Damage, injuries and deaths
NOAA's Storm Events database, which records damage and casualties, runs through July 31, 2026. NCEI adds each month about three to four months after it ends; this day will show here then.
NWS Tornado Damage Surveys for August 13, 2026
National Weather Service survey teams mapped 2 tornado paths from this storm day (1 EF1, 1 EFU), 2 miles in all. The map above draws each surveyed path as the NWS mapped it, colored by the EF rating of each stretch, in place of the straight start-to-end line.
| Rating | Peak wind | Path length | Max width | Deaths / injuries | On the ground | Surveyed by |
|---|---|---|---|---|---|---|
| EF1 | 100 mph | 1.0 mi | 300 yd | 0 / 0 | 23:41–23:43 UTC | NWS Salt Lake City |
| EFU | – | 0.9 mi | 10 yd | 0 / 0 | 22:46–22:50 UTC | NWS Cheyenne |

Survey data are preliminary and can be revised; NOAA's official record is Storm Data (NCEI). Paths are simplified to about 30 m. Times are when the tornado was on the ground, in UTC.
