All this rain has caused the National Weather Service to post a flood watch through Thursday. They are looking for sharp rises in river levels, specifically for the North Fork and Middle Fork. At this point, the river level forecast data for Flathead County shows expected heights around flood level for the North Fork at the Canadian border during Wednesday-Thursday. (However, the actual river level readings are running well below the forecast.)
Here’s the official flood watch language:
Statement as of 9:45 AM MDT on June 06, 2012

The Flood Watch continues for
* a portion of northwest Montana… including the following counties… Flathead and lake.
