The first qualifying session of the 2013 Formula 1 season was delayed by torrential rain at the Albert Park circuit in Melbourne, Australia.
The drivers managed to complete Q1, with Pastor Maldonado, Esteban Gutierrez, Jules Bianchi, Max Chilton, Giedo van der Garde and Charles Pic all bowing out.
Nico Rosberg took P1, but could struggle to replicate that pace in Q2 and Q3 tomorrow with dry weather expected.
You can read how the rain-swept session unfolded below.
5.31amThe biggest and best motorsport championship is back! The drivers return to Melbourne for the traditional beginning of the 2013 Formula 1 season.
5.33amIt's the first qualifying session of the season. However, the rain is pouring Down Under and that has caused some problems for the drivers and television crew alike!
5.34amWorld champion Sebastian Vettel went quickest in the first two practice sessions yesterday, but an electronic problem with his car forced him off before the end of this morning's session.
5.36amThat allowed Romain Grosjean to finish top of the pile this morning. Meanwhile, the TV crews have experienced intermittent blackouts, meaning that at any moment we could suffer a break in coverage. You have been warned!
5.38amThe rain is great news for one man in particular - Fernando Alonso. The Spaniard is an expert in wet conditions, as is McLaren's Jenson Button. The British team have struggled for pace so far this weekend, so the weather really could help Button catapult himself up the grid. But he needs the car to do so, so we'll see...
5.41amButton loves the Albert Park circuit as well. He has won here three times, including last year, when he overtook then-teammate and pole-sitter Lewis Hamilton.
5.43amHe has a new teammate this year in the impressive Sergio Perez. The Mexican had a marvellous campaign last year so it will be interesting to see how he handles in his new car.
5.45amIncidentally, should Button triumph this weekend he can join a small club of four-time winners of this Grand Prix. He'll be keeping great company alongside Lex Davison and Michael Schumacher. Although it looks unlikely he will do so...
5.51amWe're just under 10 minutes from the start of qualifying now and the rain is still lashing down. Quite unlike Australia, especially for this time of the year (it's their summer). It's gearing up to be a very interesting session indeed.
6.19amIt looks like we will be getting underway soon. With the safety car going round the track once more we'll soon be finding out.
6.20amNope, it's another 10-minute delay. How frustrating...
6.23amThe drivers all look extremely focused during this agonsising delay, but they'll no doubt be desperate to get underway. This can't be helping the rookies, who will be suffering from a few butterflies already.
6.26amHamilton is out of hick cockpit and having a stroll. Not much else happening at the moment...
6.29amHamilton and Rosberg have made their way to the front of the pit lane. They've been joined by Gutierrez and it looks like we'll be starting. Hurrah!
Q1The drivers are, of course, on full wet tyres. There's plenty of spray up, making slip streaming difficult.
Q1Van der Garde has gone off and totalled his front wing. Not the best start for the rookie then...
Q1Hamilton clocks 1.50, but his teammates Rosberg comes round two seconds quicker.
Q1Hamilton has stopped by the side of the track! The type of tyres means that he cannot get forward traction and he's beached the car. He bends the rules by reversing and he's back on the track, but it will be interesting to see what the stewards do about that. Reversing is a bit of a no no...
7.06amIt's 6.06pm local time and the darkness is starting to set in around Melbourne. We hope to be getting underway with Q2 in the next few minutes.
7.09amBREAKING! Q2 will not get underway before 7.30am (UK time).
7.11amPastor Maldonado: "The car is undriveable at the moment and we need to work."
7.13amA "very heavy shower" has been predicted imminently, which is why there has been a 20-minute delay imposed.
7.18amReports suggest that we should have around another hour of race-able light. If there's no conclusion today then it'll happen before the race tomorrow.
7.19amThe problem seems to be the white lines on the track, being that this is a street circuit it's unavoidable. Plenty of drivers spun off in Q1, but fortunately no injuries. Except to the cars. Poor cars.
7.26amWe're still not sure if we'll be getting underway. The heavy shower that has been predicted could mean that we won't get done today.
7.43amStill no word on whether we'll get underway soon. Another delay would surely mean that we'll be back early tomorrow.
7.45amTed Kravitz reporting on Sky Sports that the weather does not look good at all. The wind is proving to be a particular problem now, but it looks like we could at least start Q2. Whether we finish is still anyone's guess...
7.46amThe drivers are getting strapped into their cars, though. At least some signs for optimism.
7.48amBREAKING! Q2 and Q3 has been postponed until tomorrow morning.
7.49amWell that's that then. The weather has put paid to today's qualifying. We will have to wait until tomorrow to see who will start on pole for the Australian Grand Prix.
7.51amSo join us tomorrow from midnight for Q2 and Q3. The race will get underway at the scheduled time of 6am. So it shouldn't really matter too much. Let's hope for dry weather!
