Daily Snow Forecasts

US and Canada
All eyes on Hurricane Ian, warm but unsettled out West
Updated 9 hours ago Alan Smith
Hurricane Ian is set to make landfall in Western Florida on Wed as a major hurricane. As this storm slowly moves north, it will bring heavy rains & gusty winds to the Southern Appalachians Fri to Mon. The West has been very warm recently, but a slow-moving storm will bring showers, t-storms, & a little bit of high elevation snow to the PNW & Rockies over the next several days.

2021/2022 Season Recap
Updated 4 months ago Bob Ambrose
The 21/22 La Nina Winter pretty much delivered as advertised with above average snowfall west of the Continental Divide, and generally below average snowfall for resorts east of the Divide. Highlights included a snowy December for the westside putting many operations in good shape for the Holidays. East of the Divide saw one of the snowiest April’s in memory, but it might have come a tad too late.
