Santa Clara, the town this property stands in, in 15 storm reports between 1994 and 2021: 6 thunderstorm wind, 3 lightning, 3 flash flood, 2 hail.
The reports record 2 injuries. Each account below is quoted exactly as the forecast office
filed it, from the NOAA Storm Events Database, and each date
opens the federal record of that event.
Two 17 year old males were struck by lightning just outside Snow Canyon High School in St. George. The two boys were waiting for a ride home shortly after school let out; they took shelter from the rain under a nearby tree, where lightning struck and injured them both. CPR was performed at the site, and they were both in critical condition when they reached a hospital in Las Vegas, but both survived and are expected to make a full recovery.
An extended period of moderate to heavy rainfall occurred in southwest Utah on the morning of September 11th, during which 3.24 inches of rainfall was measured in Ivins, Utah. In nearby Santa Clara, an earthen dike (called the Laub Dike) burst, releasing all of the water in the associated retention pond. This water and mud flowed into nearby homes and businesses, damaging both public infrastructure and private properties. A total of $3.8 million in damage was done to public infrastructure, including damage to the dike, streets, and sidewalks. The flood also damaged 16 businesses and 63 homes; some of these buildings had internal damage due to water and mud flowing into them, while other buildings experienced serious structural damage.
Houses and basements were flooded in both Santa Clara and Ivins. In addition, the water flowing over Santa Clara Drive was 1 foot deep and 40 feet wide.
Flooding was reported over the bridge where old US Highway 91 crosses the Santa Clara River. This flooding caused the road to be closed for a few hours in the late morning and early afternoon.
Moonsoon moisture arrived over southern Utah producing heavy rains and wet microburst winds. In New Harmony 2.00" of rain fell in 50 minutes, and flood water depth was two to three feet. The St. George AWOS recorded 0.80" less than 40 minutes which allowed for minor house and street flood. Wind gusts to 60 mph downed power lines and tree limbs. In Hurricane, wind gusts were estimated at 70 to 75 mph. Rainfall of 0.79" in 30 minutes allowed for two to three feet of water to flood State Road 9 between Interstate 15 and Hurricane. In Santa Clara, wind gusts downed tree branches, and 0.25" fell in ten minutes. In Bloomington, several homes and businesses were flooded and wind gusts took down power lines and tree limbs.
