Trader sentiment favors 5-6 inches of Seattle precipitation in March at 42% implied probability, closely trailed by 6-7 inches at 31.6%, as seasonal forecasts from NOAA and ECMWF signal above-normal rainfall amid a transition to weak La Niña conditions that historically amplify Pacific Northwest storm tracks and atmospheric rivers. Seattle's March climatological average hovers around 3 inches at Sea-Tac Airport, but recent wet winters—2023's 5.2 inches and early 2025's saturated February—bolster expectations for the higher bins, with GFS ensemble models projecting 120-150% of normal totals. Traders eye upcoming NOAA Climate Prediction Center updates by mid-February for resolution criteria tied to official monthly totals.

The resolution source for this market will be NOAA, specifically the figure for March 2026 when the "Monthly summarized data" for "Seattle City Area" is selected with the variable set to "Precipitation" at the https://www.weather.gov/wrh/climate?wfo=sew link once that figure is finalized for the whole month of March 2026.
If the reported data falls exactly between two brackets, this market will resolve to the higher bracket.
The resolution source for this market measures precipitation to 2 decimal places (e.g., 1.54), thus, this is the level of precision that will be used when resolving this market. Any revisions to precipitation recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
