Hurricane Katrina Report by Tornado Tim
Hurrican Katrina 175 mph winds GOES-12 August 28th 2005Katrina grew to a Category 5 hurricane with winds over 175 mph and recorded a minimum central pressure of 902 millibars, which is the fourth lowest on record for an Atlantic hurricane, according to NOAA's National Climatic Data Center.  As it moved inland it weakened to a Category 4 but Katrina still caused extensive damage and flooding. Many buildings experienced complete and total failure due to high winds and storm surge. Hurricane Katrina made a direct hit on Gulf Port Mississippi pounding it with 145+ mph sustained winds and some gusts even higher. Other areas were beaten with sustained winds of 135 mph.  Flooding was widespread, low areas were completely under water. This is a major disaster from Slidell Louisiana to Mobile Alabama.  The destruction is overwhelming and the ability for anyone to grasp the extent of this catastrophe is impossible. Sadly the storm was so strong and large, covering about 90,000 square miles or 233,098.93 square kilometers, that many people who needed to be rescued were left unaided. It became impossible to rescue people during the storm without dangerously risking the lives of the rescuers.

Gov. Haley Barbour of Mississippi told reporters that until the winds died down they just could not do any search and rescue, making some residents worst nightmare seem endless.  People had been warned before that rescue would likely be impossible because of the ferocious and awesome power this storm would possess.  Some people stayed even after hearing this warning, others had to stay with no way to evacuate.  The problem after the storm left was the vastness of the rescue and that major roads were destroyed.  Days after the storm, many people were still needing rescue, but no one came for them. Many people trapped in their own homes, waiting, some dying.  Unbelievably as late as September 2nd, we still didn't know when everyone would be rescued and receive the help needed.
Fast Facts: Until Katrina the worst natural disaster in United States history had been a hurricane that killed 8000+ people in Galveston, Texas in September of 1900.
Katrina as it makes landfall  1615z  August 29 2005Storm surges of near 30 feet(9 Meters) the highest ever recorded were reported with hurricane Katrina, although not in New Orleans as originally had been feared. Instead those east of New Orleans were the ones buried under an ocean of water as water surged onshore from the hurricane. Gulf Port Mississippi, Biloxi Mississippi, were hit with a monstrous storm surge. Credit NOAA - Large heavy objects moved like toysSt. Bernard Parish in Louisiana found itself completely under water as Katrina moved by. Unprecedented, catastrophic, horrific are all words that describe what happened.  The destruction was far worse than anyone could believe. In some areas all the homes were annihilated. Surprisingly, the majority of New Orleans flooding was not caused by storm surge, but levee breaches that grew after Katrina's assault bringing deadly destruction to the city.  
Fast Facts: Nine out of ten hurricane fatalities are caused by the storm surge.
WHAT HAPPENED?
Friday Aug. 26th
GOVERNOR BLANCO DECLARES STATE OF EMERGENCY
BATON ROUGE, LA--Governor Kathleen Babineaux Blanco today issued Proclamation No. 48 KBB 2005, declaring a state of emergency for the state Louisiana as Hurricane Katrina poses an imminent threat, carrying severe storms, high winds, and torrential rain that may cause flooding and damage to private property and public facilities, and threaten the safety and security of the citizens of the state of Louisiana The state of emergency extends from Friday, August 26, 2005, through Sunday, September 25, 2005, unless terminated sooner.
Saturday Aug. 27th  36 hours before Hurricane Katrina crashed into the Gulf Coast, New Orleans Mayor C. Ray Nagin received a late night call on Saturday from Max Mayfield, director of the National Hurricane Center in Florida and was warned that Katrina was a "worst-case" scenario.  Mr. Mayfield of NHC suggested the Mayor order a mandatory evacuation  of New Orleans. Finally Sunday morning Mayor Nagin decided to order an evacuation of the city.
Sunday August 28th, 2005
a mandatory evacuation was ordered for the City of New Orleans early Sunday morning by Mayor Ray Nagin as catastrophic Hurricane Katrina headed northwest.  Gov. Kathleen Blanco alongside of the mayor stated at a news conference that President Bush called and personally appealed for a mandatory evacuation for the low-lying city, which is prone to flooding. Everyone was asked to leave the area, but later we found many choose not to.

