Greens were pelted by big hail and debris blew around the TPC Four Seasons course, but the site of this week's Byron Nelson Championship escaped significant damage during heavy storms.
Slugger White, the PGA Tour's vice president of rules and competition, said Wednesday that nearly 1½ inches of rain and hail "half the size of baseballs" fell the previous night.
"There is a lot of debris, leaves, branches," White said, adding that he saw no trees down.
White said it was uncertain to know how the damage and the repair work on the greens would affect the tournament.
"They had guys on there (Wednesday) morning, 10 or 12 guys going from front to back trying to fix what looked like ball marks," he said. "And then they rolled 'em after that and we'll see what it looks like tonight."
The Nelson's pro-am tournament was played Wednesday under sunny skies. The start was delayed an hour because of work being done to the course.
The storms in the Dallas-Fort Worth area Tuesday night included tornado warnings and significant hail. Fans attending the Texas Rangers' game against the Chicago White Sox were evacuated from the stands at one point during a nearly three-hour rain delay before the game was resumed and ended at 1:27 a.m. local time.
Tournament spokeswoman Tracy Cobb said members of the Salesmanship Club, the charitable group that puts on the tournament, were helping rake out bunkers before the pro-am.
