It's very clear that most of you don't know a lot about ski lifts and don't have a lot of experience riding them.
Many gondolas that are built today DO NOT HAVE CABIN PARKING. In other words they don't remove the cabins from the line for weather events. If weather suddenly arrives Disney is more than likely NOT going to remove the cabins from the various lines. They stay put.
Second, YOU DO NOT rope evacuate a lift unless there is no way for the lift to operate. If wind or weather suddenly arrives the best practice is to stop loading and continue to run that lift at a reduced speed or with stops and starts to unload the remaining riders. If the wind is too strong to run at all then then riders remain on the lift and you wait. Only after an extended period or if the riders were in immediate danger would you rope evacuate the lift. Rope evacuations take a lot of time and should be avoided until absolutely necessary.
The manufacturer (Dopelmayr in this case) determines basic safe operating conditons for the lift. Some of the determination however is decided visually by the operator. Anemometers mounted on the towers and nearby areas monitor weather conditions. The control computer will stop a lift when wind (speed and direction) doesn't allow for safe operation. Wind speed, wind gusts, and direction determine when a lift can operate and at what speed (this is the second part).
Most lifts have thresholds for operations. There is point where wind speed and direction will necessitate the slow down of the lift, but not the closure and there is another point where it necessitates the shut down of the lift. If the wind is variable (gusting) then the lift may be in a situation where it may operate, but may slow and stop periodically as necessary to account for the wind gusts.
