Utah storm facts

  • StormAuditor's analysis of NOAA and National Weather Service records found 2,234 deduplicated storm events (wind, hail, tornado, and flood; NWS warning products included) in Utah in the 12 months ending October 21, 2026.
  • Storm activity touched 29 of 29 Utah counties over that period.
  • The most impacted county in Utah was Tooele, with 272 events.
  • The busiest day by event count in Utah was December 17, 2025, with 188 events.

Utah storm activity at a glance (last 12 months)

StormAuditor's consolidated public record currently shows 2,234 storm events impacting 29 of Utah's 29 counties in the trailing 12 months: 1,589 wind events, 285 hail events, 12 tornado events, 348 flood events. Every count includes NWS warnings as well as observed reports, so tornado events mean tornado warnings and reports, not confirmed tornadoes.

Events are fused from National Weather Service warnings and Special Weather Statements, observed Local Storm Reports, official NCEI storm records, and FEMA disaster declarations, then consolidated into a single event table under the published methodology.

Wind covers thunderstorm and non-thunderstorm wind alike, so these counts measure something different from the NCEI entry counts in the history section below; the two are not comparable year to year. State totals also count NWS Special Weather Statements (radar-indicated hail or gusts below warning level); city pages leave those out.

Busiest days in Utah by event count

Ranked by the number of 12-month events, NWS warnings included, so a day with many warnings can outrank a day with larger hail.

Most impacted counties

Events of every type for each county — wind, hail, tornado and flood, NWS warnings and Special Weather Statements included. City pages count wind and hail events only, so a county number on a city page is never higher than the number here.

Additional activity recorded under other NWS area names (forecast zones, tribal lands, and former census areas): Great Salt Lake Desert and Mountains (7) · Tooele and Rush Valleys (6) · Mountains (5) · Uinta Basin (5).

How these numbers are counted

The storm numbers on this page are counted in four different ways, plus the free address check. Each answers a different question with its own size cutoffs, area and time span, so compare numbers within one group, not across groups.

  • Storm days (latest hail and wind): A day in the last 12 months when at least one report anywhere in Utah showed hail 0.75 in. or larger or wind of 45 mph or more (StormAuditor screening thresholds). Reports are NWS storm reports from spotters, the public and officials, plus weather-station gusts, which count from 50 mph. A warning on its own never makes a storm day. The "City pages hit" column and each city's last reported hail apply the same rule within 25 miles of the city. The statewide columns count reports inside Utah only. City pages count reports within 25 miles of each city, which can reach into a neighboring state; those values name the other state, so a border city's value for a day can be higher than the Utah value.
  • Storm-date pages (NWS severe): A storm-date page is published only when at least one report or station gust within 25 miles of a city met the National Weather Service severe criteria (hail 1.00 in. or larger, or wind 58 mph or more), at least two separate observations were logged, and the day ranks among the most significant. A storm report that relays an airport weather station's reading (the same station, the same gust and the same time) counts once, as the station reading. Not every storm day gets a page; when one does, the page and the storm-day table show the same largest hail and strongest gust.
  • Events (12-month counts): Events count the Utah storm log: NWS warnings and Special Weather Statements (a lower-level NWS alert), storm reports (wind 50 mph+, hail 0.75 in.+), station gusts, NCEI entries and FEMA disaster declarations, for each county affected, floods included. One event is one place on one day, counted separately for each type (wind, hail, tornado, flood). A weather station or storm-report point counts once a day, at that day's highest reading, however many readings it filed; a place with hail and wind on the same day is two events. NWS warnings and Special Weather Statements count once per county per day, and NCEI entries and FEMA declarations once per place per day. A storm report that relays an airport weather station's reading (the same station, the same gust and the same time) counts once, as the station reading. The same report arriving through another feed (SPC or NCEI) is one record. The most impacted counties list uses this count. City pages count only wind and hail within 25 miles and leave out floods and Special Weather Statements, so city counts do not add up to the state total, and a city page's county count is a wind-and-hail count that is never higher than the same county's number here.
  • NOAA history (since 2010): The official NOAA storm record (NCEI Storm Events) in Utah from January 1, 2010 to the day before the 12-month window starts: hail 0.50 in.+, thunderstorm wind 40 mph+ and tornadoes. It is a separate, older record with its own "storm days" (days with any entry), so its counts are not compared with the 12-month numbers.
  • Free Report Snapshot: A free YES/NO estimate for one address, from radar and wind analysis at the property rather than area reports, at the same screening thresholds: hail 0.75 in. or wind 45 mph.

Utah hail and wind history in NOAA NCEI records, 2010–Oct. 2025

This section covers January 1, 2010 through October 20, 2025. Storms from October 21, 2025 on are in the 12-month summary above, so no date is counted in both.

Utah storm days by year, 2010–Oct. 2025 (NOAA NCEI Storm Events).

Wind is the more common entry — 2,190 thunderstorm wind reports to 291 hail reports. In all: 2,512 NCEI Storm Events entries in Utah, spread over 473 storm days.

The largest hail in these records for Utah was 2.00 in. (hen-egg size), reported in 2010, 2013 and 2021 — most recently on August 17, 2021 in Beaver County. Hail of 2 inches or more appears in 3 different years of this record, the latest being 2021. Measured thunderstorm gusts topped out at 93 mph (Tooele County, June 19, 2017). NCEI also lists 31 tornado entries in Utah — one entry per county a tornado crossed.

Hail peaks in August (29% of all hail reports); thunderstorm wind peaks in July. December through February accounts for 4 storm days.

Storm days ranged from 13 in 2018 to 53 in 2024. Across 2022–2024, Utah averaged 45 storm days a year, above the 15-year average of 29. The latest five full years (2020–2024) averaged 37 storm days, up from 26 in 2010–2014.
