ATL: SALLY - Post-Tropical - Discussion

[hurricaneCW]

This is gonna be really bad folks, the storm is barely onshore and extremely slow moving.

We already have 20"+ totals with a doubling expected. Pensacola area getting the brunt right now.

Thermal profile almost 7 hrs ago.
Says a lot.
Classic warm core and very deep cold pool.
Not vertically aligned indicating strong shear.
CIMSS estimated 30+ knots of shear yet she was able to hold her own.
Due in large part to the deep cold pool.
Convection was driven by the interaction of shear with the cold pool.
Horizontal vorticity driven by thermal gradients along the edge of the cold pool created updrafts.
Updrafts were accelerated by the vertical shear.
This accounts for the pulsing behavior of hot towers during the life of the storm.

So rather like Michael and Laura, Sally was riding just on the wrong (from the perspective of those in the impact zone) side of the fine line between shear enhancing the convection, and disrupting the cyclone.

Yup, looks that way. Very interesting.

That guy needs to run out the driveway and get his souvenir.

Looks like a big mesovort about to come onshore.

Winds here have yet to calm. We have been on the edge or the strongest portion of the inner eyewall for hours. One of the cars out in front was moved across the parking lot by the wind alone..

[supercane4867]

Sally's wind impact is on a par with Ivan. It might be even worse due to prolonged effects caused by the slow movement of the storm.

Looks like Pensacola is going to take a nasty hit.

Stay safe my friend.
