For the next December Holiday Update, there should be a huge winter vortex that sweeps through Forza Horizon 5 and provide snow levels not seen since Forza Horizon 4! All 4 weeks should fall into winter. The Volcano Cauldron would have the most snow, while the desert and beaches just get snowflakes to make it most realistic. Then a temporary winter ski lodge and garage could be the seasonal outpost on top of the mountain.
