Research
		Current Priorities: Skagit Watershed/Seattle City Light Project (weather, streamflow, and snowpack forecasting capability for Seattle City Light). Expansion of hydrologic prediction capability throughout Washington, Oregon, and southern British Columbia. Integration of WSR-88D radar derived rainfall estimates into forecast process (Seattle and Portland urban regions) Operational assimilation of MODIS satellite imagery for updating of model predicted snowpack extent. Medium and long-range steamflow forecast capability using a combination of deterministic and statistical prediction methods.
