is resulting in rises in creeks and streams across the area. Local
law enforcement and spotters have reported several county roads
with water over them. In addition, another round of moderate
rainfall will impact portions of western Iowa this afternoon with
an additional 0.25 to 0.75 inches of rainfall possible. This
rainfall will lead to additional flooding impacts along creeks and
streams and low lying areas. Ice jams are also possible.
* Some locations that may experience flooding include…
Creston, Atlantic, Greenfield, Mount Ayr, Corning, Bedford, Stuart,
Lenox, Griswold, Sun Valley Lake, Green Valley Lake, Lake Icaria,
Anita, Afton, Adair, Fontanelle, Lewis, New Market, Orient and
Clearfield.
PRECAUTIONARY/PREPAREDNESS ACTIONS…
Turn around, don`t drown when encountering flooded roads. Most flood
deaths occur in vehicles.
Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, country roads, farmland, and other low lying
spots.
MODERATE TO MAJOR, AND POSSIBLY HISTORIC FLOODING EXPECTED TO DEVELOP…
.Heavy rain, combined with warmer temperatures and melting snow, frozen ground, and thick ice cover in the rivers will lead to widespread flooding on many rivers and streams. Minor flooding of some roads have already occurred, as well as urban flooding in areas where drains were blocked with snow and ice. Many rivers will experience moderate to major flooding, and in some cases, record flooding is forecast. Ice jams could also develop with little notice which would enhance the flood threat. Road closures are possible in flooded areas.
Monona-Harrison-Shelby-Pottawattamie-Mills-Montgomery-Fremont-
Page Counties in Iowa……FLOOD WATCH REMAINS IN EFFECT THROUGH THURSDAY EVENING…

and thick ice cover on area rivers, widespread flooding is expected. Many rivers will experience moderate to major flooding, and in some instances, record flooding is possible.
* ADDITIONAL DETAILS…Significant and rapid river level increases are possible due to excessive runoff. Ice jams could also develop with little notice which would further enhance the flood
threat. Many rural roads could be inundated, and urban flooding may occur in poor drainage areas.
PRECAUTIONARY/PREPAREDNESS ACTIONS…
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 quick action should flooding develop.

(Radio Iowa) — It’s said April showers bring May flowers, but after Iowa’s snowiest February on record, March showers bring widespread flooding. Meteorologist Brooke Hagenhoff, at the National Weather Service, says there are flood watches and warnings all across the Iowa map and some roads are already barricaded off due to the high water. “We’ve got several areas that are forecast to go into either minor or moderate flooding,” Hagenhoff says. “Luckily, we’re not seeing that quite yet, other than in a few locations, but definitely with the continued snowmelt that we’re seeing and extra rainfall today, it’s only going to enhance that.”
Some waterways in southwest Iowa and across much of eastern Iowa have already seen water levels double in the past 24 hours. “The areas we’re really most concerned about are where we’re looking at ice jam potential,” Hagenhoff says. “Those can be especially hazardous just because they can happen fairly quickly with rapid rises and you don’t get a lot of warning.” Indianola and Ottumwa had flash flooding due to ice jams on Tuesday. Other areas of particular concern for ice jams include Marshalltown, Fort Dodge, Van Meter and north of Waterloo. The forecast calls for much warmer weather today (Wednesday), with high temperatures in the upper 40s in northern Iowa to near 60 in southern Iowa. Hagenhoff says there’s still deep snowpack in parts of the state. “We’re pushing ten to 15 inches across portions of northern Iowa,” Hagenhoff says. “Those areas will be a little cooler today but certainly, we’re expecting to see quite a bit of snowmelt all the way through central Iowa. Southern Iowa has seen a lot of melting already and in many cases, their snowpack has completely disappeared.”
The National Weather Service is again posting warnings to motorists approaching flooded waterways, telling them to “Turn around, don’t drown.” “The biggest thing is just to be aware,” she says. “If you can’t see the road through the water, it’s probably a good idea to just turn around and find a different route. You never know how deep it is or what the road conditions are like under that water.” Even in areas where the snow is already long gone, Hagenhoff says there’s concern about flooding as waterways are swelling with runoff from snowmelt upriver.
