Introduction: The purpose of this website is to provide a portal for atmospheric river forecasts and diagnostics from the NCEP GFS Ensemble Forecasts. This website has been developed as a cooperative effort between the Plymouth State University meteorology program and the University of California-San Diego Scripps Center for Western Weather and Water Extremes (CW3E). The information contained on this website serves as a starting point for analyzing the current and forecasted meteorological conditions associated with atmospheric rivers and ultimately as a starting point for decision making efforts concerning water resource management related to atmospheric rivers and the extreme precipitation that they may cause in the one-to-two week time frame.

For any questions or comments on the AR Portal and the NCEP GFS forecasts herein, please contact Dr. Jason Cordeira at Plymouth State University at j-underscore-cordeira-at-plymouth-dot-edu.
