Over 15,000 firefighters are assigned to 83 active wildfires in the United States which have burned a total of about 942,000 acres. In addition to fire overhead and incident command post personnel, they are staffing 369 hand crews, 678 fire engines, and 141 helicopters. So far this year over 6 million acres have burned in the country.
As you can see below, the air quality compromised by smoke is not getting any better. Again, four cities in Idaho and Washington are four of the top five locations in the country with forecasts for the worst air today.
