If you live in Utah you know that our winter weather can be unpredictable. We know, however, that we can expect some things to happen -- the blizzard on your morning commute or, worse, the inversion sitting in our valleys for weeks on end.
For some Utahns, this is simply annoying. Fewer outdoor exercise days, no recess for children and eye-and-throat irritation. For others, the cloud of pollution that smolders in our valleys is a serious threat—exacerbating existing health problems—and making the greater Salt Lake area virtually unlivable for some days in the winter months.
