An EF4 tornado struck near St. Louis, Missouri Friday night, forcing the closure of Lambert-St. Louis International Airport and damaging over 2,700 buildings in St. Louis County. The National Weather Service also confirmed that an EF1 tornado touched down in neighboring St. Charles County and an EF2 touched down in Pontoon Beach, Illinois.

The city of Bridgeton, in North St. Louis County, was hit by the EF4 tornado. According to the National Weather Service, it was the most powerful tornado to touch down in the St. Louis region since 1967, with winds ranging from 166 and 200 miles (267 and 322 kilometres) per hour. Aftereffects of that tornado were also reported in Maryland Heights, Missouri.

One official estimated that anywhere from 50 to 200 homes in the Maryland Heights and Bridgeton areas incurred damage, but early numbers released by St. Louis County indicate that over 2,000 buildings in those two cities had suffered “noticeable damage,” which does not include minor damage. Around 30,000 people in the region did not have power Saturday, out of a total of 47,000 affected residents.

Authorities with search and rescue dogs went door-to-door Saturday, looking for possibly trapped residents. Aerial imagery was being used in damage assessment. Area residents unaffected by the tornado were assisting those that lost their homes, reported St. Louis television station KSDK.

The Harmann Estates neighborhood of Bridgeton was heavily damaged during the storm, with many residences losing roofs and siding. Officials have already condemned some of the subdivision’s homes. St. Louis County Executive Charlie Dooley reported 25 homes in Bridgeton and Berkeley, Missouri as being completely destroyed and an additional 35 as uninhabitable.

Granite City, Illinois was struck by the EF2 tornado, while New Melle, Missouri was hit by the EF1. Fourteen New Melle homes sustained minor damage, while four were heavily damaged.

The storm also caused the temporary shutdown of two major St. Louis highways. Portions of Interstate 70 and Interstate 270 were closed Friday night due to fallen power lines and storm debris. Both blocked sections have since reopened, but officials said it would take a few days to remove all the debris, which they pushed onto the roadsides.

Lambert-St. Louis International Airport, which is immediately west of Berkeley, suffered heavy damage Friday night from the same tornado, and was forced to halt all regular operations Saturday while crews worked to clear the affected terminals. Eight flights had been forced to land in Kansas City, Missouri Friday night due to the tornado. About 500 people were in Lambert Airport when the tornado hit. A Federal Aviation Administration (FAA) spokesperson said other US airports were not affected by Lambert’s shutdown. Lambert is not an airline hub and is significantly less busy than it was ten years ago.

In a Saturday press conference, Rhonda Hamm-Niebruegge, Lambert’s director, said the airfield and Terminal 2 were “fully functional,” but the main terminal’s Concourse C had been severely impacted by the storm. That terminal, which sustained the heaviest damage, serves Air Tran, American Airlines, Cape Air, and Frontier Airlines. The total cost of repairs at Lambert is expected to be in the millions of dollars, but Hamm-Niebruegge said the airport does not yet have a good estimate.

One passenger of a waiting plane at Lambert told KSDK that heavy winds pushed the aircraft about 20 feet (6.1 metres) while it was still attached to the gate. Two other planes on the tarmac were unable to return to the airport, so passengers were bused back. Five planes—four operated by American and one by Southwest Airlines—suffered damage, and some will undergo major repairs.

Some travelers inside the airport received medical attention for minor injuries caused by flying glass. A handful of people were transported to a local hospital for additional treatment, but all were later released. “We get to the terminal and lights were out, glass everywhere, blood everywhere from people had been cut,” recalled one witness. Another person at the airport reported, “The ceiling was falling. The glass was hitting us in the face. Hail and rain were coming in. The wind was blowing debris all over the place. It was like being in a horror movie. Grown men were crying.”

On Saturday, it was evident that Concourse C would not be open for some time, said Mayor of St. Louis Francis Slay. A large section of its roof was missing and around half of its windows had been blown out by the high winds. Debris and water from the storm were present inside the airport as crews worked to restore power and assess damage to the terminal. Missing windows had been boarded up, ruined carpet had been removed, and the control tower was functional by Saturday afternoon. The power was back on by 7:40 p.m. CDT (00:40 UTC) that evening.

The airport resumed outgoing flight services Sunday, although several incoming flights landed at Lambert Saturday evening. Slay said the airport will be running at 70 percent capacity until mid-week, depending on the availability of airline crew members and planes. Airlines using Concourse C will have their operations temporarily relocated, he added. On Sunday, Southwest was operating at normal capacity, while AirTran moved to Concourse B and canceled four of its eleven scheduled flights. A spokesperson for American said the airline would have planes ready for normal Monday operations. American had previously canceled all St. Louis flights scheduled for Sunday.

On Saturday afternoon, Missouri Governor Jay Nixon arrived at Lambert and visited areas devastated by the tornado. He originally planned to tour Maryland Heights, Bridgeton, and Berkeley, but Nixon was only able to tour Berkeley due to an approaching line of storms. While in St. Louis, the governor said 750 Missouri homes had been damaged by Friday’s tornadoes and that federal assistance was forthcoming. Nixon reported that the Federal Emergency Management Agency (FEMA) was involved in assessing storm damage, as well as that US President Barack Obama had already contacted him, promising relief funds. US Representative Lacy Clay, said Saturday that he would brief Obama on the situation.

The state declared the affected areas of St. Louis County a disaster area. No one has reported serious injuries or deaths as a result of the storm, although some people were treated for minor injuries. “It was horrific and for that much damage to been done, to have no loss of life, is truly a blessing,” Slay said.
