One woman who made her way out of the tunnel said she was with five other people in a van, but added: "I have no idea about what happened to the others. I don't know how many vehicles were ahead and behind ours."
With just two days to go until Christmas, rail services have been suspended and many roads are flooded. In Devon, one woman was rescued by a police helicopter after she was swept away by floodwater and left clinging to a tree.
Eyewitnesses said the victim was standing on a platform at the Queens subway station when a woman rose from a bench and shoved him onto the tracks as a train arrived at the station.
