"We've had much worse than this, we lost Thursday in its entirety a few years ago and some of Friday and still finished 72 holes by 4pm on Sunday.
"There's no thought of it being reduced to 54 holes at this stage."
Officials sounded the siren to halt play on Thursday at the first sign of thunder and lightning.
American Boo Weekley, who finished his round earlier in the day, is the clubhouse leader after scoring a six-under par 66.
He leads by two shots from a group of players on four-under including defending champion Adam Scott and New Zealand's David Smail.
Fellow New Zealanders Ryan Fox, Josh Geary and Michael Hendry were all at two-under.
Langford-Jones said if play is unable to resume on Thursday, those players yet to complete their rounds will do so first thing on Friday morning before the second round gets underway.
