Smoke has filled the Grand Valley, drifting in from fires around the region, some from as far away as California.
11 News has spoken with National Weather Service officials who say the smoke is coming from fires burning in California as well as Southern Utah and a blaze near Nucla.
They say it's caught up in the wind pattern and is caught in the valley. No word on when it will blow out.
More on what it means tonight on 11 News at 5:30 and 10 p.m. with Reporter Chiara Lotierzo.
