Augustine's Anafi sat in a tree for 6 months in a Canadian winter and still works fine except for the damage caused by the crash itself. I've seen other videos in light rain or fog with no apparent problems.
However, I would never fly mine deliberately in rain, but it seems that it could handle it. Putting it away wet is an entirely different proposition! If mine got wet in a fast moving shower exactly like I experienced an hour ago, after shutting it off and bringing it inside I would use a hair dryer on low to thoroughly dry it.
With my previous practice drones, crashes into the snow were routine, and I used a Q-tip twisted into a point to suck little beads of water from wherever I could reach in the motor housings. With the Anafi, the only place you could reach with a Q-tip is the top of the motors, and the hair dryer would probably work better. Other areas of concern would be the hinges on the legs and the camera gimbals.
