The tornado’s path was an average of 300-yards wide, and 7.1-miles long. When it initially touched down, it produced sporadic tree damage near the intersection of County Road E-60 to L-14, in Monona County. The twister moved northeast and hit a farmstead, downed power lines and destroyed a grain bin.

It continued northeast through the Loess Hills, producing varying degrees of tree damage, before crossing County Road E-54 and 277th Street, where it destroyed more trees and a few outbuildings. The twister continued its trek northeast across 258th Street, where it hit another farmstead, tearing-off part of the roof off of a house, destroyed some outbuildings and several more trees.

Before it dissipated, the tornado crossed another road and knocked down power lines. No injuries were reported. Officials say the EF-1 twister produced peak winds of up to 90-miles per hour. An EF-1 tornado typically has wind speeds ranging from 86- to 110-mph.

Council Bluffs launches 24-7 flooding hotline

News, Weather

June 8th, 2011 by Ric Hanson

Plenty of rumors are floating about the looming flooding in Council Bluffs and the city is taking steps to separate truth from fiction. Art Hill, a spokesman for Council Bluffs, says they’re launching a 24-seven flooding hotline so people can get answers to any questions right away.

“We are establishing an information line,” Hill says. “It’ll always be staffed by a person to relate information they’ve been hearing and whether or not it’s correct.” He says the city is also updating its website constantly with the latest flood data. Hill urges Council Bluffs residents and business owners to register on the city’s Code Red notification system.

“If, geographically, your home or business is in a location that might be impacted in some way, you’ll get either a phone call or a text telling you about it,” he says. Hill says officials want to make sure all residents with special needs get help in case there is an evacuation due to flooding — or some other emergency.

“Whether it’s because of limited mobility or age, they (should) register with the city and in the event of an evacuation, we’d have the information.” The information line is (712) 328-4672 and the website is:

DES MOINES - The suspension of recreational boating by the U.S. Army Corps of
Engineers on the Missouri River between Sioux City and mile marker 550 where Iowa,
Missouri and Nebraska meet includes backwaters of the river.

The Iowa Department of Natural Resources has also closed boat ramps at Blue Lake,
Browns Lake and Snyder's Bend because of the flooding occurring on the Missouri

"This is an extremely dangerous situation, not only for recreational boaters, but
for rescuers if a problem should occur on the water," said Robert Garrison, chief of
the law enforcement bureau for the Iowa Department of Natural Resources.

The DNR closed all state run boat ramps on the Missouri River on June 2nd.

According to the U.S. Army Corps of Engineers, violation of the order establishing
the suspension of recreational boating in the designated area can result in a
maximum civil penalty of $40,000 for each violation.

A "willful and knowing" violation of the no-boating order can also result in a
felony charge punishable by a fine of up to $250,000 and/or a prison sentence from
five to 10 years.

Iowa records 13 tornadoes, extreme high/low temperatures in May

News, Weather

June 1st, 2011 by Ric Hanson

The month of May in Iowa was marked by severe storms and drastic swings in the temperature. State Climatologist Harry Hillaker says 13 tornadoes touched down last month across Iowa. “Which is actually average for us this time of year,” Hillaker said. Eight tornadoes hit parts of western Iowa on May 11th.

The town of Lenox sustained the most damage, but no one was killed or seriously injured. Five more tornadoes ripped through rural areas of northeast and east-central Iowa on May 22. Iowa’s already recorded 37 tornadoes in 2011. “That already exceeds the total for last year and (2009),” Hillaker said. “The normal annual total is 48, so we’re not quite to that point.”

In 2008, Iowa recorded 120 tornadoes that killed 13 people – primarily in Parkersburg and New Hartford and at a Boy Scout camp in western Iowa’s Harrison County. Hillaker says Iowans should remain on alert for severe weather in the weeks to come. “June, on average, is our busiest month of the year for tornadoes in Iowa,” Hillaker said.

The statewide average temperature in May turned out to be “normal,” according to Hillaker, but the month included extreme heat and cold. The hot spot was Jefferson – which hit 100-degrees on May 10. Just one week earlier, on May 3, the coldest temperature of 20-degrees was recorded in both Spencer and Sibley. Hillaker says the statewide average rainfall was 5.2 inches. Normal rainfall for May is 4.25 inches.

Here in Atlantic, we received 4.17-inches of rain in May, which is three-tenths of an inch above normal. Our average High was 72-degrees, which is 10-degrees cooler than normal. The hottest day was on May 10th, when we hit 97-degrees. The average low was 48, which is about average for the month.
