When a major hurricane hits, it is often the storm surge — the sea or gulf water driven ashore by winds — that poses the greatest threat to people’s lives and livelihoods. The storm surge that will accompany Hurricane Helene is expected to peak on Thursday night.

Helene made landfall at about 11:10 p.m. ET near Perry, Florida, with 140 mph winds, making it the first known Category 4 storm to hit Florida’s Big Bend region since records began in 1851.

As Hurricane Helene swept through Northern Florida, residents across the Big Bend area are grappling with widespread damage caused by a massive storm surge.
