Energy workers at oil and gas drilling sites and those at wind farms in Oklahoma dodged severe weather on Monday as a massive storm system produced up to 15 tornadoes.
A large twister struck near Mangum in the southwest and caused damage to some homes, but no injuries were reported.
Funnels were sighted near Clinton and sirens sounded in some of the western cities and towns. Several tornadoes were reported south of Perry and one home suffered extensive damage. The residents were not home at the time and escaped injury.
Heavy rains resulted in flooded streets and high-water rescues in the city of Enid.
Tornadoes struck late Monday night in eastern Oklahoma, destroying a business in the small town of Peggs in Cherokee County. Again, no one was hurt. A tornado also reportedly made a direct hit on the community of Leach in Delaware county.
Then as the third round of the storm system moved across Oklahoma early Tuesday morning, it dumped huge amounts of rain. Heavy flooding forced a closure of Interstate 40 and Radio Road in El Reno, a location for several major oilfield offices and centers. Both east and westbound lanes were flooded early Tuesday morning.
Flooding also shut down part of the turnpike near Luther. The system then produced tornadoes in Hughes County as well as in Tulsa.
Sirens sounded in Tulsa around 6 a.m. on Tuesday and KOTV meteorologist Alan Crone said there were indications the tornado touched down several times as it moved eastward.
