The death toll from the mudslide in Washington state rose to 30 people on Thursday morning, according to local officials. In addition, Snohomish County released a list of 15 people believed to be missing due to the landslide. This came a day after President Obama signed a disaster declaration, which makes federal funding available to people in the area.

It has been nearly two weeks since the landslide, which decimated a stretch of land in the state, destroyed houses and left a monstrous field of debris in its wake.
