I've had this open, most of the day, hitting the refresh button lower on the page. Watching it this long, this thing "seems" to be heading MORE towards LA than TX.
It is actually wobbling west and then north, but if you draw a line, it is headed to Galveston, in a due northwest direction. But the weather gods say a high pressure system in Oklahoma moving east, will push the storm east tomorrow. There is still quite a bit of uncertainty, as shown by the odds map. This storm is not as locked into a path as Katrina apparently was.
If she keeps going in a straight line in the direction she's been moving in those last few frames, she'll hit east of Port Arthur.
