Update: 4:30 p.m., Friday West Seattle bus routes 54 and 55 are operating their regular routes.

Line 51 is currently operating the western portion of its routing: Alaska Junction - Genesee Hill - Admiral Junction - Alaska Junction.

Route 128 does not enter the South Seattle Community College campus. It operates on 35th Avenue Southwest and Southwest Alaska Street to and from the Alaska Junction instead of Southwest Morgan Street and California.

Update: 2:40 p.m., Friday High winds forecast this weekend may lead to power outages in some parts of the city.

"We can't predict which neighborhoods if any may lose power, so we want to encourage all residents of King County to have a plan about how to stay warm and safe during adverse weather," said Dr. David Fleming, director and health officer for Public Health, Seattle and King County. "If possible today, stock up on supplies you may need during the weekend and think about how you will stay warm and safe during a possible outage."

Given the cold temperatures, Public Health advises all residents to take steps to stay safe and warm and especially to avoid carbon monoxide poisoning.

"City crews have been working around the clock making great progress on our main roads, but drivers still need to be extremely cautious getting around town,? said Mayor Greg Nickels in a statement just released. ?We ask drivers to be patient and use their best judgment especially on Seattle?s steep hills.?

As temperatures are expected to drop significantly later today, roadway surfaces may refreeze. The city will continue to monitor pavement conditions closely and will again put priority on primary arterials, especially the West Seattle Bridge and the Alaskan Way Viaduct, if conditions worsen.

Crews operating 20 plow and sanding trucks remain on 12-hour shifts and will continue working through the night. An additional 40 personnel worked through the day to clear sidewalks and stairways near critical pedestrian locations, such as hospitals and food banks. While the strongest winds are expected to hit the Cascades and foothills, the Seattle area could see sustained winds of 20 to 30 mph, according to the National Weather Service.

Public golf courses, West Seattle, Jefferson Park, Interbay and Jackson Park, are closed.

If power goes out, the County recommends the following:

Keep the doors closed on your refrigerators and freezers as much as possible. This keeps the cold air inside. A full freezer can stay at freezing temperatures about two days; a half-full freezer about 1 day.

If you think the power will be out for several days, try to find some ice to pack inside your refrigerator. Remember to keep your raw foods separate from your ready-to-eat foods.

Refrigerated foods should be safe as long as the power is out no more than a few hours and the refrigerator/freezer doors have been kept closed. Potentially hazardous foods, such as meat and fish, should be discarded if they warm up above 41
