AlQa'dah 7, 1434, Sep 13, 2013, SPA -- Thousands more people in Colorado were ordered to evacuate as water rose to dangerous levels amid a storm system that has been dropping rain for a week. According to AP, rescuers struggled to reach dozens of people cut off by flooding in mountain communities. At least three people were killed. Boulder County spokesman James Burrus said 17 people were unaccounted for Friday. "Unaccounted for doesn't mean missing. It means we haven't heard back from them," he said. Two backpackers were said to be missing as well after they were hiking in the mountains and the changing weather caught them by surprise, a family member said.
