"They're in my thoughts and prayers", she said.First-round leader Feng rolled in three birdies in her bogey free round, while defending champion Cristie Kerr had a 75 to reach two-over 146, six shots back of Henderson.Hawaii native Michelle Wie shot a 73 and is tied for 31st. Henderson and sixth-ranked Ariya Jutanugarn (69) were the only other golfers to break 70 on a day that featured rain squalls and winds gusting to 30 miles per hour.
"I feel like I'm in a great spot obviously at the top", said Henderson, who has held the 36-hole lead during four of her five career LPGA wins, including at the 2016 KPMG Women's PGA Championship.
Henderson finished the day at nine under par, one shot clear of American Mo Martin, who shot a 72, and two shots ahead of Japan's Nasa Hataoka and South Korean Inbee Park in third place. She insists she "gets more excited" in the wind, which should make Ko Olina an ideal site for her this week.
The Chinese star finished at 5-under 67 at Ko Olina Golf Club. "Just being able to adjust to it, kind of stay poised in it. Things aren't going to always go perfectly, but I felt like my ball striking was probably the best it's ever been". She drained a 10-footer for another birdie on the 16th, where she four-putted Friday.
"I didn't play bad, but I think I missed about three to four putts that were less than 1 meter long", Park said after the round.
Also still in with a shout are the likes of Lizette Salas and World No 1 Shanshan Feng, who both lie just three strokes back after rounds of 71 and 70 respectively. She started with a birdie but alternated bogeys and birdies on the third to sixth holes.
