The Atmospheric River (AR) Portal was developed in order to provide a home for atmospheric river-related forecasts and diagnostics. The AR Portal was developed as a cooperative effort between the Plymouth State Meteorology Program, the University of California-San Diego Scripps Center for Western Weather and Water Extremes (CW3E), and the NOAA Earth Systems Research Laboratory. The information contained on the AR Portal 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.
Current AR Landfall Probability Tool is below. Go to the AR Portal for more information.
