As Helene roared ashore as a powerful Category 4 hurricane, the U.S. Coast Guard saved a man and his dog from a disabled sailboat 25 miles off Sanibel Island, Florida.

The Coast Guard posted the video of the rescue from the 36-foot sailboat to their social media pages.

The system generated a massive storm surge and knocked out power to millions of customers in several states. 

At least six people were reported dead. 

The storm made landfall late Thursday in a sparsely populated region with maximum sustained winds of 140 mph in the rural Big Bend area.

That region is home to fishing villages and vacation hideaways where Florida’s Panhandle and peninsula meet. 

But the damage extended hundreds of miles to the north, with flooding as far away as North Carolina.
