General Meeting Information

The Climate Impacts Group's (CIG's) fall forecast meeting provides an opportunity to hear how forecasted climate conditions for winter 2009-2010 may affect regional climate and streamflow conditions in the Columbia River Basin and western Washington and Oregon in summer 2010. The meeting also provides a forum for sharing the latest research on climate impacts and climate forecasting in the Pacific Northwest (PNW).

Meeting participants

This year's CIG's fall forecast meeting drew representatives from a variety of agencies, including, but not limited to, the following:
