Hurricane Irma is so strong that it is pulling water away from coastlines, an unusual phenomenon taking place in certain areas of Florida's west coast. Irma's powerful winds first blow offshore, essentially sucking the water away from the coast.

The winds pulled water out of the Tampa Bay and into the Gulf of Mexico. Portions of the bay that had been filled with water Sunday morning were empty by the afternoon. Tampa's Office of Emergency Management tweeted a photo of people walking on Tampa Bay, which it said "is very low due to the storm."

"It is dangerous to be walking out there," according to a Tampa city official. Tampa resident Tim Scheu posted a video of his dogs playing on the bay's shallow water. "Now an effective dog park," he wrote.
