Utah's days of "Red," or unhealthy air alerts are numbered, and that number appears to be one.
The Utah Division of Air Quality rated most of the state on Wednesday as "Red," meaning all burning was banned and the elderly, young children and those with compromise lung or heart health were urged to avoid outdoor activity. Motorists were asked to use mass transit or work from home rather than add to the inversion-worsened smog plaguing the state's urban valleys.
However, on Thursday morning that cold Pacific air begins to flow out of the Northwest and into the Wasatch Range. The National Weather Service has issued a winter storm watch for much of the state, from Logan running south through Ogden, Salt Lake City and Provo to near Escalante, west to the Nevada border, southwest to St. George, and also to sections of eastern and southeastern Utah.
