Why a Storm Surge
Can be the Deadliest Part of a Hurricane
It can start before a hurricane even makes landfall.
Storm
surge, or coastal flooding, tends to be the deadliest aspect of
hurricanes. As wind from the storm pushes water onshore several feet
above the normal tide, it can trap people in their homes, wash away
entire houses, and make rescue missions harrowing and slow.
👇 🌊 👇
In the
US, the Eastern and Southeastern coastlines are among the most
vulnerable areas for storm surges. Along the East Coast, hurricane Sandy
produced a massive storm surge in 2012. On the Gulf Coast, places like
Galveston, Texas and New Orleans have seen multiple hurricanes so
they've built some infrastructure to help defend against excessive
flooding. Levees, canals and seawalls are designed to stop or redirect
rising water away from cities. But even those can be inadequate, when
faced with an especially strong hurricane.
What really concerns experts, though, are places that don’t experience a lot of hurricanes but are still vulnerable to storm surge, like the coast of Georgia and Northern Florida. These areas have shallow water, which means sea level can rise faster and water can reach further inland making the flooding worse. But they’ve seen fewer hurricanes than the Gulf Coast and they are likely to be less prepared.
So when a major hurricane like Irma hits low-lying areas like these, the storm surge can be the first and deadliest thing headed their way.

What is a Storm Surge
A storm surge is a change in sea level from the usual predicted tidal water levels driven by weather systems.
With nearly half of the world's population living near the coast, many are at risk of the destructive impacts of storm surges.
In this video, we look in detail at what drives a storm surge and how the direction of the wind, the shape and depth of the sea floor and coastal area can affect surge formation and height.
Because this is an in-depth video, links to supporting videos that cover some of the concepts discussed will appear at appropriate times.

Hurricane Ian one of the strongest to hit the U.S. in decades
MSNBC's Ali Velshi joins Shep Smith to report on the damage wrought so far by Hurricane Ian, a category 4 storm that is one of the largest ever to hit the state.

But a mobile phone video filmed during Hurricane Ian’s assault on south-west Florida isn’t just another fishy story.
A large, dark fish with distinct dorsal fins was filmed thrashing around an inundated Fort Myers backyard. Experts were divided over whether the clip showed a shark or another large fish. Nevertheless, some Twitter users nicknamed the hapless fish the 'street shark'.

Man Films Possible Shark
in Floodwaters after Hurricane Ian
After Hurricane Ian struck Florida, causing widespread flooding and devastation, a man in Fort Myers spotted something peculiar in the flooding outside of his home. It looked like a shark fin peeking out of the water. Dominic Cameratta quickly filmed the animal swimming between the homes in his neighborhood.

Hurricane Ian:
One for the History Books
Four
days after Hurricane Ian made landfall in Florida, and then again in
South Carolina on Friday, there are dozens dead, millions without power,
and billions in damage. Correspondent Kris van Cleave reports on the
aftermath of the catastrophic storm.