Quoting New Orleans Mayor C. Ray Nagin - "Ladies and gentlemen, this is not a test. This is the real deal. Board up your homes, make sure you have enough medicine, make sure the car has enough gas. Do all things you normally do for a hurricane but treat this one differently because it is pointed towards New Orleans."
Gov. Kathleen Blanco:
"I think this storm is bigger than anything we have dealt with before, This is not a minor problem."
Ralph A. Latham Jr., the director of Emergency Management Operations for Mississippi:
"I'm afraid this is the one we've dreaded, I don't think the scenario could be any worse for us."

..DEVASTATING DAMAGE EXPECTED

Hurricane Katrina is a most powerful hurricane with unprecedented strength...rivaling the intensity of hurricane Camille of 1969. Most of the area will be uninhabitable for weeks...perhaps longer. At least one half of well constructed homes will have roof and wall failure. All gabled roofs will fail...leaving those homes severely damaged or destroyed. The majority of industrial buildings will become non functional. Partial to complete wall and roof failure is expected. All wood framed low rising apartment buildings will be destroyed.

Concrete block low rise apartments will sustain major damage...including some wall and roof failure. High rise office and apartment buildings will sway dangerously...a few to the point of total collapse. All windows will blow out. Airborne debris will be widespread...and may include heavy items such as household appliances and even light vehicles. Sport utility vehicles and light trucks will be moved. The blown debris will create additional destruction.

Persons...pets... and livestock exposed to the 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 killed. An inland hurricane wind warning is issued when sustained winds near hurricane force...or frequent gusts at or above hurricane force.

Even after all these terrible warnings, many choose to ride out the storm all along the coast.

New Orleans Evacuation Map New Orleans Contraflow Plan
Redcross Evacuation Plans  PDF file
New Orleans City Hurricane Plans The city had plans for those who didn't have a way to escape.
".......Special arrangements will be made to evacuate persons unable to transport themselves or who require specific life saving assistance. Additional personnel will be recruited to assist in evacuation procedures as needed." 
Also the city had in place what to do after a levee break.
Under section
7 it says:  "Mitigation actions following natural disasters and post disaster plan development. In response to a major destructive storm, future plans call for the preparation of a post disaster plan that will identify programs and actions that will reduce or eliminate the exposure of human life and property to natural hazards. To direct the City's hurricane recovery operations, the Mayor will appoint a Recovery Task Force (RTF)."
 

Due to the devastation of this storm it may be hard for people to get any tax deductions due to property damage. Being properly prepared for the storm and having homes and personal possessions protected correctly is the best way to deal with this situation. Having your tax preparation done early and covering all of your assets is a necessity when dealing with storms of this nature.


NOTE: One thing we Americans have learned from Hurricane Katrina is who has control of what resources when a disaster hits an area. The Federal Government is limited in its control over each states National Guard units. Freedom in the United States is highly valued, and each state does not want the Federal Government to have too much control over them.  According to as of September 5th 2005  Louisiana Gov. Kathleen Blanco still had refused to sign over control of the National Guard to the federal government.  Instead Gov. Kathleen Blanco hired a Clinton administration official, former Federal Emergency Management Agency chief James Lee Witt, to help run relief efforts.   

(According to
By John Yaukey, Gannett News Service) in the USA today Posted 9/13/2005
Bush suggested "federalizing" Louisiana's Guard forces when the chaos in New Orleans began escalating.  The President wanted to  invoke the Insurrection Act, which permits the military use of federal troops on U.S. soil to put down violence that local authorities are incapable of handling, but Gov. Kathleen Babineaux Blanco objected.  Under the National Defense Act of 1916, the president can federalize a state's National Guard troops in an effort to centralize control over a chaotic situation. 

So the military is NOT allowed to come in and police a city at the Presidents will.  The role of domestic law enforcement is controlled by the 1878 Posse Comitatus Act  which restricts military forces from policing American cities. So when troops were sent in the Pentagon made it clear that the thousands of forces sent there would not perform police functions but  worked within US law and regulations. 

It appears that since our president cannot seize control of a city and state at will, that many people were left without help. So, the question is, should we give our president free reign to take over when he feels it is necessary. Do you want to give president Bush the right to decided when to take over your city and your state at his will because he thinks he needs to?

