Officials on Thursday, May 10, were expecting the Clark Fork River to crest at 13.5 feet overnight in Missoula, Montana. The river was forecast to stay at that level through the weekend, a news report said.Evacuation orders were issued earlier in the week, and residents near the flooded areas were told to be prepared to evacuate as the river continued to rise. The river levels around Missoula have not reached their current height since the 1970s. Credit: Dan Walsh via Storyful
