NWS Confirms Three Tornadoes in Clark County from August 11 Storms
CLARK COUNTY, OH – The National Weather Service (NWS) in Wilmington has confirmed three separate tornadoes occurred in Clark County during the severe storms on Tuesday, August 11, 2026.
NWS meteorologists conducted damage surveys throughout the county with assistance and coordination from the Clark County Emergency Management Agency. The three confirmed tornadoes include:
EF0 – North of Springfield: Estimated peak winds of 80 mph, a 4.5-mile path, and maximum width of 150 yards. The tornado began approximately 2 miles east-northeast of Tremont City and traveled east-southeast toward Catawba. Video showed the tornado moving through a manufacturing and trucking facility on Urbana Road, where a semi-trailer was flipped. Additional tree damage was documented along Willow Road and near Moorefield and Mechanicsburg roads.
EF1 – East of Springfield: Estimated peak winds of 100 mph, a 9.1-mile path, and maximum width of 200 yards. The tornado began near Ogden Road, Old Columbus Road, Ventura Avenue and Heatherwood Avenue and continued southeast toward South Vienna. Damage included downed trees, damage to homes and heavily damaged barns.
EF2 – South of Catawba: Estimated peak winds of 115 mph, a 3.5-mile path, and maximum width of 400 yards. The tornado passed just south of Catawba, destroying outbuildings and causing significant damage to a residence where the roof was removed and an attached garage was destroyed.
No injuries or fatalities were reported from any of the three tornadoes. NWS also determined that some damage throughout the affected areas, including damage within the Village of Catawba, was caused by straight-line winds.
“This is a great reminder to have multiple ways to receive alerts, warnings and emergency information,” said Clark County EMA Director Michelle Clements-Pitstick. “No one system is absolute. Severe weather can develop quickly, and having multiple ways to receive warnings gives you the best opportunity to receive critical information and take action.”
Cleanup Assistance
Residents who still need assistance cleaning up damage from the August 11 storms can contact the Ohio Severe Weather August 2026 Crisis Cleanup Hotline at (740) 207-2397.
Crisis Cleanup connects residents with volunteers from local relief organizations, community groups and faith communities who may be able to assist with trees, debris, tarping and muck out.
All services are free, but assistance is not guaranteed due to the overwhelming need throughout Ohio. The hotline will remain open through Friday, August 28, 2026.
Residents should also check with their township, city or village for debris and brush removal information. Cleanup resources, debris information and other storm recovery updates have been posted on the Clark County Emergency Management Agency page.
The NWS advises that its storm survey information is preliminary and subject to change pending final review.
