued throughout the day. IMD records showed that between Saturday and Sunday morning, the Colaba station received 20 mm of rain while the Santacruz observatory recorded 7.2 mm of rain. During the same period, the neighboring Thane observatory recorded 23 mm of rain. In Navi Mumbai, 37 mm was recorded in Belapur, 36 mm in Koparkhairne, 31.4 mm in Nerul, 24 mm in Vashi, 20 mm in Airoli and 15.40 mm in Digha.
However, by Sunday night, rainfall had reduced considerably, with the Santacruz station recording just 1mm of rain and the coastal station recording NIL rainfall. In its forecast bulletin, the IMD has stated that heavy rain is likely to fall in isolated areas of Mumbai and Thane districts on Monday. Meanwhile, Navi Mumbai in Raigad district may experience heavy to very heavy rainfall, forcing the weather office to issue an orange alert in the district.
Meteorologists have attributed the current spell of rain to a shear zone comprising a low pressure system over the western coast of India that is causing an incursion of moisture and increased rainfall in the Konkan belt and Gujarat.
However, IMD scientists maintained that rainfall activity is about to gradually recede after Tuesday. Starting Tuesday, the weather office has forecast moderate rainfall in Mumbai, Thane and Palghar, even as Raigad district may remain under an extended yellow alert till the end of July.
Boosted by heavy rains in the first week of July as well as the current resurgence of the monsoon, the Santacruz observatory in Mumbai has already received 1,884 mm of rain this season between June and July 26. This represents 80 percent of the city’s actual average rainfall of 2,319 mm. Due to incessant rains, the total stocks in the seven lakes that supply Mumbai’s drinking water supply have also shot up to 12.47 million liters or 86 per cent of the total capacity.
