NWS WPC produces Quantitative Precipitation Forecasts (QPFs) that depict the amount of liquid precipitation expected to fall in a defined period of time. In the case of snow or ice, QPF represents the amount of liquid that will be measured when the precipitation is melted.

Provided by the University of Colorado Boulder and NASA's Jet Propulsion Laboratory, these reports provide near-real-time estimates of snow-water equivalent (SWE) at a spatial resolution of 500 m for the Sierra Nevada mountain range in California and the Intermountain West region (Colorado, Utah, and Wyoming) from mid-winter through the melt season. 

The Bureau of Reclamation's interactive Reservoir Storage Dashboard provides current conditions for 44 major Reclamation reservoirs and comparisons with historical storage data. For each reservoir, users can view the current storage amount in acre-feet, the current storage level as a percent of average (based on the last 30 years of data), and records for lowest observed storage.

NOAA and its partners publish regional reports each quarter, summarizing weather, impacts and predictions.
