Snow Conditions Commentary
March 23, 2020
The provincial snow pack continued to increase in the first week of March due to unsettled weather conditions. Very stable and dry conditions persisted over the following two weeks of the month. The snow pack has remained fairly stable over that time. Weather forecasts for the final week of March show a return to storm activity and additional mountain snow accumulation through the province.
The current average of all automated snow weather stations (ASWS) across the province is 108% of average, compared to 111% of average on March 1st, 113% of average on March 8th and 111% of average on March15th.
Current % of average values range from a low of 77% on Vancouver Island to a high of 129% in the Okanagan. Most areas of the mountainous BC Interior, including the Boundary, Okanagan, Upper Fraser – East, Upper Fraser – West, and West Kootenay continue to have high snow packs (>120%).
By Late-March approximately 90% of the annual snow pack has accumulated. With another 3-6 weeks of accumulation still to come, changes to the snow pack are possible. Historically, April is an unpredictable month regarding snow pack. If the weather becomes very warm, the snow pack begins melting and lower the risks of flooding later in May and June. If the weather remains relatively cold and stormy, the snow pack can still increase considerably.
