Episode Narrative Afternoon thunderstorms continued across Utah in the middle of August. The strongest of these thunderstorms most commonly produced flash flooding in southern Utah, but isolated occurrences of severe winds and a tornado were also observed.
Event Narrative After an estimated 1.25 inches of rain fell over Zion National Park, flash flooding was reported in Spry Canyon, Pine Creek Canyon, and Echo Canyon. The heavy rainfall also caused rocks to fall onto State Route 9, between the switchbacks and the tunnel, which impacted traffic through the park.
