: "It’s a matter of life or death."
Yellowstone has been battered by heavy rain in recent days.
Around two-and-a-half inches of rain were reported on Saturday, Sunday, and Monday.
Meteorologists at the National Weather Service revealed that the Beartooth Mountains saw as much as ten inches of rain.
But, weather experts said that snowmelt has also contributed to the flooding.
NWS meteorologist Cory Mottice said: "It’s a lot of rain, but the flooding wouldn’t have been anything like this if we didn’t have so much snow.
"This is flooding that we’ve just never seen in our lifetimes before.”
Those who are planning to visit Yellowstone in the coming weeks are being urged to check road conditions.
The Sun has reached out to Yellowstone National Park officials regarding this incident.
