zero visibility. Visibility will improve later this morning. The
high pressure will weaken temporarily on Tuesday with some
improvement in mixing of the air mass. But stagnant conditions
will likely return at the end of the week and continue through
next weekend.

green... Myrtle Creek... Canyonville... Grants Pass... Cave
Junction... Medford... Ashland.

Precautionary/preparedness actions...

An air stagnation advisory indicates that due to limited movement

A dense fog advisory means visibilities will frequently be
reduced to less than one quarter mile. If driving... slow
down... use your headlights... and leave plenty of distance ahead of
you.
