Re: ATL: HANNA - Hurricane - Discussion
When it does tighten up and swing that south band around corpus is going to get hammered, 50-60 mph gusts here, been driving out by the ocean dr, got interviewed by channel 4 SA news while I was there. The storm surge is wicked already and the wind is blowing doors out of the gas station. #factsnotfear

hmmm...
104 kt at 6,800 ft
101 kt just below 6,000 ft
99 kt at 4,500 ft
This should eventually mix down to the surface, also at that rate, assuming a linear change this suggests about 85 to 88 kt at the surface. All things pointing to a Cat 2 real soon.

Looks like the HUrricane man will have to wait for his 50th Eye penetration if he stays where he is at.

Hanna managed to find the farthest west point it could to make a Gulf U.S. landfall.

The eye appears to be contracting rapidly now that the western eyewall has begun hitting the coast..
last chance to deepen is now..

What if the Atlantic is playing with us

If that eye fills in completely on the west side, it will be roughly 25 miles wide. This would also delay landfall by a couple more hours.

dBZ (should be typed like this) is a measure of energy return to a radar (reflectivity)

It's a measure of radar reflectivity: https://en.wikipedia.org/wiki/DBZ_(meteorology)

I thought the feeder band was falling apart as it got inland.
I was wrong, its just snapped back big time.

Here we go.
Tornadoes may be the worst part of it.

AF307 plane is recording consistent >80 kt FL winds, and it’s still not at the center.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.
