Background

The Old Farmer's Almanac and NOAA have released their winter forecasts for 2024-2025. For the Pacific Northwest, predictions indicate above-average precipitation and snowfall in the northern regions, with the snowiest periods expected in late December, early January, and early February. The forecast is influenced by expected La Niña conditions, which typically bring wetter and cooler weather to the Pacific Northwest.

Resolution Criteria

This market will resolve YES if either Seattle or Tacoma records above-average snowfall for the 2024-2025 winter season (measured from first snowfall through the end of winter on March 19, 2025). Snowfall measurements will be based on official National Weather Service data from Seattle-Tacoma International Airport. The historical average will be determined using the 30-year average snowfall data for the region.

Considerations

• Seattle averages about 5 inches of snow annually, while Tacoma typically receives slightly more due to its location and elevation

• Microclimates within the Seattle-Tacoma area can result in varying snowfall amounts, but only official NWS measurements will be used for resolution

• La Niña conditions can significantly impact winter weather patterns in the Pacific Northwest, though local variations can still occur
