The National Weather Service featured our new operational 3-month precipitation forecast in their monthly publication  Coast to Cactus Weather Examiner. The featured seasonal precipitation model, which was developed by Tamara Shulgina and Alexander Gershunov, is part of the Subseasonal to Seasonal (S2S) forecasting effort  at the Center for Western Weather and Water Extremes (CW3E).  The product uses information from tropical and north Pacific sea surface temperature anomalies to predict precipitation over the western U.S. at lead times of 1-3 months for use in water management decisions.  More information can be found by clicking here.
