More than two and a half hours was lost Saturday at the Crans-sur-Sierre course in Switzerland when heavy fog blanketed the area and made play impossible.
Cold conditions made scoring difficult when play resumed shortly after 5pm and Hend wasn’t the only player to struggle.
At 11-under he leads by two, Matthew Fitzpatrick, Darren Fichardt and Fabrizio Zanotti his nearest challengers at 9-under.
Hend’s Olympic teammate Marcus Fraser is part of a six-way tie for fifth at 8-under after completing a 4-under 66 which included four birdies, an eagle and two bogeys while Ryan Fox and Todd Sinnott are both at 7-under through 14 holes.
After starting the day with a two shot lead Hend increased his advantage with a birdie at the first but play was halted one hole later as thick fog blanketed the course.
Two hours and 36 minutes later play resumed but conditions had changed markedly from what the field faced in perfect weather over the opening two days.
"It was all calm when we started but after we went back, it was just so cold out there," said Hend after play was called due to darkness.
"The greens got a little bit rough so I was just trying to be patient. Everyone was dropping shots.
"Some nice holes to finish with when we come back tomorrow so we will see how we will be positioned for the final round.
“I will just come back here tomorrow and play like how I have played all week. Hopefully it's good enough. We will see what happens.”
Hend lost this tournament in extra time to Alex Noren last year when the Swede birdied the first play-off hole.
Despite the distraction of his children being at home in Florida with Hurricane Irma approaching Hend, with wife Leanne on the bag, has played some inspired golf.
He will be one of 12 players with holes to complete when play resumes Sunday morning.
Brett Rumford (T54), Sam Brazel (T58), Jason Scrivener (T67) and Nathan Holman (T75) were the other Australians to make the cut.
