March 31st 2023 Severe Storms

Overview

An intense storm system tracked across the state of Iowa on Friday, March 31st. This system pulled unseasonably warm and moist conditions into the Midwest, which coupled with a very favorable wind profile, and created quite the volatile environment for severe thunderstorms. This produced several long lived supercells which developed across central Iowa during the afternoon. The storms were prolific hail producers along with a few reports of wind damage as they moved rapidly northeast. Eventually, the storms produced a few tornadoes before exiting into eastern Iowa.

Tornado - Northeast Wapello County

Date	3/31/2023
Time (Local)	3:37 PM
EF Rating	EF-2
Est. Peak Winds	135 mph
Path Length	8.1 miles
Max Width	TBD
Injuries/Deaths	Unknown/0
Summary: Note This Tornado Path extends into Keokuk County and that survey will be sent by the NWS Quad Cities. This survey only covers the Wapello County Portion of the tornado track. Long track tornado began in Wapello County northeast of Ottumwa then tracked northeast into Keokuk County. The primary damage in Wapello County consisted of three homes and one hog confinement facility. The first home lost the entire roof and one external wall. The first failure point was likely the wind entering and lifting the garage which then led to failure of the roof. The home only had straight nailed connections to the external walls spaced every 18 inches and less to the roof. An unoccupied mobile home on the property was not well anchored and rolled to total destruction. This location was rated 110 mph and EF-1. Two well anchored hog confinement buildings were totally destroyed and were rated EF-2. The tornado then impacted a location with a well built 2 story brick house. The house suffered some roof and window damage and a loss of a garage door but sustained little other damage. Other damage indicators at the site suggested EF-1 winds. Total destruction of a house occurred just prior to the tornado exiting the county. This older house sat unanchored to the concrete block basement. The house was pushed off the foundation and crumbled. Some trees near the house and a propane tank were mostly left with little damage. A larger tree directly next to the house on the wind side had several large limbs removed. Due to all of these reasons, the wind at this location has been rated at 135 mph, or high end EF-2.
