Outages climb in Whatcom County as crews track the damage
Puget Sound Energy’s latest tally at 9: 00 PM ET puts the number of customer addresses without power at 11, 423 across Whatcom County. The utility’s report describes the impact as widespread across the county, while its outage tracking map reflects multiple interruptions rather than a single isolated failure.
The immediate driver is wind: the advisory from the National Weather Service Seattle office signaled a high-risk evening for falling branches and storm-driven disruptions to overhead lines. While restoration timing was not provided in the available update, the scale of the outage count indicates a major operational response for the utility as conditions remain active.
Power Outage Seattle winds: advisory calls for 20–30 mph with gusts up to 50 mph
The National Weather Service Seattle office forecast southwest winds of 20 to 30 mph with gusts up to 50 mph for the evening. Forecasters also warned that winds in areas from Everett north were expected to shift to northwesterlies at 20 to 30 mph, again with gusts up to 50 mph, during the window of 8: 00 PM to 11: 00 PM ET on Wednesday.
That shift matters because changing wind direction can bring new stress to trees and power infrastructure already being pushed by earlier gusts. In practice, that can mean additional interruptions even after initial outages are logged, especially during the strongest part of the advisory window.
Immediate reactions from institutions on the ground
