Flood Outlook issued March 13, 2025 - Final Outlook

Key Points

  • The risk of spring flooding is below average across southern Wisconsin.
  • The spring flood risk is based on the following factors: Little snowpack, average streamflow values and average to below average soil moisture. In some areas the ground is still frozen which can result in increased runoff and flooding potential.
  • This flood risk pertains to the underlying risk for the mid March to the mid June time period as a whole. The risk may be higher with individual weather events. Flooding is still possible with heavy rain.
  • River flooding in southern Wisconsin typically occurs in March and April when there is a rapid snowmelt and/or heavy rain, but it can happen any time of the year.

What Has Changed

  • Frost depth has decreased and the top layer is thawing and the ground is completely thawed in some areas, reducing the flood risk.
  • River ice has melted, however many lakes remain frozen.
