Locally Extreme Precipitation Forecasts


Welcome to the webpage for extreme precipitation forecasting with machine learning. This page contains real time CONUS-wide probabilistic forecasts for 1-year and 10-year return period exceedances. Currently, forecasts are broken into eight distinct regions, and forecasts are based solely on GEFS/R fields. Furthermore, only day two (F36-60) forecasts are available at this time, and only for 24-hour precipitation accumulations. More lead times and accumulation intervals will become available in the future. Complete methodology for these forecasts will be described in a forhcoming publication(s). Methodology is currently under development and subject to change.

DISCLAIMER:These forecasts are provided for informational purposes only; the creator assumes no responsibility for the forecasts or actions of others derived therefrom. This disclaimer applies to all forecasts provided on this page or any other forecast product presented elsewhere on this website.
