Getting reports of structual damage from possible tornados in Hyde, Beaufort, and Onslow counties. Tornado damage is said to be "significant" in the small town of Belhaven.
Not the way to start out a hurricane. Also, I should mention that Belhaven is often totally flooded by Pamlico Sound during hurricanes, usually several feet of water..

[Eddy Gurge]

I'm here, just trying to stay out of the way. Rarely speak anyway ....but I am watching and worrying because I do have family in Northern Virginia. I'm sure there will be lots of wind even where she is according to what I am seeing on this storms size. Probably no power for a while. She is prepared.

I'm in NOVA as well. I have a generator, and plan on gassing it up for the first time. We lost power for 2 days during Isabel, and water for 4 days due to the main pumps croaking. My only real concern is the easterly winds. Not normal for here. From every other storm we've had, the trees fall to the north or east. We have some big trees behind our house, and they are to our west...

[KatDaddy]

And that why I try to warn everyone I know when it comes to a tropical threat. A passion that never ends. Weather is life.

[capepoint]

Can anyone explain to me why Irene has consistently had some of her highest winds in the SE Quad? It's been bothering me for days.

Also why are the winds not mixing down like usual. The flight level winds are not relected on the surface by the usual reduction formula.

HURRICANE IRENE DISCUSSION NUMBER 27
NWS NATIONAL HURRICANE CENTER MIAMI FL AL092011
1100 PM EDT FRI AUG 26 2011

AIR FORCE AND NOAA HURRICANE HUNTER AIRCRAFT LATE THIS AFTERNOON AND
EARLY EVENING HAVE FOUND SURFACE PRESSURES OF 950-951 MB AND
FLIGHT-LEVEL WINDS RANGING FROM 99 KT TO 108 KT IN THE SOUTHEAST
QUADRANT OF IRENE. HOWEVER...SFMR SURFACE WINDS HAVE BEEN MUCH
LOWER THAN THE STANDARD 90 PERCENT REDUCTION FACTOR TYPICALLY
YIELDS. THIS DISPARITY IS LIKELY DUE TO THE LACK OF SIGNIFICANT
CONVECTION OVER THE SOUTHERN SEMICIRCLE. NOAA DOPPLER RADAR DATA
FROM WILMINGTON AND MOREHEAD CITY HAVE BEEN INDICATING VIGOROUS
CONVECTION REDEVELOPING NORTH AND EAST OF THE RAGGED EYE...WITH
DOPPLER VELOCITIES OF 90 KT OR GREATER AT ALTITUDE ABOVE 15000
FEET. BASED ON THE RADAR DATA AND THE POSSIBILITY THAT THE STRONGER
FLIGHT-LEVEL WINDS COULD EVENTUALLY WORK INTO NORTHEAST QUADRANT OF
IRENE...THE INITIAL INTENSITY IS BEING HELD AT 85 KT.

RADAR AND RECON FIXES INDICATE IRENE HAS MADE THE LONG-FORECAST TURN
TOWARD THE NORTH-NORTHEAST NOW AND IS MOVING AT 020/12 KT. IRENE IS
CAUGHT BETWEEN A BROAD SUBTROPICAL RIDGE TO THE EAST AND AN
APPROACHING SHORTWAVE TROUGH CURRENTLY MOVING EASTWARD OVER THE
GREAT LAKES AND OHIO VALLEY. THE HURRICANE IS EXPECTED TO CONTINUE
MOVING NORTH-NORTHEASTWARD FOR THE NEXT 24 HOURS OR SO AS THE RIDGE
TO THE EAST AMPLIFIES NORTHWARD. THEREAFTER...THE CYCLONE SHOULD
ACCELERATE TO THE NORTHEAST AS IT GETS CAUGHT UP IN DEEP-LAYER
SOUTHWESTERLY FLOW AHEAD OF THE SHORTWAVE TROUGH. THE FORECAST
TRACK HAS ONLY BEEN NUDGED SLIGHTLY EASTWARD OF THE PREVIOUS TRACK
THROUGH 36 HOURS DUE TO THE MORE EASTWARD INITIAL POSITION.
HOWEVER...ALL OF THE MODELS SUGGEST THAT SOME SLIGHT MID-LEVEL
RIDGING WILL OCCUR ACROSS SOUTHERN NEW ENGLAND AND THE MID-ATLANTIC
STATES DURING THE NEXT 12-24 HOURS...WHICH SHOULD ACT TO KEEP IRENE
CLOSE TO THE COASTS OF NEW JERSEY AND THE DELMARVA PENINSULA. THE
TRACK FORECAST LIES DOWN THE MIDDLE OF THE NHC GUIDANCE ENVELOPE
AND IS A BLEND OF THE GFS AND ECMWF MODEL TRACKS.

IRENE IS EXPECTED TO REMAIN OVER SSTS GREATER THAN 28C UNTIL
LANDFALL ALONG THE NORTH CAROLINA OUTER BANKS IN 12-18 HOURS. THIS
SHOULD ALLOW THE CYCLONE TO MAINTAIN ITS CURRENT INTENSITY OR ONLY
WEAKEN SLIGHTLY. AFTER LANDFALL...HOWEVER...LAND INTERACTION...
COOLER WATER...AND GRADUALLY INCREASING SOUTHWESTERLY VERTICAL WIND
SHEAR IS EXPECTED TO INDUCE STEADY WEAKENING. ALTHOUGH A STATIONARY
FRONT CURRENTLY LIES ACROSS SOUTHERN NEW ENGLAND...THIS FEATURE IS
EXPECTED TO LIFT NORTHWARD DUE TO THE VERY LARGE CIRCULATION OF
IRENE. THIS SHOULD DELAY EXTRATROPICAL TRANSITION UNTIL IRENE IS
OVER MAINE OR SOUTHEASTERN CANADA.

Eddy Gurge, watch the changing of the winds and move away from the rooms that could be impacted by fallen trees.

Approximation based on NEXRAD, center of eye now 150 nautical miles nearly due south of Morehead City radar site.

Just doesn't look like it will make Morehead City with the eye based on radar. Looks east. Just east of Raleigh really not pushing much of the banding this far inland. There must be enough mass in a hurricane to act just like a wheel and encounter some friction. Sort kicking itself away from the curved coastline. Have seen so many storms coming in at this angle do the same thing. . Hopefully it will result in less surge into Morehead and spare the barrier islands the RF winds. Good luck stay safe tonite folks.

I mentioned that phenomenon a few days ago in the models thread. Seems like they always come in 20-40 miles north at the last minute.

This may well end-up making landfall over Core Banks just north of Lookout, exact spot that Isabell went in.

I will never forget IKEs waves crashing over the Galveston seawall under clear skies.

I saw that on TV and it was scary.

Can anyone explain to me why Irene has consistently had some of her highest winds in the SE Quad? It's been bothering me for days.

Also why are the winds not mixing down like usual. The flight level winds are not relected on the surface by the usual reduction formula.

there are so many things that are "weird" with this storm, looking over my posts from this storm, it has proven me wrong and wrong and wrong over and over and over on things I thought were simple hurricane facts...all I now know about hurricanes is that I know nothing
