5PM EDT Update
Hurricane Warnings are up now for Sandy Hook, NJ to Sagamore Beach, MA. This includes New York City, Long Island, Long Island Sound, CT, and RI. Martha's Vineyard, and Nantucket.
Tropical storm warnings are up north of Sagamore Beach to the River (north of Boston).
Tropical Storm watches are now up from north of there to Eastport, ME.
Irene has a very large wind field and will be moving relatively slowly through the forecast track (For storms usually in this area), so there will likely be a prolonged period of high winds and very heavy rainfall.
Original Update
Some shear has appeared to the north of Irene (Actually stronger than forecast yesterday) that is impacting Hurricane Irene, and causing it to weaken somewhat. It has a ragged appearance on Satellite this morning, but it is forecast to return to major hurricane status later today and already has hints that this is underway.
The hurricane watch areas from yesterday are now hurricane warnings, and hurricane watches are now up north of Sandy Hook, NJ to the mouth of the Merrimack River (Just north of Boston), including Long Island, Martha's Vineyard, Cape Cod. This means hurricane conditions are possible within 48 hours.
The forecast track has adjusted slightly to account for wobbles overnight, but is still very similar to what it was before. Be aware, the pressure is still low in Irene, and the area of wind that is hurricane force is large in comparison to smaller hurricanes, even if the winds around the core are not is intense. Also a lot of storm surge has been built up by the large wind field.
The wind field of Irene is larger on the eastern (or right of the direction of travel) than the west, but still has a good reach to the west, anywhere that feels the hurricane force winds is likely to lose power across a good deal of area. The good news this morning is that the track shift is slightly to the east, so less inland areas may see impacts, but the outer Banks, and Long Island still are within the eastern area of the storm, as well as Boston. Adjustments back west or east are equally as likely later. Please realize the forecast is not a line, it is a large area of hurricane force winds extend out from the center ~55 miles on the western side, with tropical storm force winds close to 200 miles to the west as well. Irene is currently about the same size or maybe a little larger than Hurricane Ike in 2008, it is likely to be larger than Ike before it reaches the Carolinas.
Please listen to local media and officials, and do not let the wind speed drop fool you, the area of winds is extremely large for a hurricane.
What's happening weather wise or people wise regarding Irene in your area? Let us know here.
See the Forecast Lounge for more speculation on Irene.

Mike has posted a link to the Surge Forecasts above. I'll repost the link by itself here and comment on the Surge Forecasts.
Irene's Current Storm Surge Probabilities
The Probabilities change every 3 to 6 hours. Please check them frequently
Please cycle through the different Surge Height Probabilities when using the Product above.
Anyone on or near the Atlantic Coast from Florida to Maine should heed all Local and Watches and Warnings.
Including Voluntary and MANDATORY EVACUATION notices.
At the present time using Advisory 24 there are several highly hazardous areas. They are as follows, from South to North.
Cape Fear and Onslow Bay,SC
Pamlico Sound, NC
Albemarle Sound,NC
Virginia Beach,VA
Cape Henry,VA
Norfolk,VA
Portsmouth,VA
Newport News,VA
Hampton,VA
Sandy Hook Bay,NJ
Raritan Bay, NJ
Lower Bay,NY
Any location in the vicinity of the above Cities and Bays. Basically any area on the Atlantic Coast from South Carolina northward that faces east or north. These areas allow the wind to pile up seas and surge and will experience Higher Water than other areas.
Especially Bays and Sounds. Including rivers and tributaries to the bays and Sounds.
Surge can, and will move upstream! 's surge moved upstream nearly 18 miles.
Irene is currently forecast to move parallel to the Coast from North Carolina to Maine. This will enable the Sea Level Heights to reach depths as great as 8 feet in some areas.

I believe there is also a new moon this weekend, what type of depth will that add on @ High Tides?

Thanks, I meant to check on that. And you are correct the new Moon is this weekend.
New Moon and Full Moon have a great effect on the tide level. Producing higher tides.

