Buffalo, NY – Twenty years ago today, Western New York experienced one of its most destructive early season snowstorms, leaving hundreds of thousands without electricity, shutting down major highways and causing widespread damage across the Buffalo region.
According to the National Weather Service in Buffalo, the historic October Surprise Storm struck Oct. 12 13, 2006, dumping 22.6 inches of snow at Buffalo Niagara International Airport.
The snowfall remains the highest 24 hour October accumulation recorded at the airport, according to the agency.
Unlike typical winter storms, this event struck while many trees still carried their autumn leaves. Heavy, wet snow accumulated on branches, causing widespread tree damage and bringing down power lines throughout Erie County and surrounding communities.
The consequences were devastating.
Approximately 400,000 customers lost electricity, with some residents waiting up to two weeks for service to be restored.
The storm caused more than $150 million in damage, generated over 3 million cubic yards of debris and damaged an estimated 90% of trees in affected areas.
Transportation across Western New York also came to a standstill. A 105 mile stretch of the New York State Thruway, Interstate 90, was closed, while hazardous conditions disrupted travel throughout the region.
The National Weather Service reported four deaths associated with the storm, while more than 200 people experienced carbon monoxide poisoning during the emergency.
More than 1 million people were affected overall.
On Monday, Oct. 12, 2026, the National Weather Service is marking the storm's 20th anniversary by sharing historical photographs, snowfall maps and information documenting the disaster.
The anniversary serves as a reminder of how quickly an early season weather event can become dangerous, particularly when heavy snow combines with trees that have not yet shed their leaves.
For longtime Western New York residents, the October Surprise Storm remains an unforgettable chapter in the region's weather history.
