Snowpack readings hit worrying lows

British Columbia’s snowpack is splitting sharply by region, with Vancouver Island and the Okanagan heading into spring far below normal. (gov.bc.ca) The B.C. River Forecast Centre said the provincewide mountain snowpack was 92% of normal on April 1, 2026, but that average hid a “strong regional divide” between wet northern basins and dry coastal and southern Interior ones. April 1 is the key benchmark because about 97% of the annual snowpack has usually accumulated by then. (gov.bc.ca) B.C.’s April 1 basin map put Vancouver Island at 44% of normal and the Okanagan at 58% of normal. Reporting on the same release said the Okanagan reading was the region’s lowest since tracking began in 1980. (globalnews.ca) (gov.bc.ca) Snowpack is the water stored in mountain snow before it melts into rivers, reservoirs and streams. The River Forecast Centre said low snowpack in coastal and southern Interior basins raises early concerns that drought conditions could build through spring and summer. (gov.bc.ca) (arcgis.com) The same pattern is showing up south of the border. The Coeur d’Alene Press, citing the April Idaho water supply outlook, reported Panhandle streamflow forecasts for April through July at 48% to 91% of normal at the 50% exceedance level. (cdapress.com) Idaho’s statewide snowpack peaked on March 17 at 68% of normal, nearly three weeks early, and about 25% of that snowpack had already melted by April 1, according to reporting on the Natural Resources Conservation Service outlook. The report said this year’s snowpack was among the lowest on record since measurements began in the 1930s. (cdapress.com) (capitalpress.com) Warm winter and early spring weather are a big part of the explanation. The North American Seasonal Fire Assessment said southern British Columbia’s mountains and inland valleys saw less than half of normal precipitation in February, while Idaho reporting said a mid-March heat wave rapidly melted even high-elevation snow. (nifc.gov) (cdapress.com) Low snow does not automatically mean a severe fire season, but it removes one of spring’s main moisture buffers. B.C. wildfire forecasting says the service uses snowpack, drought and fire weather together for seasonal planning, and regional reporting has linked the thin southern snowpack to elevated early fire concern. (gov.bc.ca) (lmtribune.com) (radionl.com) The next checkpoints are May 1 snow surveys in British Columbia and updated water outlooks in Idaho. If spring stays warm and dry, the problem shifts from low snow on the mountains to low water in rivers and drier fuels on the ground. (gov.bc.ca) (localnews8.com)