Hurricane Katrina: Why the Red Cross not in New Orleans? On September 7th I found many reports that the Red Cross was ready the moment after the storm passed through to go into New Orleans. This makes sense as most every city I have seen destroyed by tornadoes is quickly greeted with the welcome sign of the American Red Cross. They are usually right behind the police, fire departments and rescue squads.  But they weren't in New Orleans as they were blocked from going into the city by the Louisiana State Homeland Security authorities.
Here is what the Red Cross posted on their site.
"Access to New Orleans is controlled by the National Guard and local authorities and while we are in constant contact with them, we simply cannot enter New Orleans against their orders. The Louisiana state Homeland Security Department had requested--and continues to request--that the American Red Cross not come back into New Orleans following the hurricane. Our presence would keep people from evacuating and encourage others to come into the city."

Below are my notes of the events looking all the way back to the official warnings and predictions.
Monday August 29th: Our friend Doug was filming the hurricane as it made landfall. He made it alive through it all and posted some blogs on his website.
Tuesday August 30th Morning: Waking up Tuesday morning we found many areas had not seen any rescue teams. Doug my friend who was filming the event is no longer responding to calls or emails. His last blog was Late Monday night so I became concerned about his welfare. Reports of what was happening in New Orleans was confusing at best. Slowly it became clear things were far worse than any realized. It appears a levee has broken and reports state New Orleans is flooding.

Fast Facts: As of August 30th 2005, the National Hurricane Center lists Hurricane Andrew in 1992, as the most destructive storm to hit the United States. It caused damage estimated at $26.5 billion and was a category five hurricane. Katrina...............$$$$$$$$$$$
August 30th Afternoon:
New Orleans did not take a direct hit from Katrina. It didn't matter. New Orleans began flooding hours after the storm left. At first it was unknown where all the water was coming from, but it was seeping into the city slowly turning it into a dirty lake. Then reports came in that several levies became breached, but experts didn't think that explained all the water coming into the city, the confusion began.  80% of the city became submerged underwater and desperate attempts were made to repair the levies, but without success. Tuesday's efforts to stop the flooding were worthless.  Both airports went underwater. At one of the New Orleans airports all that could be seen were a few buildings and the control tower sticking up out of an ocean of water like a buoy in the sea.....Incredible sight....Most roads leading out of the city were blocked, others became impassible by the flooding. Getting in and out of New Orleans was a problem. Large
sections of the Interstate 10 high-rise bridge over Lake Pontchartrain, east of New Orleans and south of Slidell, had collapsed.

How many dead? Scores............. The total numbers will be difficult to accept.......Sadness...... Everyone is afraid to put a number on the deaths, but many fear it will be high, very high. Reports of dead bodies floating in the water have been heard all day and were confirmed by the mayor of New Orleans. "We're not even dealing with dead bodies," Mayor Ray Nagin said. "They're just pushing them on the side." Rescue of the living is of the highest priority. Areas around Biloxi Mississippi and Gulf port are reported to have sustained the full force of the hurricane winds and the worst of the storm surge.

August 31st  - late afternoon: The Refugees of the United States
Click to read -- President Outlines Hurricane Katrina Relief Efforts
It is estimated that about 1 million Louisiana residents have been left without homes. Mothers with babies, young children, elderly, all refugees in their own county.  We are talking tens of thousands of refugees in New Orleans alone and the numbers keep rising as people wander from the polluted waters to higher ground. I cannot fathom this happening in the great United States. Many people still have not been rescued in New Orleans as of 7PM EST time. Help seems painlessly slow as TV stations across American display images of families looking for help, yet they are left stranded.  It appears to me that far less evacuated then many thought. It is evident that many people did not heed the warnings given, a problem that I have witnessed over and over across the United States in regards to people's response to weather warnings issued. 

More than 1 million residents across Louisiana, Mississippi and Alabama, remain without electricity on August 31st. The normal comforts of living will not be available for a long time. 

In Mississippi, the bodies of those who died from hurricane Katrina were being moved to the morgue in hard-hit Harrison County. Officials say fatalities of over 100 are expected. The worst of the hurricane damage is reported in Mississippi, but New Orleans is getting most of the national news reports due to the ongoing disaster there.

Refugee camps are being setup and organized from Huston Texas to areas north of New Orleans. Military ships and helicopters are converging on New Orleans along with a 500 bed mobile hospital. Many will perish before help arrives.  Death counts have still not been given, but it is insinuated that it may be in the thousands.   For all our technology, we have yet to triumph over the most powerful forces on earth - natural disasters like Katrina.

President Bush in a televised address from the White House said,
"We're dealing with one of the worst national disasters in our nation's history,"

The only good news today was that our friend Doug who was filming the hurricane has now escaped New Orleans and is back in Minnesota alive.

