Only two hurricanes have been known to make a direct hit on Galveston Island.

The first one, is the Galveston Hurricane of 1900. That's what it's officially called since storms were not named back then.

It's considered the deadliest weather disaster in U.S. history.

Somewhere between 6,000 and 12,000 people died in the first few hours.

Storm tides reached up to 15 feet, flooding most of the island. The city was nearly destroyed.

Two years later, people in Galveston built a seawall to protect it from future storms, and it did.

In 1983, Hurricane Alicia hit the island as a category three storm.

The Corps of Engineers estimated the seawall prevented $100 million in additional damage.
