Thursday afternoon, a Flash Flood warning was in place for Utah County, but the warning was lifted later Thursday evening.
The warning for Utah County affected the Pole Creek area near the Bald Mountain burn scar in the south-central part of the county.
"Excessive rainfall over the burn scar will result in debris flow moving through the Pole Creek burn area draining onto Highway 89 near Birdseye. The debris flow can consist of rock, mud, vegetation and other loose materials," the warning said. "A debris flow is expected to impact U.S. 89 near Birdseye between mile markers 306 and 311. People traveling through this area should be prepared for debris on the highway in both directions. Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles."
The warnings call attention on people who are outside camping, hiking or near bodies of water.
"Dry washes, streams and rivers can become raging killer currents in a matter of minutes, even from distant rainfall," the warning said. "It is important to know where you are relative to streams, rivers, or creeks which can become killers in heavy rains. Campers and hikers should avoid streams or creeks."
As of 7:30 p.m. Thursday, the warning is expected to expire by 8:30 p.m.
