Event narrative (NOAA)
A 10-year-old boy was killed and his 5-year-old brother had to be rescued as a burst of heavy rain at Zion National Park caused flash flooding. The boy was hiking with his family when the storm came through. The boy and his brother ran ahead and reached a part of the trail where water was flowing across. They attempted to cross in the narrow canyon but were swept away. The older boy was swept over the ledge falling more than 100 feet, while the younger boy was able to hold onto a tree before being rescued.
