This photo was posted on Facebook by Melissa Rich DeMarco Duffey with the message: "Found on NE 4th in Moore."

This exchange appears on a Facebook page -- May 19th 2013 OK Tornado Doc & Picture Recovery -- set up to return photos and documents to victims of a deadly storm system that has ripped across the state. 

Early Tuesday, the page included more than 100 family photos as well as documents.  A cat with one blue eye sat next to another of a woman in a camp chair holding two blond and grinning children. A grimy electricity bill was next to the stained photograph of a toddler sitting on Santa's knee.  An ultrasound photo showed what appeared to be a baby in utero.

The group featured 7,260 members at 5 a.m. ET. Users issued ground rules in the aftermath of the disaster, including advice to not post social security numbers or bank information. 

The page attracted others who were trying to help those in need, and cross-linked with other efforts that had sprung up in the storm's aftermath like Photos of Moore Oklahoma Tornado Pets Lost & Found. 

A nervous-looking black lab found in the wreckage left by the tornado was posted in the dead of night.

"3 dogs rescued from Moore tornado! Bathed, and cared for at rescuers home. Want to reunite them back with their families," the message with the photo read. "Prayer to all our furry friends and families."

And down the page another message from Farah Payton-Snider declared: "The black Lab is my (friend's)... dog Tin. Please call me ASAP."

Payton-Snider, 36, said she would close her flower shop and head into Oklahoma City first thing in the morning to try and help reunite people who had been hit by the tornado with their pets.

"I feel helpless, I want to be able to do something," said Payton-Snider, 36, who lives in Newcastle, Okla.

A monster tornado hit Moore, Okla., Monday afternoon, leaving scores dead as the threat for more storms continues.

Launch slideshow

About 9.5 million people remained under the threat of more "large and devastating" tornadoes Tuesday as the storm system that devastated the suburbs of Oklahoma City moved east, forecasters warned.

Weather Channel meteorologist Kevin Roth said early Tuesday that the threat area appeared to be east and south of Oklahoma City.

"Tornadoes, damaging wind gusts and large hail are possible throughout the threat area," Roth said.

He added that cities including Dallas-Ft. Worth, Austin, San Antonio, Shreveport, Texarkana and Little Rock were among the cities "close to the the larger tornado threat." 

"Another day of large and devastating tornadoes is possible this time from central/east Texas into central Arkansas," Roth said.

"Severe threat continues farther to the east Wednesday, although the overall severity appears to be lower."

Weather Channel forecaster Bill Karins told MSNBC that 9.5 million people lived in the area at most risk of more tornadoes. He said the likely pattern for twisters was the same as in recent days, with the biggest risk being in the late afternoon.

The National Weather Service said storms were expected Tuesday "from the Great Lakes across the Mississippi River Valley and into central Texas."

The agency issued a tornado watch late Monday for portions of east central Illinois, western and central Indiana, western Kentucky and southeast Missouri. The watch was in effect until 5 a.m. local time (6 a.m. ET). 

According to Roth, severe storms appeared possible from southeast New York to east Maryland on Thursday.

He added: "An early look at Memorial Day Weekend shows that most of the country should be quiet. The stormiest weather appears to be across the Plains and Midwest with scattered showers and thunderstorms."

A child calls to his father after being pulled from the rubble of the Plaza Towers Elementary School in Moore, Okla., on Monday.

When the sirens began blaring and teachers at Plaza Towers Elementary School in Moore, Okla., heard that a monstrous tornado was roaring toward their 57-year-old school and its youngest students, there was nowhere to hide.

They crouched in hallways and bathrooms, waiting, hoping and praying. Then "the school started coming apart," one neighbor who sought shelter at the school told the Associated Press. A teacher told NBC station KFOR that she draped herself on top of six children in a bathroom to shelter them.

