So when you send an insane early-summer thunderstorm with 70 mile-an-hour winds whipping through a tree-lined golf course, you get some of the images seen here.

As Barry Svrluga wrote, roughly 40 trees went down during the storm, causing a delay of about six hours before Saturday’s AT&T National third round. Quoting Barry:

Several trees were down at Congressional, both in fairways and in prime spectator areas, with loose limbs causing potentially dangerous situations. The 14th fairway was completely blocked by a fallen tree, and there is debris strewn about the course.

By Saturday morning, Greg McLaughlin, the tournament director, wrote on his Twitter account that the front 9 was “perfectly cleaned up,” but that 75 percent of the damage had occurred on the back 9.

“I think Congressional maintenance can remove a significant dollar amount from its 2013 tree trimming budget,” McLaughlin also wrote.

These images come from McLaughlin, the PGA Tour’s media account, and Comcast SportsNet’s Chick Hernandez. They show the 14th fairway (above and below), and then, in order, No. 17, the No. 4 tee box, the right of No. 3, the course’s digital clubhouse, and the Comcast SportsNet set.

Pretty wicked stuff.
