Heavy rain and storms associated with Typhoon Kong-rey washed out the third round of the LPGA's Japan tournament on Saturday, reducing competition to 54 holes.
The LPGA said the tournament was scheduled to be completed on Sunday at Seta Golf Course.
The tropical storm has most seriously affected the Philippines and Taiwan. In Taiwan, it brought heavy winds and flooding, resulting in two deaths.
Hana Wakimoto shot a four-under 68 on Friday to maintain her lead after the second round. The Japanese player shot 63 in the opening round and had a 13-under-par total of 131.
American Yealimi Noh and Ariya Jutanugarn of Thailand are two strokes off the lead after the second round. Noh shot 65 and Jutanugarn 66.
Perth 26-year-old Hira Naveed is the leading Australian and is tied eighth.
Naveed fired a bogey-free six-under-par 66 in the second round to surge to eight under and will have to make up five shots to win a maiden title in her rookie LPGA season.
The Japan tournament concludes a four-event Asian swing for the LPGA Tour that included events in China, South Korea and Malaysia.