The massive twister scored a direct hit at 3 p.m. (4 p.m. ET), tearing off the roof of the mostly one-story public school, a cinder-block building that had no chance of withstanding shrieking winds that may have topped 200 mph -- the powerful outer edge of what the National Weather Service said was at least an EF4 tornado, the second-most-powerful rating.

By Tuesday morning, the death toll at the school stood at seven. Officials said the children drowned in a pool of water at the decimated school. Rescuers were continuing to dig through the school’s rubble, from which several children were pulled out alive Monday evening.

It's unclear if any other children were killed or trapped alive.

Hysterical parents who had converged on the sprawling pile of broken concrete and twisted metal were later taken to a church to await word on the fate of their youngsters.

The two-mile-wide tornado wiped out entire city blocks of Moore, the hardest-hit Oklahoma City suburb, killing at least 51 people, including 20 children.

Exactly what transpired at Plaza Towers in the minutes before the tornado unleashed its destructive power has yet to be described. School officials evacuated fourth-, fifth- and sixth-graders to a church about a quarter-mile away before it touched down, but the younger students – kindergartners through third graders – remained at the 440-student school, according to KFOR in Oklahoma City. It was not immediately known why school officials divided the students.

Before and after aerial photos of Plaza Towers Elementary School.

But Mayer Nudell, a security and safety consultant, did not fault the decision to ride out the storm at the school.

“For something like a tornado, it’s fairly academic,” he said of the options that school officials would have had once the sirens began. “You don’t go out, and you don’t have much warning.”

Despite the carnage at the school, “shelter in place” has emerged as a staple of disaster planning and the strategy of choice for a range of emergencies, including tornadoes. And studies show it has a good track record of saving lives.

On May 3, 1999, for example, when another monster tornado roared through Moore, some 300 students and their parents were attending an awards ceremony in the West Moore High School auditorium. Though the twister badly damaged the school and tossed 150 cars in the parking lot like tinker-toys, those who hunkered down in the school’s hallways suffered only a few superficial injuries.

But there are experts who say that having a large number of people crowded into a big building is a bad idea when maximum-force tornadoes are sweeping through an area.

Chief among them is Joe R. Eagleman, a professor emeritus of the University of Kansas and author of “Severe and Unusual Weather,” a meteorology standard since it was first published in 1983.

He agrees that there was likely insufficient time between the first warning and the time the tornado hit the school, constructed in 1966, for Plaza Towers administrators to consider sending students home. “If time is short, being caught out in the open is not good,” he said.

But he said dispersing the students to their homes would have improved their odds.

“If there is sufficient warning time, the homes would be typically safer because they are smaller buildings and offer more opportunity to get in a downwind corner of the likely approach,” he said.

Eagleman is widely credited with debunking what was the prevailing school of thought on tornadoes for much of the last century: that the safest spot to take shelter is the southwest corner of a building. The reasoning behind the fallacy was that, since most U.S. tornadoes travel from west-southwest to the east-northeast, a twister would hurl debris into the northeast corner of whatever building it hit, likely taking out anyone cowering there.

But Eagleman conducted an extensive study after an EF5 tornado hit Topeka, Kan., in 1966, and found that the southwest corner – the direction from which a tornado was most likely to approach – was in fact the most dangerous area to hide.

“It used to be a rule that the southwest corner was the safest, no questions asked, but it was not based on any data,” he said.

Once Plaza Towers officials made the decision to have the students and teachers shelter in place, the school’s disaster plan would have kicked in. The staff and student body would likely have been well-coached, given the school’s location in “Tornado Alley” and Moore’s history of destructive tornadoes, though Eagleman noted that “it varies all over the place as to what the planning has been for severe storms.”

In any case, with no basement, students would have been moved into a hallway or small room away from the southwest corner of the building and any windows and instructed to either sit or crouch.

“You want a place that is structurally secure, without windows, so you don’t have to worry about flying glass,” said Nudell, who also is an adjunct professor of security management at Webster University in Webster Groves, Mo., and co-author of “The Handbook for Effective Emergency and Crisis Management.”