September 1st  Updated 11 pm EST Evening  I have been chasing storms for over 10 years now and watched entire communities in ruin get help quickly, but usually from near by communities. In this case, the nearby communities were also destroyed.  I have never in my life seen anything so sad as the slow rescue of the victims of hurricane Katrina.  But I have to admit, I don't think anyone ever envisioned a disaster this immense in the United States. 90,00 square miles or 233,098.93 square kilometers, has been seriously damaged or destroyed. Still, with the apocalyptic warnings given how could plans not been in place for a massive rescue. Just read the warnings further down in this report and ask yourself how such warnings would not have tens of thousands of troops in the area hours after Katrina hit. I wonder if officials even believed their own predictions.

Fires broke out today in New Orleans, lootings, people died in the very shelters they were told to go to. Refugees sit next to dead bodies, waiting for the help promised, but what comes is too little, and it is quickly becoming to late. Anarchy has been breaking out, the city is not safe with rapes and beatings taking place seemingly without fear of law enforcement chasing after the criminals. Mob rule is now the law, thugs rule the city, it appears to be taken over by the lawless. Local police are turning in their badges. If this is the fastest response that any state can give to a crisis situation, God help us.

Louisiana Lt. Gov. Mitch Landrieu confirmed that 30 people died at a nursing home in St. Bernard Parish. Arial views show that Long Beach is no longer a city, it is completely wiped out. Headlines talk of a major shortage of jet-fuel at US airports if jet-fuel disruption is not fixed soon. Reports are showing up in  major news papers across the US that airports in the East and Southeast could run out of jet fuel as soon September 5th if refinery and pipelines aren't turned back on soon. Shortages appear most severe at airports in Charlotte, Tampa, Orlando and Fort Myers, Fla. Some of my own relatives are saying some gas stations in Florida have run out of gas already today. Gas is becoming hard to find in some areas, states no where near the hurricane damage. Arizona, Carolina, West Virginia, and Wisconsin.

The refugee numbers keep rising just as I had feared. It appears my predictions of far fewer people leaving New Orleans before the storm were correct as a seemingly countless number of people are roaming the devastated city. Some estimations are now up to 150,000 people left in and around the New Orleans area. According to the 2000 census, New Orleans's population was 484,674 and the New Orleans metropolitan area's population 1,337,726.  The saddest problem of all is many people didn't have the financial means to get out.  I only wonder if anyone, anyone at all thought of all the poor who had no way to evacuate from New Orleans to Mississippi. I am asking a question I would love to hear answered. When the warnings go out for a need to evacuate, what plans were made for the poor, to get them out? How many busses were supplied on Sunday, how many transportation vehicles were sent ahead to help them leave?

The Dead: While Mississippi started collecting their dead on Wednesday, New Orleans is such a monumental disaster bodies are left floating in the polluted flood waters from Lake Pontchartrain.  Fears mount over the fate of many internationally known musicians who are missing. 'Fats' Domino and others fates are still unknown at this time.

The Levee: Still a wide open gap with no resolution and no hope to even start pumping out water from New Orleans. 

How Bad is it?
This city will not be what it was for many years, if ever. First, you can't just go back into homes and dry them out. Read Flooded Homes  The reality is many of the buildings and homes in New Orleans will never be inhabitable again, they will need to be destroyed. YEARS of Rebuilding...

September 2nd  - Finally Help and Hope Arrived
Read - President Tours Biloxi, Mississippi Hurricane Damaged Neighborhoods

President George W. Bush spends a moment with a victim of Hurricane Katrina during his walking tour Friday, Sept. 2, 2005, of Biloxi, Miss. "You know, there's a lot of sadness, of course," said the President of the devastated area. "But there's also a spirit here in Mississippi that is uplifting." White House photo by Eric Draper Hope has returned as countless numbers of rescue teams, helicopters, boats, fire trucks from around the country, almost every state in the United States has sent help. FEMA in large numbers arrived with semi after semi of life saving water and supplies. Evacuations flowed at a steady stream and hospitals begin to be rescued in greater numbers.
Credit NOAA Roads covered or destoyed along beach Soldiers just back from Iraq and armed for war, moved in to restore order. Vehicle after vehicle amassing in heartwarming numbers. Coast guard ships, military vehicles, special equipment bringing hope. Today is the first day I believe we can survive this catastrophe since the Hurricane hit. The mob rule and anarchy that has ruled New Orleans for days is about to end. Sadly it was revealed today almost 1/4 of the New Orleans police department abandon their posts and walk off from their jobs and even took food and water from the stores like the others.

