could you please tell me what version of Firefox are you using and which OS?
I checked the functionality on Firefox 60 + Windows 10 and there is no problem in rendering Wind animation nor any issue with purple layer.
@rittels Thanks! I'll check it out!
I'm still would like to hear some feedback on my latest request from developers. Right now, there is no way to use the app when you select "Distance & planning" option (long tap anywhere on a map), because you can't save the route and the rest of options are not available when you have selected "Distance & planning".
An older post I know, but this idea would be useful for emergency management and akin to IKE (integrated kinetic energy), but instead of an area average at a given time, this would be kinetic energy integrated over time for a grid point.
Windy uses timezone of your computer, but if you open a detail of a certain location it will show its local time.
Generally we use UTC or also referred to as GTM time.
