A Finding of No Significant Impact (FONSI) has been signed to improve meteorological monitoring in alpine environments in North Cascades National Park Service Complex. Improvements to the existing meteorological monitoring network in cooperation with Seattle City Light, Puget Sound Energy and the Natural Resource Conservation Service will provide better information on weather, climate and precipitation patterns.

The FONSI records the decision of the National Park Service to install four new remote, high-elevation monitoring sites this fall to support the park’s long term ecological monitoring program as described in Alternative B of the Environmental Assessment. These sites will provide hourly data to resource managers and the public via the web to improve understanding of watershed processes and glacier dynamics in response to global climate change.

The Finding of No Significant Impact document can be viewed on-line at the National Park Service Planning, Environment, and Public Comment (PEPC) website. Select "Improve Meteorological Monitoring in Alpine Environments," then "Document List," and "Finding of No Significant Impact."
