Air quality Action Day continues in Utah; PM2.5 code orange also observed in Central California and in Southern Oregon

Action Day was once again issued to a few cities in Utah (Logan, Ogden, Provo and Salt Lake City - bottom, right) as well as in Chico, California. For tomorrow, there is an Action Day forecast for the same cities in Utah. In addition to those cities, code orange in terms of PM2.5 was observed in the first hours of the day in Central California (top, left) and then again in the afternoon, and also in Southern Oregon.