Hurricane Local Statement
Issued by NWS Wakefield, VA edited~danielw
...STORM SURGE AND STORM TIDE...
AS HURRICANE IRENE APPROACHES THE COAST...THERE IS AN INCREASING
CHANCE FOR COMBINED STORM SURGE AND ASTRONOMICAL TIDE WATERS UP
TO 8 FEET ABOVE MEAN SEA LEVEL WITHIN AREAS CLOSER TO THE COAST...
RESULTING IN WORST CASE FLOOD INUNDATION OF 4 TO 8 FEET ABOVE
GROUND LEVEL SOMEWHERE WITHIN THE SURGE ZONE.
THE LOCATIONS MOST LIKELY TO REALIZE THE GREATEST FLOODING
INCLUDE NORFOLK...VIRGINIA BEACH...COROLLA...OCEAN CITY...
WACHAPREAGUE...AND AREAS ADJACENT TO THE CHESAPEAKE BAY. THE MOST
LIKELY PERIOD OF IMPACT WILL BE DURING THE TIME OF HIGH TIDE...
SATURDAY EVENING.
THERE IS A SIGNIFICANT THREAT TO LIFE AND PROPERTY FROM COASTAL
FLOODING. THE CONCERN IS FOR THE CHANCE OF MAJOR COASTAL FLOODING
TO OCCUR IN AREAS WITHIN THE SURGE ZONE...RESULTING IN DAMAGING
AND LIFE-THREATENING FLOODING. IF REALIZED...PEOPLE WITHIN THE
THREATENED AREAS WHO FAIL TO HEED OFFICIAL EVACUATION ORDERS WILL
NEEDLESSLY PLACE THEIR LIVES IN DANGER. THIS IS ESPECIALLY TRUE
FOR THOSE STAYING BEHIND IN VULNERABLE LOCATIONS SUCH AS HOMES
AND BUSINESSES NEAR THE SHORE...AND ONE STORY DWELLINGS IN FLOOD-
PRONE AREAS.
...INLAND FLOODING...
A FLOOD WATCH IS IN EFFECT FOR THE ENTIRE AREA. SEE LATEST
FORECAST FOR LATEST INFORMATION. LISTEN FOR POSSIBLE FLOOD
WARNINGS FOR YOUR LOCATION...AND BE READY TO ACT IF FLOODING
RAINS OCCUR.
8 TO 12 INCHES OF STORM TOTAL RAINFALL IS EXPECTED ACROSS INLAND
SECTIONS OF EASTERN VIRGINIA AND THE LOWER MARYLAND EASTERN
SHORE. LISTEN FOR POSSIBLE FLOOD WARNINGS FOR YOUR LOCATION...AND
BE READY TO ACT IF FLOODING RAINS OCCUR.

Storm surge predictions are the most inaccurately predicted aspects of storms.
Some of my observations:
1. Irene is a fast-moving storm moving (initially) parallel to the coast.
2. These types of storms don't have enough time for a large storm surge as there is not a lot of time for the surge to build up.
3. Once the center is past the water is pulled out.
4. The above does not mean there will not be large wave action, though.
5. Storm surges are larger when a storm is slow-moving.
Storms moving directly into land act differently.
1. Surges are larger on the windy side of the eye - pushing water continuously in the same areas.
2. Obviously, slow moving storms allow the surge more time to build up.
3. Bays, inlets and rivers on the windy side can have much higher surges because the water is forced into a narrowing area.
4. Surges on the non-windy side of the storm do not exist.
5. Water is actually sucked out of bays, inlets and rivers.
I think for the above reasons, storm surge was dropped for the hurricane categories. It is also why SOES never worked. It is also why "little" storms frequently have much greater surges the the "big" ones.

None of this address tides as these are well understood but hard to predict until the storm's arrival is certain.

Danielw,
With the last post I know that was not for us as far north as Manchester, NH but we do have a hurricane watch in effect...
I live on a river... should we prepare to evac when it comes closer to the time period of her hitting i.e. Sat/Sun? Or should we start our hurricane preparation now. We have seen a map released from Weather Channel shows us in extreme... See attached...

You can see the storm surge potential of Irene from the NOAA Irene IKE Scale maps. Ike = Integrated Kinetic Energy (not the hurricane), Right now Irene rates a 5.1 out of 5.99,
It wouldn't be as extreme as the gulf because of the coastline, but I still wouldn't underestimate that much energy.
This is the same even with the current eyewall issues.

