...Rapid Snowmelt and Rainfall to Bring Increased Flood Risk Later This Week... .The combination of warmer temperatures and forecast rainfall of one to two is anticipated to cause a rapid snow melt across much of central Iowa. The periods of rainfall are expected from today into Thursday, with the highest totals likely to occur Wednesday morning. The runoff from the snowmelt and rain will lead to rises on rivers, streams, and creeks and with these swelling water bodies, any waterway that contains thick ice looks to have the potential for ice jams mid to late this week. Minor to moderate river flooding is possible by Thursday and into the weekend. ...FLOOD WATCH REMAINS IN EFFECT FROM WEDNESDAY MORNING THROUGH THURSDAY EVENING... The Flood Watch continues for

* Portions of all of central Iowa from the Minnesota to Missouri borders.

* From Wednesday morning through Thursday evening

* Rapid snowmelt and expected rainfall is expected lead to significant rises on rivers and streams and the potential for ice jams.

* 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 the upper reaches of Cedar River north of Waterloo. Other locations are possible for ice jam flooding. Minor to moderate river flooding from snowmelt and rainfall is possible in some locations.

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

...Increased Flooding Risk Wednesday into Thursday... .Much warmer temperatures moving into the area will result in rapid snow melt through midweek, with some areas likely seeing much of the current snow on the ground melting by Thursday. In addition, periods of rain are expected beginning this afternoon and continuing into Thursday, with even the potential for a few thunderstorms by Wednesday night. Rainfall amounts up to one inch are currently forecast, with localized higher amounts possible. Run-off from melting snow and rainfall will result in rises for most streams and rivers into late week, with an increased risk for flooding along many of the tributaries of the Mississippi River. At this time, the risk for flooding along the Mississippi River itself appears low this week, but may increase by next week. In urban areas, the effects of snow melt and run-off will be quicker and more easily noticeable where storm drains are clogged by snow and ice. Ponding of water in intersections and low areas may quickly develop. With ice on rivers and streams, there is also a risk for ice jams to develop, which may locally increase the chance for flooding. Those with interests along rivers and streams should remain alert for rising water levels and the threat of flooding the next few days. Now is the time to have a plan in place should flooding develop. ...FLOOD WATCH REMAINS IN EFFECT FROM WEDNESDAY MORNING THROUGH THURSDAY EVENING... The Flood Watch continues for

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

* From Wednesday morning through Thursday evening.

* Warmer temperatures into midweek will create rapid snow melt, with periods of rain also expected. Run-off from melting snow and rainfall will bring rising water levels for many rivers and streams, with an increased risk of flooding. Additionally, break up of ice on rivers may lead to ice jam formation, which could heighten the risk for flooding in localized areas.

* 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.

...RAIN AND SNOW MELT COULD LEAD TO STREET FLOODING AND PONDING OF WATER IN LOW LYING AREAS WEDNESDAY AND THURSDAY... .Temperatures will warm into the 40s Wednesday and Thursday, with around an inch to an inch and a half of rain expected Wednesday into Thursday. The heaviest rain will fall Wednesday afternoon into Wednesday evening. This could lead to street flooding and standing water across low lying areas. Significant rises on the main stem rivers are not expected Wednesday or Thursday. 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 FROM WEDNESDAY MORNING THROUGH THURSDAY EVENING... The Flood Watch continues for

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

* From Wednesday morning 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.
