The Colorado floods have now killed eight people, and at least 648 more are still unaccounted for, NBC News reports. The latest death was an 83-year-old man who was swept three miles downstream when the ground collapsed underneath him in the town of Idaho Springs yesterday afternoon, the Denver Post reports. One pocket of good news: Yesterday's improved weather allowed for more rescues, with helicopters evacuating at least 250 people from areas in Larimer County that had been cut off by the flood, the Post reports. And the National Weather Service is forecasting no more rain this week, the Wall Street Journal reports. "The worst is over," says an National Weather Service employee.
