(CNN) -- Portugal declared three days of national mourning Monday amid fears the death toll from devastating floods and mudslides on the island of Madeira could rise above 42. Search teams have been working to find more victims after floodwaters caused by heavy rains swamped the capital Funchal, unleashing a torrent of mud that swept away homes, roads and trees. At least 120 people were injured. Rescuers were trying to drain a two-story undergound car park at a shopping center where many people are thought to have become trapped. Rescuers feared were that when rains started on Saturday many people may have rushed to retrieve their cars, but ended up trapped in the car park, CNN's Portuguese affiliate, RTP state TV, reported.
