NWS DesMoines (Central Iowa)
...River flooding and Significant Ponding Water Likely This Week Due to Snowmelt and Expected Rainfall... .The combination of warmer temperatures and forecast total rainfall amounts of one to near two inches is going to lead to a rapid snow melt across much of central Iowa. Significant ponding of water in low lying, poor drainage is likely, potentially impacting roads and travel. Periods of rainfall are likely today into Thursday, with the highest totals occurring today into this evening. The runoff from the snowmelt and rain will lead to significant rises on area streams. Ice jam flooding may occur, creating rapid rises upstream of the jams. Minor to moderate river flooding is possible by Thursday and into the weekend. ...FLOOD WATCH REMAINS IN EFFECT THROUGH THURSDAY EVENING... The Flood Watch continues for

* Portions of central Iowa, north central Iowa, northeast Iowa, northwest Iowa, south central Iowa, southeast Iowa, southwest Iowa, and west central Iowa, including the following areas, in central Iowa, Boone, Dallas, Grundy, Hamilton, Hardin, Jasper, Marshall, Polk, Poweshiek, Story, Tama, and Webster. In north central Iowa, Butler, Cerro Gordo, Franklin, Hancock, Humboldt, Kossuth, Winnebago, Worth, and Wright. In northeast Iowa, Black Hawk and Bremer. In northwest Iowa, Emmet, Palo Alto, and Pocahontas. In south central Iowa, Appanoose, Clarke, Decatur, Lucas, Madison, Mahaska, Marion, Monroe, Ringgold, Union, Warren, and Wayne. In southeast Iowa, Davis and Wapello. In southwest Iowa, Adair, Adams, Cass, and Taylor. In west central Iowa, Audubon, Calhoun, Carroll, Crawford, Greene, Guthrie, and Sac.

* Through Thursday evening

* Rapid snowmelt and rainfall is expected to 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.

NWS LaCrosse (Southwestern Wisconsin, Southeastern Minnesota, and Northeast Iowa)
...Increasing Flood Risk From Rain, Snow Melt... .Periods of rain will continue through Thursday with additional rainfall amounts of around half an inch possible. Runoff from rainfall and snow melt will result in rises on many rivers and streams over the next few days, along with an increased risk for ice jams. Flooding is anticipated on many waterways through late week, and potentially through portions of next week as well. In addition, urban and street flooding could occur from clogged storm sewers with additional hazards from debris on roads. Currently, major flooding is expected on the Turkey and Volga Rivers with moderate flooding on the Upper Iowa. In addition, minor flooding is likely along portions of the Kickapoo and Root Rivers, with other waterways also likely to experience flooding. At this time, the risk for flooding along the Mississippi River is low through the weekend, but will likely increase into next week. Those with interests along rivers and streams should remain alert for rising water levels and the threat for flooding. Now is the time to have a plan in place should flooding develop. ...FLOOD WATCH REMAINS IN EFFECT THROUGH FRIDAY MORNING... The Flood Watch continues for

* All of northeast Iowa and southeast Minnesota, and much of western, central, and southwestern Wisconsin.

* Through Friday morning

* Runoff from periodic rain along with snow melt will result in rises on many rivers and streams, along with an increased threat for ice jams. Flooding is anticipated on many of the waterways. In addition, urban and street flooding could occur from clogged storm sewers with additional hazards from debris on roads.

* Those residing near waterways should closely monitor conditions this week, and be prepared to take action if flooding develops.

A Flood Watch means there is a potential for flooding based on current forecasts. Please monitor conditions and forecasts, and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.

NWS Minneapolis (Southern Minnesota)
...RAIN AND SNOW MELT COULD LEAD TO STREET FLOODING AND PONDING OF WATER IN LOW LYING AREAS THROUGH THURSDAY... .Temperatures will remain mild through Thursday morning, with around an inch, up to an inch and a half of rain expected later today, and into tonight, especially in west central and central Minnesota. The heaviest rain will fall this afternoon and evening. This could lead to street flooding and standing water across low lying areas. Significant rises on the main stem rivers are not expected this week. Many of the the drainage systems are full of ice and snow, so any melting or runoff from the rain could lead to ponding of water in low lying areas. Temperatures will fall below freezing Friday, so any standing water will become ice. ...FLOOD WATCH REMAINS IN EFFECT THROUGH THURSDAY EVENING... The Flood Watch continues for

* A portion of south central Minnesota, including the following areas, Faribault, Freeborn, Martin, Steele, and Waseca.

* Through Thursday evening

* Snow melt and rainfall may result in flooding in poor drainage areas.

A Flood Watch means there is a potential for flooding based on current forecasts. Clear the snow and ice away from your storm drains before Wednesday. 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.
