Perry showing the difference between La and TX right now. "There's no need to panic. We have had a plan in place for a number of years."
Technically, we've had plans for this for over 100 years, since Galveston was destroyed in 1900.
That said, the current, highly detailed set of plans for this scenario is only about 4 years old. However, we know that at least part of the plan works - see the recent Katrina shelter work. By the way, all the big Texas shelters are now almost empty - Reunion Arena was to be empty by today. So we're reset and ready to go there.
TXCN: People unable to get out of Houston who wish to do so should call 311 in the city or 713 837-0311 in outlying areas. Your evacuation will be arranged.
