Saturday at the AT&T National at Congressional Golf Course will be a silent affair, despite the fact that Tiger Woods is in the hunt for the second straight tournament. Fans have been banned from the grounds.

An enormous storm, with thunder, lightning and winds from 70-80 miles per hour ripped through the Washington, DC area last night, workers arrived at Congressional this morning to find it in ruins.

The storm knocked out power to 400,000 residents around the course and wreaked havoc within the grounds.

The damage is so extensive that the third round has been suspended, with hopes of starting at about 1p.m. ET, in order to give crews time to clean the course.

Initial estimates were that 40 trees on the grounds were uprooted including a 75-foot tall tree that was lying across the 14th fairway when crews arrived. The rest of the course is sprinkled with downed branches and leaves. The debris is so thick in some cases that it makes the holes unplayable.

Due to safety concerns, only security staff, tournament, officials, workers and media would be allowed on the course. The only fans in attendance will be the families of players.

The PGA has announced that tickets for Saturday would be honored on Sunday. If, and how much this might delay the end of the tournament on Sunday is unclear. The PGA makes every effort to get tournaments finished on Sundays as ratings, and spectator numbers plummet on Monday when everyone gets back to work.

Hunter Mahan leads the AT&T National with a (-7) through the first two days. He is two shots clear of Robert Garrigus, Jimmy Walker, and Brendon de Jonge. Woods is tied for 11th at (-2).
