As of 200AM EDT, Hurricane Irene was located at 28.7N, 77.3W, 460 miles south-southwest of Cape Hatteras. It was moving north at 14 mph with maximum sustained winds of 115 mph, making it a Category 3 storm on the Saffir-Simpson scale. Irene has a minimum central pressure of 942 mb. Outside of the US, hurricane warnings are still in effect for Grand Bahama and the Abaco islands. In the US, hurricane warnings are in effect for the coast of North Carolina from the Little River inlet north to the Virginia border. Hurricane watches are in effect from the NC/Virginia border north to Sandy Hook, New Jersey. Figure 1 shows the hurricane and tropical storm watches and warnings for Irene. Remember, a hurricane warning means hurricane conditions are expected, and tropical storm force winds will occur within 36 hours. A hurricane watch means that hurricane conditions are possible and tropical storm force winds are expected within 48 hours.

To find out if you need to evacuate, please contact your local emergency management office. They will have the latest information. FEMA has information on preparing for hurricanes. FEMA also has a blog describing their response to Irene.

Satellite Views
Figure 2 shows that Irene is a large storm, with outflow reaching from Florida to North Carolina. Irene's eye is visible in the infrared imagery.

Track Forecast

Irene is forecast to make landfall on the North Carolina coast Saturday afternoon. It will likely be a Category 3 storm, with windspeeds around 115 mph. As Irene moves northwards through the mid-Atlantic region it will weaken considerably. On Sunday, Irene's center will pass through the Tri-State region of New Jersey, New York, and Connecticut, with impacts spread over a wider region due to Irene's size.


Figure 3 Official track forecast of Irene at 11PM EDT, Aug. 25.

Irene and Flooding
Six to ten inches of rain are possible along Irene's track from the Carolinas northward, with 15 inches possible in isolated areas. As a result, flooding is very likely. The Hydrometeorological Prediction Center (HPC) has issued their Significant River Flood Outlook for the next five days shown in figure 4. HPC thinks that river flooding in eastern Pennsylvania and New Jersey is likely, while flooding along the rest of the northeastern US is possible.

Impacts

Tropical storm forces winds will reach the southern North Carolina coast by late Friday, with hurricane force winds arriving Saturday. Within the hurricane warning area in North Carolina, storm surge is expected to be 5-10 feet above ground. This is our storm surge forecast map.

People living on the the east coast of the US from the Carolinas to Cape Cod should closely monitor Irene and be in the process of finishing their hurricane preparations. If you have not started preparing for this storm, start immediately. If an evacuation order is given, please follow it. Irene will be a large storm, impacting areas far from the storm center track.

Dr. Masters will have a new blog entry this morning, and there will be another blog this afternoon. There will be a special online broadcast at 430PM with Shaun Tanner, Tim Roche, Dr. Masters, Angela Fritz and me. Please email any questions you have to broadcast@wunderground.com. We will be taking phone calls at 415-983-2634. I'll be back with another blog entry late tonight.

Thanks for reading,

Dr. Rob Carver

Yes, exactly. I do not really know anyone that goes tanning like that, or uses face bronzer! We do not dress like zebras, and if anything we are very laid back wearing our sundeck shorts, t-shirts, and flip flops. Our hair is pulled up and our makeup... what makeup? If anything I would say yes it could be more true up in the Newark area, but here where I am it just not true. Just goes to show you how good a TV show really is when people believe it!


I went to the Jersey Shore for the first time in July, and not only did I not find ANYONE like those morons on the tv show, but I fell head over heels for Asbury Park - the architecture, the vibe,the pace. Everyone I met there was wonderful, too. I swear, if anything happens to the Stone Pony or the Paramount, I'm going to have to drive up there and volunteer some gutting time.

I agree, and it is not even about prayer on a blog. What I mean is that this is one way we can express our sincere heart felt wishes -- by using the word prayers to truly show our concern. I for one am truly sincere when I offer my prayers to everyone-- that you and yours fairs well.

