Apparent Snow Drifts in Watopia

I’m on windows 11, v1.19.2 100145. I seem to have snow on the roads if Watopia. Is this a bug, or is my game needing some help??

Never seen that before?


I have seen it once before in Richmond, when I was, by mistake, sent there when I tried to join a meetup in Makuri.

Reminds me of cycling in Fuerteventura when the sand gets blown across the road.
