Flooding continues to be a concern on rivers and streams across western and central Montana. In Missoula, evacuation orders are still in place for 65 homes, with warnings posted for an additional 2,200 more. But there’s at least a glimmer of good news for the Clark Fork River above Missoula.

When the weather gets dramatic, the big-picture descriptions come out: a 50-year storm, a hundred-year flood, a thousand-year floodplain. But it can get confusing when the numbers don't really mean what they sound like to the non-statisticians among us who hear them.

For example: a hundred-year flood doesn't mean that it's breaking a 100-year-old record.

The Clark Fork River above Missoula today receded by over two feet from Friday night’s high of 13.82 feet; its highest crest since 1908. But that doesn't mean the worst of the flooding is behind us.

"Even though the rivers have gone down now, lets not be complacent cause they’re going to be headed right back up Thursday through Saturday,” says National Weather Service Meteorologist Bob Nester.

Rivers and streams across western and parts of central Montana are steadily rising as record mountain snowpack continues to melt.

It seems the passage of Montana’s seasons isn't marked so much anymore by gradually changing weather as it is natural disasters.

Western Montana’s flood waters receded a little bit Thursday, but it’s only a temporary reprieve. Warmer temperatures are on the horizon, and there’s more snowpack left in the mountains. Lots more.

The weekend’s cold front dropped a lot of rain over western Montana and sent the Clark Fork into a minor flood stage by mid-morning Sunday.

According to Missoula National Weather Service meteorologist Bob Nester says the river was expected to reach moderate flood stage by Tuesday evening.
