Reliable, must-have tool

This resource (and the website) is a must-have. All-access is very much worth it alone, but you get OpenSummit subscription with it. I read the snow and weather forecast every day Joel and the others prep. Going to an unfamiliar area, like Colorado->Tahoe? Pull up OpenSnow and realize why their can have rain at the lake and snow on the summits.

Also, their accountability for forecast accuracy stands out. They discuss their prediction vs. reality (retroactively) and it's very informative for understanding mountain weather generally. They will explain when and why their forecasts were wrong -- show me another major weather forecasting website/service that does that! I backcountry ski often, and hike/climb high peaks often in the summer, and OpenSummit's peak-specific forecasts are a crucial tool in assessing mountain weather (along with other resources to confirm, of course). Cross-reference resources.

Fantastic! Reliable and informative

I love this app! I use it daily to plan my snowboarding trips throughout the season. It's more accurate than generalised weather apps and when combined with the reports from my local mountains I always know exactly what to expect for the day, from road conditions to primary and secondary snow surfaces, avalanche conditions and the amount of lifts/mountain areas open. It's well worth the all-access subscription especially as someone with a season pass - and even more essential when you've got a job you can't just take off from whenever you want, so planning is key!

Other snowboarders and skiers always ask what app I'm using when I pull it up or post a screenshot, then immediately go download it themselves - it's a step up from everything else out there for sure!

Best weather app

Top notch daily weather reporting and analysis makes this a must have tool for anyone who needs more info than a sunny/cloudy/snowy icon in a basic weather app. Founding meteorologist Joel provides unmatched weather/snow reporting for the Colorado Rocky Mountains which is the content I access, although there are many other local experts providing snow updates for other regions. I have a snow plow business in the Colorado mountains and this app is my main source for information about incoming weather that will affect our area. If you’re an out of town tourist trying to figure out what our weather will look like during your vacation then use the resource the locals use, welcome to Colorado, and remember to stay in the right lane except to pass!! Thanks again Joel -Scott
