A few things:
1) That tends to happen when a ride with a wind limit of about 20 MPH runs in wind speeds that are 3 times that. The ride didn't do anything out of the ordinary here. Obviously the park didn't mean to run the ride in those conditions and it was a very sudden gust but they did and the ride's backup systems seem to have functioned as designed.
2) As for the specifics of what happened, thats above my pay grade. I think Rob Von Roll has an account here so maybe he can drop some knowledge. This is what I've gathered but all of this information basically comes from his posts so full credit to him and my apologies if I misinterpreted anything.
One of the main reasons that the ride can't run in high winds is that the cable can come off of the rollers on the tower. If it comes off towards the tower then it rests on the mechanics that support the rollers (which have a name but I don't know what that name is), if it comes off the other way there's a cable catcher on the outer frame so they definitely designed these rides with this scenario in mind. Apparently it came off towards the tower battery. Thanks to these backup systems the riders are totally safe but if the cable isn't on the rollers then you obviously can't bring the cabins in. This is a model, but basically this is what happened
. The cabin wasn't going anywhere, but unfortunately "anywhere" includes "back to the station".
3) In order to get the cabins back to the station they need to adjust the counterweight to pull tension off of the cable, put the cable back on the rollers, put the tension back on the cable and bring them in with the backup motor so I would expect the ride to remain closed for a few days at least because it sounds like a real pain in the ass.
4) Someone should tell the fine people of San Diego that 49 degrees is not "freezing cold". Shut up.
