The Museum Fire burning near Flagstaff is pumping large amounts of smoke into the atmosphere. Efficient summertime ventilation has kept health impacts to a minimum thus far as the plumes are dispersing as they travel north and east of the fire. So far, there have been no health advisories issued by Arizona Department of Air Quality (ADEQ) or the National Weather Service. This can change with the varying conditions and those with sensitivities to smoke are encouraged to stay alert and informed. Monday night, light northerly winds are forecast to bring smoke into Flagstaff communities.
