Yes can confirm Colossus, SAW and Inferno had downtime as soon as it started raining - and at no point was the rain really that heavy. We were out in it so we know
Was a bit annoying - I did think it was odd when explaining it to my non enthusiast mates as to why Nemesis Inferno was shutting as I was sure that wasn't normally the case with rain (there wasn't even any wind today either). The "uncomfortable for riding" message was played then a few minutes later the ride was closed with an announcement from the control room.
Was a minor annoyance for us today (as everything was walk on/5 mins anyway) but can see this being a big cause of delays if we have a "British summer" Colossus and Nemesis Inferno peaked at 15/20 mins after shutting down. Highest queue I saw was IAC when it was raining outside at 25 mins. Did that for the first time ever today. It's cringey I'm sorry, I give it until the end of this year. Found the whole thing rather odd and awkward , the theming was pretty good though.
Spotted that Colossus has heaters under the track in the station (but then I haven't been since October last year).
I witnessed a lift hill stop on Storm Surge in the rain but that could've been someone messing about in a boat... team member was on the stairs.
Was super glad to get on Slammer today <3 Persuaded my mate to go on when I explained how rare a ride it is. Samurai was testing late in the day.
Shout out to the crazy team member on SAW singing "Put Your Hands Up" and then asking me what he should sing (I suggested Macarena and he did haha)
