Station Move
Added 9/5/14

The DEOS station at Viola (DVIO) has moved to a new site due to siting problems that were adversely affecting the quality of the station's data. As a result, the station has been renamed to Woodside, DE-Willow Grove (DWDS). From a climate standpoint, this station is considered a new station, as it exceeds the distance required to remain a climatologically consistent station. However, the station still serves the same general area in Delaware and will once again serve as a snow monitoring site in the upcoming 2014-2015 snow season. Data from Viola will remain in DEOS and are available upon request.
