Well just damn, looks like it's going to be a nail biter, and we will only have 24 hours to determine if we need to evacuate. Damn. Well good news is cat 3 will be surviveable (barely) where I'm at.
Where are you?..
Don't forget that last year Charlie exploded from a Cat 2 to a Cat 4 in four hours. I wouldn't expect that to happen with Rita as the conditions are pretty uniform as she crosses the Gulf, but you're going to have to make that decision no later than Thursday evening, and that's probably pushing your luck. It will be the mother of all traffic jams.
