DAVENPORT, Iowa (KWQC) - Earlier in March, the National Weather Service released its third Spring Flood Outlook calling for ‘well above normal’ risk of flooding along the Mississippi River and a ‘near to above normal’ threat of flooding on tributary rivers.

While the overall threat of major flooding (18 feet) on the Mississippi River has decreased, NWS said the risk of minor (15 feet) to moderate (16 feet) flooding remains at 95% or greater.

Other local rivers such as the Rock, Wapsipinicon and Cedar have a near normal risk for spring flooding.

Two key factors are tied to potential flooding: temperatures and how quickly the snow melts to our north near the headwaters of the Mississippi River.

Those areas have seen near record amounts of snowfall and moisture during the winter season. Rapids snowmelt would lead to an increased risk of flooding, while a slower snowmelt would decrease the threat.

Any additional heavy rain events locally could change the overall flood potential given the fact that soil moisture are above normal for the season.
