They will announce at noon whether or not Victoria is to have Mandatory Evacuation. Port Lavaca has announced mandatory evacuations already according to a coworker.
There is discussion here that if mandatory evacuations are order, then you can only use highways designated as official Hurricane Evacuation Routes. Is that true?
Don't think so. There are too many Texas back roads in the area - so long as you are heading *away*, nobody is going to care.
The Hurricane Evac routes will probably go contraflow in about 48 hours if traffic warrants it.
