July 14th, 2023 by Ric Hanson

Harrison County, Iowa – The Harrison County Emergency Management Agency and National Weather Service has updated information on a tornado that affected the County, this week. On Wednesday, July 12, 2023, at approximately 5:21 am, the National Weather Service in Omaha, Nebraska issued a tornado warning for Harrison County residents. The storm system which promoted the warning was located just west of Tekamah, Nebraska. This storm system moved rapidly through Harrison County with winds predicted to be destructive at 80 mph or greater.
City officials and Harrison County Emergency Management began taking several reports of damage throughout Harrison County. Although many residents in Harrison County experienced straight-line winds, preliminary damage assessment teams in Harrison County along with the National Weather service report at least one EF2 tornado that impacted residents in rural areas of Harrison County. The tornado is believed to have started southeast of Logan on Overton Avenue and 286th Street and continued south to southeast for approximately 9.25 miles before lifting in the area of 305th Street and Upton Avenue.
Harrison County Emergency Management Coordinator, Philip Davis, states “Once the winds reached a destructive level, the Harrison County dispatcher activated our outdoor warning system warning residents to take shelter as this storm was moving through the area at speeds of close to 80 mph. At one point all of Harrison County except one small portion in the north east corner of the county was under a severe thunderstorm warning with destructive winds likely to occur.”

Davis reports that where the tornado first developed, one house located at 2768 286th Street took a direct hit from the tornado and the structure sustained heavy damage. According to Coordinator Davis, “There were also several other houses and farm buildings which had significant damage showing just how powerful this system was.” Harrison County EMA reports that there are no reported injuries or fatalities from this storm system and tornado as residents took shelter in their homes.
Coordinator Philip Davis stated, “This is Iowa and we as Iowans come out to help wherever it may be needed. It was amazing to see just how many people have shown up and offered support to our residents so quickly after the storm went through. I had no sooner gotten out of one community from assessing damages, and people were already showing up with chain saws and volunteers to help clean up the damage.”
Harrison County EMA continues to assess the damages reported throughout the county. Information collected from the damage assessments will help officials determine the overall impact to our residents and communities. If residents have not reported their damages or do not believe someone has come out to assess their property damage, please report them to Harrison County EMA Coordinator Philip Davis at 712-644-2353 or by self-reporting them at https://report-ia-harrison.orioncentral.com/.

(UPDATE) Early Morning Storm Causes Damage in Cass County

News, Weather

July 13th, 2023 by Ric Hanson

(Atlantic, Iowa) – A severe thunderstorm moved through the area early yesterday (Wednesday) morning. Emergency Management Coordinator Mike Kennon says although there were no reported injuries, widespread damages were evident. Winds in excess of 70 mph knocked down trees, large limbs and created some property damages with power outages. Strong winds also laid down field corn in areas.

While performing Damage Assessments, Kennon noticed that some damages were more severe, very concentrated and seemed to run in a line. A drone was deployed and found that his suspicions were correct. There is a clear path of damage that runs along 4th Street in Marne to a cattle feeding operation at 580th and Eastland Road and ends southeast of the intersection of Eastland Road and 590th. This line is nearly 3 miles long. Similar damage was also noticed in the City of Cumberland and in a couple of other rural locations in Cass County.

Drone picture taken by Cass County Sheriff’s Deputy, Ben Bartholomew.

Mike Kennon was interested in what the National Weather Service thought of this, so he submitted pictures and the drone video footage for their evaluation. Rod Donovan of the NWS-Des Moines said, “ It certainly appears there may have been some spin up circulations along the leading edge of the storm. Likely the radar beam started overshooting these features, so they were quite shallow features.”

The National Weather Service does not currently plan to perform a preliminary storm survey at this time.
