Proposed Change to NWS Grand Junction Radar - Public Input

The National Weather Service is proposing to lower the elevation scan of the WSR-88D 
Doppler Radar in Grand Junction, CO. This will allow for better scanning of the atmosphere 
from a radar that is located over 10,000 feet in elevation. These improvements will provide 
better radar coverage for much of eastern Utah and western Colorado.

A Draft Environmental Assessment (EA) for lowering the minimum scan angle of the 
Weather Surveillance Radar-Model 1988 Doppler (WSR-88D) serving the Grand Junction, 
CO, area is now available for public comment. The Draft EA document can be obtained at:

DRAFT Environmental Assessment

The NWS will accept written comments on the Draft EA until September 18, 2019. We appreciate your interest in this important project.