How strong do you think the surge will be in NYC? How strong do you think the winds will be in NYC?

Yes... how strong do you predict for my area? I mean people here are panicking. I'm wondering when to go stock up... or move more north of here... I know I'm crazy to say this but... I wanted to experience a hurricane and so now I will be... but I don't want to risk my life either... I'm not panicking, but I want to be prepared... the Mets here say it will be just wind and rain...

StrmTrckrMiami... The Surge analysis for your area has not been run as of Advisory number 25.
The Surge/ / MEOW... whatever you wish to call it is run ahead of the Storm about 36 to 48 hours. Right now it only extends to the Lower Bay,NY on the SW end of Long Island,NY.
This will progress over the day to a point where your area is in the data run and plotted.
Dougyd. You are correct with your observations and analysis. This storm is a bit different than what we are accustomed to in the SE US. The path is parallel to the Coast and Irene has a huge wind field.
Long hours, possibly 24 hours of high winds blowing water into bay, sounds and estuaries will pile up the water. In addition Astronomical High Tides will add to the water pile up.
The water/ surge should slowly recede after Irene's Center passes by.
I have not seen mention of the Jet Streak that is forecast to develop on the NW Quad of Irene in the next few days. This is forecast to aid Irene in maintaining a lower barometric pressure. Which will keep the storm at a steady state longer.
This Jet Streak was analyzed by a NWS office in Pennsylvania yesterday according to the Weather Channel.
Here's a continuously updating Hurricane Local Statement link to your Local NWS Office. Just click on the Office nearest your location.

Thanks Daniel.
Better to be prepared than to not. Living in Florida for the time I did has that drilled in my mind.

I hope that I have answered some of your questions. I can't possibly answer all of them because we really don't know what Irene is or is not capable of.
The wind field is huge. Not as big as , but huge.
Due to the parallel to the Coast track. Some of you along the Atlantic Seaboard will experience winds greater than Tropical Storm force for 18 to 24 hours or more. In addition to Hurricane force winds above 75 mph for a shorter period of time.
The BEST SITE that I have found so far is the NWS FORECAST site.
Put your Zip Code or City, State in the box in the upper left hand corner and GO.

NWS Forecasts update every 3 to 6 hours.

Please go and prepare your home, car and family for an extended period without power.
If nothing happens you can drink the water and eat the food.
Watch your Local TV station, NWS Weather Radio, or AM/ FM Station with Emergency Alert Capability for Bulletins, Watches and Warnings.
The Weather Channel has a lot of really good information right now.
In addition to Winds they are expecting large amounts of rainfall in areas adjacent to the Coasts.
Remember... Hide from the wind. And run from the Water.
Craig Fugate the Director of FEMA is recommending preparations for power outages up to a few weeks.
If you don't lose power you are fortunate, and you may be able to help your neighbor that has no power.
Mike and Ed.
Do these post need to go in the Disaster Forum for reference or should they stay here?

My rule of thumb is that it is fine here until the storm has passed on. At that time, recovery info can go is the Disaster Forum.

In the past few hours Irene has been moving more to the north northwest rather than north - a bit unexpected (but hurricanes are noted for the unexpected). Convection has increased and a visible eye is starting to redevelop. In a few hours, Irene will start to cross the Gulf Stream so some intensification is still possible. If you live in the Carolinas, continue to monitor Irene closely for unanticipated changes.

Thanks, ED. Will Do.
Voluntary and Mandatory Evacuation Orders are being put into Effect Now and this Afternoon in North Carolina, Virginia and States North of the Hurricane.
Please check your local Television, Radio and Local Television Channels for Evacuation Information.
This is a dangerous and possibly Life Threatening situation in some areas.
Storm Surge of up to 8 feet is Forecast.

I just want to say sarcastically, I Love how people here think this is all a game... Floridians know better to be prepared for a Hurricane/TS but here in NH, everyone thinks I am insane going to buy flashlights, and ice bags, and a cooler... and things to be prepared without power for a few days...
