I consider myself Windy.com the best public weather web application by far and since years (I don't use mobile thus I don't know the app Windy.com - but I guess it is also good).

Thus I think it should participate to WMO International Weather Apps Awards. I'm working myself in software for weather national centers affiliated to WMO, and I know some professional forecasters use Windy at office; thus I think that winning such a WMO award (and I know it could), would be a good point for Windy.
