BREAKING: Dam Failure Imminent due to Isaac Flooding

And these are all ADDITIONAL inches of rain!

There are 3 more months of hurricane to go yet! September is a bad month for them. October and November they taper off. A bad thing that can happen is to have hurricane on top of a hurricane.

Much thanks for pin!!

I don't think it's meant like that, I read it as they think it will happen but it may not.

TROPICAL STORM ISAAC DISCUSSION NUMBER 38
NWS NATIONAL HURRICANE CENTER MIAMI FL AL092012
1000 AM CDT THU AUG 30 2012

CENTER FIXES USING SURFACE OBSERVATIONS AND NOAA DOPPLER WEATHER
RADARS INDICATE THAT ISAAC IS MOVING NORTHWESTWARD AT 330/08 KT.
THE FORECAST TACK AND REASONING REMAIN BASICALLY UNCHANGED FROM THE
PREVIOUS ADVISORY. ISAAC AND ITS REMNANTS ARE EXPECTED TO BE
STEERED NORTHWARD AROUND THE WESTERN PORTION OF A SUBTROPICAL RIDGE
THAT IS LOCATED OVER THE SOUTHEASTERN U.S. THROUGH DAY 2...AND THEN
TURN NORTHEASTWARD AND EASTWARD ON DAY 3-5 AS THE SYSTEM MOVES INTO
WEAK MID-LATITUDE WESTERLY FLOW. THE OFFICIAL TRACK FORECAST IS
VERY CLOSE TO THE PREVIOUS ONE...AND LIES CLOSE TO THE LATEST
DYNAMICAL MODEL CONSENSUS.

THE INITIAL INTENSITY HAS BEEN DECREASED TO 35 KT...AND THAT IS IN
SMALL AREA OVER WATER BETWEEN SOUTHEASTERN LOUISIANA AND THE
MISSISSIPPI COAST...AND PERHAPS EXTENDING A FEW MILES INLAND.
ISAAC WILL CONTINUE TO WEAKEN OVER LAND AND IT IS LIKELY TO BECOME A
TROPICAL DEPRESSION BY THIS EVENING...AND BECOME A POST-TROPICAL
REMNANT LOW BY SATURDAY...IF NOT SOONER. THE OFFICIAL INTENSITY
FORECAST IS SIMILAR TO THE PREVIOUS ONE...AND CLOSELY FOLLOWS THE
DECAY-SHIPS STATISTICAL-DYNAMICAL INTENSITY MODEL.

HEAVY RAINFALL AND A SIGNIFICANT FLOOD THREAT WILL CONTINUE TO
SPREAD INLAND ACROSS PORTIONS OF THE CENTRAL UNITED STATES DURING
THE NEXT SEVERAL DAYS. WATER LEVELS ALONG THE NORTHERN GULF COAST
WILL REMAIN ELEVATED THROUGH AT LEAST THIS MORNING. THE THREAT FOR
TORNADOES WITH THIS SYSTEM ALSO APPEARS TO BE INCREASING TODAY.

FORECAST POSITIONS AND MAX WINDS

RT @nwsneworleans: Looks like if the dam breaks, there would be about a 2-3 ft rise at Osyka.

Potential dam break at Percy Quinn Park on the Tangipahoa River (south of McComb, MS). #Isaac

yah, there was no maybe about it was there?....

I have heard that if ground is too dry/hard, then the water runs right over it and doesn't soak in or get absorbed.

Everything is imminent on GLP.

My prayers go out to all of the people in the path of ISAAC

The human side of Isaac. Residents in Slidell, LA flooded out of their homes talking with Jim Cantore

Yes...true. i live in Arizona and that is precisely what happens. We always hope for a light, soaking rain before a hard monsoon so the ground can absorb more. But if not..the torrential rain just sends rivers right over the top in flash floods.

In fact there have been reports from farmers in drought areas that the soil is so dry and cracked that a big downpour would only wash over the top and not soak in. Sad situation.

The whole country is in a sad situation. I wish more people would just take time to get on their knees in earnest prayer....and have a heart to reach out and help the ones who need and can't help themselves.

Could make more difference than anything.

Godspeed to those in the midst of this




:flowers:

Haven't seen any updates about the dam.
Hope they get the people out before it breaks.

No I don't see it that way, just a statement of very high probability.

Oh yea, Oh yea!"

It was brief, but tornado in Pascagoula, MS completely destroyed this home.

WTF that many people and they thought it would happen but they don't order mandatory eavac till it's already broke, I hope people saw the initial warning and left already.

Just received word from my cousin in Mississippi. She installed a drainage system on her property and it is unable to keep up with the rain. Her yard is flooded and the water is getting close to coming in the house. (She is assuming it is from the relentless rain.) She is about 1/2 hour outside of Jackson (to the south) in an affluent neighborhood.

I have been real sick so I haven't been able to keep up with what is going on with the storm. I hope it ends soon.

There are a lot of variables in the runoff. Probably the three biggest are soil type, vegetation and ground cover. If the soil is clayey or silty then it isn't as "permeable" as say good topsoil where water will infiltrate quite easily. That is there are few open voids in the soil for water to seep into.

Vegetation also affects runoff, as certain types of vegetation can retard surface water flow more highly than others.

Finally, if you have a lot of rock outcrops water can just sheet flow over the ground surface.

Of course these are technical details and as usual this web site has little tolerance for details or facts.

Hyperbole.

how terrible!
