It wasn’t due to weather, it was just down most of the day. Then we finally got inside and a storm rolled through and they kept making announcements like “inclement weather is approaching which may cause Journey of Water to close”.
I have no idea if they did close during the downpour, I’m guessing yes, but after it passed and we spent some time near the end when we exited people were entering so if it did close it went right back up.
