Most models agree that Dean will reach Cat 5 before slamming Mexico twice. While Texas is not entirely out of the woods yet, odds are that Dean (unless he slips past the ULL and ridge) will not be a threat to the United States.
There is the possibility of a “homegrown” storm by the middle of next week, and a vigorous wave off of Africa (which remains disorganized) could play the role of “Dean..Part Deux”.
Dean has not entered the gulf yet, and if he stays south, may not enter at all. However, he is at a point to where his forecast path could be completely different from what we expect. So, in short, not an “ALL CLEAR”, but more of a “Mexico, get ready.”