Both men said the school’s construction would have been important to its ability to withstand a powerful twister.

“The buildings that are made of reinforced concrete are typically very sturdy,” Eagleman said. “Those made with concrete blocks are not.”

But given the destruction visible after the tornado swept through Moore, it’s possible that no building would have withstood the intense pressure that the tornado brought to bear on the building, Nudell said.

Nudell also cautioned against jumping to conclusions about the emergency planning or safety of the school.

“When you get a tornado like the one that it sounds like hit Oklahoma, sometimes all the preparation and planning in the world doesn’t help you,” he said.

Michael Welch was midshift into his job at KFC in Newcastle, Okla., on Monday afternoon when he noticed hail pounding the parking lot outside the restaurant.

Then, as he looked into the distance, he saw the wall cloud of an enormous tornado rotating in front of him.

“It was very large and very fast,” he said.  “I could see debris flying all over.”

The 24-year-old cook grabbed his HTC cell phone and dashed into the parking lot and started recording video. “Probably not the best thing to do, but I did it.”

Most of his coworkers took shelter, but his manager stayed at the door while he filmed, Welch said.

“Oh, my God!” he screams on his video -- seen by thousands on NBC News and YouTube -- as the tornado, which killed at least 51 and injured scores more in the area, passes. 

He said an F4 tornado that hit his house in Blanchard on May 24, 2011, helped alleviate his fear.

“I think that gave me the courage to go ahead and go outside,” he said. “The power of the funnel cloud was amazing."

He said he had no idea a storm was coming until he saw it with his own eyes.

But now, his YouTube video showing a street-level view of the massive tornado plowing through Newcastle and Moore stands as an iconic record of the day’s event.

“I’ve talked to so many people today I can’t even count ,” he said.

The full extent of the destruction caused by the enormous tornado that ripped through Oklahoma was still being determined as night fell on Monday.  At least 51 people were killed, including seven children at an elementary school. Entire blocks of homes were flattened. At one hospital alone 85 patients, including 65 children, were being treated for injuries. And many were still missing. Here's a look at how Monday's horrific storm compares to some of the deadliest tornadoes in U.S. history:

Joplin, Mo. - May 22, 2011

Destroyed homes and debris cover the ground as a second storm moves in on May 23, 2011 in Joplin, Mo.

Peak winds, roaring over 200 miles per hour, destroyed the Missouri town, killing 162 people and causing an estimated $2.8 billion in damage, according to the National Weather Service. The Weather Channel's severe weather expert Greg Forbes estimates more than 17,000 people were affected. Nearly two years later, the town is still rebuilding.

The F4 tornado killed 65 during a record-setting day when 200 twisters spun through the Southeast. The spring and summer of 2011 was one of the most active, deadly and destructive periods of tornado activity in U.S. history. That year there were a reported 551 fatalities and $28 billion in damages, according to the Almanac.

At least 51 people, including 20 children, were among the victims of an enormous tornado that roared through the suburbs of Oklahoma City Monday, pulverizing entire city blocks and leaving behind miles of mangled cars and splintered wood.

Officials warned the death toll was likely to climb, making it among the deadliest tornadoes in U.S. history.

Forecasters warned that more "large and devastating" tornadoes were possible Tuesday with cities including Dallas-Ft. Worth, Austin, San Antonio, Shreveport, Texarkana and Little Rock potentially at risk.

At one hospital, 85 patients, including 65 children, were being treated for minor to critical injuries.

A monster tornado hit Moore, Okla., Monday afternoon, leaving scores dead as the threat for more storms continues.

“The whole city looks like a debris field,” said Mayor Glenn Lewis of the city of Moore, which appeared to be the hardest hit.

One of the many buildings to be totally destroyed was the Plaza Towers Elementary School where seven children drowned in a pool of water. The tornado tore the roof off the school about 3 p.m. local time. A teacher told NBC station KFOR that she draped herself on top of six children in a bathroom to shelter them.

