These seasons create the foundation upon which Portland's notable weather events have occurred.
Noteworthy Storms in Portland's History
Portland has faced several storms that have left lasting marks on its history. Below are some of the most significant ones:
The Columbus Day Storm of 1962
The Columbus Day Storm, also known as the "Big Blow," struck Portland on October 12, 1962. This extratropical cyclone is widely regarded as one of the most powerful windstorms to hit the western United States. With winds reaching up to 116 miles per hour, the storm caused widespread devastation. Thousands of trees were uprooted, homes were damaged, and power outages affected millions. The storm's magnitude and the destruction it left in its wake make it an unforgettable part of Portland's weather history.
The Flood of 1996
Another significant event was the Portland Flood of 1996. Persistent rainfall, melting snow from the Cascade Range, and overflowing rivers combined to cause catastrophic flooding. The Willamette River, which flows through the heart of Portland, reached dangerously high levels, inundating neighborhoods and causing significant damage to infrastructure. This flood remains a stark reminder of Portland's vulnerability to extreme weather conditions.
The Snowstorm of 2008
Portland weather history also includes remarkable snowstorms, notably the one in 2008. Although not accustomed to significant snowfall, Portland was blanketed by nearly 20 inches over December. The city, often unprepared for such precipitation, faced transportation challenges, school closures, and business disruptions. This snowstorm emphasized the importance of preparedness in facing uncommon weather phenomena.
