I think your Hurricane Heat content is getting a bit high there.

Rita is probably going to surprise a lot of people by sunrise. Hopefully, it will be the fact that she hasn't made Hurricane status.
On the other hand. With the prospect of intensification happening overnight.
South FL and the Keys could wake up to something they will not like to see.
Miami Beach has reported 39mph winds in the last few hours. I believe the bridges close to traffic at either 45 or 55mph.

Key West NWS office is indicating the storm surge could come at high tide. And with the Moon being one to two days from full. This would be an Astronomical High Tide.

If you live in the Keys...Get out now. Please don't wait til morning.
