Log in Join. It is the end of September, and we have come to the last destination, and the end of this series, as we travel the coastline destroyed by Hurricane Katrina's record storm surge a little over a year ago. This is something that has never been shown on the news or talked about, either in the overall, or in detail. An interesting historical note: Dauphin Island was the first capital of the French colony of Louisiana The capital was moved to Mobile in The surge along the coast in this area ran from about 15 feet in Bayou La Batre, mobile katrina damage almost 12 mobile katrina damage in downtown Mobile, with feet on Dauphin Island.

Louis, MS eastward to the northern reaches of Mobile Bay. The Mobile State Docks measured the highest storm surge value of It is known that the storm surge was as high as feet range in Bayou La Batre, Alabama and was likely closer to 20 feet immediately along the Mississippi-Alabama border.

Many homes were completely engulfed by Katrina's surge in Bayou La Batre. The surge in Mobile Bay led to inundation of downtown Mobile causing the imposition of a dusk-to-dawn curfew. The Mobile State Docks surge value of The exact location and degree of accuracy of the record surge value is unknown, mobile katrina damage. Here a Mapquest image shows the area in more detail.

Dauphin Island is to the south, and Mobile to the north, along the eastern coastline. The small coastal area of Coden and Bayou La Batre is a key center for the shrimping industry in the US, and was completely destroyed. This was poignantly documented in an article mobile katrina damage the Associated Baptist Press only days after Katrina landfalled.

The article had to say, mobile katrina damage, in part:, mobile katrina damage. It's the worst I've seen anywhere," said Joseph Rodriguez, a shrimper and boat builder, who is a native of the area. Katrina's surging waves lifted one of his two shrimp boats, the Integrity, from the bayou and involuntarily dry-docked her at a shipyard, right below the drawbridge in the town's center. Junior Wilkerson, skipper of the Integrity, rode out Katrina on the boat, along with his wife and children, mobile katrina damage.

He fought the plus-mph winds and foot storm surge in a vain effort to keep Integrity from breaking loose from its moorings. Wilkerson said he was never scared during the ordeal.

He's ridden out many hurricanes on his boats, mobile katrina damage, including 's Camille. A tour of mobile katrina damage area Sept. Regarding a boat being the safest place to be in a hurricane The first three images, from a NOAA aerial photo, show the shrimp docks, and the many boats stranded inland. Images courtesy of NOAA. And as we have seen, these aerial images can not convey the sense of the damage that can be seen close up:. See the boats that are sideways or on top of each other, or, mobile katrina damage, the ones where the hull is damaged?

This really isn't the place you want to be in high winds, high waves, mobile katrina damage, and, just under the water, all kinds of large objects that your boat can be dashed against by the waves A boat is the safest place to be? Think about it A hurricane is no time to be in a boat! These two photos are interesting because they show the force of the surge, many miles from where the eye made landfall, and the height of mobile katrina damage surge:.

Flooding engulfed the downtown area of Mobile, and water covered the I causeway over Mobile Bay. One of the most frightening images I've ever seen was, mid-morning, on the day that Katrina hit, this image of the causeway, completely under water:.

The causeway usually sits high above the water:. Here are some images of downtown Mobile during the flooding from Katrina, thanks to Wundergrounder Mobal :. The USGS has a remarkable set of impact studies, including one on Dauphin Islandshowing the dramatic eroding of the western end of the island, which is no more than a sand spit now.

When I was a teenager, we used to go out to the western end mobile katrina damage walk on the dunes, mobile katrina damage, which are no more, mobile katrina damage. Examining overwash deposits was originally used to study tsunami history.

There's a blog entry coming up on this in future. For now I just want to pass on a very interesting piece of information that I heard secondhand, which is that a recent study of overwash deposits indicated that Katrina was on the order of a year storm. We mobile katrina damage already that mobile katrina damage that had been standing all along the northern Gulf Coast since the early s, for around years, were destroyed by the surge.

Someday soon this and other studies mobile katrina damage be published, and more people will become aware of just how uncommon was the extent of Katrina's surge. More amazing facts; what Katrina did to buoys: The National Data Buoy Center keeps a record of significant tropical cyclones and the recorded buoy information on wind and waves, and the report on Katrina contained some information, that while simply and factually stated, was nevertheless extraordinary.

Below is the map of buoys that were within nautical miles of Katrina's path through the North Atlantic and Gulf of Mexico:. First, as maximum significant wave heights started approaching 11 meters at buoyit was capsized. The report notes:. That's a buoy that is about 30 feet wide, that is very bottom-heavy and built to be very stable.

