None of the leading players were able to start their third rounds with South Korea's Na Yeon Choi still leading the field.
She dealt well with windy conditions on Friday to card a second consecutive 67 to finish 10 under par, one shot ahead of Japan's Miki Saiki with American Morgan Pressel another stroke back.
But with the troublesome wind stronger today than earlier in the week play was suspended shortly after 6pm, with the third round due to resume tomorrow at the earlier time of 6:15am.
Although the earlier start gives the organisers a chance to get the tournament finished on Sunday, Ladies' Golf Union head of operations Susan Simpson conceded the weather could still force play in to Monday.
"It's still going to be windy tomorrow," she said.
"Not hopefully as windy as it's been today, but there's no let-up in it. So tomorrow morning, it's still going to be very breezy and equally difficult conditions.
"This is a major championship and every endeavor will be made to finish 72 holes. So if we need to go to Monday, then we'll go to Monday."
