Every year we get calls from panicked clients whose pipes have burst. Colder temperatures have become a regular part of winter in the Pacific Northwest. Even though opening up the outside spigots to a slow and steady drip used to be enough to prevent frozen pipes, it's likely time to consider more permanent cold-weather solutions.
We recommend frost-free hose bibs for all outside spigots, which you can find at the hardware store and install on your own, and insulating any vulnerable pipes, a job any handyperson could take care of for you.
