Weather Service: Evacuate Galveston or Face 'Certain Death'

I've never heard the National Weather Service issue such an ominous warning, this in regards to Hurricane Ike, which is forecast to push up to 25 feet(!) of storm surge through Galveston Bay tonight and tomorrow.

Heard that on the radio this morning. I'd believe it, too. Look at the size of this thing!
