ATL HANNA: Extratropical - Discussion

[deltadog03]

I see, that one spinning SW...Looks like there might be another one?? new one?? just on the west part of convection.

If you go here

You can still get a decent close up using the old IR2. I have no idea what the heck they were thinking with this new scheme, I mean just remove all color and it's pretty darn good to begin with.

[eastcoastFL]

can anyone give me coordinates for the center? i am having a hard time locating it and i want to see if she has gained any lattitude.

[windycity]

Hanna is experiencing what we knew would happen for the short term. Now, will she rebound, and come back stronger? Maybe. I think its a safe bet to say for the next day or so, she probably won't " bomb" . LOL.

[cpdaman]

hanna #1 is dead

that spin was her LLC- i'm 95% certain

i didn't think a LLC could go right thru a ULL's center

let's see if we get a reformation back toward the convection

http://www.ssd.noaa.gov/goes/flt/t2/loop-vis.html she had a dramatic little "flair" right before her LLC went SW in the high shear

ULL never moved and barely weakened and the LLC never went NW

65 W 21.5N You can see it only on the loop.

I can't find IR2 on that imagery link. They still use the old scheme at the NOAA site for wide areas like the Caribbean: http://www.ssd.noaa.gov/goes/east/carb/loop-ir2.html and you can see it on that in loops although it's pretty small.

with LLC spinning away to never never land what do the pro's think of a center reformation further E ?

[curtadams]

The convective center could only be an MLC if it's independent because it's so new. I don't think the shears are in the right direction for it to be a sheared reflection of the LLC so I'd guess it is indeed a new MLC.

Think it was an eddy she spit out.looks like a blow up already to the east of what you speak of..

I think it was a eddy also... that or she is reforming a new center farther to the east.

i have been following the center /llc like a hawk that's got to be it
curt what exactly do you mean the new convective center MLC is where? back east under convection?

[bahamaswx]

Looks to be the LLC to me. Won't be much development here for at least the next 24hrs or so at this rate. 11pm disco will be interesting.

lordy lordy, phil ferro just mad an absolute mess of trying to explain the ifs and buts of hanna, he needs to just go with nhc track and be done, he shows different tracks and confuses the heck out of the viewers

[ericinmia]

Here is a graphic of JB's Cordinates that I just made up so that the people without any maps/software could take a look at the track. I also overlaid his pressure and wind speed estimates.

I agree that the LLC is just to the right of that eddy where the convection is firing. To me you can see the inflow moving toward the convection. The gray barely visible clouds in this horrible IR2 shot.

thanks eric, it helps explain his track

no way no how IMO the LLC was clearly visible at 64 west a few hours ago moving West fast, it died

what ever is under that blob would be an MLC

and since it's SE of the ULL it will be in a rather poor enviornment unless it moves north or drifts at 2 mph or less

Well we're both wrong I think.



Loop:

IR2 without any crappy enhancement. You can see the LLC remains 65W 21N or there about. This would not be showing an MLC. The LLC moved a bit south in the loop.

If it wasn't at least reasonably close to the NHC track I'd take it with a grain of salt.

Forecast is directly over my house!
