Irene's Eye is clearly visible in this photo taken 22 minutes ago. It almost appears to be an annular Eye.

Is there any particular reason for that?

A hurricane with an Annular Eye is normally a well developed, steady state hurricane. I don't classify Irene as well developed.
But the smooth round circular Eye is nearly annular.
Similar to looking into a piece of pipe, or the hole in a doughnut.
From Wikipedia:
An annular hurricane, also known as a truck tire or doughnut hurricane,[1] is a tropical cyclone in the Atlantic or Eastern Pacific Oceans that features a large, symmetric eye surrounded by a thick ring of intense convection. This type of storm is not prone to the fluctuations in intensity associated with eyewall replacement cycles, unlike typical intense tropical cyclones. Annular hurricanes also tend to persist, even when encountering environmental conditions which easily dissipate most other hurricanes. Forecasters have difficulty predicting the behavior of annular hurricanes; they are a recently recognized phenomenon, and as such, little is known about their tendencies. Because of this, they can be more dangerous than typical hurricanes.

Isabel, another "I" storm with a similar forecasted landfall, was also annular.

Pressure is down to 974 on latest pass through the center. Annular Hurricanes are extremely rare, btw Some other examples where Luis (95), and also as it was crossing FL.

That's what threw me off when i first saw the Eye. I've enhanced it locally and I still can't determine if it's annular or not.
The ocean can be seen in my enhancement. But the angle is a bit off.
I seriously doubt Irene is annular at this point due to her fluctuations.

There was just a 5.8 mag earthquake northwest of Richmond Virginia.
Right now the track of Irene is on the 's track. I don't think it's going to change much if at all over the next few days.
BTW, Irene is nowhere near annular, the entire system needs to be nearly perfectly round for that.

Looks like I stirred up something. This link should help... somewhat.

We felt the shake here in Wilmington, NC - not enough to worry about with Irene to add earthquakes on top of it.

Getting reports from internet connections of people feeling it in WV, SC, NC, NY, the entire area... that's just what they would need, try to deal with the aftermath of a quake with a Hurricane on the way!!!

Yeah - we had to evacuate my building - just got back in a little bit ago.
I've been through Cat 4 storms, but being on the 3rd floor when an earthquake hits? You start wondering if you shouldn't head down the stairs

Latest Recon vortex has a closed eye again, with pressure down to 976, it's getting far enough away from Hispaniola it may be attempting another strengthening spurt. Winds are down though because of land interaction so it may actually go back to Cat 1 for a bit.

Daniel, I took a look at the high res Modis pass from a couple hours ago and the storm didn't look annular to me. Newer GEO passes are looking even worse.
OT: Felt the earthquake quite well. Slow shaking, then more violent shaking. Nothing fell, though.

The track has shifted east yet again... at this rate its going to miss NC and make landfall in NJ. Down a few mph making it a Cat 1 temporarily.
Grace Bay (T&C Islands) is reporting winds out of the NE at 35 gusting to 60 mph, pressure down 0.3 inches from early this AM. The center of Irene is still approximately 80 miles away, but by 2AM this location will in the thick of things with storm being only 30-40 miles away (just to SW) if the track holds.

most models are east of the track even more and most of them now show no US hit.
