2018-2019 Western United States Snowpack Recap

If you've been following OpenSnow throughout the 2018-2019 season, you'll know that this has been a winter to remember. Storms ramped up across the Western US in November and continued to deliver consistent powder days to nearly every region.

Most resorts are now beginning to shut down their lifts for the 2018-19 season but there will still be plenty of time to enjoy the deep snowpack well into May, June, and even July!

Notable Projected Closing Dates

The map below shows the percent of snowpack compared to the average snowpack for April 12, 2019. Red is well below-average, yellow and green are below to near average, and blue/purple is well above-average. This is based on the weight of the snow on the ground, measured by automated backcountry weather stations called SNOTEL.

The following Base Depth vs. Average graphs are updated daily on OpenSnow and available to All-Access members for nearly every mountain location in the western US and Canada.

Thank you so much for following OpenSnow this season, have a great summer, and we'll see you right back here for the 2019-2020 season!
