The "happiest place on Earth" became host to a spooky, ominous sight as the sky turned grey and made people at Florida's Walt Disney World wonder whether a tornado was about to strike.

Visitors at the Orlando theme park spotted a large, dark cloud forming over Disney World's EPCOT on Thursday, according to News 6. Some wondered if it was a funnel cloud, the sight of which is usually seen as a precursor to tornados.

Pictures and videos were shared on social media as surprised park visitors witnessed the doomy sight.

"I was there tonight when the sky got really dark really fast. The rain has been unbearable this year," one Reddit user wrote. Another said, "That's just Maleficent...up to her old shenanigans."

"Me who lives 10 minutes from disney and had no idea," one comment read.

"This is such a crazy, but beautiful picture," another user added.

One Twitter user wrote to National Weather Service Melbourne on social media and asked, "scary cloud club here or a funnel cloud, what are we thinking."

The user received the response, "it is a potential funnel cloud."

However, others say that it was a scud cloud that appeared in the sky. Scud clouds are often mistaken for funnel clouds because they may appear to have a bit of rotation.

"Scud clouds are often mistakenly called wall clouds or funnel clouds," the National Weather Service wrote on its website. "In reality, these are just rising clouds due to increased low-level relative humidity. They will not rotate and will rise slowly."

Funnel clouds rotate strongly, and most tornados start with them, according to the Independent Herald. On the other hand, scud clouds are connected with severe thunderstorms and are, otherwise, harmless.

News 6 meteorologist Samara Cokinos said the system that was captured by Disney World visitors Thursday is most likely a scud cloud, especially because no severe weather warnings were issued in the state at the time. However, Central Florida was given storms and flood advisories throughout Thursday afternoon.

News 6 meteorologist Jonathan Kegges echoed Cokinos' view.

"Like Samara said, this could just be a scud cloud, which is a jagged cloud that gets sucked into the updraft of a thunderstorm," Kegges said, according to the outlet. "Often times, scud are incorrectly identified as funnel clouds or tornadoes."
