Sixty homes in Missoula, Montana were mandatorily evacuated due to flooding on Tuesday.

Heavy precipitation during early May and recent snowmelt from nearby mountains mixed to send rivers and streams in several parts of Western Montana flowing out of their banks. The Clark Fork River is a main artery running through the middle of Missoula and is the site of the most severe flooding. 1,300 homes along the river were encouraged to prepare for a possible evacuation.

Ken Parks is the Missoula County Disaster and Emergency Services deputy coordinator. He said to the Associated Press, “If you live anywhere near a stream or waterway in western Montana you need to be prepared to leave your home. This is going to come earlier than we expected. We’re trying to get out ahead of this thing and get the message out that this could be a very dangerous situation.”

From 1955 to 2016, snowpack on mountains in the Western United States declined by an average of 23 percent, according to the U.S. Environmental Protection Agency. However, Western Montana has really only seen the beginning of this spring’s snowmelt, according to authorities from the National Weather Service. Some parts of the local mountain range are expected produce 55 additional inches of snowmelt through the spring and summer. The Clark Fork River is expected to reach higher levels than it has since 1981 this year.
