Hanna’s looking rough this morning. It’s back down to 65 MPH winds, and there’s a lot of speculation that Hanna is becoming extratropical. NHC acknowledges Hanna’s struggle to remain tropical in the discussion:

VERY DRY AIR ASSOCIATED WITH THE UPPER-LEVEL LOW OVER THE
NORTHWESTERN BAHAMAS IS CHOKING OFF CONVECTION NEAR THE CORE OF
HANNA…AND THE CYCLONE HAS A VERY SUBTROPICAL APPEARANCE.
CONVECTION HAS DIMINISHED SUBSTANTIALLY OVER THE PAST 6-12 HOURS
AND THE HIGHEST FLIGHT-LEVEL AND SFMR WINDS HAVE COME DOWN AS WELL.
BASED ON SOME 52 KT SFMR WINDS AROUND 11Z…THE INITIAL INTENSITY
IS LOWERED TO 55 KT.

Here’s the latest track, which returns more to the rightward path that we started seeing emerge during the day yesterday before the 11:00 came out:

The wind field is still pretty broad — 310 miles, to be exact — but largely to the north and northeast. We in Charleston still stand a decent chance of seeing tropical storm force winds for a time, and some rain, but with the dry air influencing the storm as well as the continued rightward bias in the models, impacts along our coast will be lessened.

News 2 reports that Gov. Mark Sanford has called for voluntary evacuations of Horry and Georgetown counties; he also said that Hanna might be a “dress rehearsal for a thing called Ike.” Ike is bothersome to me; I’m crunched for time now but will have more later on.
