...River flooding and Significant Ponding Water Continues To Be

Likely Into Thursday Due to Continued Snowmelt and Additional


.Many reports of ice jams and poor drainage from frozen culverts

and lingering snow has led to flooding in low-lying areas across

many areas already. More flooding is expected due to additional

snowmelt and rainfall today into Thursday. Mainly lighter rain is

expected into Thursday, however with temperatures remaining above

freezing the potential for additional flooding will still be

possible. The runoff from the snowmelt and rain will lead to

significant rises on area streams. Additional ice jam flooding

may occur, creating rapid rises upstream of the jams. Minor to

moderate river flooding is possible by Thursday and into the

* Through Thursday evening

* Rapid snowmelt and additional rainfall could lead to

significant ponding of water in low lying, poor drainage areas.

The added water and the potential for ice jams may lead to

significant rises on rivers and streams.

* Favored ice jam locations include the Des Moines River around

Fort Dodge, the Raccoon River around Van Meter through Des

Moines to the confluence of the Des Moines River, the Iowa

River around Marshalltown and Tama, and the upper reaches of

Cedar River north of Waterloo. Minor to moderate river

flooding may occur.


A Flood Watch means there is a potential for flooding based on

current forecasts.

If you live in ice jam flood prone areas, be aware of potential

significant rises on area streams through Thursday.

You should monitor later forecasts and be alert for possible

Flood Warnings. Those living in areas prone to flooding should be

prepared to take action should flooding develop.
