Asthmatics, take note: the haze hanging over Sacramento is made up of wildfire smoke and marine air, two factors that clutter the sky with unhealthy particulate matter.
The smoke has traveled more than 300 miles from three separate fires scattered throughout Oregon, blown into the Central Valley by nightly winds, said Christina Ragsdale, a spokeswoman for the air quality district.
The Sacramento Metropolitan Air Quality Management District has declared the haze moderately unhealthy based on a measurement of particulate matter in the air.
The trio of fires contributing to the haze are:
The Whisky Complex: 1,649 acres. The Douglas Fire Complex: 13,400 acres. The Labrador fire: 1,700 acres.
The majority of Sacramento residents won't notice the effects, but if conditions get any worse people with asthma or other respiratory problems might want to refrain from rigorous exercise outside, Ragsdale said.
"The thing about air pollution is that it's different for everybody, " she said.
The haze is also made up of marine air blown into the valley by the Delta Breeze, said Holly Osborne, a meteorologist from the National Weather Service.
Although the combination of smoke and ocean air has cut visibility in half, it still doesn't endanger motorists or airplane pilots.
Air conditions should get better by the afternoon as the Delta Breeze pushes the hazy air back up the valley, Osborne said.
