NWPS Forecast Verification Page
Open Water Year 2025
This page provides statistical metrics for deterministic forecasts issued by the APRFC. The evaluation compares
operational stage forecasts against USGS observations across all 6-hour issuance times over a 72-hour lead time.
Please note that APRFC forecasts are seasonally dependent and are primarily issued during the open water season
from May through October.
Each plot summarizes the performance of a specific forecast point. You can use the first dropdown menu to select
a forecast evaluation point from water year 2025, and the second menu to view a forecast rank analysis.
