Seattle's most underrated weather risk isn't earthquakes — it's high winds, toppling large trees, and the prolonged blackouts that follow. The Hanukkah Eve Windstorm of 2006 struck the greater Seattle area with winds of ~90 mph, knocking out power to ~1.5 million homes, leaving some areas without electricity for up to 10 days, and claiming 15 lives — most from improper heating-related carbon monoxide poisoning. That disaster left local homeowners with concrete, lasting lessons.
The 2006 Storm
On the night of December 14, 2006, a powerful windstorm hit the Seattle area with winds reaching ~90 mph. Countless large trees were uprooted, crushing homes, vehicles, and power infrastructure. About 1.5 million homes lost power; some areas went 10 full days without electricity. Combined with post-storm snow and freezing temperatures, the 10-day blackout became one of the worst winter storm disasters in Seattle history — Wikipedia dedicated a full article to the event.
The Real Weather Risk: Wind and Trees
Many think Seattle's biggest weather risk is earthquakes, but the higher-frequency, more realistic daily threat is high winds and toppling trees. Seattle has abundant large trees in moist soil; in strong winds, towering trees can be uprooted, crushing homes and downing power lines. Storms of similar intensity have occurred in recent years, again leaving families dealing with blackouts, cold, and fallen trees. For homeowners, this means nearby tree condition must be part of property risk assessment — not just the home itself.
The Cost of Blackouts
Fallen trees downing lines means prolonged blackouts. In wet, cold winters, losing heat, hot water, and lighting is especially dangerous for the elderly and children. In 2006, because gas stations need electricity to pump fuel, many families were stranded at home without power, heat, or gas — cold and hungry — underscoring the importance of emergency preparedness.
The Deadly CO Lesson
15 died in the 2006 storm, most from carbon monoxide poisoning due to improper heating or power generation. This lesson must be internalized: generators must be placed outdoors, at least ~20 feet from doors and windows — never in a garage, basement, or other enclosed space, even with doors open. Homes should have battery-operated CO detectors with regularly checked batteries — detectors powered by wired electricity will fail during outages. Never use charcoal, grills, or propane for indoor heating. Kerosene heaters may only be used indoors when the packaging specifies indoor-use certification. Before using a fireplace, always open the damper to prevent smoke and CO from backdrafting.
Homework for Homeowners
Local homeowners should complete three routine tasks. First, assess nearby tree risk: check for tall, aging, or root-unstable trees near the house — trim or remove as needed. Second, prepare for blackouts: backup power, safe heating alternatives, adequate drinking water and food. Third, check wind and drainage resilience: can the roof, windows, and drainage system withstand a storm?
What to Check When Buying
Don't only view a home on a sunny day. Buyers should proactively ask about historical storm and blackout conditions in the area and assess potential risks from nearby trees and terrain. A property surrounded by large trees, in a low-lying area, or on a fragile grid carries hidden living costs and risks that won't appear in the listing price — but will fully surface during extreme weather. Factoring these in is essential to finding a home that truly provides peace of mind.
Summary
The 2006 disaster reminds Seattle homeowners: the local weather risk priority isn't earthquakes — it's wind and trees. For local Chinese-American homeowners and buyers: treat tree management, blackout preparedness, and wind-resilience maintenance as routine homework; keep battery-operated CO detectors and know how to safely use a generator. During the buying phase, include nearby trees, topography, and grid reliability in your due diligence. Being prepared is how you protect your family's safety and your property's value when the next storm comes.
