If you live in coastal Texas - particularly the area around Galveston - please turn off your computer, grab your evacuation kit and get the hell out of coastal Texas. Do not drive towards Louisiana. You might be able to get away with back roads out of major urban centers, provided that you leave right now and listen to the entire traffic report, instead of just the bits involved in your commute.
Why are you still reading this? Stand not on the order of your coming but go at once!
PS: Good wishes and prayers to everyone in the region, including those leaving it with all due speed.
