ST. LOUIS—The National Weather Service has determined nine tornadoes touched down in the St. Louis area during Friday night’s storm that damaged hundreds of homes but caused no serious injuries.
The weather service’s Jayson Gosselin says a 1,000-yard-wide twister that hit portions of St. Charles County and portions of north St. Louis County was an EF-3, which has winds between 136 and 165 mph.
Authorities said the tornado went on a 32-mile damage path through the southern and eastern parts of St. Charles into north St. Louis City.
The tornado started in Weldon Spring Heights and moved east through Harvester, Earth City, Bridgeton and Ferguson, before ending in the northern edge of St. Louis City.
Officials say eight people suffered minor injuries during the storms. Authorities said 74 homes in the county sustained enough damage to make them uninhabitable, while more than 100 have slight to moderate damage.
St. Louis city spokeswoman Maggie Crane said four outbuildings at Lambert airport were damaged, and all flights were grounded until the storms cleared.
Another EF-3 tornado reaching speeds of about 140 mph ripped through a landfill in Roxana, Ill. An industrial building there sustained damage.
In Macoupin County, an EF-2 tornado swept across Gillespie, downing power lines and heavily damaging several buildings. The 115-mph winds ripped the roof from the high school gymnasium. Several nearby homes were also damaged by the storms, which brought heavy rain and reports of tornadoes in the town of about 3,400.
The weather service said another EF-1 tornado touched down in Macoupin County about a half-mile south of the intersection of County Road 100 East and 2200 North.
Two EF-1 tornadoes also formed in Franklin and Jefferson counties in Missouri. Officials said there were portions of straight-line wind damage that consisted of mostly downed trees and broken tree limbs.
In Montgomery County, three EF-0 tornadoes touched down in Montgomery County. Two of them were located near Montgomery City and one formed near New Florence. Mostly trees and roofs were damaged from the weak tornadoes, though officials said a branch fell onto an empty school bus.
