Disney World guests captured visitors trudging through the stagnant water, past abandoned strollers, while others took cover.
The Magic Kingdom was also hit, with one guest posting a video of herself sheltering until the thunder, lightning and downpour subsided.
Although flash floods are common in Florida, one guest commented on the video that the storms have been unusually bad this summer.
“This went on all night, the rain and thunder subsided but then it was crazy lightning all night,” the user wrote.
Inside the Magic also captured drenched guests adorned with plastic ponchos fleeing the park as lighting flashed in the sky above. The blog noted that Disney World is in for worse flooding in the future.
Rainfall in Florida has jumped 28% since 1958, according to the Environmental Protection Agency, and that trend is only expected to continue, the site said.
