Isaac slamming Gulf Coast with damaging floods, tornadoes

Slow-moving Tropical Storm Isaac continues to hammer coastal Louisiana, Mississippi, Alabama, and Florida's Panhandle with tornadoes, torrential rains, high winds, and a damaging storm surge. Over the past 24 hours, destructive tornadoes have touched down in Biloxi and Pascagoula, Mississippi, and one person was killed by a tree falling on a car in Pearl River County, Mississippi. A major flood event is occurring in Slidell, Louisiana, where Isaac's storm surge filled Bayou Bonfouca and the W-14 Canal, inundating portions of the city with 1 - 5 feet of water. While Isaac is now a weakening minimal-strength tropical storm, it is still a potent rainmaker, and will cause damaging floods all along its path for the next three days. Major river flooding is occurring or is about to occur on a number of rivers in the landfall area. In north central Tangipahoa Parish in southeast Louisiana and southwestern Pike County in southern Mississippi, a mandatory evacuation has been ordered for all low-lying areas and along the Tangipahoa River, due to the potential failure of the Lake Tangipahoa dam. Audubon Park in New Orleans, recorded 11.19" of rain as of 7 pm Wednesday night. An earlier amount of 19" was found to be erroneous, and this is not a 24-hour precipitation record for the city. According to wunderground's weather historian, Christopher C. Burt, New Orleans' greatest 24-hour rainfall on record is 14.01" on July 24 - 25, 1933. The Louisiana official state 24-hour record is 22.00" on Aug. 29, 1962 at Hakberry, although U.S. Army Corps of Engineers `Storm Studies' mentions a 23.80" falling in a 24-hour period at Millers Island during a TS on Aug 7-8, 1940. Storm total was 37.50" over a 60-hour period there during that event.

A few other rainfall totals from Isaac, through 11 am EDT on Thursday:

15.02" Marion, MS
10.09" Hattiesburg, MS
10.15" Gulfport, MS
9.80" Slidell, LA
9.74" Biloxi, MS
8.52" Mobile, AL
5.57" Baton Rouge, LA

Isaac's winds and storm surge overcomes the seawall and floods South Beach Boulevard in Waveland, Miss., Wednesday, Aug. 29, 2012, the seventh anniversary of Hurricane Katrina hitting the Gulf Coast.

Isaac's storm surge winds down
Storm surge levels along the coast of Mississippi and surrounding areas are gradually receding, and the surge has finally fallen below 5' at Waveland, which experienced a storm surge in excess of 5' for 36 hours. Isaac's storm surge levels were characteristic of a Category 2 hurricane, and lasted for an exceptionally long period of time. Waveland, Mississippi experienced a peak surge of 8' and peak storm tide of 9' (surge plus the natural high tide), which beat the levels that occurred during Category 2 Hurricane Gustav of 2008 (7' of storm tide.) The peak 11.06' storm surge at Shell Beach, which is in Lake Borgne, 30 miles southeast of New Orleans, exceeded the 9.5' surge recorded there during Gustav. According to an article in nola.com, Isaac pushed a storm surge of 13.6' into Lake Borgne, on the east side of New Orleans. This is not far from the 15.5' storm surge Hurricane Katrina brought to the location. It is quite possible that Isaac's storm surge might have breached levees of the east side of New Orleans, flooding areas inhabited by tens of thousands of people, had the Army Corps of Engineers not completed their $14.5 billion upgrade to the New Orleans flood defenses this year. I estimate that storm surge damage from Isaac will exceed $2 billion. Isaac has likely caused $2.5 billion in insured damage not related to flooding, insurance firm Eqecat estimated yesterday. Here were some of the peak storm surge values that were recorded at NOAA tide gauges during Isaac:

11.1' Shell Beach, LA
8.0' Waveland, MS
3.5' Pensacola, FL
4.6' Pascagoula, MS
3.8' Mobile, AL


Figure 2. A TRMM satellite 3-D view of rainfall on Aug. 28 showed a few very powerful thunderstorms near Isaac's eye were reaching heights of almost 17 km (10.6 miles.) Intense bands of rain around Isaac were occasionally dropping rain at a rate of over 2.75 inches per hour. Image credit: SSAI/NASA, Hal Pierce.