And not only is not everyone from Jersey like that, but you can find people like that everywhere. Heck, even *Iceland* has terms for them -- skinka and hnakki. Well, not exactly the same phenom, but close enough.

I love how one dumb fake show, sporting actors not even from Seaside NJ nor Italian, have morons worldwide thinking every individual from NJ behaves that way.

I grew up in Monmouth County, NJ, lived there until just this late winter. I've been to Seaside 100s of times. Yes, there are some dopey types that behave in that manner, but they are the minority.

It doesn't take long to figure out where those types congregate and all you do is simply avoid the small patch of beach and the couple of bars they frequent and have made "their own".

I read somewhere that the amount of energy released by an average mature hurricane is 200 times the world's electrical generating capacity.

It doesn't work that way. A precariously balanced boulder at the top of a cliff sure as heck has a lot of potential energy stored, but it only takes a mild push to set it in motion.

Furthermore, we're not talking about *electrical* energy -- just raw energy. It could be as simple as adding a tanker full of biologically-inert dye to the ocean to change the heating patterns from the sun. Want to talk about a ton of energy? Look at what the sun imparts to our world's oceans.

The goal is simply to speed up or slow down the storm by little bits in order to move it into adverse conditions or to catch/miss a trough.

The amount of energy doesn't even cross my mind. In 1900, do you think people could have imagined nuclear power? Probably not. So the last thing I'm going to do is be pretentious about what we can and can't do in the future. I just trust that putting funding into this will produce information that we can use. It may not be fruitful right now or even in the near future, but it may some day. It's better than doing nothing at all. No one knows the future, so we may as well try.
I read somewhere that the amount of energy released by an average mature hurricane is 200 times the world's electrical generating capacity. I am neither an engineer nor a scientist, but I know enough to recognize that it would take an equivalent amount of energy to accomplish what seems to be your goal - to prevent that tropical system from affecting populated landmasses. I bet you could confiscate the wealth over every person on the globe and still be far short of your goal. So, you say "It's better than doing nothing at all," to which I ask "what" is better than doing nothing at all? Who is to fund the "what"? And, to what end?

Kinda hard to quantify real results from prayer though. Rick Perry had his state prayer day back in April to stop the drought and it got exponentially worse...go figure...

Well, the 11am update sure took things down a significant notch:

*No long expected to strengthen at all. Chance of strengthening not mentioned at all, just "little change" in intensity.
*Rather than a 100mph storm off the Jersey coast, we are down to 85mph.

Help, I am starting to let my guard down!!!

Hello, all!

Very, very old lurker--but I have not posted since then grad student Jeff Masters hosted this site at cirrus.umich.edu

Evacuation hint--if you know the back roads of your area, particularly the old state and county highways, use them to evacuate. I was in Ft. Lauderdale/Miami visiting family when Andrew approached. After securing my relatives' houses, I left eight hours before Andrew's landfall to go home to St. Pete. I took Dead Man's Alley (Old 27) north and it was deserted. It was spooky passing the boarded up ghost towns like Clewiston and seeing no other traffic so I headed over to the interstate. Big Mistake! 6 miles an hour bumper to bumper all the way up the coast until Sarasota. Cars were broken down by the side of the road with little hope of rescue.

Good luck to you all! (Native Floridian, now living in Chicagoland)

Outflow looks better. Visible presentation looks better. IR looks much worse.

Looks like dry air is making a difference? WV loop doesn't look that bad. Still not sure what to make of Irene's prospects through landfall.

Every intensity prediction has error -- some storms bomb out unexpectedly. Some weaken more than expected. People complain either way.

In the end, better safe than sorry.

So how long will it be before we can direct hurricanes away from our shores or to dissipate them before they make landfall? I think this should be one of our highest priorities, as opposed to one that's feared. In almost every other endeavour, like forest fires, we strive to control nature. I don't see this as any different. We -should- try to control natures tempests.

