Report: Derecho was one of the most costly severe storms in US history

A report that compares financial damage and deaths since 1980 ranks August's derecho at No. 4 for most costly severe storm with $7.5 billion in damage.


A new report shows that the derecho that struck Iowa in August was one of the most expensive disasters in U.S. history since 1980.

The National Oceanic and Atmospheric Administration reports that the Aug. 10 storm that impacted areas between Iowa and Indiana cost about $7.5 billion in damage and resulted in four deaths.

The report ranks the derecho as the second most expensive disaster this year with Hurricane Laura with $14 billion and 42 deaths. Multiple events are to be determined, such as Hurricane Sally and the California wildfires. It's ranked No. 47 most expensive within the 40-year time period.

Within the category of severe storms, the derecho ranked No. 4 behind the 1995 South Plains severe weather, 2011 Midwest/Southeast tornadoes and the 2011 Southeast/Ohio Valley/Midwest tornadoes.

"A powerful derecho traveled from southeast South Dakota to Ohio, a path of 770 miles in 14 hours producing widespread winds greater than 100 mph," the report stated. "The states most affected included Iowa, Illinois, Minnesota, Indiana and Ohio. This derecho caused widespread damage to millions of acres of corn and soybean crops across central Iowa. There was also severe damage to homes, businesses and vehicles particularly in Cedar Rapids, Iowa. In addition, there were 15 tornadoes across northeastern Illinois, several affecting the Chicago metropolitan area."

The National Weather Service found that four tornadoes touched down in Iowa on that day.

Gov. Kim Reynolds requested almost $4 billion in federal relief in which President Donald Trump has signed off on parts of the aid.