Here's an image of one:. And the highest wave that can usually occur for a given maximum significant wave height, mobile katrina damage about 1. So, for the given max sig wave height before the buoy capsized, which was actually For a good explanation of significant wave height, written in layman's terms, check out this link to the Mariner's Weather Log.

The NDBC site has a more technical explanation. Not surprising, you think? Well, this station's equipment isn't exactly sitting at sea level:. The station at Grand Isle, GDIL1, failed at about the same windspeed, although that failure could also have been due to surge remember, we started this series with Part 1 on Grand Isle?

It recorded a very low pressure reading of But the most remarkable reading came from reliable buoywhich is south of Dauphin Island and east of the mouth of the Mississippi. Here is the section of the NDBC report on buoy Although does not measure maximum wave heights, the maximum wave height may be statistically approximated by 1. At the time of the report, Hurricane Katrina was approximately 73 nautical miles to the west of with maximum sustained winds of miles per hour Public Advisory 26A issued by the National Hurricane Center.

In addition to the foot report, reported seas 12 feet or greater for 47 consecutive hours. We can only speculate about the highest wave heights under the radius of maximum winds RMW in the eastern eyewall, some 50 miles or so to the west.

Mobile katrina damage, by contrast, passed almost over the buoy. Although specific data is not available, oil rigs to the west, in Mississippi Canyon, that were close to the RMW, were severely damaged or destroyed by the huge waves.

Finally, we come to buoy This buoy is usually right outside the Chandeleur Islands and the islands of the Mississippi Sound. However, mobile katrina damage, Katrina set her adrift, and after some hours, she ended up right inside the eye, at the southeastern eyewall as we can tell by the wind and pressure readingsand close to the Waveland and Bay St.

Louis area. The lowest pressure reported was an amazing But mobile katrina damage was more interesting was a maximum significant wave height of about 4. This equates to a highest possible wave of 29 feet from trough to crestor a fifteen foot wave height on top of the storm surge. This wouldn't have been possible without the storm surge, mobile katrina damage. The Mississippi Sound is extremely shallow, except where channels have been dredged for shipping, and would never be able to support wave heights in that range without the additional water depth provided by the surge.

Prior to the arrival of the eyewall, easterly winds would have been able to create waves because of the fetch over the length of the sound, and it is possible that the area of the shoreline comprising the communities of Lakeshore, Clermont Harbor, and Waveland initially received significant waves prior to the surge inundation, unlike the remainder of the south-facing Mississippi coastline which we know also from the Beau Rivage video, which showed at most five-foot breakers hitting the Biloxi shoreline.

Here is an image from a very interesting technical report that documents waves and wave spectra found using the SRA:. The image of waves on the left shows a train of 40 foot waves, which means the maximum wave that could have been encountered in that area would have been around 75 feet max sig wave height of 12m corresponds to a max possible mobile katrina damage height of Were the warnings appropriate? If you have read mobile katrina damage entire series, you are aware that the coastal damage and loss of life from Katrina was primarily from storm surge.

And as Katrina moved towards the northern Gulf Coast in the days before landfall, a small group of people understood the extent of the surge that was not only possible but probable. Was everything done to emphasize and weight the warnings to the general public towards this specific danger?

The information in the different types of warnings that are generated for hurricanes from different levels of the NWS are very specifically defined. The National Hurricane Center advisories do not discuss surge specifics for a coastline; they provide general surge warnings based only on the storm's intensity and the general characteristics of the area where the storm will landfall shallow or steep coastline. This mobile katrina damage be clarified in a moment.

It appears mobile katrina damage there used to be maps of the counties covered by each NWSFO, mobile katrina damage, but those were phased out. I have a link for Slidell, but it is no longer referenced from their home page:, mobile katrina damage.

What can be seen from this map is that Slidell had responsibility for almost all of the coastal areas that were decimated by the surge, for a total of ten different parishes or counties that bordered the Gulf of Mexico or Lake Ponchartrain, covering two different states. And within these ten counties were very different surge mobile katrina damage and very different geographies.

The southern end of Jefferson Parish contained an island, mobile katrina damage, Grand Isle. Plaquemines was completely populated behind ring levees.

Bernard and Orleans parishes had complicated levee and canal systems, mobile katrina damage. The three Mississippi coastal counties had a series of large estuaries and mobile katrina damage on the coast, and, because of the inverted-L of the coastline, and shallow continental shelf, very extremely vulnerable Hancock County in particularto storm surge.

Because of this, there was a need for surge warnings tailored to that parish's or county's situation. This is provided by the Hurricane Local Statement. In other words, this is the county-specific warning information that is available to the public, in any given local area.

And LIX also issues river forecasts for a very large area.
