It’s November — and time for some heavy weather [Update]

As if on cue, a spate of wet, windy and (in some places) snowy weather is coming to the North Olympic Peninsula and Western Washington (the latter geography is made more important because of Thanksgiving travel).

Here are weather advisories straight from the National Weather Service.

Port Angeles, Sequim, Port Townsend and most of the North Olympic Peninsula; Western Washington:
