MUMBAI — Persistent monsoon rains pounded India's western Maharashtra state on Monday, killing at least 11 people, crippling road, rail and air transport, and triggering landslides, flooding and building collapses as authorities warned residents to stay indoors and avoid all non-essential travel.Six people including five children were killed when a building collapsed in Mumbai, officials said, as heavy rains hit India’s financial capital, flooding roads and leading to school closures.Three members of a family were killed when a pre-dawn landslide buried their home in Patan village in Pune’s Maval tehsil, while eight others died in separate rain-related incidents in Mumbai.Two more people died in separate tree-fall incidents as powerful winds lashed the city, media reports said.A dilapidated residential building collapsed Sunday in the megacity’s east, trapping residents under the debris, Mumbai Mayor Ritu Tawde said in a statement.The deaths came as heavy rainfall paralyzed the city, with the India Meteorological Department recording more than 200 millimeters (7.8 inches) of rain within 24 hours.The weather office has issued a red alert warning for Mumbai on Monday, forecasting continued heavy rain and gusty winds.With roads inundated, Mumbai authorities declared Monday a holiday for all schools and colleges.Mayor Tawde called on people to stay indoors if possible, warning of falling trees and branches due to strong winds.Heavy rain also crippled one of India’s busiest transport corridors after landslides and flooding forced authorities to suspend traffic on both the Mumbai-Pune Expressway and the old Mumbai-Pune Highway.Chief Minister Devendra Fadnavis said nearly 100 tons of debris crashed onto the expressway. One lane towards Mumbai was later reopened after about 70 per cent of the debris was cleared, but police urged commuters to postpone non-essential travel between the two cities.The downpours follow weeks of sweltering heat, with authorities imposing restrictions on water use last month and cutting supplies to swimming pools and construction sites.The city of over 20 million people is grappling with concerns over pressure on water resources from expanding data-center infrastructure, whose large cooling requirements could exacerbate supply strains.
