Resolution Criteria

This market resolves YES if the National Weather Service Seattle/Tacoma office issues a storm warning, watch, or advisory for the Seattle area on or before 2/28/2026 11:59 PST. (Or tornado, blizzard, or any other critical weather event.) This includes winter storm warnings, severe thunderstorm warnings, wind advisories, or other official storm-related alerts. Resolution will be verified via the National Weather Service Seattle/Tacoma office at https://www.weather.gov/sew. If no such alert is issued by the deadline, the market resolves NO.

Background

Most storms in Seattle happen in late fall and winter, with seven of ten major storms since 1962 occurring in winter. The Puget Sound region experiences strong windstorms, including ones with hurricane force winds known as mid-latitude cyclones. Pineapple Express storms also pack strong winds and are known more for their rain than wind, occurring when the jet stream dips into tropical regions; they can include flooding, landslides, and power outages.

Considerations

"Storm" is defined broadly to include any National Weather Service alert for hazardous weather conditions, not limited to severe wind events. This captures winter storms, severe thunderstorms, and other significant weather phenomena that the NWS deems worthy of official warning or advisory status.
