The National Weather Service reported an air quality alert at 12:43 p.m. EDT on Sunday in effect until Tuesday at noon EDT for Chippewa and Mackinac counties.

The National Weather Service said the alert will be in effect until Sunday morning in the Santa Clarita Valley and Saturday night in parts of Los Angeles, Ventura, San Bernardino, and Riverside counties.

Air quality has taken a serious hit across the United States as a two-fold blow of wildfires in the West and in Canada have sent smoke pouring across large sections of the country — a problem that’s set to linger for days.
