Snow Today has expanded spatial coverage from the western US and New Zealand to now include Alaska and four Canadian provinces: Yukon, Northwest Territories, British Columbia, and Alberta. Snow-covered area in March averaged across the western United States was 34 percent of average, at 209,000 square kilometers (81,000 square miles) of snow cover, ranking last in the 26-year satellite record. Snow water equivalent (SWE) decreased in all western states except Montana and Washington.
