Just before noon Friday, lightning struck the Wynnewood Oil Refinery in Garvin county.       Officials say it hit a large storage tank holding 25,000 barrels of light oil, sparking a large explosion. KTEN's Andrea Kurys was on the scene.    

Oklahoma Highway Patrol officials say two storms hit Wynnewood in less than an hour. Though they were small, they both produced giant lightning bolts.     

The explosion blew the roof of the barrel sky-high. Smoke could be seen for miles away. Luckily though, no one was injured.

An emergency response team from the refinery was immediately on scene, as well as OHP officials, the Wynnewood police and fire departments and the Garvin County Sheriff's office. The oil fire was contained in under an hour, but continued to burn all day.

Everyone at the refinery was evacuated as a precaution. OHP Trooper Doug George"We've currently shut down this portion of US 77. Of course, it includes the entire refinery section here from any though traffic. Only traffic coming out of the refinery are emergency crews going into the refinery."     

Twelve hours later, highways were still shut down. Officials were in the process of using a thermal imaging device to detect any hot spots.     

It turns out no one had to be evacuated from the town of Wynnewood, though crews were on stand-by in case the fire got out of hand.
