@Korina Ok I found the compare function from the posting https://community.windy.com/topic/9427/how-to-use-the-compare-feature
This is nice but I would recommend adding a graphic display of the track as it is moving such as with the present hurricane heading toward Florida.
Seeing both the European and GFS models displayed graphically at the same time would be a nice feature. One could be primary and the other secondary has shown as just a dotted line for the projected path. Thank for your time Don.
