June 2008 ArchivesNow that the Mississippi River is cresting (or nearly cresting) in our area, our focus in the 4Warn Storm Center is changing. You'll hear less and less now about crest times and heights, and more about the duration of the crest. Unfortunately, in a major river flooding event like this one, water levels don't typically drop quickly after cresting. Many locations up and down the Mississippi River will spend two or thre... *****Yet Another Update, Thursday Evening June 19th********** We Never Stop looking over the latest flood information and there has been a significant change. Because of levee breaches North of St. Louis, the crest forecast along the Mississippi has changed significantly. Along the Mississippi in our viewing area the crest is forecast to be 1 to 2 feet lower than previously thought. This means levels should be below the record crest... ***UPDATED THURSDAY, JUNE 19*** Can that possibly be? Indeed, the latest river level forecasts indicate that this episode of flooding on the Mississippi River may actually approach (if not surpass) those record levels set in the Great Flood of 1993, at least upstream from Grafton (north of St. Louis).

This river flooding issue is a complicated one, mainly because different local rivers will be impacted in dramatically different ways. For example, while m...

The Mississippi at Grafton is forecast to rise to 28.5' which is 10.5' above flood stage. That's right on the borderline of what's classified by the weather service as "Major Flooding". Here's a list of what is impacted in the Grafton area when the... After a weekend of heavy rain in Nebraska, Iowa, Wisconsin and Northern Illinois, much of that rain will run into streams that eventually dump into the Missouri or Mississippi River. Because of this, the Missouri and Mississippi Rivers will be on the rise into this upcoming weekend. In fact, below is the river level graph on the Mississippi River at St. Louis. You can see the sharp rise in the water level forecasted for this weekend. At St... |
