Key Points
- Near normal spring flood risk for the Mississippi River (decreased from Outlook #2).
- Near to slightly below normal spring flood risk for local tributary rivers (little change from Outlook #2).
- Future precipitation events and rate of snowmelt in the upper Mississippi basin will be the main factors in determining the occurrence and severity of any flooding this spring.
Details
The spring flood risk is near normal for the Mississippi River, and near to slightly below normal for local tributary rivers across the NWS Quad Cities Hydrologic Service Area. The flood risk has decreased slightly on the Mississippi River, compared to the second outlook, with little or no change noted in flood probabilities for area tributary rivers.
While the overall risk of spring flooding is not high, this does not mean that flooding will not occur. This will be determined by key factors including future precipitation events, and snowmelt in the Upper Mississippi basin.
Some factors contributing to the near normal to decreased risk include: 1) Near to below normal soil moisture and winter precipitation. 2) Lack of widespread or deep snowpack, with the exception of the upper reaches of the Mississippi River basin. 3) Near normal river levels
