Play has been suspended at the Kuala Lumpar Golf and Country Club midway through the second round of the Malaysian Open due to a risk of lightning.
Storm clouds have begun to gather in the area, forcing organisers to stop play on the course, which has left Otto Hennie and Jbe Kruger in the lead with a nine-under-par advantage.
Louis Oosthuizen, who failed to clinch the Masters last weekend after a play-off tie with Bubba Watson, left the course on two-under, with the remainder of the second round left to play.
Meanwhile, former owner of the coveted green jacket Charl Schwartzel relinquished his lead at the top by dropping three shots on the green before organisers halted play.
