I figured it was a good time to start this thread as the North Central River Forecast Center just came out with their first spring flood forecast.

Initial prognosis is that this year has a high potential of flooding along the Upper Mississippi and surrounding rivers. Factors for this forecast include how wet the soils still are from last year, the fact that a lot of rivers in the midwest are having really high flows for this time of year, and the heavy and wet snowpack up north. Basically if any area gets a large amount of rain this year they are going to possibly have some significant flooding. Oh yeah and not too mention the extremely high levels of the Great Lakes which will undoubtedly go up through the spring. In fact, Lake Michigan-Huron is only a few feet away from flood stage. Overall this year looks to be a very interesting year in the Midwest for flooding.
