The weather office has sounded a "red alert" for heavy rain tomorrow in Mumbai, which reported 200 mm of rain today, about nine times more than average. Schools and colleges will be closed on Wednesday. Chief Minister Devendra Fadnavis tweeted to say that people in and around Mumbai are "advised to stay back home unless there is an emergency", but "essential services and critical staff in Government will be on duty tomorrow". Operations at the Mumbai airport, suspended for a while on Tuesday evening because of low visibility, have resumed. But flights are delayed, as are trains.
