An avalanche warning for the Wasatch Mountains near Ogden and the Bear River Range is still in effect until early Wednesday morning.
Following significant snowfall on Christmas Eve, avalanche danger is “high” in the mountains, according to the Utah Avalanche Center.
“Dangerous avalanche conditions exist at all elevations and human triggered avalanches are likely,” the avalanche center said in the warning, which remains in effect until 6 a.m. Wednesday, Dec. 27.
Those traveling in the backcountry should avoid standing under slopes steeper than 30 degrees and have avalanche safety gear on them. This warning does not apply to ski areas where avalanche hazard protections are in place, the center said.
There’s no snow in the forecast for Northern Utah later in the week, but inversion conditions will return to Northern Utah for a few days.
Yesterday's snow provided a white Christmas for most of the N. Utah. It didn't take long, however, for the inversion to set in. PM2.5 number crept up throughout the day. This trend will continue for the next few days. Watch conditions at https://t.co/rz5IK3fCF4. pic.twitter.com/bTJTXmJ4Lk— Utah DEQ (@UtahDEQ) December 26, 2017
The Utah Department of Environmental Quality has issued a mandatory no-burn alert for Wednesday and Thursday in Davis and Weber counties, where the air quality will drop and become unhealthy for sensitive groups.
Residents of Box Elder County are encouraged to take voluntary steps to help improve air quality, which will remain at moderate levels through Thursday.
During mandatory no-burn alerts, people are asked to not use solid fuel burning devices, reduce or stop open burning and reduce vehicle use by consolidating trips. Industries are urged to optimize operating conditions to minimize air pollution emissions.
Those with lung disease, children and older adults, and people who are active outdoors are particularly vulnerable. People in these groups should reduce prolonged or heavy outdoor exertion.
