The Pacific Northwest Climate Impacts Research Consortium (CIRC), formerly the Pacific Northwest Climate Decision Support Consortium (CDSC), provides information and tools to support decision making about landscape and watershed management in the region in a changing climate. It is a member of NOAA's Regional Integrated Sciences and Assessments (RISA) program, which supports climate research for decision-makers and policy planners at a regional level, representing Washington, Oregon and Idaho.
This website from the U.S. Fish and Wildlife Service provides a synthesis of climate science in the Pacific Region, including separate pages for the Pacific Northwest and for the Pacific Islands.

The Climate Impacts Group (CIG) provides these maps to show how four important parameters of climate - temperature, precipitation, snowpack, and soil moisture - vary over time in the Pacific Northwest (PNW) as a result of natural climate variability and climate change. These maps show climate anomalies associated with different patterns of climate variability compared to average conditions during 1915-2003. The data are derived from historical climate measurements, global climate model simulations, and a spatially-distributed hydrology model.

The Snow Survey and Water Supply Forecasting program provides western states and Alaska with information on future water supplies (January - June for the current year). USDA Natural Resources Conservation Service field staff collect and analyze data on depth and water equivalent of the snowpack at more than 1,200 mountain sites and estimate annual water availability, spring runoff, and summer streamflows. Individuals, organizations, and state and federal agencies use these forecasts for decisions relating to agricultural production, fish and wildlife management, municipal and industrial water supply, urban development, flood control, recreation power generation, and water quality management.
