Power Outage Seattle windstorm outages highlight a widening regional reliability test

Power outage seattle attention is sharpening as wind-driven outages spread beyond the city’s core, with Puget Sound Energy reporting 11, 423 customer addresses without power across Whatcom County as of 9: 00 p. m. ET on Wednesday, March 11, 2026. The same evening, National Weather Service Seattle office forecasters issued a wind advisory that points to a clear near-term trajectory: outage totals may track closely with the timing, direction shifts, and peak gusts expected overnight.

Puget Sound Energy totals put Whatcom County at 11, 423 without power

The clearest confirmed datapoint in the current storm snapshot is the utility count: as of 9: 00 p. m. ET on March 11, 2026, Puget Sound Energy listed 11, 423 customer addresses without power across Whatcom County. The context does not specify which neighborhoods or circuits are most affected, or how quickly crews are restoring service. Still, the scale of the count establishes the immediate baseline for how the event is unfolding north of Everett, and it helps frame the broader regional concern reflected in the day’s headlines about strong winds knocking out power for thousands in Washington.

That baseline also creates a measurable reference for what comes next: any further updates, if provided later, would be interpretable against the 9: 00 p. m. ET figure. For now, the number itself is the primary signal of present impact, and it is explicitly tied to a named utility and a defined geography: Whatcom County.

National Weather Service Seattle advisory signals peak risk between 8: 00 p. m. and 11: 00 p. m. ET

The main driver visible in the context is the wind forecast described by National Weather Service Seattle office forecasters. The advisory calls for southwest winds of 20 to 30 mph with gusts up to 50 mph expected for the evening. It also specifies a directional shift: winds in areas from Everett north are expected to switch to northwesterlies at 20 to 30 mph, also with gusts up to 50 mph, between 8: 00 p. m. and 11: 00 p. m. ET on Wednesday.

Two operationally relevant signals come through in that phrasing. First, the forecast emphasizes gust potential up to 50 mph, which aligns with the type of short, higher-force bursts that can coincide with outage spikes. Second, the expected switch in wind direction from Everett north creates an explicit timing window for heightened disruption risk in the same broader corridor that includes Whatcom County. In trend terms, the forecast is not just describing wind strength; it is describing a changeover period that could correspond to a second wave of impacts even after initial southwest winds arrive.

Power Outage Seattle focus shifts toward gust timing and direction changes

The region’s outage story is increasingly being shaped by two measurable elements contained in the current advisory: gust ceilings and the 8: 00 p. m. to 11: 00 p. m. ET wind shift north of Everett. That creates a trajectory where the evening’s outage footprint could evolve in step with the forecast window rather than remaining static after the first reports. In practical terms, the confirmed 11, 423-out figure at 9: 00 p. m. ET sits inside the same high-risk window described by the advisory, which makes subsequent changes in totals a key signal of whether conditions are intensifying or stabilizing.

If the current trajectory continues… and gusts reach the stated up-to-50-mph levels through the 8: 00 p. m. to 11: 00 p. m. ET period in areas from Everett north, the outage picture could remain fluid, with the possibility of additional customer addresses losing power beyond the 9: 00 p. m. ET count. The context supports this scenario only as a conditional: it links the strongest wind period to the same corridor where the confirmed outages are already significant.

Should the wind-direction switch occur as described… from Everett north between 8: 00 p. m. and 11: 00 p. m. ET, the pattern of impacts could shift geographically within the affected corridor, even if the peak gust figure remains the same. The advisory specifically distinguishes southwest winds from northwesterlies, implying that exposure may change as wind angles change. The context does not identify specific infrastructure vulnerabilities, so the scenario remains limited to what is stated: a time-bounded directional shift that can coincide with changes in outage distribution.

For now, the next concrete milestone embedded in the context is the end of the advisory’s most detailed timing window: 11: 00 p. m. ET on Wednesday, when the forecast highlights the period for the wind switch from Everett north. What the context does not resolve is whether Puget Sound Energy’s outage totals rise or fall after 9: 00 p. m. ET, or how restoration progress compares across different parts of Whatcom County, leaving the near-term outlook dependent on subsequent utility updates and whether gusts reach the upper end of the forecast.