Isaac's storm surge on the Mississippi River
A storm surge estimated at 12' moved up the Mississippi in Plaquemines Parish near Port Sulphur, LA, near 8:30 pm EDT Tuesday, causing overtopping of the levees and flooding of homes in the mandatory evacuation areas behind the levees. These levees were not part of the $14.5 billion levee upgrade New Orleans got after Hurricane Katrina, and were not rated to Category 3 hurricane strength, like the levees protecting New Orleans are. Since salt water is more dense than fresh water, the surge travelled along the bottom of the river, with the fresh water flow of the river lying on top. The surge continued upriver, and before reaching New Orleans, encountered an underwater barrier in Plaquemines Parish. This barrier was constructed by the Army Corps of Engineers beginning on August 15, in order to keep salt water from moving upstream and contaminating drinking water for Plaquemines Parish and New Orleans. Salt water had made it 90 miles upriver to the outskirts of New Orleans, due to the low flow rate of the river (which had dropped 7' below average in height due to the drought of 2012.) According to a spokesperson for the National Weather Service River Forecast Office, this barrier was probably able to completely block the flow of salt water upriver due to Isaac's storm surge, and no salt water made it as far as New Orleans. However, the massive intrusion of ocean water into the river channel caused the mighty Mississippi's fresh water flow to back up for hundreds of miles. Water levels were elevated by 10' in New Orleans (103 miles upstream from the mouth of the Mississippi), 8' in Baton Rouge (228 miles upstream), and 1.4' at Knox Landing, an amazing 314 miles upstream.

Hurricane Kirk in the Central Atlantic
Hurricane Kirk intensified into a 75 mph Category 1 hurricane this morning, becoming the busy 2012 Atlantic hurricane season's fifth hurricane. With the season's mid-point of September 10 still almost 2 weeks away, we've already had 12 named storms and 5 hurricanes, which is close to what an entire season experiences in an average year (11 named storms and 6 hurricanes.) Kirk should stay well out to sea and not trouble any land areas.

Tropical Storm Leslie forms in the Central Atlantic
Tropical Storm Leslie has formed in the Central Atlantic. Leslie's formation on August 30 puts 2012 in 2nd place for earliest formation date of the season's 12th storm. Only 1995 had an earlier formation date of the season's 12th storm. With records dating back to 1851, this year is only the second time 8 total storms have formed in August. The other year was 2004, when the first storm of the season formed on August 1 (Alex), and the 8th storm (Hermine)
formed on August 29th. Leslie is organizing quickly, and appears destined to become a hurricane before the week is out. Fortunately, Hurricane Kirk is weakening the ridge of high pressure to the north of Leslie, and Leslie is expected to turn to the northwest and miss the Lesser Antilles Islands. In the long term, it remains unclear if Leslie will follow Kirk and fully recurve out to sea. The latest 2 runs of the GFS model have predicted that Leslie will recurve out to sea and not threaten any land areas, but the latest 2 runs of the ECMWF model have predicted that the trough of low pressure pulling Kirk to the northeast will not be strong enough to recurve Leslie out to sea. Instead, the ECMWF predicts that a ridge of high pressure will build in early next week, forcing Leslie more to the northwest, making the storm a potential threat to Bermuda, then to the Northeast U.S. and Canada in 8 - 11 days.

Seems like Leslie is another victim of the fast trade winds east of the Antilles. CIMSS analysis shows the mid level circulations somewhat S of the main low level spin. This should put a curb in major strengthening for a while.

I agree with much that was said but I still think people lose site as the difference in the size of storms.I have been through Camille (200+) mile per hour wind gusts, Elana, Georges, Fredrick, Katrina and now Issac, all living on the coast. As strong as Camille was it came and went. To have a storm batter your coastline for 30-40 hours and a 10-15 foot storm surge might very well do as much damage.I hate to see what it is going to cost to replace our beach in Mississippi, it look pretty sad today.


That is quite a hall of fame for famous storms!! Poor ol Mississippi sure takes her share plus!! I remember driving down I-10 about a month after Katrina headed to NOLA...What little I could see of Biloxi looked like it had been nuked!! The French Quarter was absolutely unchanged. Speaking of Camille....one of my favorite books starts out..."Camille had either been the worlds most powerful hurricane.....or the largest Tornado in history"

I think Leslie will begin to go WNW and in a couple days NW and then NNW. The islands should prepare as Leslie should be a hurricane by then and anything could happen.

I'm wondering if the remnants of Isaac will eventually reemerge into the Atlantic, off the Carolinas, and redevelop into something. The models do have his remnants heading in that direction. Just a thought, anything is possible as we all know too well.


Ivan the terrible did that a few years back. Even looped back into the GOMEX but failed to reform into anything significant...this year....anything is possible!!

LOL well yeah, is possible. Obvs, if he did get to that area...and the conditions were ripe for it...it could happen. Could have happened with the bits that tore off him and caused havoc in FL. Being what an odd sod he was...I reckon it'd be a possibility with him...just to be a pain!

There are three things that could happen.

One, nothing, the system realigns itself and continues to strengthen.

Two, the system weakens as it tries to pull together, moving farther west.

Third, the system reforms its circulation beneath the MLC, still missing the NE islands, but closer than forecast.

Will be interesting to see what tomorrow brings.

