If the storm is gonna be coming ashore over, say, Freeport TX then it seems that landfall will overlap the Sat morning high tides (7-8am or so). That's not good..
The guessing for landfall is very late Friday night or pre-dawn Sat AM. So the tides may be inbetween (but it is only worth a foot + anyway, and the surge is over 20 feet, so it doesn't matter much). But speed of the storm seems to be one of the most unknown variables in any event. One just doesn't know.
And high tide appears to be somewhat significant there (unlike NOLA/Mississippi); somewhere around 4 feet.
