Category 3 Hurricane Irene tracks northwest through the Bahamas
Hurricane Irene remains a powerful category 3 this afternoon, with maximum sustained winds of 120 mph. Irene is moving northwest through the Bahamas at 12 mph, and its center has cleared the northern edge of Crooked Island. The next islands in the path of Irene are Rum Cay (population 80) and Cat Island (population 1700), which it will encounter later tonight. Irene will track northeast of Long Island (in the Bahamas) over the next 24 hours. George Town has been reporting wind gusts up to around 40 mph this afternoon, and wind speed will likely increase during the next 12 hours as Irene's center passes about 30-40 miles to their northeast. Long Island in the Bahamas will likely see category 1 winds, which begin at 74 mph. Shelters on New Providence and Grand Bahama are open and ready for business, and Grand Bahama International Airport will remain closed until Irene passes.
Irene continues to look well-organized on satellite, especially compared to yesterday afternoon. Since then, intense upward motion, and therefore strong thunderstorm activity, has encompassed the center on all sides, which has led to a well-defined eye. Throughout the morning, Irene's eye wall has shrunk, and a new eye wall could be developing, although it remains unclear at this point. If this is the case, it could lead to some temporary weakening of the hurricane, which would be good for the Bahamas. This afternoon, Irene's hurricane-force winds extend 50 miles from the center, and tropical storm-force winds extend up to 205 miles from the center. Earlier this morning, an Air Force Hurricane Hunter mission investigated Irene and a NOAA Gulfstream (Gonzo) is currently collecting data around the hurricane.

Track forecast for Irene
NOAA has continued dropsonde missions today, scouring the atmosphere for data as far north as the waters off of South Carolina. Every bit of upper-air data that the models can ingest will lead to better forecasts and decreased uncertainty. These missions are an investment that pay off. Irene will track through the central Bahamas today, the northwestern Bahamas on Thursday, and approach the Outer Banks of North Carolina on Friday. Beyond this there is a bit of divergence in the models. Both the GFDL and the HWRF are forecasting a landfall on Long Island, New York, and the ECMWF continues to suggest a landfall even further west than that. NOGAPS is still the eastern outlier, which misses the U.S. all together and makes landfall in Canada. Today the official track forecast from the National Hurricane Center agrees with the GFS forecast through Saturday morning, and then diverges ever so slightly to the west of that through Monday. It has become clear over the past 3 days that everyone on the East Coast from North Carolina to Maine should be prepared to feel impacts from Hurricane Irene.

Intensity forecast for Irene
Irene continues to be embedded in a large envelope of moisture, and wind shear is expected to remain low to moderate, 5 - 20 knots, for the next three days. With water temperatures very warm, 28 - 30°C, these conditions should allow for intensification to a category 4 hurricane (winds of 131 to 155 mph). The only reliable model that's not forecasting this intensification is the GFS, and this is likely due to its relatively course spatial resolution. The National Hurricane Center expects Irene to intensify to a category 4 tomorrow, with a decrease in intensity back to a category 3 on Friday.

IMO storm surge would NOT be the issue in Manhattan however. It's anything but flat. I would "assume" (a dangerous word of couse, ASS-U-ME!)most buildings would handle that if up to codes.
Not at all, i like a feisty debate as much as the next one, but really? wishing harm on people because they are rich? Or because you don't like the city? that's childish.
This is excellent advice. I left early for Gustav and was very glad I did. The models are just that--models--and not reality. A storm can always make an unexpected jog your way. If you have the liberty to follow the [land-version of the] Mariner's 1-2-3 rule and get well out of the way of a storm, do so.
Interesting point