"Right now there are more than 21,000 National Guard troops operating in Louisiana and Mississippi, and more are on the way. More than 13,000 of these troops are in Louisiana."
President Bush said.
As of this morning the levee breach is still not fixed, but work continues. Help is coming at a rate that is historic. A massive airlift like nothing before is taking place, the US military has taken charge under the direct command of General Russ Honore. 

'Fats' Domino was finally rescued Friday night in New Orleans, according to wire reports. And Irma Thomas, the Queen of New Orleans soul, was located in Baton Rouge, where she escaped to the home of her aunt.
September 5th According to FEMA's website
To date:
  • In Louisiana, there are 30 Disaster Medical Teams (DMAT); 2 Veterinary Assistance Teams (VMAT); 1 Mental Health Team; and 4 Disaster Mortuary Operational Response Teams (DMORT)
  • In Mississippi, there are 11 DMATs; 1 Mental Health Team; 2 VMATs; and 4 DMORTS
  • There have been 9,400 hospital evacuations and all hospitals as well as 30 nursing homes in New Orleans have been evacuated
  • A portable hospital from Nevada arrived at New Orleans airport yesterday
  • The 1,000-bed USS Comfort is scheduled to arrive in the Gulf Coast area tomorrow
  • A Department of Defense mobile hospital is operational at the New Orleans airport
  • DMORT sites are set up in Gabriel, La., and Gulfport, Miss. Each site has four DMORT teams and one portable morgue.
  • As of yesterday, 229,328 people were in 679 shelters in 12 states
  • Two million meals ready to eat (MREs) were delivered to Gulfport, Miss., last night, making a total of 8.5 million MREs that have been delivered in response to Hurricane Katrina
  • FEMA is working with the American Red Cross to provide vouchers to evacuees in shelters
  • Three Disaster Recovery Centers (DRCs), where hurricane victims can get assistance, are opening in Alabama today making a total of five there; four DRCs are open in Texas
  • Disaster food stamps are available in Louisiana
  • More states are preparing to receive Hurricane Katrina evacuees -- 15 states and the District of Columbia are currently housing or preparing to house evacuees
  • 1.1 million barrels of diesel have been shipped to New Orleans
This disaster is a learning lesson for all of the United States. It teaches us how laws regulate even rescue and evacuations. We are learning that by law the Federal government cannot just move in with any and all their resources, but instead the local government must take the leading role in the process. Laws regulated much of the rescue events and timing they could be deployed.

     We are all learning that when the worst possible scenario hits the US even the best of plans will fall far short of what is needed. Severe weather events can be beyond the scope of our imagination and we must all understand that natural disasters are far bigger and stronger than anything we possess. We are at the mercy of such catastrophic events as Katrina.
     Who is at fault? The best answer to that question is Katrina, the hurricane, it did this. Only time will tell how large and impossible this rescue really was, but I would have expected the leaders of the New Orleans area to have made better plans on how to deal with this type of situation, especially since it was known for a long time that this could happen. Yet, can such a huge event as this ever be totally prepared for, I really doubt it. Those who were in charge of the New Orleans area at the time of the disaster and were responsible in preparing for a hurricane and the safety of the residents are listed below. Mayor Nagin and Governor Blanco did warn the residents on Sunday and asked everyone to leave the area before the storm would hit.

U.S. Senator Mary Landrieu U.S. Senator David Vitter
The Positive - What You can do: One lesson for all of us to learn from this nightmare is to check with your local and state officials to find out what disaster plans they have for your own local area. Every community, every city and every state must have a plan to deal with what ever potential disasters they may face. After a disaster hits is not the time to find out what their plan was. In other words, you must take action to keep this from happening in your area. You are responsible for those who run your counties, cities and states and it is your responsibility to know what plans they have in place. 

Please check out NOAA's StormReady program. http://www.stormready.noaa.gov/   StormReady, a program started in 1999 in Tulsa, OK, helps arm America's communities with the communication and safety skills needed to save lives and property– before and during the event. StormReady helps community leaders and emergency managers strengthen local safety programs.  Take the responsibility and get your local officials involved. They even have a TsunamiReady program. http://www.stormready.noaa.gov/tsunamiready/index.htm
