OKLAHOMA CITY (AP) -- At least nine people have been injured following an outbreak of violent weather in the Midwest. A big weather system spawned five tornadoes Thursday, three in Oklahoma and two more in Arkansas. A National Weather Service meteorologist says a tornado touched down after dark in the Tulsa suburb of Broken Arrow. The extent of damage is unclear.
OKLAHOMA CITY (AP) — At least two tornadoes touched down in Oklahoma and another hit Arkansas on Thursday as a powerful storm system moved through the middle of the country. At least nine injuries were reported.
The National Weather Service reported two tornadoes on the ground near Perkins and Ripley in north central Oklahoma and another west of Oden, Ark.
Seven people were injured in tornadoes in Arkansas. Two other injuries were attributed to lightning strikes in that state. Lightning was also believed to have started a fire at a residential complex in northwestern Indiana.
Arkansas Emergency Management spokesman Tommy Jackson said first responders were having trouble reaching a destroyed home where one person was hurt in a tornado because a number of trees were blocking the road. Montgomery County sheriff's spokeswoman Brandy Wingfield said there was property damage, including downed power lines, in the area.
Perkins Emergency Management Director Travis Majors said there were no injuries or damage there. Ripley, about 10 miles east of Perkins, did not seem to have significant damage. The Payne County emergency management director did not immediately return a phone call seeking comment.
Thursday's tornadoes were much less dangerous than the EF5 storm that struck Moore, Okla., on May 20 and killed 24 along its 17-mile path. The U.S. averages more than 1,200 tornadoes a year, but top-of-the-scale storms like the one in Moore — with winds over 200 mph — happen only about once per year. The tornado last week was the nation's first EF5 since 2011.
Some strong winds blew through Moore, in suburban Oklahoma City, on Thursday, but the weather didn't cause significant problems for crews cleaning up from last week's tornado.
This spring's tornado season got a late start, with unusually cool weather keeping funnel clouds at bay until mid-May. The season usually starts in March and then ramps up for the next couple of months.
The Storm Prediction Center in Norman, Okla., warned that there was a moderate risk of severe weather Thursday over much of eastern and central Oklahoma, with storms also possible in the rest of the central United States from Texas to Wisconsin. Flooding is also a concern in parts of Missouri, Iowa and Illinois through Sunday.
In addition to tornadoes, the storms were bringing rain and hail.
"Right now we've been getting a few thunderstorms, but they're very severe supercell thunderstorms," said Michael Scotten, a meteorologist with the National Weather Services. "The whole storm rotates, and they produce on occasion some tornadoes and heavy hail."
The severe weather threat led organizers to postpone the start of the outdoor Wakarusa Music Festival near Ozark, Ark., which will feature Widespread Panic, The Black Crowes and the rapper Snoop Lion (formerly known as Snoop Dogg). An estimated 15,000 sought shelter from lightning and wind Thursday, according to the Times Record newspaper of Fort Smith, Ark.
Of the 60 EF5 tornadoes since 1950, Oklahoma and Alabama have been struck the most, seven times each. More than half of these top-of-the-scale twisters have occurred in just five states: Alabama, Iowa, Kansas, Oklahoma and Texas.
