Mumbai Rains: Heavy downpour batters city, IMD issues red alert; rail-road traffic disrupted The National Disaster Response Force (NDRF) has deployed nine rescue teams in Maharashtra, including four in Mumbai, after heavy rains caused flooding in some coastal areas of the state on Thursday. Mumbai, its neighbouring Thane and Palghar and other districts in the Konkan region have been witnessing heavy downpour since the last few days, leading to inundation at several places and disruption of rail and road transport services. Water level of many rivers has risen and crossed the danger mark at some places. An official statement issued by the NDRF said four of its teams have been deployed in Mumbai, and one each in Thane and Palghar districts.
