Snow conditions commentary

A bi-weekly commentary of snow conditions based on readings from the B.C. Automated Snow Weather Station (ASWS) network is published during the snow season.

April 1, 2025

Precipitation events continued for the second half of March, particularly in the southern half of the province. Mountain snow accumulation trended above normal during March.

A complete listing of Automated Snow Weather Stations (ASWS) expressed as percent of long-term median for the entire length of record is found in the ASWS Weekly Summary (PDF, 186KB)*. Hyperlinks to interactive plots are available for each ASWS in the table.

*Note: These are not the official snow basin indices. 

The provincial average for April 1st at all ASWS sites is 88% of the period of record median, increasing from 83% on March 15th. The Fraser River basin stations averaged 90%, which increased from the March 15th value of 83%. By April 1st, on average, approximately 95% of the total seasonal snowpack has accumulated.

As of April 1st, the ASWS's measured significant increases in snowpack since March 15th in the following regions, Lower Fraser (+17 percentage points), South Coast (+12), Liard (+10), and Vancouver Island (+9). There were no regions that measured significant decreases since March 15th.

A provincial composite graph of all automated stations with relatively long-term record is shown below. The data for the graph begins in 1988. 

 

^{From the above graph, the April 1st percentage of average is 82% (March 15th: 76%) and at the 8th percentile (March 15th: 7th).} 

The April 1st, 2025 Snow and Water Supply Bulletin is scheduled to be released April 9th or 10th, 2025, based on data availability. The April 1st bulletin is considered the primary bulletin for historic seasonal snowpack comparison.  The official Snow Basin Indices are calculated within the Bulletin.
