The bulletin released by B.C. said precipitation was well below normal last month, with the last two weeks in January bringing “extremely dry” conditions.
B.C.’s average snowpack was 28 per cent below normal at the start of February, after an “extremely dry” start to the year across much of the province.
The latest snow and water bulletin, released Tuesday, came after B.C. started the year at a more typical level, hitting 13 per cent below normal on Jan. 1.
Jonathan Boyd, a hydrologist with B.C.’s River Forecast Centre, said it was strange to see such a significant drop in a single month, especially in January, when the province typically gets the greatest accumulations of snow each winter.
“It essentially was the lowest accumulation from the stations that we have automated for that January period,” Boyd said of the province’s automated snowpack stations, with records dating back to the late 1980s. “So, just a really dramatic shift.”
The bulletin released by B.C.’s Ministry of Water, Land and Resource Stewardship said precipitation was well below normal last month, with the last two weeks in January bringing “extremely dry” conditions. It fell within the top 10 driest Januaries across much of the province since record-keeping began, while Abbotsford, Penticton, Kelowna, Vernon, Cranbrook and Chetwynd were in the top five.
Moderate precipitation over the southern half of B.C. in the last few days of January prevented several locations from hitting record lows for snow.
“We were at least lucky to get a little brief reprieve at the very end of the month, because it still could have been that much worse,” Boyd said.
The average snowpack across B.C. was 72 per cent of normal at the beginning of February, higher than the 61 per cent recorded on the same date last year.
February has also been very dry so far, said Boyd, adding the latest information he had received from Environment Canada indicated it may be another seven to 10 days before there is potentially a significant change in weather patterns.
There’s a high degree of variance in snowpack across regions, ranging from 20 per cent to 108 per cent of normal. The western Upper Fraser basin was sitting at 92 per cent, while snowpack in the Similkameen was at 57 per cent of normal.
Areas with below-normal snowpack show “early concerns” for drought conditions in the spring and summer, the provincial bulletin said, while areas with near-normal snowpack may have a higher risk of melt-related flooding this spring.
There are a couple of months left in winter and the snowpack could still change significantly, it said.
Still, Boyd said the coming weeks and months would need to bring record-setting snow to hit 100 per cent of what is considered typical.
“You’d almost have to have from (now) to April 1 be the absolute snowiest six weeks that we’ve ever had to just get the numbers back to normal,” he said.
