Note: The hydrograph at the top of the page is the official NWS forecast for this location based on 48 hours of forecasted rainfall. The ensemble hydrographs shown here are used to assess the range of possible river levels and likelihood of river flooding over the next 10 days using dozens of model-derived, 10-day rainfall forecasts.

See the Product Description Document link for more information on the Meteorological Model-based Ensemble Forecasting System (MMEFS) which produces the ensemble hydrographs above.

Clicking on each ensemble hydrograph enlarges the graph and takes you to the MMEFS website for additional guidance.
