18 people are unaccounted for after a massive mudslide in Washington state killed at least three people and forced evacuations because of fears of flooding.
Snohomish County Fire District 21 Chief Travis Hots said at a news briefing Sunday that they suspect there are people out there, but the situation is too dangerous for rescuers.
He said the slide is "basically like quicksand." Searchers had to turn back late Saturday after attempting a rescue in an area where signs of life were heard.
Authorities are using helicopters, and plan to drop rescuers into areas if they find signs of life
Hots says he's "in awe" at the scope of the devastation, and that it reminded him of eruption of Mount St. Helens.
"It's basically a square mile area, about six thousand feet by six thousand feet. It's huge, several neighbourhoods."
