The pressure has risen all the way up to 930 mb.

And they eye fills in and disappears when doing so looks like Erin starts getting shoved WSW a bit definitely going through a cycle now. I wonder what track implications this may have down the road we shall see.

Possible NC12 overwash. NCDOT may canx some of the ferries too. The bold is my add:

 

Good thing they built that new bridge in salvo.

I KNEW IT

ERIN SHOULD HAVE GONE TO SPECSAVERS

...NOAA AND AIR FORCE HURRICANE HUNTER AIRCRAFT SUGGEST THAT ERIN IS UNDERGOING AN EYEWALL REPLACEMENT CYCLE... 8:00 PM AST Sat Aug 16 Location: 20.0°N 64.6°W Moving: W at 15 mph Min pressure: 934 mb Max sustained: 150 mph

Seems unusually small: 

Hurricane-force winds extend outward up to 30 miles (45 km) from
the center...

-- NHC 8pm advisory

Islands continuing to get lashed by the outer bands of Erin

Gfs is even closer now.....

Euro ai still very consistent still.

Nhc track is to far east now

Of note looks like all the hurricane models took a big shift west as well

Great thing about being in radar range is you can track the wobbles

sharp wobble southwest.

Observing radar the past 12 hours has been fascinating. Erin's small inner eyewall refuses to die. Its ring will weaken for a time, then come back with intense DBZ echoes. Yet, the outer concentric band remains but doesn't appear to be intensifying enough to allow the inner eyewall to finally choke off and collapse. So Erin appears to be in a long-duration replacement cycle. Some mentioning of shear might be the culprit. However, I don't agree with that assessment because these are relatively low values that shouldn't be enough to disrupt the process. We've seen these cycles complete with even moderate shear. I suspect the concentric band is just taking a long time to reach an intensity that would create enough subsidence to do the deed. These processes remain highly unpredictable, statistically, and quite chaotic, so it's really difficult to forecast how an EWRC will unfold with regard to time. Eventually, the outer band should strengthen enough to finish the cycle. But for now, it seems Erin is in a steady state, and the earlier abrupt rise in pressure has stabilized.

Erin's RMI should continue to expand, and the hurricane should become quite large. Eventually, we should get a larger eye, and it may clear out. Though I don't think Erin will be able to reintensify enough to regain its peak intensity from Saturday. Especially considering that southwesterly shear should increase by Monday enough to keep it in check. It should still remain a Category 3 or 4 as it increases in size, however.

OBX keep an eye on this one.

These wobbles might put them in play if she turns too wide
