St. Louis tornado rated an EF-4


A violent EF-4 tornado ripped through St. Louis near 8pm local time Friday night, carving a 22-mile path of destruction up to 0.4 miles wide, and severely damaging Lambert International Airport. The airport, the world's 30th busiest, was closed much of the weekend, but has now re-opened. The tornado, rated an EF-2 when it hit the airport, ripped off the roof from Concourse C, blew out more than half of the windows in the main terminal, and moved an aircraft that was parked at a gate twenty feet. The tornado also passed over a residential area just west of the airport in the community of Bridgton, causing severe EF-4 damage, according to the National Weather Service office in St. Louis. This was the first violent EF-4 tornado of the year.