It was not clear how many children still were missing. Students in fourth, fifth and sixth grade were evacuated to a church, but students in lower grades had sheltered in place, KFOR reported. More than two hours after the tornado struck, several children were pulled out alive.

The twister was a mile wide at its base, according to The Weather Channel. A reporter for KFOR said the tornado kicked up a cloud of debris perhaps two miles wide. The National Weather Service initially classified the storm as an EF4, the second-strongest type, with winds of 166 to 200 mph.

“It seems that our worst fears have happened today,” said Bill Bunting, a National Weather Service meteorologist in Norman, Okla.

Even before the death toll began to climb, television footage showed a landscape shattered — not the arbitrary damage of a tornado that leaves some homes untouched, but vast and utter obliteration.

Emergency workers stepped gingerly around piles of wreckage left on the foundations of homes. Other people simply walked around, dazed. Fires broke out in several places.

“I lost everything,” one man said as he walked through the ruins of a horse farm. “We might have one horse left out of all of them.”

Tiffany Thronesberry told the Associated Press that her mother, Barbara Jarrell, called her and screamed: “Help! Help! I can’t breathe! My house is on top of me!”

At one hospital in Moore, cars were “piled like Hot Wheels” in the parking lot, and police were searching them one by one and spray-painting X’s to mark them clear of victims, said Kurt Gwartney, news director for radio station KGOU.

An Oklahoma emergency management spokesman said a hospital was being evacuated after sustaining severe damage, and 16 ambulances were being sent to move patients. It was not clear whether it was the same hospital.

The tornado struck at mid-afternoon and tore a 20-mile path, said Rick Smith, another weather service meteorologist. He said it was on the ground for 40 minutes. Much of the storm’s rampage was captured on live television, perhaps alerting people in its path to seek shelter.

President Barack Obama declared a major disaster, making federal aid available to people in five counties. Gov. Mary Fallin asked the people of Oklahoma for patience and promised: “We will bring every single resource out that we can.”

Relief efforts sprang up. The Red Cross said it was opening a shelter, and the University of Oklahoma opened some of its housing for displaced families.

In addition to Plaza Towers, Briarwood Elementary School was heavily damaged, KFOR reported.

Grasping for comparisons, some people said it looked like Joplin, the Missouri town virtually wiped off the map two years ago when a tornado — this one an EF5 — blew through and killed 158 people.

Joplin city officials said Monday they were sending a team of 10 officers and three firefighters to Moore to help. “Giving back in whatever way we can,” the mayor said on Twitter.

For those living in Oklahoma, the ferocity was reminiscent of May 3, 1999, when a tornado registered wind of more than 300 mph, left 46 dead and damaged or destroyed more than 8,000 homes.

The tornado Monday also came one day after another cluster of storms in Oklahoma that killed two elderly men in the town of Shawnee. Tens of millions of people from Texas to the Great Lakes — an area covering 55 million people — had been warned to brace for the severe weather.

The Sunday storms destroyed mobile homes, flipped trucks and sent people across 100 miles running for cover. In Kansas, a weather forecaster was forced off the air as a tornado bore down on his station.

'Major damage' as huge tornado slams Oklahoma

Just call him Python Dundee.

A Miami man pulled an 18-foot Burmese python out of roadside brush and wrestled with it for 10 minutes before cutting its head off with a knife.

The 128-pound specimen turned out to be the biggest Burmese python ever captured in Florida, besting the previous record by more than a foot, wildlife officials said.

"I was pretty exhausted and I didn't want to get bit," Jason Leon, 23, said of the decapitation that ended his struggle with the massive constrictor.

For his trouble, Leon got thanks from the the Florida Fish and Wildlife Commission, which considers Burmese pythons an invasive species that wreaks havoc on the state's ecosystem.

