Hurricane Irene slides toward Bahamas; Strong earthquake rattles eastern U.S.
Hurricane Irene is a category 1 on the Saffir Simpson scale as of 5pm EDT, with maximum sustained winds of 90 mph and a minimum central pressure of 976 mb. Irene is moving to the west-northwest at 9 mph, and continues to impact Hispaniola. Satellite imagery shows a strong rain band continuing to linger over the eastern Dominican Republic on the southeast side of Irene, but wind speeds appear to have decreased substantially in the country since this morning. Winds are gusting to around 50 mph in the Turks and Caicos Islands this afternoon. Wind shear is currently around 10-20 knots in the vicinity, which could delay intensification over the next 48 hours. The strongest winds and thunderstorm activity remain on the northwest side, and the eye that was visible on satellite earlier today has become obscured by new thunderstorm activity near the center of the hurricane. The most recent Hurricane Hunter mission found a minimum central pressure of 978 mb and a large wind field. In their 2pm EDT fix, the National Hurricane Center estimated that tropical storm-force winds extended 180 nautical miles from the center in the northeast quadrant of the hurricane. A NOAA Gulfstream plane (Gonzo) is currently flying Irene and providing dropsonde data, something that was critical in gaining model consensus yesterday. A NOAA P-3 (Kermit) is also on its way to the hurricane to provide dropsonde data, as well.

Track forecast for Hurricane Irene
Models are in better agreement on the track forecast for Irene today, although the GFDL and HWRF continue to be the western outliers. Both of these models are forecasting Irene to make landfall near the Outer Banks of North Carolina on an almost due north track. The rest of the global models continue to slide every so slightly east in their forecast track, with some not making landfall until the hurricane is as far north as Long Island. This afternoon, the ECMWF, which has been performing well this season, forecasts Irene to brush the Outer Banks before sliding up the east coast toward New York. The official track forecast from the National Hurricane Center is similar this afternoon. They're expecting Irene to take a more central track through the Bahamas over the next 48 hours and make contact with the Outer Banks on Saturday afternoon, with a second landfall in New Jersey on Sunday afternoon. Again, it's critical to note that the errors in the track forecast 4 and 5 days out are quite large, and also that the consensus in the models over the past couple of days has been to nudge the track eastward, which can be seen in this track graphic archive.
Intensity forecast for Hurricane Irene
Despite the slight weakening that happened today, Irene is still expected to reach major hurricane status (category 3+) in the next 36 hours as it moves away from the Greater Antilles and into warm "open" water. The models tend to agree on a maximum intensity of category 3, however, the GFDL is the upper outlier, and is suggesting a category 4 on Friday. The intensity forecast from the National Hurricane Center is a wind speed increase to 125 mph (category 3) by Thursday. Irene will surely be a very intense hurricane by the time it nears the Mid-Atlantic.
Magnitude 5.8 earthquake rattles eastern U.S.
A relatively large and shallow earthquake struck the Mid-Atlantic just before 2pm EDT this afternoon, and shaking was felt up and down the east coast and as far west as Ohio. According to the United States Geological Survey (USGS), the epicenter was located 5 miles southwest of Mineral, Virginia, and was 3.7 miles deep—a very shallow earthquake. Buildings were evacuated all over the Mid-Atlantic, including the Pentagon, the White House, and NCEP, but have since been reopened. The National Cathedral in Washington D.C. was apparently significantly damaged in the earthquake. National Mall monuments and memorials have closed for the afternoon. Light aftershocks have been reported by people in the region, and the USGS has reported at least one aftershock (a 2.8 in magnitude).

This earthquake appears to be the strongest to occur in Virginia since May 31, 1897, when a magnitude 6 (approximately) struck Giles County. Reportedly, shaking was felt from Georgia to Pennsylvania and west to Indiana and Kentucky, which is an area that covers approximately 725,000 square miles. It's likely that this quake will have a similar extent when all the reports come in.

No call from them yet?
ah thanks. Had no idea.
i think jeff got bannd for spaming the blog too many times with that chart and the admins called it spam
now back too the storm
they better wake up FAST
All of them are PERMA-BANNED!!! LOL!!!!
I have no idea where in the Bahamas you are. On the current forecast track, all islands except perhaps Abaco would have a shot at hurricane force winds.
I promise you, there was a lot more to it than that. Ref - post 1462.
Moving on. Irene is the issue at hand...Not SketchyW
I totally missed out on this story. I knew he was missing, but had no idea he was banned...Post the chart too much? Lol.
K, thanks Taz.
The high/ridge to the northeast has nosed over a bit more west too-I think in comparing the two images
Yes but just more of the same. They are watching recon data just like everyone else. No need for increase in intensity yet, but like I said if the winds catch up to that drop in pressure and the recon data catches it they will upgrade it for the next advisory. But it's not necessary at this time.
any time
Issuing ultimatums to the Admins will get you the ban hammer. And talking about this particular ban may as well. I'd drop it and move on.
you mean 90L
Nassau, and do you mean Andros? Andros is the most western island (and the largest). haha :)
LMFAO +100 Anyways back to Irene!!

Again, why not be true to the data? Why does that cause a problem..reporting what is actually being seen? An eye at 969 is not cat one
Brett Favre? and Dan Marino? and a Boston Celtics Jersey?
As of 15Z:

As of 21Z:
Current as of 00Z:
Careful brother, speaking about people getting banned can get you banned. And me speaking about people speaking about people getting banned can get me banned. I know it's doublespeak but don't mind the 1984 references, let's just get back to Irene and the threat to all of us. Nothing else to see here.
looks like the north outflow blowing away that trof
90L is looking good. NOAA gave it 30% as of 8 PM
14.8 N and 24.9 W

Yeah, it's cool. Just didn't want you to get banned for posting something relatively innocent.
^^
Its sad to be excommunicated from the church of WU for being funny.
so ture but if you post it too many time on one blog page or blog the admins could call it spam and you can get bannd for spaming the blog wish is a part of the rules on here
now am done talking about this moveing on so i dont get a bannd
then bedtime...
Lol...That's fairly blunt.
Is that what's happening, you can definitely see it though...it's getting pushed back west-IMO
