Flood walls hold on the Susquehanna
Posted by: Dr. Jeff Masters, 29. kesäkuuta 2006 klo 12:09 (GMT) +0
The Army Corps of Engineers is breathing a sigh of relief today. After the failure of New Orleans' levees during Hurricane Katrina revealed that the Army Corps had failed to properly construct those structures, they must have been very anxiously watching the flood walls restraining the rampaging Susquehanna River in Wilkes-Barre, PA yesterday. The new flood walls, built in response to the record flooding from Hurricane Agnes in 1972, were built 3-5 feet higher at a cost of $200 million. The new walls took 20 years to build, and were completed in 2003. Do to the uncertainty of how long the new walls could hold back such a large volume of water, over 100,000 people were evacuated yesterday from the Susquehanna's flood plain. The Susquehanna crested late Wednesday at 34.4 feet, just six feet below the tops of the new flood walls, and 16 feet above flood stage. The river is slowly declining, and was at 32 feet this morning at 4 am EDT.


Figure 1. Measured rainfall from the week's rains. Tropical moisture streaming north along a stationary trough of low pressure triggered rains as heavy as 3 inches per hour in the mountains of Pennsylvania.

Hurricane Agnes of June 1972 did $8.6 billion in damage to Pennsylvania and surrounding areas. Agnes at the time was the costliest hurricane in history, a distinction it held for 20 years--when Hurricane Andrew came along. Thanks to the recent spate of intense hurricanes hitting the U.S., Agnes has fallen to number nine on the list of costliest hurricanes of all time. Six of the nine costliest hurricanes of all time occurred in the past two years!

Tropical wave in the Caribbean
A strong tropical wave moved through the Windward Islands yesterday, bringing heavy rain and wind gusts up to 36 mph. Strong upper-level winds from the west severely disrupted the wave overnight. This wind shear of 20-30 knots is expected to continue, and no development is likely today. The wave is expected to bring thunderstorms and gusty winds to Puerto Rico and Hispanolia as it moves west-northwest at 20 mph. The wave could get more organized once it gets closer to the U.S., if it can find an area of lower wind shear to take advantage of. The prospects of this happening are low, as most of the ocean areas surrounding the U.S. are expected to have high wind shear over the coming week. None of the computer models develop this wave, and there is really nothing anywhere in the Atlantic that looks to be of concern over the next few days.

Thanks to all of you who tuned into my "Tropical Round Table" interview last night on http://radio.nhcwx.com/. I'll be summarizing much of what I said in tomorrow's blog. In particular, I'll focus on how different the large-scale atmospheric patterns for this year's hurricane season are compared to last year's season. This year will not be a repeat of 2005!

Even a tropical disturbance, given the right conditions, can wreck havoc when it comes to rainfall.

anyone know what the disturbance in the southern gulf looks like today?

This morning msnbc.com had an image of someone looking over the new floodwall with the caption, "Levees Safe."

Dr. Masters said..."This year will not be a repeat of 2005!"....

I would tend to agree. By July 4th of last year we had Cindy and Dennis cranking up. We've only had the A storm so far in 2006 and the prospects for anything else in the near term aren't great.

Compared to 2005...this year, so far, has been a dud.

I hope its not like last year..2004 was just as bad or worse for some for different reasons though..so a slow start doesn't mean it won't be an active season.I doubt we will ever see another year like last year..That was wild.

I agree it could crank up during the peak of the season. One word describes this year so far...SHEAR!

I'll admit I didn't get a chance to catch the Tropical Round Table, if someone did catch the episode....what did Dr. Masters say about the overall pattern this season and how it does differ from 2005...I know he mentioned that he would blog about it, but would be curious to see a preview...lol.

Wow,

I didn't know that area was flooded as recently as 1972. I guess if we use the same thought process that the majority of the country used regarding New Orleans and its flooding, then those folks should have known it would flood and moved to higher ground. And according the Mr. Hastert, our taxpayer money should not go the helping these people.

Keep in mind that New Orleans had not flooded since 1968 or 1969 prior to katrina and yes, I am being sarcastic about the events in PA. I feel for every one of the people caught up in this disaster.

In my real lifeI own a business and I travel throughout New Orleans in a sales capacity and talk to people from all walks of life and economic ranges and I have learned the real tragedy of Katrina.....it was never reported on the news...

