A power outage struck a large section of Bellingham on Wednesday afternoon, September 2, knocking out electricity to more than 2,700 homes and businesses and leaving residents without power for several hours during a period of already unsettled weather across Whatcom County.
Puget Sound Energy reported the outage began at approximately 5 p.m. According to PSE's outage map, 2,737 customers were affected. As of about 5:05 p.m., the utility's estimated restoration time was 8 p.m. that evening, a roughly three-hour window without electricity for thousands of customers. The scale of the outage placed it among the larger single-event disruptions the Bellingham service area has seen in recent months, affecting a footprint large enough to span multiple neighborhoods and commercial corridors.
The outage came on a day when a wind advisory was in effect for the lowlands of western Whatcom County, with south winds of 15 to 25 mph and gusts up to 45 mph forecast by the National Weather Service. Full foliage on trees in early September increases wind resistance compared to winter conditions, making downed limbs and lines more likely during gusty weather even at wind speeds that would cause fewer problems when trees are bare. That foliage factor is something utility crews contend with every late summer and early fall, and it is one reason that September outages can be disproportionately impactful relative to the actual wind speeds involved.
A Recurring Problem in This Area
What makes Wednesday's outage particularly notable is that it was not an isolated event. According to Whatcom News, this was the third power outage affecting the same area of Bellingham since June 5. In the two prior incidents, the cause was identified as a bird or animal interfering with electrical infrastructure, a category of outage that utility workers refer to as "animal contact" or "wildlife contact."
Wildlife-caused outages are more common than many residents realize. Squirrels, birds, and other animals that come into contact with transformers, conductors, or other energized equipment can cause faults that trip protective devices and cut power to large sections of a distribution circuit. The mechanism is straightforward: an animal large enough to bridge the gap between an energized conductor and a grounded surface creates a path for current to flow, which trips the circuit breaker or fuse protecting that section of line. The animal is typically killed instantly, and the fault clears, but the protective device has already operated and must be reset or replaced before power can be restored.
Puget Sound Energy, which serves most of Bellingham and the surrounding area, has programs in place to install wildlife guards on the most vulnerable equipment, but the scale of the distribution network means that not every piece of exposed hardware has been treated. Transformers, cutout switches, and bare conductor connections at pole tops are among the most common sites for animal contact events, and retrofitting all of them across a large service territory takes years and significant capital investment.
Three outages in the same area within roughly three months suggests either that the underlying infrastructure vulnerability has not been fully addressed or that new animal activity is exposing previously protected equipment. It is also possible that a particular pole or substation component has been identified as the cause of earlier outages but has not yet received a permanent repair. Residents and neighborhood associations can report recurring outage locations to PSE to flag them for additional wildlife protection measures, and customers who have experienced multiple outages at their address have standing to request a formal service review from the utility.
The pattern also raises questions about how PSE tracks repeat-fault locations and escalates them for preventive maintenance. Most large utilities use outage management systems that log the location and cause of each interruption, allowing engineers to identify chronic problem sites. Three events in three months at the same location would typically trigger a review under standard utility reliability practices, and it is worth asking whether that review has occurred and what, if any, corrective action has been scheduled.
The Broader Weather Context on September 2
Wednesday's weather was unusually active for early September in Whatcom County. Beyond the wind advisory for the lowlands, a gale warning was in effect for the Northern Inland Waters from early morning through 11 p.m., with southeast winds of 25 to 35 knots and wave heights of 3 to 4 feet on the Strait of Juan de Fuca and San Juan Islands waters. Mariners and ferry operators were contending with conditions that made small-craft travel genuinely hazardous, and the combination of high winds on both land and water compressed the options available to people who needed to move around the region.
The National Weather Service Seattle office described the pattern as driven by an anomalously strong low-pressure system moving through the region, bringing a cold front and the possibility of thunderstorms with lightning and small hail. That combination, wind, rain, and potential lightning, creates elevated risk for additional infrastructure disruptions beyond the standard wind-related outages. Lightning strikes on distribution lines can cause the same kind of protective device operation that animal contact does, and the two causes are sometimes difficult to distinguish after the fact without detailed equipment inspection.
Whatcom County Emergency Management maintained its Stage 2 burn ban through this period, with fire danger remaining at Very High levels despite the incoming rain, as wet conditions at lower elevations do not immediately translate to reduced fire risk in the Cascades where fuels had been drying out through a drought that began in April. The simultaneous presence of a wind event, a fire risk advisory, and a large power outage illustrates how compound hazard situations can develop quickly in Whatcom County, particularly in the transition from summer to fall when weather patterns become more dynamic.
What to Do During an Outage
For Bellingham residents, the pattern of three outages in the same area over a few months is a useful prompt to review home preparedness for extended power loss. A three-hour outage is an inconvenience for most households, but the same infrastructure that produced three shorter outages is also capable of producing a longer one under the right conditions, particularly if a more severe weather event causes more extensive damage that takes longer to assess and repair.
The Whatcom County Emergency Management Division recommends that households maintain at least 72 hours of supplies, including water, food that does not require refrigeration, flashlights, and battery or hand-crank radios. Residents who rely on electrically powered medical equipment should have a specific plan for extended outages, including contact information for their utility and their medical provider. Residents can sign up for emergency alerts through WhatcomReady.
During an outage, PSE customers can report their address as affected through the PSE website or by calling the utility's outage line, which helps the company prioritize repairs and improves the accuracy of restoration time estimates. That reporting matters because PSE's outage management system uses the volume and location of customer calls to estimate the scope of a fault and dispatch crews accordingly. Customers who do not report their outage may not be accounted for in the crew deployment plan, which can extend restoration times for isolated pockets of affected customers near the edge of an outage zone.
For the latest Whatcom County weather and emergency management information, the Wednesday briefing from Whatcom County Emergency Management provided a detailed picture of conditions across the county that day and is worth reviewing alongside this outage report for full context on what residents were dealing with on September 2. The convergence of wind, a gale warning, a burn ban, and a major power outage in a single afternoon serves as a reminder that Whatcom County's geography and climate create conditions where multiple hazards can materialize at the same time, and that basic preparedness remains relevant even in the relatively mild shoulder season between summer and fall.
