Rare Mountain Tornado Strikes Northern Utah
By Drooid · · How we work
Core Event
On Friday, September 18, 2026, a strong tornado touched down on the mountainside east of Fruit Heights in Davis County, Utah. The National Weather Service (NWS) office in Salt Lake City issued a tornado warning for parts of Davis, Morgan and Weber counties, and radar indicated a rotating funnel that lofted debris up to 4,000 feet. The vortex made brief ground contact near a ridgeline summit close to Francis Peak at roughly 7,500 feet elevation. The area was sparsely populated, and no structural damage from the tornado itself was reported.
Background & Context
Utah averages about two tornadoes per year, making any warning uncommon. The September 18 event was the third tornado reported in the state in 2026 and only the second warning issued by the Salt Lake City NWS office this year; the first, for Tooele County, was the first such warning from that office since 2011.
Timeline
- Early afternoon – Radar detected broad rotation north of the Great Salt Lake.
- ? 1:30 p.m. – Rotation tightened, forming a mesocyclone over Interstate 15 in Farmington.
- Just before 1:45 p.m. – NWS issued a tornado warning for the affected counties.
- ? 1:52 p.m. – A preliminary report logged a tornado touchdown about 2 miles east of Fruit Heights, near the Francis Peak ridgeline.
- 2:15 p.m. – The tornado warning expired; a severe thunderstorm warning remained for central Morgan and south-central Weber counties.
Data & Statistics
- Tornado count 2026: third reported in Utah.
- Touchdown elevation: ~7,500 feet.
- Debris loft height: 4,000 feet.
- Wind gusts: over 60 mph.
- Hail size: half-dollar-size and ping-pong-ball-size hail observed.
Official Statements & Responses
NWS meteorologist Brittany Whitlam called the event a “strong” tornado and said an Enhanced Fujita (EF) rating will be assigned after a ground survey. Matt Johnson of KSL explained that a low-pressure system from the Pacific Northwest collided with subtropical moisture, creating wind shear sufficient for severe thunderstorms and the tornadic signature. The NWS advised residents to seek shelter in basements or interior rooms on the lowest floor of sturdy buildings and to stay away from windows.
On-the-Ground Reports
Residents in Davis, Weber and Morgan counties reported a funnel cloud and captured video of swirling clouds and heavy rain. Social-media footage showed the tornado briefly near the summit, while hail struck a vehicle in Kaysville, cracking the windshield. No urban structures were directly impacted by the tornado itself.
Conflicting Reports & Gaps
Sources differ on the exact timing of the tornado warning: one account cites issuance just before 1:45 p.m., another references a 2:15 p.m. warning time. A Deseret article indicated uncertainty about whether a tornado actually touched down. No damage assessment specific to the tornado has been released, leaving the eventual EF rating unclear.
What’s Next
Meteorologists expect the severe thunderstorm threat to persist later Friday, with scattered storms possible into the evening. Isolated showers are forecast for Saturday, followed by cooler, drier conditions over the weekend. The NWS will dispatch a survey team to evaluate the tornado’s intensity and finalize its rating.
