Those still missing are:
- John "Jack" Cantin, 17

The first rain in months caused mudslides when it hit ground that had been scorched by widespread wildfires in December.
After a wildfire, burned vegetation and charred soil create a water repellent layer which blocks water absorption.
Together with the loss of vegetation, this leads to an increased risk of mudslides and floods.
Five hundred extra emergency rescuers arrived over the weekend, joining more than 2,100 personnel from local and national agencies, including the US Coast Guard, the US Navy and the American Red Cross.

A spokesperson for the response team said the relief effort of 3,000 personnel was still in "rescue mode".
"We still hope to find someone alive, although the chances of that are becoming slim," Justin Cooper told Reuters news agency.

It is likely that they will be away from their homes for several weeks as the rescue and recovery efforts take place.
