The death toll has risen even higher after a devastating landslide in Washington state.
Officials have not announced new numbers.
At last count, at least 16 people are confirmed dead and another 176 remain unaccounted for after a massive collapse ravaged two towns north of Seattle on Saturday.
President Barack Obama urged prayers for the victims at a press conference in the Netherlands.
"I would just ask all Americans to send their thoughts and prayers to Washington state, and the community of Oso and the families and friends of those who continue to be missing," Obama said. "We hope for the best, but we recognize this is a tough situation."
