Automated Snow Pillow Commentary
UPDATED: May 3, 2016
A bi-weekly commentary of snow conditions based on readings from the BC Automated Snow Pillow (ASP) network is published during the snow season.
Since mid-April, a couple of spells of hot weather together with the warmer than normal spring temperatures has resulted in notable decreases in snowpack conditions across the province. The provincial average snow water equivalent (SWE) as measured by the ASP network, referenced to long-term average conditions for this period, has decreased from 83% on April 15th to 63% as of May 1st.
As is common for this time of year, snow pack measurements show a substantial degree of variability throughout the province with some ASPs recording no snow and others retaining normal values for early May (see links below for data and pillow map). Most of the ASPs in the north, Upper Fraser basin, coastal regions and the far south-east are well below normal. Average or above average conditions are evident in the upper elevations of the Okanagan, Kettle, and Thompson basins.
The detailed listing of all snow pillows can be downloaded here: ASP Weekly Summary and a summary map of snow pillow data can be viewed here: ASP Weekly Map.
The next Snow Survey and Water Supply Bulletin is planned for release by end of day May 9th 2016.
