HELENA, Mont. — A torrent of rain combined with a rapidly melting snowpack caused a deluge of flooding that forced the evacuation of some parts of Yellowstone National Park, cutting off electricity and forcing park officials to close all entrances indefinitely, just as the summer tourist season was ramping up.
While numerous homes and other structures were destroyed, there were no immediate reports of injuries. Yellowstone officials said they were assessing damage from the storms, which washed away bridges, caused mudslides and left small cities isolated, forcing evacuations by boat and helicopter.
