Rescue workers raced to complete the search for survivors and the dead in the Oklahoma City suburb where a mammoth tornado destroyed countless homes, cleared lots down to bare red earth and claimed 24 lives, including those of nine children.

Scientists concluded the storm was a rare and extraordinarily powerful type of twister known as an EF5, ranking it at the top of the enhanced Fujita scale used to measure tornado strength.

Those twisters are capable of lifting reinforced buildings off the ground, hurling cars like missiles and stripping trees completely free of bark.

After nearly 24 hours of searching, Moore’s fire chief said he was confident there were no more bodies or survivors in the rubble. ‘‘I’m 98 per cent sure we’re good,’’ Gary Bird said at a news conference with the governor, who had just completed an aerial tour of the disaster zone.

Authorities were so focused on the search effort that they had yet to establish the full scope of damage along the storm’s long, ruinous path.

They did not know how many homes were gone or how many families had been displaced. Emergency crews had trouble navigating devastated neighborhoods because there were no street signs left. Some rescuers used smartphones or GPS devices to guide them through areas with no recognisable landmarks.

The death toll was revised downward from 51 after the state medical examiner said some victims may have been counted twice in the confusion. More than 200 people were treated at area hospitals. By Tuesday afternoon, every damaged home in Moore had been searched at least once, Bird said.

His goal was to conduct three searches of each building just to be certain there were no more bodies or survivors. The fire chief was hopeful that could be completed before nightfall but efforts were being hampered by heavy rain. Crews also continued a brick-by-brick search of the rubble of a school that was blown apart with many children inside.

No additional survivors or bodies have been found since Monday night, Bird said. Survivors emerged with harrowing accounts of the storm’s wrath, which many endured as they shielded loved ones.

Chelsie McCumber grabbed her 2-year-old son, Ethan, wrapped him in jackets and covered him with a mattress before they squeezed into a coat closet of their house. McCumber sang to her child when he complained it was getting hot inside the small space. ‘‘I told him we’re going to play tent in the closet,’’ McCumber said, beginning to cry.

‘‘I just felt air so I knew the roof was gone,’’ she said Tuesday, standing under the sky where her roof should have been. The home was littered with wet gray insulation and all of their belongings. ‘‘Time just kind of stood still’’ in the closet, she recalled. ‘‘I was kind of holding my breath thinking this isn’t the worst of it. I didn’t think that was it. I kept waiting for it to get worse.’’ ‘‘When I got out, it was worse than I thought,’’ she said.

Oklahoma Governor Mary Fallin lamented the loss of life, especially of the nine children killed, but she celebrated the town’s resilience.

‘We will rebuild, and we will regain our strength,’’ Fallin said. From the air, large stretches of the town could be seen where every home had been cut to pieces. Some homes were sucked off their concrete slabs. A pond was filled with piles of wood and an overturned trailer. Also visible were large patches of red earth where the tornado scoured the land down to the soil. Some tree trunks were still standing, but the winds ripped away their leaves, limbs and bark. In revising its estimate of the storm’s power, the National Weather Service said the tornado, which was on the ground for 40 minutes, was a top-of-the-scale EF5 twister with winds of at least 320 kph.

The agency upgraded the tornado from an EF4 based on reports from a damage-assessment team, said spokeswoman Keli Pirtle. Monday’s twister was at least a half-mile (nearly a kilometer) wide, and it was the first EF5 tornado of 2013. Other search-and-rescue teams focused their efforts at Plaza Towers Elementary School, where the storm ripped off the roof, knocked down walls and destroyed the playground as students and teachers huddled in hallways and bathrooms.

Seven of the nine dead children were killed at the school, but several students were pulled alive from under a collapsed wall and other heaps of mangled debris.

Rescue workers passed the survivors down a human chain of parents and neighborhood volunteers. Parents carried children in their arms to a triage center in the parking lot. Some students looked dazed, others terrified.

Plaza Towers and another school in Oklahoma City that was not as severely damaged did not have reinforced storm shelters, or safe rooms, said Albert Ashwood, director of the Oklahoma Department of Emergency Management. More than 100 schools across the state do have safe rooms, he said.

He added that a shelter would not necessarily have saved more lives at Plaza Towers.

Officials were still trying to account for a handful of children not found at the school who may have gone home early with their parents, Bird said Tuesday. President Barack Obama pledged to provide federal help and mourned the death of young children who were killed while ‘‘trying to take shelter in the safest place they knew — their school.’’ Moore has been one of the fastest-growing suburbs of Oklahoma City, attracting middle-income families and young couples looking for stable schools and affordable housing.

Many residents commute to jobs in Oklahoma City or to nearby Tinker Air Force Base.

THE 10 DEADLIEST TORNADOS IN US HISTORY

A powerful tornado devastated the Oklahoma City suburb of Moore on Monday, killing 24 people, including nine children, according to the Oklahoma medical examiner's office. At one point, as many as 91 were feared dead, but authorities have since scaled back the official death toll.

Here are the 10 deadliest tornados in U.S. history:

1. March 18, 1925 - Missouri/Illinois/Indiana - 695 dead

2. May 6, 1840 - Natchez, Mississippi - 317 dead

3. May 27, 1896 - St. Louis - 255 dead

4. April 5, 1936 - Tupelo, Mississippi - 216 dead

5. April 6, 1936 - Gainesville, Georgia - 203 dead

6. April 9, 1947 - Woodward, Oklahoma - 181 dead

7. May 22, 2011 - Joplin, Missouri - 158 dead

8. April 24, 1908 - Amite, Louisiana/Purvis, Mississippi - 143 dead

9. June 12, 1899 - New Richmond, Wisconsin - 117 dead

10. June 3, 1953 - Flint, Michigan - 115 dead

NOTE: These figures do not include a series of tornados in the southeastern United States in April 2011 that killed at least 346 people in seven states. However, some of the early events on this list, recorded before the era of comprehensive damage surveys, may have resulted from multiple tornados. Death counts for events in the 1800s and early 1900s should be treated as estimates.
