ATL HANNA: Extratropical - Discussion

[Bane]

storms are definitely on the increase.

[Lowpressure]

jabber, I am still here. She just has not impressed anyone much lately. it seems there is always something going against her.

[Bane]

she's also not much risk to florida anymore.

[cpdaman]

she's also not much risk to florida anymore.

you are right, but that is human nature

also if this was stronger , this thread would be busier for sure

hanna always did seem like there was something going against her

and i don't think the dry air is in a hurry to get away from her

recon still shows a large wind field with a decent swath of 45-50 winds.

and satelite shows the NE bahamas are going to get whacked this evening with winds probably gusting to 60

The National Park Service is closing campgrounds on the southern end of the Cape Hatteras National Seashore at 5PM today in advance of Hanna.

North Carolina is now under a state of emergency. Governor Mike Easley spoke at 2 p.m. in Raleigh about Hanna and the threat from Ike, the Category 4 hurricane that appears to be following in Hanna's footsteps.

new features at the http://www.nhc.noaa.gov/satellite.shtml site under floaters

also appears to me the center may be trying to tighten up as the storm seems to be heading on a 305 or so trajectory for now

cape canaveral may get some squalls tonite since they seem to stick out there and the NW quad appears to extend a good deal from the center

actually looking at radar all of east florida may get in on some squalls with a concentration possible between WPB and canaveral IMO

12Z Euro has Ike going into LA in 10 days....way west.

I just saw some National Guard trucks being moved south from my area.

Drama Queen is a good name for her

[carversteve]

I gotta say..she sure is trying!! Seems like she is trying to wrap up a bit...IMO..and also it looks like the dry air is being cut off a bit..greatly unofficial though!!

They put out over the scan today that all personnel are on stand by for Hurricane Hanna and Hurricane Ike till farther notice. I about lost it when they said Hurricane Ike. But if any one want to make that call they can to check it out. It would be Duplin County Sheriff office.

when you loop this fast you can see her structure is not bad at all

http://www.ssd.noaa.gov/goes/flt/t2/loop-vis.html

she is following forecast points and we should see her turn from about 305 degrees NW now to about NW 315 this evening , then 330 tonite (rounding the ridge periphery) and speeding up

the thing that is concerning to me regarding resident in (esp. coastal Nc/ even sc) is that the forward speed will be near 30 mph when she makes landfall and should she be able to evacuate the dry air that is NOT yet abating IMO (should that dry air fill in w/ moisture she would likely intensify crossing the GS late tonite) i think the best chance to evacuate the dry air will be when she crosses 28 north and gets away from the S shear (that is funneling it in) from the ULL (that is practically on top of her)

http://www.ssd.noaa.gov/goes/flt/t2/loop-wv.html

this leads me to believe this could be a bit more of a hassle than people who woke up and saw her sorry state may assume

[cpdaman]

also i think as she tightens her center in the next two hours it may give the illusion of a more N motion but this is just the edge of the center contracting from the west and the east IM amateur opinion

this will be my last post till later tonite on hanna

but i will say i am concerned that she will intensify in the wee hours when she has the best chance to get the dry air out (away from the ull and it's shear driving it in)

if i were in coastal sc/nc i would prepare for 100 mph wind gusts on friday. especially because on the right front quadrant they say to add the forward speed of the storm and this should be moving 25-30 by fri afternoon.

not saying i think they will occur, but there appears to be *potential for this to occur* and one is always better safe than sorry

she is rather large, so she won't have time to RI, but still don't let your guard down SC/NC residents..........stay safe

[storms in NC]

Thank you cpdaman. that is very nice of you.

For got to say she need to build to the south and South east.

[Lowpressure]

That explosion of convection on the nw quad is somewhat concerning, and unexpected.

guess i lied about last post

but yes from that WV you can see she has a lot of work to do on her South and south east sides

but the visible shows you her structure is there, her LLC is vigorous and when that dry air evacuates (or if it does) we should watch for convection to pop in the S and SE quads sometime after midnite

[GaryOBX]

But it does appear that the tops of those storms are being sheared off. Check it out... http://wwwghcc.msfc.nasa.gov/cgi-bin/ge ... tte=ir.pal

do you all think that ike will follow in her path and head our way here in eastern nc?

I don't know but they have put the sheriff and Law enforcement on standby for Hanna and Ike. They have been telling them all though the day today. So I guess it could.
