WINDS WILL FACE CERTAIN DEATH IF STRUCK.

 

POWER OUTAGES WILL LAST FOR WEEKS...AS MOST POWER POLES WILL BE DOWN

AND TRANSFORMERS DESTROYED. WATER SHORTAGES WILL MAKE HUMAN SUFFERING

INCREDIBLE BY MODERN STANDARDS.

 

THE VAST MAJORITY OF NATIVE TREES WILL BE SNAPPED OR UPROOTED. ONLY

THE HEARTIEST WILL REMAIN STANDING...BUT BE TOTALLY DEFOLIATED. FEW

CROPS WILL REMAIN. LIVESTOCK LEFT EXPOSED TO THE WINDS WILL BE

The caveat being that that's not for New Orleans, it's for the lower delta, about 90 miles away. And fortunately, that's mostly swampland, so there's not a hell of a lot there to be levelled (trees and such aside).

 

Even so...I had no idea NOAA would issue a warning worded like that. When I first read it, I thought it was a hoax.

When I was waiting for Jeanne and Frances to strike, noaa was the site i relied on all the time. For them to make statements like:

AS HOUSEHOLD APPLIANCES AND EVEN LIGHT VEHICLES

 

WATER SHORTAGES WILL MAKE HUMAN SUFFERING

INCREDIBLE BY MODERN STANDARDS.

 

is freaking unbelieveable...

 

 

This is gonna be awful

I guess they want people to take it seriously. And, whatever is left a week from now or so goes right through Buffalo, unless the projected track changes a lot. Y'all make sure you give it the finger when it comes by.

There is a statement pretty much the same for NO linked on the Drudge Report. I agree that it is so strong and disheartning that it looks fake, but FOX has been quoting that bulletin all day. I don't get moved to pray very often, but reading that got me in a mental pew.

Obviously this will be The Big One that everyone's been fearing.

 

When Hurricane Katrina hits New Orleans on Monday, it could turn one of America's most charming cities into a vast cesspool tainted with toxic chemicals, human waste and even coffins released by floodwaters from the city's legendary cemeteries.

 

Louisiana has lost more than a million acres of coastal wetlands in the past seven decades. The vast patchwork of swamps and bayous south of the city serves as a buffer, partially absorbing the surge of water that a hurricane pushes ashore.

 

Experts have also warned that the ring of high levees around New Orleans, designed to protect the city from floodwaters coming down the Mississippi, will only make things worse in a powerful hurricane. Katrina is expected to push a 28-foot storm surge against the levees. Even if they hold, water will pour over their tops and begin filling the city as if it were a sinking canoe.

 

After the storm passes, the water will have nowhere to go.

 

In a few days, van Heerden predicts, emergency management officials are going to be wondering how to handle a giant stagnant pond contaminated with building debris, coffins, sewage and other hazardous materials.

 

"We're talking about an incredible environmental disaster," van Heerden said.

 

He puts much of the blame for New Orleans' dire situation on the very levee system that is designed to protect southern Louisiana from Mississippi River floods.

 

Before the levees were built, the river would top its banks during floods and wash through a maze of bayous and swamps, dropping fine-grained silt that nourished plants and kept the land just above sea level.

 

The levees "have literally starved our wetlands to death" by directing all of that precious silt out into the Gulf of Mexico, van Heerden said.

 

It has been 40 years since New Orleans faced a hurricane even comparable to Katrina. In 1965, Hurricane Betsy, a Category 3 storm, submerged some parts of the city to a depth of seven feet.

But again...that's for the extreme tip of the delta. There's got to be maybe three household appliances in that whole parrish.

Eastern Great Lakes and the Ohio River valley are projected to get 4"-8" of rain from this storm.

 

And of course, all that rain that falls in the Ohio ultimately finds its way into the Mississippi, hence to New Orleans. And probably floods it more.

 

Kind of makes you wonder if we're going to see a modern metropolis be abandoned completely... :P

the winds have died down from 185 to 160 MPH, yet no one is saying that it is weakening.  Am I missing something?  Pressure has gone up few bars too...

421361[/snapback]

 

It's complicated. Pressure's about the same in the 11pm report (904 mb). But they're getting different wind readings from different sensors, and since they measure wind speed from a plane at altitude they have to adjust that to surface wind speeds...so until the storm hits land and surface instruments can directly measure, wind speeds are just an estimation, and there's questions about the adjustment factor in this case. Plus it looks like it's starting an eyewall replacement cycle, which typically weakens a storm temporarily (basically, it's taking a last deep breath, and can't blow as hard while it's inhaling).

 

So there's a lot that goes into wind speed...but pressure's a fairly consistent and independent measure of storm intensity, and the pressure hasn't materially changed, so they'll say it's maintaining its strength.

It won't be a hurricane any more by then.  Lots of rain, though.

Yep I know. Gonna have to gas up the cars and buy some supplies tomorrow. I lived in Birmingham AL in 1995 when Hurricane Opal came thru. It was only a Cat 3 and had already degraded to a tropical storm but that was lots and lots of rain.

Haven't read the whole thread but is anyone else worried that the SuperDome might not withstand 175 mph wind?

 

This person is worried:

For example, the Superdome's outer skin is composed of 500,000 square feet (146,500 square meters) of anodized aluminum

 

Lovely ... sheets of aluminum flying around in 160-175 mph winds.

 

But wait! It gets better!

 

Contractors building the Superdome also found that it required efforts and techniques that were a bit out of the ordinary, especially in the construction of its roof. For this building, the largest clear span steel structure in the world ... is literally held together by its roof. In its flying - saucer-shaped design , the walls of the Superdome literally hang (for want of more descriptive term) from the roof, with the force vectors at foundation level pointing away from the center.

 

So basically, the outside is riveted panels of aluminum suspended from the roof. The director of FEMA has already warned that even buildings design to withstand the force of a Cat 5 hurricane will NOT be able to withstand winds of 160+ mph.

 

The term "death trap" comes easily to mind here. Do we never learn?

 

Worst case scenario is tens of thousands are dead and this thing makes 9/11 look like a day in the park. We are in a world of sh-- right now.

Well, i'm off to bed. The sick thing is, when I wake up, many people that are alive right now won't be (which i realize happens every day, but it just weird seeing the cause of these deaths on a radar screen), many enormous structures that are standing will be fallen, and an area of land that is now just getting rained on will be completely under a toxic lake of water, human waste, and corpses. Damn....

3 people already dead. Deaths while evauating people from a nursing home...

 

 

and one last thing tonight... the Superdome has ONE generator... where is it located? On ground level of course... flooding could destroy it...

 

That should be a peaceful environment. A superdome with 40,000 people in it ... hot as hell, dark as night... flooding football field in the middle...

Now they're saying it should only be Cat 4 when it hits N.O. so that should help.

421419[/snapback]

 

 

National Hurricane Center Director Max Mayfield said: "There's certainly a chance it can weaken a bit before it gets to the coast, but unfortunately this is so large and

so powerful that it's a little bit like the difference between being run over by an 18-wheeler or a freight train. Neither prospect is good."

 

 

My Prayers are with the people of the big easy