i post some info and am sadey to report there have been some deaths report
Hispaniola
Skirting barely north past Hispaniola, the large storm produced gales and prolonged precipitation in the Dominican Republic, displacing over 31,900 people and leaving at least 85 communities isolated in its wake.[50] Accompanying storm surge affected roughly 200 homes and prompted evacuations along the northern coastlines.[51] The strongest winds also occurred in northern Cibao, where they felled multiple trees and toppled utility poles. Swollen rivers, creeks, and streams caused widespread residential flooding and damage to roads; saturated soil in the region triggered mudslides, causing additional disruptions.[52] Despite its distance, Irene produced extreme rainfall in southern parts of the country that led to many secondary effects. Resultant floods combined with two overflown rivers swept through much of San Cristóbal, causing one bridge to collapse under the rushing waters.[53] The flooding produced at least two drown victims in that area, both later confirmed dead. Elsewhere, another fatality occurred in Cambita Garabitos, and six others were listed as missing.[54] Heavy rainfall also occurred across La Altagracia Province, where one person in Higüey went missing and hundreds were evacuated. Most of the damage in the region occurred due to flooded rivers, with some agricultural losses reported.[55] In all, Irene affected at least 2,292 households according to preliminary reports, with 16 houses rendered beyond repair.[50]
Bahamas
Some islands of the Bahamas experienced extensive damage. On island of Acklins, some homes were destroyed. In addition, winds tore off the roof of a high school on Crooked Island.
Lets break it down more like this and keep it simple and short, if models verify and this comes in at cat2 or the least a cat 1 in the NE....this will be....THE WEAPON OF MASS DESTRUCTION.
And I'm not playing around or Bull$hiting
LOL
Don't worry Gro... I got it too... good for a chuckle.
Still is alarming when you look at those wide SAT loops and look at how tiny we look here in S. FL. (Boca)
I just keep forecast points checked in the box on the loops and hope it just makes one after another for our sake... and misses them east for everybody else.
Ok. Manhattan is kind of tucked away anyway--I'd worry about Long Island, Rhode Island, and Connecticut with the current project path.
Based on the ant piles, right? Proof please :)
Looks that way again. I got nothing out of this but a light show thru the blinds.
OK lol. Give us a full report when it happens ok.

Thanks for the links, Pat.
BTW -My 16-year old decided to leave the NYC area early - picked up a week early and just drove out of there today. He said he tried to tell everyone around him how to prepare and they all just laughed him off, so F*** it. He feels bad, but if they won't listen to someone from Nola, there's nothing he can do but avoid the misery by leaving.
He's a learned man fo sho then.
Best to not be where a Major is headed,, Misery loves company as we know.

Bad omen for the blog
Exactly what I've been thinking

You don't really think the majority of the buildings in Manhattan, the Bronx, Brooklyn and Queens are up to code, do you?

This will be historic...
By the way, I tried to post an image by clicking on image and then putting in the address but it did not take. Any suggestions on how to do this properly? Thanks.
Gee,Torgen. I figured most people knew me by now. You're right, I should throw up a sarcasm flag. I have to throw out a little sarcasm in response to some of the remarks I saw. Got into it last night when I mentioned how dangerous of a situation it could be for the East Coast and New England. Since I was born on Long Island and lived on and off there. It is a great concern for me. I still have many relatives there. What might be coming is not a pretty picture.
It's called TRUST in experts like the NHC. WOW - that's like walking down the shoulder of the road and trusting people don't "swerve" and hit me! Of course, I believe in the NHC a WHOLE LOT MORE! LOL
He's versatile. Watch, next he'll be in NYC.
Hurricane flags blowing during Wilma
Norcross just said - not kidding - his words...
"the odds favor Irene turning north"
Bump
Was that the storm of '44? I wasn't around for it but I've heard about it. I think of AC today and with all those glass buildings on the Boardwalk now and wonder how they'll make out in whatever it is we get this weekend. I guess time will tell...
A North and NW Wind did the Superdomes Roof damage over 8 hours in a Cat 3 Western Eyewall.
And the Windows blown out the Hyatt Regency and other Hi Rises rained down for 10 hours
If staying in a Major Metro Area,,find a hard hat..your gonna need it.
