 An alleged wrong-way driver was arrested in St. George after mowing down three signposts on Red Hills Parkway. With temperatures above 100 degrees, gusty winds up to 35 miles per hour, and humidity levels as low as 9%, the National Weather Service has issued another fire weather watch through 9 o'clock tonight. And a semi-truck overcorrected and rolled, causing a brief closure of I-15 early Sunday morning.
