Wider weather episode

After a hot start to September, a cold weather system brought widespread low elevation rain and snow accumulations above 6000 feet across the Northern Rockies impacting back-country hunters, wildfire crews and travel across mountain passes. The large degree of change coupled with the somewhat unseasonable timing of this event produced greater than normal impacts.
