Yup, neither is my application.

Javascript is blowing up with:

"Redirect from 'https://www.windyty.com/gfs/2016/11/01/17/j1/0/5/wind-surface.jpg?0112' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://dev:8001' is therefore not allowed access."

Maybe it is missing an update in the js to use windytv instead of windyty?
