"When lightning strikes are detected within 5 miles of the airport, it’s our responsibility to notify our partners, who then determine how to move forward based on their own internal policies. Many choose to suspend operations on the airfield... We’ve had lightning within 5 miles of the airport for the last two hours—which is fairly unusual. Operations can return to normal after we have gone 15 minutes without a lightning strike within 5 miles," the airports statement read.
