I just heard Watkins on the phone with a CNN producer.. Looks like Sudduth may have an interview with Wolf Blitzer on CNN during the 6pm hour

[MBryant]

Pretty thorough NE jog on radar. She wants to get back over water.

I may be wrong, but I seem to notice a minor easterly jog as eyes interact with a land mass. It doesn't usually amount to a lot at two or three hour intervals, but it seems somewhat consistent.

I got roughly 40 degrees and 15 miles in a little less than an hour...roughly.

Irene is re-doing the exterior of my house. Apparently, she doesn't like rain gutters because she just ripped them off.

Mark Sudduth is currently south of Nags Head, NC...his live shot shows the water of Roanoke Sound being pushed away from the shore...it's all mud as of right now.

He's got some great footage ongoing.

[wxman57]

Good MDL website with a nice clickable map for tide/surge info across the northeast:

http://www.nws.noaa.gov/mdl/etsurge/ind ... &region=ne

Surge values may be a bit low in spots, compared to NHC forecasts, which, by the way, are available here:
ftp://ftp.nhc.noaa.gov/surge/Latest/

There are static and animated deterministic Irene surge forecasts on that page.

[Jevo]

Watching hurricanetrack right now... they are parked on Pamlico sound and the water is gone.. the wind is pushing it all to the Western bank.. its all mud

Surge at Sewell's Point, VA (southern Chesapeake Bay)



This is pretty concerning, because they'er in for quite a few more hours of onshore wind and the tide is now on the rise.

[brunota2003]

Mark just measured a 65 mph gust, winds sustained around 55 mph.

[SNOW_JOKE]

You guys watching this? http://www.hurricanetrack.com/ one of the Sound's in N.Carolina completely exposed as the winds driving the ocean water completely back out to sea.

[Dave]

[72Packer]

Just got a report from mother-in-law in Washington,NC. She has lost part of her pier, neighbors lost all on both sides except some pilings. Streets are flooded and no way out at present till wind swings to west and pushes w
ater out of Pamlico river.

That is pretty cool stuff. I wish they'd go to the other side and show where all that water went.
