Hurricane Category 4 Hurricane Helene

[Taylor Campbell]

The mesovortex are ripping in the eyewall. I see velocity bins in the 140mph range with a very large sector of 130mph +. Conditions are rapidly going down hill in Perry, FL!

Fingers crossed that the her path slightly east of prediction spares Tallahassee somewhat, putting it on the better side. Still going to be rough, but maybe not as rough.

Open eyewall?

 

[Richardjacks]

Open eyewall?

i think thats just radar attenuation

 

[wx_guy]

Mission #18 recon just reported 135 mph dropsonde at the surface. So maybe still strengthening.

Mesovortices circling the northern eyewall of Helene clearly visible in this loop from KTLH.

Wouldn’t surprise me. I see velocity bins in the 150mph category now with a very large area of 130-140mph.

Hurricane Hunters plane is punching the eye again

Wouldn’t surprise me. I see velocity bins in the 150mph category now with a very large area of 130-140mph.

I have a fairly large area of 150 - 158mph from KTLH on Radarscope. A few gust bins in the 180mph - 203mph area but those have shown up at times on scans for close to an hour.

ADT satellite method shows continued strengthening. Now at an adjusted T# of 6.6 and a raw of #7.0. Unbelievable stuff considering where it was 9-12 hours ago.

Hurricane Hunters reading Cat 5 winds at their flight level.

 

[wx_guy]

Yeah, Cat 5 at flight level, I'd imagine that's about 140 or so at surface.

Via WCTV, Taylor County's EMA director John Louk says around 500 people haven't left the county as Helene approaches.

And a pressure of 940-ish

 

[Julian]

This thing is crazy strong with the mesovortices and what not. Especially for an open eye wall on radar

 

[MMWX]

Still seeing lightning strikes in the northern eyewall. This thing is still strengthening.

 

[UncleJuJu98]

Not sure if it's just the northeastern side of the eyewall getting closer to radar and that's why the velocities are going up or if it's strengthening.

 

[Clancy]

Low-topped supercells have gotten going in SE GA and parts of SC.

The eye wall is not open. See the thread further back, the radar can't penetrate the full eye, it's actually fully closed.

Not sure if it's just the northeastern side of the eyewall getting closer to radar and that's why the velocities are going up or if it's strengthening.

Perhaps a bit of both.
