Typhoon Lagoon closes for hurricanes.
That’s how it came into being in the first place, or so the story goes.:laugh:
I’ve never seen it close outright during a thunderstorm, mostly because I haven’t been near one during a thunderstorm, but I do know that most amusement parks across the US close tall rides whenever lightning is detected within 5 miles of the park until radar shows the storm has moved off. I also know that most pools and waterparks will close, or at the least, evacuate all pools and waterslides during storms.
If it’s just raining, I haven’t seen either Disney waterpark close.
