Cedar key seems to be in the cross hairs for surge. Was reading about the natural sea barrier that fared well during Idelia. But that was only a 6.8 ft surge

I think winds are a big concern for the higher elevations of the southern Apps, even if Helene is not as strong as some of the models sugguest at landfall. I am hopeful that winds will have lost their punch by the time they get to the Northern Piedmont
In theory yes, but at this stage shifts to the right increase the chance for surge to be a significant threat for Eastern Florida. A landfall even as far north as Cedar key would be really bad for the Tampa area.
Thanks! This makes sense, early in the month the SE ridge is more likely to have influence. On models there seems to be a persistent trough off the east coast that is likely to pull the system more to the right.
It seems to me the inhibiting factor for development could be the broad circulation may have trouble tightening. This seems to be why the GFS has a very large hurricane, while the Euro has shown on several runs a broad area of low pressure that never develops despite reasonably favorable conditions.
I-85 is lava. Seems mid-level dry air should keep rain totals in check for the triad. The HRRR depicts this well, with around .5" and 1-2" just to our south.
Top gusts so far: 60 mph Wilmington, 67 mph Wrightsville beach, & a rather suspect looking 77 mph gust at sunny point. Meanwhile, even along the coastline only gusts in the mid 30s south of Bald Head.
Yeah I thought that was pretty well established a couple days ago, that a stronger storm could actually be enhanced by what on paper is shear. You think more of a net neutral impact overall though?
A bit concerning with respect to surge potential especially if this thing comes in a little stronger. Thankfully, for the most part, coastal LA does not build in the flood zones.
Looks like the GFS takes the energy from 90L across Mexico into the Pacific where it becomes a hurricane, making landfall in Mexico before crossing back into the Gulf and developing into a hurricane again.
