Extremely rare footage shows the power of Hurricane Irma, and it literally changed the coastline in some areas.
Twitter user @Kaydi_K from Long Island, Bahamas witnessed the phenomenon and shared a video which shows the shoreline receded much further than normal, exposing what is usually the ocean floor.

The bizarre and somewhat eerie video is a result of the hurricane’s low pressure and sheer strength, causing surrounding waters to be sucked into its core, the Washington Post reported.
It may be a case of a hurricane “bulge” effect, said Angela Fritz, deputy weather editor for the Post, in which very low pressure in the center of the storm acts as a sucking mechanism, drawing in air and pulling water from the surrounding area.
Some Twitter users were concerned since receding shoreline that exposes the ocean floor is often a sign a tsunami is approaching. However, Fritz said the water will not rush back rapidly.
The International Tsunami Information Center notes on its website when the sea drains away to not investigate because this is a typical sign of an incoming tsunami.
