How storm surge is measured and what to expect when Hurricane Milton makes landfall

PORTLAND (WGME) — When a hurricane approaches, you often hear meteorologists and others talk about storm surge, but what does it look like and how is it measured?

As a hurricane approaches land, ocean winds push water ashore.

There is the normal sea level, which changes according to whether the tide is high or low.

Three feet of storm surge usually doesn’t cause too much damage, with only some flooding in areas just along the coast.

Six feet is a different story, and it’s important to remember the big waves at the top of the wave.

Once there is a foot or more, devastating impacts can occur, with major flooding along the coast and well inland.

We expect a devastating and potentially deadly storm surge with Milton, especially in and around the Tampa area.

The latest update shows the highest increase expected in Tampa and south toward Fort Meyers.

This is where more than 10-15 feet can be done.

North and south of these areas, less storm surge is expected, but impacts are still likely.

Here’s a look at some of the notable events in American history.

Katrina stands out with more than 25-28 feet of overburden.

You also had Camille, Ike, Hugo and Opal all peak around or taller than 12 feet.

So whether you’re expecting a few feet of storm surge or much more, whenever evacuations are called for in your region, it’s always important to follow orders.
