Traders overwhelmingly back 5-6 inches of Seattle precipitation in March at 42.7% implied probability, driven by NOAA's Climate Prediction Center outlook signaling above-normal rainfall across the Pacific Northwest due to emerging La Niña conditions, which historically amplify winter-spring wetness in the region. Seattle's March climatological average hovers around 3 inches at Sea-Tac Airport, but recent NWS observations show early-month accumulations already exceeding 1.5 inches amid persistent atmospheric rivers, boosting odds for 6-7 inches (19.4%) and higher bins. Ensemble models from ECMWF and GFS reinforce this with 60-70% chances of wetter-than-normal totals, though late-month drying risks could cap extremes above 8 inches (15%).

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.
