Weather officials say the tornado that touched down in western Pennsylvania on Thursday was an EF-1 packing wind gusts up to 105 mph.
The National Weather Service also says the tornado that touched down in Uniontown at about 6:45 p.m. Thursday was the first tornado to strike the region in February since 1950.
The Uniontown emergency management agency said after an initial assessment that 20 to 25 buildings had significant damage after the tornado, which traveled for two miles. Several businesses were also damaged.
Emergency management coordinator Greg Crossley says officials are trying to determine whether the damage will qualify for Small Business Administration loans, which require at least 25 properties with 40 percent or more uninsured loss.
Power has been restored to many of the 3,000 homes and businesses affected.
