One Utah home was flooded and a retention basin was filled to the brim as Tuesday night's thunderstorms sent mud spilling into Alpine.
A flash flood hit Grove Drive about 7:45 p.m., flooding one house before crews were able to divert the flow around two other houses and down the middle of the street, said Lone Peak Fire Chief Brad Freeman.
Meanwhile a new debris basin over the Box Elder subdivision was filled to capacity, sparing that neighborhood from the .83-inch of rain that fell in just an hour, the National Weather Service reported.
The basin was constructed near the burn scar from last year's Quail Hollow fire.
"We'll be up tonight watching it," Freeman said. More rain was forecast Wednesday.
Meanwhile, a mudslide closed a 10-mile section of State Road 31 in Emery County on Tuesday afternoon, according to the Utah Department of Transportation and the National Weather Service.
UDOT Spokesman Kevin Kitchen said flash flooding in the canyon just east of Fairview caused the closure. Crews were at the scene Tuesday evening working to clear the road, but UDOT estimated the closure could last all night.
Kitchen noted that the flooding occurred in a portion of the canyon that had been scarred by wildfires last year.
The National Weather Service in Salt Lake City issued a flash flood warning for areas near the Escalante River drainage in southwest Utah, including parts of Garfield, Kane and San Juan counties.
