Why Ike Could Be Texas' Worst Nightmare

The unnamed Category 4 hurricane that slammed into Galveston, Texas Sept. 8, 1900 remains the deadliest ever to hit the United States, having killed at least 8,000 people (estimates vary) and leveling virtually the entire town. Credit: NOAA

From Live Science:

As Hurricane Ike revs up again over the Gulf of Mexico, residents of coastal Texas, especially Houston and Galveston, are preparing for the arrival of the monstrous storm, which could be the most devastating that the Lone Star State has seen Hurricane Alicia came ashore in 1983, causing nearly $6 billion in damage and 21 fatalities.

Ike is huge. Hurricane-force winds extend out 120 miles (195 kilometers) from the storm's center, and tropical storm-force winds reach out 275 miles (445 km), both measurements exceeding what's seen with many storms. Ike could reach major hurricane status as a Category 3 before it makes landfall late Friday or early Saturday morning somewhere along the Texas coast.

And right now it looks like that somewhere will be the Houston/Galveston area.

How Strong Can A Hurricane Get?

From Live Science:

Hurricane Gustav, churning toward the Gulf Coast now, has a small chance of becoming a Category 5 storm before it makes landfall, according to the National Hurricane Center. That would put its winds at 156 mph or stronger. Such winds would devastate most buildings and trees in the storms path. Little would be left standing.

There is no such thing as a Category 6 storm, in part because once winds reach Category 5 status, it doesn't matter what you call it, it's really, really bad.

Category 5 on the Saffir-Simpson hurricane scale has no upper bound, on paper. But in theory, winds from a powerful hurricane could blow the scale out of the water, scientists say.
