Flood Watch update for western counties (11:30-a.m. 3/13)

Weather

March 13th, 2019 by Ric Hanson

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…

* Showers and thunderstorms will be possible today, with 1 to 2.5 inches of rain through Thursday. Due to the unique combination of heavy rain, continued snowmelt, frozen ground,
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.

Warmer weather is melting the snow, bringing ice jams and flooding

News, Weather

March 13th, 2019 by Ric Hanson

(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.

Council Bluffs and Pottawattamie County Prepare for Potential Historic Flooding

News, Weather

March 13th, 2019 by Ric Hanson

As heavy rains move in and snow melt continues, the potential for river flooding begins. Officials in Pottawattamie County are preparing for what the National Weather Service has described as a flood event that has historic potential, primarily along the West Nishnabotna River. Levels at the Missouri River are forecast to reach a potential 29 feet in minor flood stage by 7am Saturday morning, similar to events observed last summer. The Nishnabotna is forecast to crest at just over 26 feet in major flood stage by 1am Thursday, topping the 23.5 foot record set in July of 1993.

Pott. County EMA

Doug Reed, Pott. County Director of Emergency Management, says “There are many variables in this scenario that will impact the river levels. With existing snow pack, frozen ground, and varying ranges of potential rainfall this event could go either way – however, we need to be prepared for the worst-case potential.” In doing so, a Declaration of Disaster Emergency has been authorized for the communities of Avoca, Hancock, Oakland, Carson, Macedonia, Council Bluffs, and unincorporated areas of Pottawattamie County as a preemptive measure should any of the jurisdictions require assistance from mutual aid partners or state agencies based on actual observed conditions.

Currently, county and city agencies are preparing to secure storm sewer systems, roads, and other infrastructure that may be impacted. Urban streets are likely to experience flooding during the heavy rain event and some rural highways and roads near and around the Nishnabotna River could be closed due to floodwaters. Pottawattamie County Conservation is working to relocate the Botna Bend Park buffalo herd to a safer location and moving the elk herd to a higher elevation within the park. Emergency Management has been coordinating additional resource support with Iowa Homeland Security and Emergency Management should they be needed and coordinating preparedness efforts with partners such as MidAmerican Energy and others.

Residents and people with interests along the rivers are advised to begin monitoring river conditions and prepare accordingly. With frozen ground conditions creating higher runoff than normal, river levels have the potential to rise more rapid than in normal high water and flooding events.
