The National Weather Service’s Daily Climatological Report provides the deciding data. Resolution uses the Miami entry in the “Precipitation (IN)” table, specifically the “Month to Date” row and “Observed Value” column, as published on the day immediately following the last day of October 2026; the value becomes final on November 1, 2026, and subsequent revisions or recalculations do not affect resolution. An outcome is Yes if that value exceeds the threshold specified in the market question, and No otherwise.
