Seattle is under a High Wind Warning for Wednesday, December 24. The National Weather Service issued a High Wind Watch for Western Washington on the morning of Tuesday, December 23. Then the alert was upgraded to a High Wind Warning in the early hours of Wednesday morning, which means a more severe and probable forecast. It will be in effect from the morning through 7:00 p.m. on Wednesday evening, so Seattle residents should be prepared for a blustery Christmas Eve. Strong winds and waterlogged soil could lead to travel delays and power outages.
Read on for all the important info.
Winds will start out from the east to northeast, with gusts up to 35 mph. By Wednesday afternoon, conditions will change quickly as winds shift to the south and strengthen significantly. Sustained speeds of 25–35 mph are expected, with powerful gusts that could reach 50–60 mph.
These strong winds may cause trees and power lines to come down, leading to the possibility of widespread power outages. Travel could also be challenging, especially for drivers of high-profile vehicles like trucks, vans, and buses.
If the storm develops as expected, already saturated ground across the region could increase the risk of power outages. After two weeks of repeated atmospheric rivers and record-setting flooding, soils are still waterlogged, and many trees were left vulnerable following the windstorm on December 17.
How to prepare
Secure or bring inside any loose outdoor items such as holiday decorations, patio furniture, and garbage bins. Stay alert by monitoring the latest forecasts and warnings, and be ready for changing conditions throughout the day. Having a battery-powered radio on hand is a reliable way to get updates if your power goes out. And of course, be sure to charge your devices ahead of time and stock up on fresh batteries for your flashlights.
Additional advisories from NWS after the upgrade from watch to warning: “People should avoid being outside in forested areas and around trees and branches. If possible, remain in the lower levels of your home during the windstorm, and avoid windows. Use caution if you must drive.”
Taking a few precautions now can help you stay safe during Seattle’s windy Christmas Eve.
