Organizers twice halted play due to weather conditions. Lightning led to a 3-hour delay just after noon and suspended play for the day about 4:15 p.m. when threatening weather returned.
The first round is to resume Friday morning followed by the second round for the 30-player field.
Donald was 3-under in the first two holes, finishing off an eagle at the 589-yard, par-5 second hole. He added birdies at Nos. 8 and 9 but was called off the course after 11 holes.