The real tragedy of katrina was that the majority of people who did not leave New Orleans when the evacuation was ordered did not leave on their own free will. They owned cars, and had places to go, but instead of leaving, they went to areas that they thought would be safe from the ravages of the storm. Many of these people had a plan in place to evacuate to the Superdome, no matter what anyone said, and just as many evacuated to the housing projects in New Orleans to be with family since they were sure the feds would take care of them on federal property. By the time they realized the levees had failed and the water was rising, they were stuck due to water in the roads and the flooding of their vehicles and then walked to the convention center and superdome.

The real tragedy of the storm was put in place in the 1960's by politicians who tought these citizens that they would always have a place to run to in order to be cared for. These citizens were denied the knowledge of self preservation and self determination by a welfare system that took care of them at every turn, from medicine and the "charity hospital system", to shelter and the "HUD" housing buildings throughout the city(remember the CNN footage of the kids on the roof holding the banner pleading for help, that, was a housing project), to transportation and free passes for the RTA busses and street cars. 3 and 4 generations of residents have leased these same HUD housing units until katrina, and now, they are forced to start again and find real housing and transportation and medical care. Kowing the horrors of this event as intimately as I do since I am a life long resident of the New Orleans area I wonder, is this devastation of the welfare and HUD systems is a good thing or a bad thing?

"You would never hear Dr. Grey make such a bold statement."

Yet he issues a statement that gives the number of storms, which is less than 2005.
21. sayhuh 29. kesäkuuta 2006 klo 14:25 (GMT)    
All,

I have a question...as thermal dynamics of the earth seek to move energy from the equator to the poles, thus creating a thermal gradient in the upper latitudes [aka jetstream], is it plausible to corelate the activity of a given hurricane season to the subsequent following seasons based on where/how the jetstream may set up based on that heat exchange? I am wondering if this cycle could have a predictive quality to determining Winter/Spring cycles based on the preceding hurricane season.

Food for thought..I encourage feedback, as I am not an expert. It seems cogent?

there seemed to be a stationary parallel to the Appalachian Mountains which seemed to serve as a furrow for gads of moisture to travel along north. how historically common is the setup?

3807 said..." Are you the kind of sports fan that gives up on his football team after it starts the season with 2 losses?"....

In this case, no storms is great! I hope none develop the rest of the season. Your statement above makes it sound like we're frustrated there has only been 1 named storm. I'm glad!

May it continue...which it won't.

3807, you are missing my point. You said...

"You would never hear Dr. Grey make such a bold statement."

My response to which is.. he DID say 2006 was not going to be a repeat. He just said it with numbers. His numbers for 2006 are a long way off from what happened in 2005.

Emotion has nothing to do with it. I simply said that Dr. Greys "numbers" point to the fact that he doesn't believe this will be a season like 2005. How is this NOT true? How is this "emotional"?

And where did Dr. Masters say his thoughts were based on June alone? In his blog somewhere?

I have a question for you guys...Is there anywhere on wunderground.com you can click to get the disturbance models that Dr. Jeff Masters puts on his blog?? Like the one above? Just wondering, thanks for the help.

Dr Masters said yesterday he did not know a lot about the ITZ, so we all are learning as we go along regarding Tropical Cyclones. I am in NE Florida and I'd like to be in a weak Cat1 Hurricane please.

WSI.........Whats up with you copying everyones comments? Did you learn that in college? Everytime I come on here, your on here posting copies of their remarks. Believe me, i've seen all kinds of know-it-alls on here. No one knows everything. This blog is suppose to be a fun place for people to go chat about the weather, not about you correcting everyone.

There are ways to discuss without arguing. Points can me made without arguing.

latest NAM model run 12Z has the caribbean wave headed for south Florida in 84 hours as a 1016 mb low..not much, but it's the only game in town.

Looks like it continues into the gulf and helps enhance rain along the gulf states.

Disney, the east coast has been dominated by a trough for most of June. This pattern looks to finally take a break hopefully next week as the Bermuda ridge bulds westward.

That strengthening Bermuda ridge may keep the Caribbean wave headed west..northwest.

We never all agree with everything that someone says.......Its ok to debate but when thats all you do then your going a little over board. I see things on here all the time that i think are wrong but i dont keep pointing them out to people. All im saying is it turns people off and makes them leave and i dont like that. I want this site to have a good reputation, not one that people are afraid to speak their opinions in fear that they will confronted for being wrong. Heck, I havent met a perfect weatherman yet........

if your afraid of being corrected you have no place here. this is a scientific discussion, its not always nice and happy. plus, whats so bad about being corrected? its the only way to learn.
