5. Hurricane Damage, con’d Wind/Flooding
There are so many images on the internet for hurricane damage, that dozens of slides could be added to this presentation. The key here is that strong hurricanes can literally level coastal cities. But the strong winds do not travel very far inland. Generally, the winds die off 10 mph for every miles the hurricane moves inland. So a Category 5 storm with winds above 156 mph might be only a Category 1 hurricane when the eye is 100 miles inland from the coast.
Land surfaces act like brakes on a hurricane’s rotation.
High winds and flooding are two of the most common causes of damage during a hurricane.

6. Hurricane Damage
Tornadoes can also cause damage in hurricanes because they can be embedded within rainbands.
Tornadoes are called water spouts when they occur over water.
Tornadoes form within hurricane rainbands because of the swirling winds within the hurricane. When winds moving in opposite directions collide, a tornado can form.
Tornadoes in hurricane rainbands can occur, but they are not always present.

7. Hurricane Damage
The most extreme forms of damage from a hurricane are along coastlines.
Here, only a single home remains standing along the Texas coastline after Hurricane Ike hit in
Hurricane damage along a coastline is the most severe because of high winds, pounding rain, and the storm surge.
The photo above was taken after Hurricane Ike hit the Texas coastline in The level of damage is almost 100%. This level of catastrophic damage only occurs when a very strong hurricane hits a coastline at high tide.
Why? Because the storm surge plus the high tide brings pounding surf further inland than if the hurricane storm surge hit at low tide. This was the case in Hurricane Ike.
Thus, sometimes the same strength of a hurricane might cause very different levels of damage depending on when and where each storm hits the coast.
The next slide explains a storm surge.
