It is mid-day in the San Francisco Bay Area but the skies are dark and orange from high altitude smoke.
In previous weeks there was low altitude smoke which made for low highway visibility. However, today the light levels are like just before sunset.
Satellite pictures show dense smoke covering nearly the entire state of California. Here is a picture from Daniel Swain.
There are fires all over California. There is smoke from those fires and fires in Oregon.
