Mumbai and its neighbouring districts remained drenched for the third consecutive day as heavy downpour continued to batter the Mumbai Metropolitan region throughout on Wednesday.A day after over hundred millimetres of rainfall battered the city, Mumbai’s suburban pockets continued to receive over 100 mm rainfall in a span of eight hours on Wednesday – leaving streets inundated, bringing traffic to a crawl, and triggering collapses of homes and trees.The region’s wet spell is here for a prolonged stay with the India Meteorological Department (IMD) sounding a red warning of heavy to extremely heavy rainfall in Palghar on Thursday, while Thane and Raigad districts have been placed under a red alert between July 3 and 4. In light of the red warning, the district collector in Palghar announced a public holiday across all schools of the district on Thursday.Like its neighbouring districts, Mumbai is also poised for torrential rainfall until the end of this week, with the weather bureau issuing an orange alert across the city till July 5 owing to the possibility of heavy downpour.According to meteorologists, rain activity is poised to gather pace and remain intense till July 7 owing to the influence of multiple active monsoon systems. Currently, an upper air cyclonic circulation lies over Bay of Bengal and its neighbourhood, which is expected to influence the formation of a low-pressure area by July 3.A low pressure area is one where pressures are lower than the surrounding region, ushering in moisture and triggering intensive downpour.Additionally, a trough presently runs over the upper air cyclonic circulation while an off-shore trough at mean sea level is likely to prevail in the next one week.Story continues below this adAmid favourable monsoon factors, data from the IMD’s observatory and civic automatic weather stations showed that between Tuesday and Wednesday morning, Mumbai’s Santacruz station received 96.3 mm rain while Colaba station recorded 69.6 mm rain.
