A viral video posted to social media on Saturday shows how powerful the category 5 hurricane was when it plowed through the Caribbean. On the northwest side of the island, it would be blowing the water away from the shoreline.
She called it the hurricane "bulge" - where water is drawn into the centre of the storm and the shape of the ocean is changed.
"I am in disbelief right now.This is Long Island, Bahamas and the ocean water is missing!"
Hurricane Irma is strong enough to completely change the shape of an ocean.
She posted "There is no more ocean!" As the storm gobbles water towards its center, it gets pulled from its surroundings.
He also warned that the water will come back soon - and residents should be cautious, since the water's return may be powerful. You know they happen theoretically, but the chances of seeing the most extraordinary weather phenomena are slim to none.
According to the Washington Post, this rare phenomenon is caused by a strong hurricane and resulting low pressure, which sucks water into the core of the storm.
People were filmed walking on sand on Long Island in the Caribbean island that would usually be covered by the sea.
In any case, this isn't the sign of a tsunami.
It is expected to make landfall Sunday, hitting the Florida Keys, southwestern Florida and the Tampa Bay area.
