A surprise EF-2 tornado ripped through Tulsa, Oklahoma early Sunday, August 6, 2017, destroying buildings and injuring 26 people, two of them severely. The National Weather Service confirmed two EF-1 tornadoes in towns nearby. Tornadoes in August are uncommon, but not ‘outrageously rare,’ NWS said.
