SALT LAKE CITY — Northern Utah will be rife with dangerous fire conditions until Saturday night.

A red flag warning has been issued until 10 p.m Saturday, Sept. 15, by the National Weather Service of Salt Lake City for most of the state, including Weber, Davis and Box Elder counties.

The NWS issues a red flag warning when “critical fire conditions are either occurring now or are imminent.”

“A combination of strong winds, low relative humidity and warm temperatures can contribute to extreme fire behavior,” the NWS said.

Expect to see southwest wind gusts of up to 40 mph every afternoon through Saturday and low relative humidity in the valleys and mountains.

People should obey all fire restrictions, make sure campfires are completely put out, and should use caution when operating lawn mowers or other equipment as fires will have “the potential to spread rapidly,” the NWS advised.

Areas of Utah saw fires rage on Thursday, with the Pole Creek fire in southern Utah County growing from 4,000 acres to 20,000 acres in less than 12 hours. The fire caused some evacuations in that area of the Wasatch Front, with smoke visible across multiple valleys. Personnel were trying to track the fire’s heat using satellite imagery, according to the incident commander James Turner as reported by the Daily Herald.

An adjacent fire near Payson Canyon, Bald Creek Fire, also burned at least 500 acres so far since it started Aug. 24.
