Stranded hikers and flash flood warning in Utah County

Hikers were stranded in the Utah County mountains amid heavy rains, which are also causing flash flood conditions in nearby Alpine.

Radar showed the heavy thunderstorms dropped about a quarter to half an inch of rain in the area in the course of about 45 minutes, said Steve Rogowski, a meteorologist with the National Weather Service in Salt Lake City. "It would not have been fun to be out in that," he said.

Utah Search and Rescue crews worked Thursday evening to reach hikers on Dry Creek Trail, a three-mile trek that begins at Granite Flat Campground, according to dispatchers. Just after 11 p.m., the Lone Peak Fire Department tweeted that rescuers had reached the hikers and no one was reported injured.

Meanwhile, Lone Peak Police Department shut down Grove Drive at Alpine Boulevard because of flash flood conditions, according to a tweet. While officers later reopened Grove Drive, homes in the area of Alpine Boulevard "have been effected by some flooding," the police department wrote.

The National Weather Service had issued a flash flood warning at 9:55 p.m. for north central Utah County, especially the Quail burn scar next to Alpine. The warning lasts through 1 a.m. Friday.

The Salt Lake Tribune will update this story as more information is available.