"I would think a snake of that size could kill a very large animal," said Carli Segelson, a commission spokeswoman. "It could kill a deer, so a person would be comparable in size to that."

Leon, a college student studying marine biology, said he was riding ATVs with friends in a rural area on May 11 when one of them spotted about three feet of snake sticking out of some brush.

Leon, who used to keep snakes, had never seen a python in the wild and decided to get up close and personal with this one. It wasn't until he yanked him out that he realized how big it was.

As he held it by the neck, the female wrapped around his leg once, then twice and then headed for his waist. He kept grappling with it until he became worried it might sink its razor-sharp teeth into him.

A friend handed him a nine-inch knife and he sunk it into the snake, he said.

Two days later, Leon called wildlife officials, who took the snake and confirmed it was a record-setter. He agreed to donate the skeleton but has been promised the skin, which he plans to tan and put on his living room wall.

Officials said they are grateful the python is no longer roaming the wild and that Leon was not hurt.

"Anytime people are dealing with wildlife, we recommend they use common sense," Segelson said. "If you're going to approach a Burmese python of this size, you should have an understanding of what it takes to euthanize it."

A child is pulled from the rubble of the Plaza Towers Elementary School in Moore, Okla., and passed along to rescuers after Monday's tornado.

Seven children were found drowned at a tornado-flattened elementary school where rescuers were searching through the night for survivors as parents kept a heart-breaking vigil, officials said.

The students killed at Plaza Towers Elementary School were among at least 51 lives claimed by the monster twister that laid to Moore, Okla.

Several children and staffers were pulled alive from the ruins of Plaza Towers in Moore after the building took a direct hit Monday afternoon.

A little girl was lifted out by rescuers, while a small boy was carried to a triage area by a woman whose face was streaked with dirt and etched with worry.

In another image captured by an Associated Press photographer, a crowd of firefighters worked to remove a woman — her hair and clothes covered in dust and bits of debris — from the pile.

Those hopeful scenes were soon followed by devastating news as the Oklahoma City Medical Examiner's Office confirmed seven students were found dead in a pool of water.

It was unclear if any other children were killed or trapped alive.

Hysterical parents who had converged on the sprawling pile of broken concrete and twisted metal were later taken to a church to await word on the fate of their youngsters.

“Our hearts are just broken for the parents,” Oklahoma Gov. Mary Fallin said at the briefing.

“Our prayers are with you. We are working as quickly as we can to get through the debris and answer some questions about where loved ones are.”

The funnel cloud slammed two schools — Plaza Towers and Briarwood Elementary. There were no reports of casualties from Briarwood, although the building was heavily damaged.

At Plaza Towers, the fourth, fifth and sixth grades were evacuated to a church about a quarter-mile away from the 440-student school before the tornado touched down.

Students in kindergarten through third grade sheltered in place, according to NBC station KFOR. Some of those students had been in a hallway when the twister struck, others in bathrooms.

Plaza Towers Elementary School in Moore, Okla., before and after Monday's tornado hit.

"I had to hold on to the wall to keep myself safe because I didn't want to fly away in the tornado," one girl told the station.

James Rushing, who lives across the street, ran to the school to take shelter, thinking the building would be safer than his own home.

"About two minutes after I got there, the school started coming apart," he told The Associated Press.

The twister — deemed at least an EF4, the second-highest strength, by the National Weather Service — tore the roof off the building and knocked down its walls.

A truck that was tossed through the air landed in the spot where the school's main office would have been, KFOR reported. Books were scattered across pancaked slabs of concrete.

A crying man described to a reporter how he and others pulled a car off a teacher in the front of the building and found three children she had shielded with her body.

"Good job, teach," the man said, his voice choked with emotion.

A sixth-grade teacher told KFOR she laid on top of several children in a restroom to protect them from winds that may have topped 200 mph, and all survived.

Officials said search and rescue efforts would continue through the night.
