Wsr-88d radar data from morehead city shows what looks like a
classic concentric eyewall formation. With a poorly-defined ring
of convection near the center and a stronger ring 40-50 nm out.
Earlier aircraft data indicates that the strongest winds are
associated with the outer ring. And that there is no wind maximum
associated with the inner ring. The last aircraft fix showed a
pressure of 957 mb. And maximum flight level winds during the
mission were 109 kt. The initial intensity remains 90 kt.
Isabel is moving 325-330 degrees at about 12 kt. A general
northwestward motion should continue for about 24 hr between the
developing mid/upper-level trough over the southeastern united
states and the deep-layer ridge over the northwestern atlantic.
After that. Isabel should turn northward in response to the large
deep-layer trough moving eastward across the northern united
states. All dynamical guidance agrees with this scenario. And the
official forecast track is basically an update of the previous
package.
Little change in strength is forecast before landfall. Although
there is still a slight chance of slight strengthening. After
landfall. Isabel should weaken and gradually become extratropical.
A new aircraft should be arriving at the center shortly.

The first rain band is just East of Raleigh. By the time I go to work it will be starting to rain, and continue for who knows how long.

During Hugo I listened to a Hurricane Hunter talking to McDill on shortwave. It was interesting.
Since then I've only hear a few digital broadcasts.
What little monitoring I've done with this one has produced zip.

Sometimes the raw data is more astonishing than photos themselves, not dissimilar to my golf handicap.
National Data Buoy Center Station FPSN7 located at Frying Pan Shoals, NC reports the following:
5:00 am EDT 0900 GMT on 9/18/2003:
Wind Speed (WSPD): 51 kts
Wind Gust (GST): 57 kts
Atmospheric Pressure (PRES): 29.59 in
Pressure Tendency (PTDY): -0.10 in (falling rapidly)
Air Temperature (ATMP): 72.3 °F

Here's a look at a quieter day sometime not long ago at Frying Pan Shoals, North Carolina:

Wow MFH, I feel it's such a great privilege, an honor and most fortunate that we are able to view some of the very same satellite images as our dear President George W. Bush.

That's because, if you look very closely, those photos behind the president have FR logos in the bottom corners. You heard it here first.

Okay, the water is getting a bit high around this pier. I hope it survives the large waves which appear to be coming in.

Fox showing shots of preparations in DC. President leaving for Camp David (taking Laura and the dogs), workers boarding up windows on the Capitol, etc. Simon Marks is reporting. He will be interesting to hear if he stays in DC for the storm...he is British.

Is it gonna miss Hatteras and skim up the coast?

Of course, that makes perfect sense!
(Wouldn't that be cool if it were true?)
