Trader consensus on Polymarket heavily favors 5-6 inches of precipitation in Seattle for March at 87.9% implied probability, driven by the latest NOAA Climate Prediction Center seasonal outlook showing above-normal rainfall probabilities across the Pacific Northwest due to a persistent upper-level trough and favorable jet stream positioning for repeated Pacific storm systems. Recent atmospheric river events in late February delivered record February totals exceeding 8 inches at SeaTac, building momentum into March with current GFS and ECMWF model ensembles projecting additional 2-3 inches in the first half of the month amid neutral ENSO conditions. Historically, March averages 3.1 inches, but wet analogs like 2023's 6.9-inch total align with this positioning; uncertainty persists from potential ridging, with weekly NOAA forecast updates expected to refine totals ahead of month-end resolution.

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.
