Winds gusting over 40mph caused play to be suspended during the second round of The Open Championship at St Andrews.
The wind was strong enough to cause balls to move on the more exposed greens of the Old Course, with officials halting play shortly before 2:40pm.
R&A rules secretary David Rickman said: "A number of greens just became unplayable. We had problems at the 12th, 13th, tenth, 11th and seventh, those out at the far end near the estuary.
"The odd ball oscillating happens, the odd ball moving happens, but when you have a series of incidents in close succession that's the time when play is just not possible."
The suspension was possibly good news for Northern Ireland's Rory McIlroy, who was on the fourth fairway when the hooter sounded.
McIlroy had enjoyed a two shot overnight lead after taking full advantage of the near-perfect conditions available to Thursday's early starters, equalling the lowest round in Major Championship history with a stunning 63.
But by the time he teed off this afternoon, the 21 year old found himself three off the lead and the blustery wind was picking up.
South African Louis Oosthuizen, second overnight, had added a 67 to his opening 65 to set a testing clubhouse target of 12 under par, equalling The Open Championship record in relation to par established by Nick Faldo and Greg Norman in 1990.
McIlroy began confidently enough, opening with three pars to remain nine under and outright second, with 1989 winner Mark Calcavecchia alone in third place on seven under, the 50 year old having completed a flawless 67 in the first match out at 6:30am.
