Mandatory evacuation orders were issued for low-lying areas of Pagosa Springs and Archuleta County, Colorado, due to rising water levels in the San Juan River.
Heavy rainfall prompted fears of near-historic flooding expected to reach 16.9 feet, closely approaching the 1911 record level of 17.8 feet.
Authorities warned that emergency responders may be unable to reach residents and visitors in evacuation zones once floodwaters rise.
