Spring Flood Outlook

Some erosion of the current deep snowpack over Northeast Wisconsin is in store  for the beginning of next week with temperatures climbing into the lower to middle 40s on Monday. This may lead to runoff and the primary concern  for flooding would be for clogged storm drainage systems. After that, temperatures are expected to cool once again to below normal for the rest of next week, which will allow for a more gradual melting of the snowpack.

This flood outlook is for the NWS Green Bay service area. It covers the time period from March through early June 2014.

This includes the following rivers: Yellow River, Menominee River, Wolf River, Little Wolf River, Waupaca River, and Oconto River.
The risk of minor flooding remains slightly above normal due to the persistence of a widespread deep snowpack. The delayed runoff of the snow pack may combine with spring rain runoff to potentially increase the risk of flooding. Due to the forecast of below normal temperatures through March, ice break up for the area rivers will likely be delayed deeper into March and more than likely into April  for northern rivers and streams.
