With Utah gripped by one of its most dangerous wildfire seasons in recent memory, state officials have imposed sweeping restrictions on Fourth of July fireworks ahead of the nation’s 250th Independence Day celebrations, saying the risk of sparking catastrophic new fires is simply too great.

Gov. Spencer Cox acknowledged in a news release Friday the move was an exceptionally difficult one.

“Nothing about this decision was easy,” Cox said. “Utahns love celebrating the Fourth of July with family, friends and fireworks. I do too. But this year is different. We are seeing fire behavior that even our most experienced firefighters say they’ve never witnessed before.”

A historic drought, hundreds of wildfires and unprecedented fire behavior have stretched Utah’s firefighting resources to the brink, leaving little room for additional human-caused ignitions, according to the governor’s office.

More than three-quarters of Utah’s wildfires this season have been sparked by people, state officials said. They warn that an extended drought, bone-dry vegetation and volatile weather have created conditions where a single spark can rapidly explode into a fast-moving, destructive wildfire.
