SALT LAKE CITY -- Gov. Gary Herbert is offering his sympathies and support for Utah residents who were injured or suffered property damage when winds reaching 102 mph toppled trucks, did millions of dollars in damage and triggered at least three serious injuries.
Herbert lauded acts of heroism in a statement Friday, in which he commended emergency workers and others responding to the powerful storm that swept through the western U.S. Thursday.
"An event of this magnitude requires us all to cooperate and step up," the Republican governor said. "I also urge Utahns to demonstrate Utah's culture of volunteerism and ask you to assist those who have been affected by the storms."
At least three people in Utah were seriously hurt in the storm.
Salt Lake City police confirmed a 13-year-old boy was in critical condition Friday with severe head injuries after being hit by a falling tree branch while walking his dog. A passer-by found the boy unconscious about 7 a.m. Thursday, and emergency workers transported him to the hospital.
Authorities say his parents later called police to report him missing when the dog returned home alone. Police linked the two cases to identify the boy.
South Davis Metro Fire Chief Jim Rampton said two adults were released from the hospital after suffering carbon monoxide poisoning Friday morning in Bountiful.
Rampton said a passer-by out for a morning walk heard calls for help and found the two collapsed near a partly open front door. Authorities traced the toxins to a generator next to the house that was being used amid power outages.
Fire officials warned people not to use generators indoors.
Rocky Mountain Power officials said about 300 crew members were working to restore power to about 6,000 people who were still without electricity by late afternoon Friday. Outages centered in Davis and Weber counties, with more than 50,000 customers losing power at the peak of the storm.
The American Red Cross had opened several warming shelters to care for residents without heat and light. Some waste companies were also allowing residents to dispose of tree debris for free.
Herbert said he directed his cabinet to deploy full state resources as needed in the storm's aftermath. He said state officials plan to assess damage and determine where more public resources are needed.
