If the 3k Nam is right then you will be right side of the center so figure you good for gust to near cane strength, the hi res models dont really have a lot of tornado threat in them right now...

Thats good news so far. Thank you
 
No wonder they got started at 11, this suggest a large and organized low level wind field with a closed surface low

GFS now the east outlier lol....it has a big jump so it moves the center where as the other models seem to keep the one forming this morning

lets not forget this, the last 12-18 hrs before landfall going to be over some very warm water, it really comes down to shear which looks like its going to be around to some degree the entire time, though it does weaken quite a bit Friday afternoon into night....so if it can hold on to a well defined LLC, and then the lower shear period matches up with the best water temps its easy to see why the models are gungho with strengthening it into the 980's...

I guess we Georga weenies will just have to live with the cool, breezy conditions on the backside while you Carolina weenies crank up the generators.

Looks to be a decent blow for coastal areas and just inland with fully leafed-out trees.

It's messy. As long as have this convection shaped like a 7 to the north, northeast, east of the center the tendency is going to be for the llc to chase the convection or centers to spin up and down with convective bursts. Then you add in new convective bursts closer to the LLC as it tries to get some tropical characteristics and you get a bouncy track like the 3k. If you build the convection near the center and start to stack this it'll likely lean left. If it stays void of convection and sheared it'll lean east. I'd personally go with the nhc forecast but any random convective bursts overnight or tomorrow that can wrap the actual center can quickly change this to a up 40 to 95 track vs the sounds
 
The short timing on this kinda reminds me a bit of Isaias in 2020. I was at Oak Island during that one and 18 hours before it hit, most people on island had no idea that there could be a hurricane coming as most forecast kept it a tropical storm. We were to the east of the where landfall occurred between Ocean Isle and Holden Beach and the storm hit as it was still strengthening and at a perpendicular angle causing a 7ft storm surge.
