Cedar Rapids preps for “major” flood event

News, Weather

September 5th, 2018 by Ric Hanson

(Radio Iowa) — The city of Cedar Rapids is bracing for flooding after days of heavy rains. The Cedar River is forecast to crest at 16-and-a-half feet tomorrow (Thursday), which is six inches above major flood stage. City workers are closing roads, parks and boat ramps. Cedar Rapids Public Works Director Jen Winter says any impacts would likely come from the river flowing into the storm sewer system.
“Unless something fails, we anticipate that there would not be damage,” Winter says. “In some cases, depending on the age of a building, some people do get water in their basements despite the fact that we have kind of plugged off the river from backing up.”

While the forecast is for 16-and-a-half feet, city workers are preparing for at least 18 feet of water, just to be safe. Winter says they’re also plugging manholes and storm drains to prevent backflow. “The majority of the risk is from underground,” she says, “so the majority of the risk is from water coming back into our storm sewer system and backing up.”

City leaders are urging residents to stay away from the river and to let workers finish their preparations. As updated forecasts become available, the city will consider adding more protections. Cedar Rapids’ last major flood came in 2016, when the river crested at 22 feet.

Cedar Rapids taking steps to keep floodwaters at bay

News, Weather

September 5th, 2018 by Ric Hanson

CEDAR RAPIDS, Iowa (AP) — Cedar Rapids is taking steps to protect the city from Cedar River floodwaters. The National Weather Service says the river was nearly 3 feet (1 meter) above flood stage Wednesday morning and is expected to crest at more than 4 feet above flood stage on Sunday morning. City officials say their preparations include placing sand-filled barriers in low-lying areas and closing gates to the city’s storm sewer system, which will protect the NewBo District and most of the downtown. Sandbagging stations have not been opened, but preparations for two have been made.

Gordon to bring flash flood threat to Midwest

News, Weather

September 5th, 2018 by Ric Hanson

Forecasters say remnants of Tropical Storm Gordon could cause flash flooding across parts of seven states — as far north as southern Iowa — in coming days. In its latest update before dawn today (Wednesday), the National Hurricane Center says the storm is expected to leave total rain amounts of 4-8 inches in the Florida panhandle and parts of Alabama, Mississippi, Louisiana, Arkansas, Missouri, Iowa and Illinois.

The Hurricane Center says that isolated amounts of 12 inches will be possible in parts of the region through early Saturday. Though Gordon is expected to weaken to a tropical depression sometime Wednesday morning, forecasters say tornadoes will still be possible Wednesday and Wednesday night in Mississippi and western Alabama.

Trained spotters report tornado in north-central Iowa

News, Weather

September 4th, 2018 by Ric Hanson

ALGONA, Iowa (AP) — Some farm buildings, trees and utility poles in rural north-central Iowa have been damaged by what officials believe was a tornado that briefly touched down.

Kossuth County Emergency Manager David Penton says trained spotters saw what looked like a tornado touch down just southwest of Algona around 3:45 p.m. Tuesday. Penton says buildings used in a hog confinement operation were damaged. He said no injuries had been reported.

The National Weather Service at Des Moines issued a tornado warning for the area that expired around 4:15 p.m. Penton says it will be up to the weather service to confirm whether it was a tornado that hit the area.

August ends up wetter than July

Weather

September 3rd, 2018 by Ric Hanson

(Radio Iowa) — State climatologist Justin Glisan says the month of August brought much-needed rain across the state.  He says we were an inch below average for rainfall in July and as August winds down, we are about six inches about normal. Glisan says that’s good for the state — especially in the southern areas that have been in drought conditions for some time. In Atlantic, we received 8.85-inches of rain in August, which was nearly five-inches greater than normal. The temperature in August state-wide ended up around one-half degree above normal — though the highs and lows were not what we usually see in the eighth month. “We typically expect 83 degrees for the high and 61 degrees for the low. Well, this month we’ve been above average for the high temperature at around 91 degrees. But the average low has been 51 degrees,” Glisan says. “So, when you take the average of the two, we are near normal.”

In Atlantic, our average High was slightly more than one-degree above normal, at 84.3-degrees. The average Low was a tad bit cooler than the norm. The rain we did get across Iowa came in large amounts and Fort Dodge got more than 15 inches of rain overall in August. Glisan says the rainfall should be more gentle in September. “We’re starting to get more frontal systems moving across the state. And these are the type of systems that bring gentler steady rains for a few hours, and it blankets the state” according to Glisan. “And that’s when we are typically building up water for the next year.”

He says the forecast models are showing a mix of temperatures and rainfall through September and into November. He says there will be above average temperatures, but equal chances for above or below average temperatures. Glisan says they are seeing a good chance for an El Nino pattern to develop, which would make it a warmer than normal winter.
