SALT LAKE CITY (AP) Breathing is finally a little easier in several of Utah's metropolitan counties.

After several days of haze, the Utah Department of Environmental Quality has lifted health advisories for Salt Lake, Davis, Utah, Weber and Cache counties.

Winter inversion conditions had trapped pollution near the valley floor for nearly a week, prompting state air quality officials to urge residents even healthy ones to reduce exertion outdoors.

Because of shifting weather patterns, the DEQ has issued "green" air quality conditions for those counties, which lifts the health advisories. Moderate conditions are expected to last at least until Tuesday.
