The map shows smoke created by wildfires. It appears that the southwest and south portions of the United States are affected by smoke, with much of it coming from the Wallow fire in Arizona, fires in Mexico, and others in Louisiana, east Texas, and Arkansas. The states of New Mexico, Kansas, Colorado, and parts of Oklahoma and Texas are being hit the hardest.
The red dots are fires, while the smoke is green (thin), yellow (moderately dense), and purple (dense).
