SALT LAKE CITY (AP) — A woman who was critically injured and whose stepdaughter died after lightning struck the personal watercraft they were riding in a Utah reservoir is improving.

University of Utah Hospital spokeswoman Kathy Wilets says that Jayleen Reynolds had been upgraded to fair condition Saturday.

Daggett County sheriff's officials say the 49-year-old and her 14-year-old stepdaughter, Brooklyn Reynolds, were riding in a remote area of Flaming Gorge Reservoir around noon Friday when the lightning struck.

The teen was pronounced dead.

Jayleen Reynolds was airlifted to the hospital with critical injuries.

Sheriff's spokeswoman Susie Potter says the teen's father, who was on another watercraft, was treated at the scene for shock.

The reservoir inside Flaming Gorge National Recreation Area straddles the Utah-Wyoming border and is 200 miles east of Salt Lake City.
