On Sunday, Hiawatha Community Center will be  open from noon – 5:00 pm for shelter should you need it.  From the Press Release:

“Seattle Public Utilities reminds residents to prepare water pipes for cold weather. Shut off outside faucets, drain the water and protect them by insulating them with rags or foam covers. Pipes in exposed or unheated areas (attics, basements and garages) should be wrapped with tape and insulating materials, available at local hardware stores. Drain and remove all outdoor hoses, and shut off and drain in-ground sprinkler systems.

Residents are also urged to protect indoor sink pipes that are against exterior walls, by opening under-sink cabinet doors, allowing heat to circulate. During severe cold, allow the faucet farthest from your front door to slowly drip cold water. Set your thermostat no lower than 55 degrees Fahrenheit, day or night (even if you are away).

If a water pipe breaks, immediately close the main shut-off valve to stop excessive flooding. If you cannot turn off the main shut-off valve, SPU customers can call  (206) 386-1800  and a crew will turn off the water at the meter for a standard service charge.”
