Play is scheduled to begin at 17:00 BST with groups of three in a split-tee start, although rain continued to fall.
A few players began their rounds early on Sunday before play was halted at 13.15 BST, but those scores will be erased, organisers said.
Spain's Sergio Garcia, on 13 under par, held a one-stroke overnight lead over American Roberto Castro and Swede Henrik Stenson. Those three players are scheduled to tee-off at 19:00 BST.
