Heavy smoke, visible from across the High Desert, is moving up and over the San Gabriel mountains into the Mojave Desert Air Basin. Air quality sensor data shows impacts to ambient (breathable) air quality in Phelan and the immediate surrounding communities. Other areas of the MDAQMD jurisdiction were unaffected as of 3:45 p.m. Thursday. If smoke impacts further areas of jurisdiction, we’ll update this advisory.
At about 3:00pm, Thursday, July 30, 2020 Calfire PIO reported a new incident called the Dam Fire (#DamFire).

As of 4:15pm over 240 acres have burned. 14 aircraft are “in the attack.” Evacuations are in effect North of Morris Dam ot Crystal Lake. Highway 39 is closed.
In any area impacted by smoke:
