Rainfall activity in Mumbai and its adjoining areas is likely to increase from Sunday, the India Meteorological Department (IMD) has said.
A district forecast issued by the IMD said heavy rain at isolated places was very likely in Mumbai on Sunday, while an orange alert with a forecast of heavy to very heavy rain at few places has also been issued for the city, Thane and Palghar from August 3. Konkan region is also set to receive heavy rain from Saturday.
“There could be an enhancement of rain over the west coast from today (Friday) onwards for south Konkan. North Konkan, including Mumbai, Thane and Navi Mumbai, is likely to get heavy rain from Sunday. The trend is likely to continue with further increase in rainfall activity,” KS Hosalikar, Deputy Director General (western region), IMD, said.
A bulletin issued by IMD stated: “Due to convergence of strong lower-level winds over the west coast, widespread rainfall with isolated heavy to very heavy falls are most likely along the west coast during the next five days. Extremely heavy rainfall is also likely over Konkan and Goa on August 4.”
