The WSWC has long supported efforts to improve seasonal and mid-season forecasting, federal agency data-collection, and application development for more informed water resource management. Here is a collection of reports, workshops, and other materials related to the topic, gathered and distributed by WSWC.

July 2016 Congressional Staff Briefing on S2S Precipitation Forecasting

Atmospheric River-driven storms can make or break a water year in the West. An interagency, cross·disciplinary team of experts is exploring the viability of utilizing forecasts of atmospheric rivers and their heavy precipitation in operational decisions at key western reservoirs that have been plagued by drought.  Such forecasts could provide sufficient notice of these events to enable prudent planning and adaptable operation so that water managers would be better positioned to maximize water supply while maintaining public safety.  Additionally, water decisions across the West can benefit from longer lead time information on precipitation from weeks to seasons in advance.

A briefing designed for Congressional staff about atmospheric rivers, subseasonal·to·seasonal precipitation prediction needs, related weather forecasting technology, and their potential benefits to the future of water management was held July 13, 2016.
