It's already in the teens here in Wash. County.
If you haven't done so already you should follow these tips. We're in store for a very long cold spell:
1. Disconnect all outside hoses from your faucets
2. Cover up foundation vents
3. If your bathroom has plumbing along an outside wall leave the cabinets doors open to ensure some heat reaches the pipes.
4. Keep vulnerable faucets dribbling to keep them from freezing. (especially if you have a well)
5. Make sure you car has antifreeze style windshield fluid. (many brands sold here offer minimal freeze protection)
6. Be careful of any auxiliary heat sources. (many could have a fire or carbon monoxide risk). Make sure detectors work.
7. Check in on elderly neighbors.
8. Be patient when it comes to any traveling. If you can't drive in the snow or if you vehicle isn't properly equiped then stay home or take the bus.
9. Throw out some seed or bread scraps for the birds.
10. Make sure your pets are properly cared for.
11. And remember that most cold spells here in the PNW ultimately get driven out by rain. And when a new rain storm meets frigid ground temps it usually results in freezing rain. Plan accordingly!! (fuel up and test that generator and make sure you have emergency food and water to last several days)
12. Joe the Plumber might be pretty busy this week!! Have some emergency plumbing supplies on hand to tide you over just in case.
Have a hot toddy and enjoy!!
