Daily avalanche and mountain weather forecasts have ended for the 2018-19 season. We will issue Weekend Snow and Avalanche Discussions every Friday at noon through May 24th and avalanche warnings as needed during that time frame.
Thanks to the many people who make the avalanche center a reality. It’s a remarkable community effort. From all of us, thank you for all your help, your donations, your observations, and your enthusiasm.
Please continue to support your avalanche community by posting to our public observation page.
Avalanches and avalanche accidents can occur on snow-covered mountains at any time of the year:
Terrain doesn’t get less complex or serious in the spring. Respect the mountains, maintain safe travel procedures, and keep your guard up.
If you see avalanches you can generally start an avalanche.
Spring weather can rapidly alter snow conditions and snow stability. Think about changes occurring over minutes and hours.
You can reduce potential exposure to avalanche hazard by traveling earlier in the day during periods of cold clear nights and warm sunny days.
Winter-like weather means winter-like avalanches. Expect the danger to increase during storms. Our mountains can receive snow any time of year.
Strong sun on new snow generally results in periods of elevated avalanche danger.
Other Springtime Hazards:
Glide cracks. Don’t fall in them and don’t loiter beneath them.
Creeks are opening.
Snow bridges are weakening.
Cornices will sag and fail.
Seracs may collapse.
Be safe and have fun!