Wouldn't you rather see people in school, learning about our world, working, caring for their children? I'm tired of seeing people who lose everything and picking up the broken pieces of their lives to put it all back together. We're wasting time. There's no gain in letting nature have its way in these cases. Misery and suffering should not be seen as virtues. They should be seen as something tragic, that we try to mend, but we should do whatever we can to prevent it in the first place so that lives aren't wrecked. You know, for every person that survives and rebuilds, there's probably another somewhere else that gives up and never recovers from it. Keep that in mind.

I support it. I wish there was more talk about it.
I know there was discussion of this years ago. The thoughts at the time, I think were that Hurricanes and tropical storms provide nessasary moisture movement to this part of the world & messing with that delicate balance wasnt a good Idea.... Resulting in drought etc. Just something I heard long ago. Like lots of things you dont want them BUT, they may be nessesary.

We may begin to see rapid weakening here. Check out the shortwave loop. Look at how the dry air is just erasing this Hurricane from the west now down to the southwest side and is now preceding to its south side.

How so? That's not true.

Surge won't decay. Winds won't come down much more in fact they are more likely to go back up for a spell before reaching the outer banks. This storm still has 24 hours over water at least before it begins to enter the more hostile northern reaches and starts pulling in the dry continental air.

Southern NJ should expect a 100mph hurricane skirting the coast - just as the forecast has called for going on 24+ hours now.

It won't decay much. Winds in storms this size don't decay much. The baroclinic process ramps up as it moves north as well so even if the storm rises in central pressure it is encountering the higher pressure to it's north keeping the PRESSURE GRADIENT intact - keeping the winds up.




He might be talking about the calm before the storm..

White there will still be lots of power outages, downed trees, and local flooding....it seems that the "doomsday scenario" being played in the media since monday may not come true, thankfully.
They have to get people to pay attention, and hype usually does it...but every time the hype doesn't play out, it just makes people more complacent for the next round. fortunately, these storms are rare for the mid-Atlantic/NE...and maybe peolpe will forget the hype the next time "doomsday" is approaching...just in case one of these times the doom does play out.

National Situation Update: Friday, August 26, 2011

Hurricane Irene
As of 5:00 a.m. EDT, August 26, Hurricane Irene was located about 420 miles South-southeast of Cape Hatteras, North Carolina, moving to the North at 14 mph.
Maximum sustained winds remain near 110 mph with higher gusts. Hurricane force winds extend outward 90 miles from the center and tropical storm force winds extend outward up to 290 miles. Irene is now a category 2 hurricane. Some additional strengthening is forecast during the next day or so.
Irene is expected to produce rainfall accumulations of 6 to 120 inches over the East Coast of the U.S.

A Hurricane Warning has been issued for North Carolina-Virginia border to Sandy Hook, NJ, including Delaware Bay and Chesapeake Bay South of Smith Point as well as for the Little River Inlet, NC, northward to Sandy Hook, NJ, including the Pamlico, Albemarle, and Currituck Sounds, Delaware Bay, Chesapeake Bay, South of Smith Point.

A Hurricane Watch has been issued from North of Sandy Hook, NJ, to the mouth of the Merrimack River, including Long Island, Long Island Sound, Block Island, Martha’s Vineyard, and Nantucket.

Significant National Weather
Midwest
Across the Midwest, cooler temperatures are expected behind the cold front. Along and ahead of the front, showers and thunderstorms are possible.  

East 
The northern portion of a strong frontal system over the mid-Atlantic and northeast will move off the Atlantic coast tonight. Moderate to heavy rain will accompany this front, giving the ground a good soaking before Hurricane Irene. The southern portion of the front will deteriorate as Irene approaches the Southeastern U.S. coast early Friday. Heavy rain is expected to start along the Carolina coast at this time and will spread northward into the mid-Atlantic by early Saturday. 

South 
Temperatures will remain hot across the southern U.S. A near stationary boundary across the southern plains and lower Mississippi Valley will continue hot and humid conditions, with the potential to create heat index values near 112 degrees. 

West  
A disturbance over the Pacific Northwest will increase the potential for thunderstorms in this area of the country, however, with sufficient dray air in the region, dry lightning may be possible across the northwest with wind gusts near 20 mph. Thus, creating a threat for the spread of wildfires.
