Survey teams in northeastern Oklahoma now say the area was hit by at least four tornadoes during a round of weekend storms that hammered a number of businesses in Tulsa.

Forecasters say they confirmed a fourth storm track near Chelsea, about 40 miles (64 kilometers) northeast of Tulsa. Other storms hit at Broken Arrow and Oologah early Sunday morning.

The Chelsea storm was rated EF-1 on a scale of tornado damage, with winds between 86 and 110 mph. An EF-2 storm wind winds up to 135 mph hit Tulsa's midtown section, causing so much damage that city officials condemned 10 businesses. A home was also destroyed, and about 200 homes and businesses were damaged.

About 30 people were injured in Tulsa, but no other injuries were reported in storms farther away from the city.
