Heavy rain combined with melting snow can be a destructive combination.
In mid-June 2022, storms dumped up to 5 inches of rain over three days in the mountains in and around Yellowstone National Park, rapidly melting snowpack. As the rain and meltwater poured into creeks and then rivers, it became a flood that damaged roads, cabins, and utilities and forced more than 10,000 people to evacuate.
The Yellowstone River shattered its previous record and reached its highest water levels recorded since monitoring began almost 100 years ago.
