Storm Spotter Training in Menlo March 20th

Weather

March 11th, 2019 by Ric Hanson

The Adair & Guthrie County Emergency Management Agency will be hosting a Storm Spotter Training Session in the Community Building next to City Hall in Menlo on March 20, 2019 at 7:00 PM. This training session is open to the all county responders and the public. The training session is free.

The session normally last two hours and acquaint you with basic information on the formation of severe weather storms and how they function. What to report, as well as how and where you should communicate the information. After training, you may register as a severe storm spotter on the National Weather Service web site or at spotter training sessions. This would enable meteorologists to call you to get real time information and to confirm severe weather activity indicated by Doppler radar images in your vicinity.

According to Robert Kempf, Emergency Management Coordinator, “One person could make the difference in the potential injuries or deaths from a severe storm or tornado. By being aware of the possibility of severe weather or tornados in your area, you can react to rapidly changing weather conditions and improve you, your family and your community’s safety in such an event. As a trained spotter serving your area and providing the National Weather Service with severe storm reports, meteorologists can correlate your real‑time information of storm activity with the data they are receiving by radar”, according to Robert Kempf, Emergency Management Coordinator.

Why does National Weather Service need severe weather reports from trained weather spotters? The Doppler radar cannot detect what is really happening at ground level, especially the greater the distance the weather event is from the radar site. The radar is designed to look into the heart of storm clouds and their surroundings to detect wind currents and other storm structure clues that suggest a storm is or will become severe. With accurate ground truth reports along with radar images and other meteorological data available to weather service personnel, the decision can be made whether to issue a storm warning to the public.

With timely reports of severe storm activity volunteered by citizens and data from improved technology at the National Weather Service offices, the numbers of injuries and deaths in Iowa from severe weather can be minimized.

The National Weather Service reports widespread rain across Iowa remains on track for Tuesday through Thursday, where a swath of 1 to 2 inches of rain can be expected. Thunderstorms are possible as well, resulting in locally higher amounts approaching 3 inches, especially over western portions of Iowa. In addition to the rainfall, warmer temperatures will melt a good portion of the snow pack today through Wednesday resulting in significant runoff and potential river flooding mid to late week and into the weekend. The potential for ice jams exist as the runoff, swelling rivers, and warmer temperatures look to break up the river ice and lead to some localized flash flooding.

Flood Watch issued for far west/southwest Iowa Counties, beginning 1-a.m. Wednesday

Monona-Harrison-Shelby-Pottawattamie-Mills-Montgomery-Fremont-Page Counties: A FLOOD WATCH IS IN EFFECT FROM LATE TUESDAY NIGHT/EARLY WED. EVENING THROUGH WEDNESDAY EVENING.

The National Weather Service in Omaha/Valley has issued a  Flood Watch for portions of Iowa and Nebraska from 1-a.m. Wednesday through 7-p.m. Wednesday.

* A strong storm will bring warming temperatures and 1 to 3 inches of rain to the region during the middle of the week. This will result in an increased risk of river flooding, do to the unusual
combination of heavy rain, snowmelt, saturated or frozen soils, and thick ice cover on area rivers. Significant and rapid river level increases are possible do to runoff or localized ice jams. Anyone with interests along or near area rivers should continue to monitor the forecast and river levels closely.

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 action should flooding devel

‘Major-level flooding’ forecast for many Iowa tributaries this spring

News, Weather

March 8th, 2019 by Ric Hanson

(Radio Iowa) — More reports are trickling in which predict Iowa could face a serious flooding problem this spring. The U-S Army Corps of Engineers is the latest agency to issue a warning about the potential for “major-level” flooding, based on the snowpack in the Rocky Mountains. Kevin Low, a hydrologist with the Missouri Basin River Forecast Center, offers this update. “Snowpack conditions in the mountains can be categorized as near-normal to a little bit above normal,” Low says. “By this point in the winter, we’ve accumulated usually about 80% of the seasonal peak snow-water equivalent in the mountains, so we’re getting close to seeing what we’re going to see.”

While the mountain snowpack may only be slightly above normal, there’s a lot of snow on the ground across the region which will soon melt as well. Low says the Corps of Engineers is putting out a series of long-range flood outlooks for the upcoming three months. “These outlooks call for major-level flooding along many of the tributaries in South Dakota and in Iowa,” Low says. “Specifically, we are projecting major-level flooding along the Big Sioux in South Dakota and in Iowa, and on the Floyd and Little Sioux rivers in Iowa.”

The river that comprises the border between Iowa and Nebraska may also soon experience a level boost. “The Missouri River downstream of Gavins Point Dam is also expected to see moderate-level flooding this season,” he says. Low says localized flooding due to ice jams is also possible over the next few weeks.
