Heavy smoke from several wildfires is drifting across the Central Valley and the foothills. Warnings are out for people to take precautions if they see or smell smoke.
A smoky haze runs from southern Tuolumne County down to Tulare as 4 wildfires continue to burn.
In some areas such as Merced County, ash is falling from the sky.
Maricela Velasquez with the San Joaquin Valley Air Pollution Control District says the smoke and ash can cause health problems.
She says extra caution should be practiced when smoke is particularly visible.
“They’re seeing the smoke, like the ground level, or they’re smelling that smoke or that ash, they need to treat it as unhealthy for everyone,” says Velasques.
She also says the smoke won’t disappear overnight.
“The smoke will actually remain on our valley floor for quite some time and may still remain until we get strong winds to push the stuff over the ridges.”
