For the second day in a row, smoke from a wildfire in Arizona enveloped the Pikes Peak region in haze, prompting state health officials to issue a smoke health advisory Friday that will remain in effect through early Saturday.

The advisory was issued at 2 p.m. for the San Luis Valley, northeast to El Paso County and south to Las Animas County. Cities and towns covered by the warning include Colorado Springs, Cañon City, Walsenburg, Pueblo, Trinidad, Westcliffe and Alamosa.

The advisory will remain in effect until 4 a.m. Saturday.

Emmett Malone, meteorologist with the Colorado Department of Public Health and Environment, said initially it appeared that a cold front would keep the smoke higher than the day before. However, later in the day it mixed in with the air close to the ground creating the haze that has shrouded the region for two days, he said.

The smoke is from the Wallow fire burning near Show Low, Ariz. Fires burning near Trinidad haven't contributed to the haze, according to the health department, because winds are carrying that smoke away from Colorado Springs.

On Saturday, Malone said, the winds are expected to change direction and should carry the smoke from the Arizona fire south of Colorado Springs.
