It seems like there might be some confusion in your question. If you're referring to "Ryder" as a company or entity that is adding features to "Everest's Snow Cloud," it's a bit unclear what you are referencing, as "Everest's Snow Cloud" doesn't appear to reference a well-known application or feature set.
If you're referring to the Everest region and snow conditions, or something related to snow cloud features for weather forecasting or outdoor activities, more specificity would help!
However, if you meant "Ryder" in a tech or logistics context (such as Ryder System, Inc., a transportation and logistics company) or another context entirely, please clarify that as well.
Please provide more details or context so I can give you the most accurate information!
