Want to escape the pollution-trapping air inversions of northern Utah's urban valleys this weekend? You could trek to the easier breathing of the state's mountains.
But if you do, the Utah Avalanche Center warns that the danger of potentially deadly backcountry snowslides will be elevated. Indeed, forecasters issued a Special Avalanche Advisory for the northern Wasatch Front and its sister peaks, especially for their steep west-to-north-to-east-facing slopes.
Strong valley inversions continued, prompting mandatory air action directives including bans on solid-fuel burning device use, along with outdoor open burning of any kind, restricted automobile travel and requests that industries minimize emissions in Salt Lake, Cache and Davis counties.
