If the pressure gradient is large enough, the dry offshore wind can become quite strong with gusts reaching speeds of or higher, particularly along and in the lee of the ridges of the Coast Range where the higher wind speed aloft acts like a pump, drawing warm, dry surface air from the windward eastern side up and over the ridgelines.