I live in Gulfport and have been off of the blog for one reason or another for the past two days, mainly dealing with weather related issues and no power or internet. I wanted to add a little reflection from several days ago. I think it was Taz that warned people of New Orleans that they should get out, especially if they were in certain areas. I recall one person saying not to worry about them, he had ridden out Hurrican Katrina and would be just fine. I remember wanting to say something but bit my lip and kept my mouth shut.
After all of the talk all week from Dr. Masters about this storm being an extremely large storm and no matter what the winds, hurricane or not that we were going to get a large storm surge and lots of rain. I also remember wanting to tell that person that he did not actually ride out Hurrican Katrina, he rode out the left side of the storm with the strongest winds being a 100 mile gusts in New Orleans. I hope and pray that some people have learned a lesson that every storm is different and just because it doesn't have strong winds doesn't mean that the strom surge can't cause a tremendous amount of damage just as it has done on the Miss. Coast and Louisiana once again. Keep us all in your prayers, it has been a stressfull several days and will continue to be for weeks to come for many. I think this storm suprised a lot of people in both States so hopefully people will listen up next time.

Leslie looks a little weaker tonight as she continues to move due West. If she stays weak she may not make the turn to the NorthWest in time, so the folks in the Islands need to be ready to act! My Goodness, could the NHC be wrong in their prediction of a turn to the North?

Don't bother quoting them... there are just some incredibly ignorant armchair cynics out there who believe they know what they are talking about. It's not nice to downplay a travesty such as Isaac's legacy left in Louisiana, and the reasons both of them have given give further evidence to their ignorance.

Inverted trough
An inverted trough is an atmospheric trough which is oriented opposite to most troughs of the mid-latitudes. Most (but not all) inverted troughs are tropical waves (also commonly called easterly waves).

Most troughs of low pressure in the mid-latitudes of the Northern Hemisphere are characterized by decreasing atmospheric pressure from south to north while inverted troughs are characterized by decreasing pressure from north to south. The situation is opposite in the Southern Hemisphere. Inverted troughs in both hemispheres move to the west from the east, while mid-latitude troughs generally move with the westerlies toward the east.

All troughs may be at the surface, or aloft, or both under various conditions. Most troughs bring clouds, showers, and a wind shift, particularly following the passage of the trough. This results from convergence or "squeezing" which forces lifting of moist air behind the trough line.

We don't get too many of these in San Diego county mountains,maybe 2-4 times in the summer,from easterly waves from the Gulf of Mexico and crosses over Mexico to arrive in Soo Cal during monsoon episodes. Had a very nice Thunderstorm today,with a lot of thunder and lightning. Twas quite the deluge for 20 minutes.

America is in deep trouble if its civilians are not able to handle a barely CAT 1 hurricane! The hysterical media coverage, 'specially by TWC, of this rain storm was an embarrassment (sp?). NBC buying TWC was the worse thing to happen to TWC. Its all about ratings for NBC so hype Isaac and shame TWC on air staff to promote Isaac as if its gonna be the end of LA/MS as we know it.
And for the president to go on nationwide TV to promote his concern for a piker of a Hurricane was also a shame. If Americans need to rely on the President of the USA for guidance on how to deal with a dinky hurricane then America is in deep do-do.
It was stunning to hear the consideration for retiring the name Isaac has been mentioned. Based on this event?-give me a break. It rained alot with the wind never really being a factor and thats reason enough to retire the name Isaac?!
The NHC center has had egg on its collected faces as it was wrong with its projections basically for Isaacs entire existence. Even the slowest of slow could see an eye was not forming for Isaacs entire existence. No eye of any significance means no hurricane maybe a TS.
And finally it is obvious that America is getting soft if how media and people react to the Isaacs and Irenes of this world as both were clearly not going to be the end of the world weather events but thats how its being promoted by government and media these days.
I dread the day when a CAT 4 or 5 gets into the Gulf, and heads for landfall in the US. The government and media reaction to this will be off the charts. IF Wolf Blitzer on CNN can label Isaac a 'national crisis' without any challenge to that claim then will Wolf et al think when the eventual CAT 4 or 5 gets into the Gulf-its the end of the world?

dude, you are wrong and hopefully you never encounter what some here have encountered. i live in Denham Springs, La....just east of Baton Rouge. thousands of homes, which have never flooded, are now flooded. i personally didn't get any damage but know of hundreds who did. at present, 50,000 people are evacuated due to a dam that they are afraid will break. it wasn't for us, but for thousands of people, Isaac was worse than Gustav and Katrina. before you go to making your rants, perhaps you should put yourself in some of these people's places. be thankful YOU aren't having to deal with the flooding. many more will flood in the next few days as our rivers are rising. funny how people are....as long as it isn't them, it's not important.

They're not going to forget Isaac next WMO, I'm betting retirement. Heck, they retired a tropical storm in 2001.
Any time a storm causes numerous human life should be retired and not heard from !!!

And should grow even more according to the models(Per NHC), that would explain why the GFS has the 1-2 inches in the NE Caribbean islands.
