The winds out of the west are expected to be between 15 and 25 mph in those two areas, with gusts potentially reaching 35 mph Wednesday afternoon, forecasters said. Light winds are expected in coastal areas Wednesday, while gusts in the western valleys could reach 25 mph.

A wind advisory will be in effect from 10 p.m. Wednesday through 6 a.m. Thursday in the mountains and deserts.
