Flood in Flathead County, Montana

Glacier National Park Dispatch reported several flooding impacts west of the Continental Divide. Sprague Creek reached its banks, and water from Logan Creek began coming onto the road. Claudes Creek, located west of Claudes Corner, flooded the roadway, and water levels were close to overtopping the road at Claudes Corner itself. The Going to the Sun Road was closed at Avalanche Creek. Additionally, multiple temporary closures were reported across Glacier National Park due to flooding and debris on the roadways, particularly near the Loop and along McDonald Creek.

Wraparound precipitation from a closed low pressure system located east of the Continental Divide sent abundant moisture into the Northern Rockies. Saturated ground conditions from previous rainfall combined with an additional two to four inches of precipitation, resulting in flooding across parts of northwest Montana.
