ATL: ISAAC - Post-Tropical - Discussion

[BigEasy]

I think you're onto something. The outlined area some are looking at as LAND is often underwater and surely is with hurricane tides. This along with coastal erosion makes those outlines very suspect.

That is true. Once a storm approaches, all of that area becomes completely under water, from the tidal surge. So basically, and not counting the very tiny strip of hard land, which is the river levee on both sides of the Mississippi, all of SELA is now under water for the most part, except the areas abut 20 miles straight south from New Orleans northward.

Do we know that the back levees in Plaquemines have been breached, or are you saying there's so little land due to decades of erosion that it's mostly water?

Errosion. Coastal restoration is the long term answer, but with the cost now to have a plan forward, is not feasible. It should have been addresed over the years, but I digress.

im heading down highway 23 se of NOLA towards the peninsula hopefully going to make into the eye later.

Take care Aric, get some great footage but keep out of harms way.

close up view wow at the tower going up at the center. http://www.texasstormchasers.com/wp-con ... 8/2229.jpg

Awesome!!

latest saved radar frame. The NOAA plane identified the center directly over that small area of convection. Entire eyewall almost in view.

If it had done this 24 hours ago, like a lot of us expected, New Orleans would have been in trouble.


Looks like it finally broke the threshold.

Aric you may want to check on HWY 23. I think I heard Nungesser(parish president) say they were closing 23 from about Myrtle Grove or Jesuit Bend on down. And according to the Entergy power outage map, power is out in the parish from about the Conoco refinery on down to Venice.

South Plaq parish, extreme south, borders the Grand Terre chain to the marsh nearvVenice. It has been erodeed so profoundly that each and every year you need to figure out what is still there, and what is not. We fish that area. The amount of land loss is shocking.

You will be in the center, but will be cut off from heading down hwy 23, because they have it closed about 5 miles down from the city. iF you have intentions of going further south on 23, you will be dissapointed. It floods ungodly when someone takes a.....

You be careful there, bro!

Yes, road closed at Walker road in Oakville by Corp. I live at 41 mile marker in Pointe Celeste (Plaquemines parish). Winds are really blowing .

That hot tower is holding up really well

Looks like it is feeding off the pool of 4000 CAPE to the south of the LLC

Feal badly for my fellow Louisianans down there; you guys are going to get slammed again. Take care.

I've heard nothing on local NOLA TV of any Plaquemines back levees being breached or even topped. I'm sure the post was simply referring to the narrow strip between the back levee and the river levee. I did an offshore fishing trip out of Venice earlier this month, and there are many places along Hwy 23 where you can see both levees a matter of blocks from the highway on either side. But I'm certain surge is already covering the entirety of the marsh outside all hurricane protection levees both east and west of the Mississippi River.

Look at the SE quadrant inflow on visible. It's feeding right over the top of the Loop Current.

Yes, deputies were ordered they were not to go below Port Sulphur until further notice. Son is in Buras (fireman) Its getting really rough.

Can you imagine if this was 10 or 15 mb deeper?

[Countrygirl911]

Weather channel just said it is strenthening how much more can the winds get up to before land fall
