WOW one giant leap backwards

The old app had weather stations and report pins right on the map was very easy to use, helped make more informed decisions
Really wish the new app was better

Multiple issues

Offline cache feature not working for NWAC zones and Mt Hood zone doesn’t populate even when connected to internet. Would love to give this app 5 stars for what they’re trying to accomplish, but the execution is significantly poor for the NWAC regions at least.

Love this app!!!

Demystifies avalanche conditions, whether you’re going to the back country or just dreaming about it.

Great UX to access avalanche forecasts.

Simple quick way to access current and upcoming avalanche forecasts. Well done. Would be great to see more features like trip planning, slope evaluation, checklists, inclinometer etc for a one stop shop for planning trips to the back country.
