At 3:11 p.m. MDT, Doppler radar indicated a thunderstorm producing heavy rain over the Brian Head burn scar, specifically the Panguitch and Clear Creek drainages. Up to one inch of rain has already fallen. Flash flooding is expected to begin shortly. The warning is in effect until 6:15 p.m. MDT for western Garfield County and east central Iron County.

As of 4:38 p.m. MDT, heavy precipitation has come to an end over the warned area however flash flooding may still be occurring due to the 2 inches of precipitation which fell over the previous 2 hours.

Flash flooding will remain over mainly rural areas of western Garfield and east central Iron Counties.

The debris flow can consist of rock, mud, vegetation and other loose materials.

If a debris flow has occurred, it is important to realize that the runout area remains very dangerous. Additional debris flows may occur within minutes of the original flow. Please remain vigilant and be prepared to take swift action.

“Turn around, don’t drown” when encountering flooded roads. Most flood deaths occur in vehicles.

Remain alert for flooding even in locations not receiving rain. Dry washes, streams and rivers can become flooded with raging killer currents in a matter of minutes, even from distant rainfall.

People in the warning area are advised to move to higher ground immediately. Residents living along streams and creeks should take immediate precautions to protect life and property.
