Qualifying for the season-opener Australian Grand Prix will be postponed until 11.00 am local time on Sunday morning due to heavy rain showers in Melbourne.
A delayed Q1 managed to take place after thirty minutes, but the start of Q2 was repeatedly put back due to the weather conditions.
The decision to postpone the rest of the session was finally taken nearly two hours after qualifying had begun.
The situation was complicated by further showers being forecast, so that even if the track improved, the likelihood was that the rain would immediately return.
Fading light added a further pressure to fit in Q2 and Q3.
Before the postponement was announced the FIA race director Charlie Whiting said: “After Q1 there was a lot of debris to pick up off the track plus the fact it had rained a little heavier. So we want to try to clear as much water off the track as possible. So we think a twenty minute delay is what we need.”
“The guys are out there working really hard to clear the water off the track. We do have the prospect of another quite heavy shower between now and half past six so I’m not sure that we’ll be able to start at half past six but we’ll do the best we can.”
As for the track action, Nico Rosberg went quickest in Q1. The Mercedes team timed the moment right to get both cars out at the start of the session.
This meant Rosberg spent a long while on top, although he had to fight to get the position back again after everyone switched to intermediates with five minutes to go.
His team-mate Lewis Hamilton spun at Turn 2, sustaining minor rear wing damage as he nudged the barriers. Briefly stranded on the sodden grass, he eventually managed to reverse back onto the track.
That was one of many incidents during the running that did take place.
Felipe Massa and both Caterhams had to limp back to the pits minus front wings after spinning into the barriers.
Esteban Gutierrez had a similar incident but ended up stranded on track in a damaged Sauber. That left him P18 on the grid, just behind a frustrated Pastor Maldonado.
Jules Bianchi led the rest of the rear pack in his Marussia, with the crashing Caterhams at the very back.
