Ch.11's Dr. Frank:
No sign yet of a turn further to the north, current track brings the eye over or just east of Galveston. May indeed come in at Galveston instead of Port Arthur. NHC is still calling for a High Island landfall, around 2am.
Galveston news conference:
If a High Island hit, Galveston is expecting 75-90mph winds, the worst likely from 8pm-midnight. 7' surge level on the island.
If you live in the storm surge danger area, YOU CAN STILL EVACUATE. Very little traffic on the roads, check for yourself on the traffic cameras:

And the traffic speed maps:

The northernmost camera on I-45 is very close to the choke point where the freeway narrows from 4 lanes northbound to 2. So while there may be backups further north, it is nothing like yesterday (8 lanes stop and go at 2am this morning) and you will be able to stay ahead of the storm. I-45 is open now past the bus accident site, which is just south of Dallas. If you are unsure of your safety in a storm surge, LEAVE! Storm surge is the big killer.
Here are storm surge maps to doublecheck:

Dr. Frank has a history of being a drama queen in storms. I trust the NHC more then him.
