8am: Increasing divergence ahead of landfall

8am Hanna Computer Models

Here’s the 8am model runs. Note the increasing amount of divergence ahead of Hanna’s landfall. There’s still reasonably strong agreement for the Horry County landfall scenario, but I would not be surprised to see the track jog west a bit more before it’s all said and done.

The 8:00 advisory slows Hanna’s forward motion down ever so slightly (to 18 MPH instead of 20). It’s still headed northwest. Winds are still 65 MPH, but the pressure is down a bit more. Satellite imagery is indicating that the shear has backed off some; note the gigantic plume of convection trying to wrap itself around the center. A hurricane at landfall is reemerging as a possibility.

Stay tuned…

    Agreed in fact as the convection begins to begins to increase near the center the outflow also looks impressive. With a pressure down to 980 and being in improved conditions and over the gulf stream I wouldn’t be surprised that Hanna is a Hurricane when it makes landfall overnight…. I plan on discussing this later on my site…
