Snowpack levels above average for most of province: B.C. River Forecast Centre

Snowpack levels across British Columbia are nearly all above average, according to the latest provincial data.

In its snow and water supply bulletin, the B.C. River Forecast Centre says snow accumulation began early this year, and that there’s a 95 per cent chance that La Nina conditions will persist through the rest of winter and into spring.

The bulletin says the provincial average for all automated snow weather stations is currently 122 per cent, up from 115 per cent on Jan. 1.

“Accumulation in December was steady as the province experienced several storm cycles throughout the month,” reads a snow conditions commentary from Jan. 18.

“The first half of January was very stormy with several frontal systems affecting the province, particularly the South Coast, Vancouver Island and the Southern Interior and resulted in rapid mountain snowpack development.”

Regarding La Nina, the province says the weather pattern typically results in cooler and wetter weather conditions for B.C.

“The overall impact of La Nina on snow can be variable,” said the snow conditions commentary for Jan. 18, “but on average, areas in the southern portion of the province tend to have higher than normal April 1st snow basin indices.”
