Morning everyone, and welcome to live coverage of final free practice session ahead of qualifying for the Belgian Grand Prix. After the majority of Friday's running was carried out in the wet, you may be surprised to know that it's actually dry at the moment, although it's much cooler than yesterday and rain is expected.

The biggest talking point in the paddock surrounds Mark Webber this morning. After setting the fastest time yesterday Red Bull has confirmed that he has signed a new one-year contract with the team for 2012.

If you've got a view on Webber's new deal, or on anything else remotely to do with Formula One, then let us hear it by emailing us using the link above, or via Twitter @ESPNF1_live.

@TheFria on Twitter says: "Another season playing 2nd fiddle to Vettel? Webber is a way better driver than that"

We've got Laurence gathering all the news and views in the paddock this weekend, and he thinks Nick Heidfeld has done little wrong: @EdmonsonESPNF1 "Followed Heidfeld into the circuit. His driving looked pretty good to me, although he didn't let me in to a queue at a junction."

Rain is in the air, although yet to start falling. While qualifying is forecast to be wet, the teams really want some dry running as the current forecast for the race says we will have a dry grand prix.

Mercedes (OfficialMGP) on Twitter: "10 minutes to FP3 and it just started raining. Perfect timing!"

Some great images being shown of John Surtees posing with Felipe Massa and Fernando Alonso. Always good to see ex-world champions in the paddock.

It's definitely raining now, and the track has turned a darker shade of grey. It will be intermediate conditions when the light at the end of the pit lane goes green.

Not only has Mark Webber signed a new deal, it's also his birthday. He's 35 today, so will be looking for a birthday present in the form of pole position later today. Anybody else adding another year to the total this weekend?

McLaren (TheFifthDriver) on Twitter: "Here's a weather update - it's lightly raining but forecast to get worse."

The session is underway, with d'Ambrosio and Perez straight out on track. They're joined by Alguersuari and di Resta.

The track is very wet in sector two. A lot of standing water and the extreme wet is the way to go if drivers are going to do any running.

Schumacher is being followed by Vettel, and the standing water increases as soon as they turn left in turn nine. McLaren and Ricciardo the only cars not to have gone out so far.

Hamilton is out on track now, sensibly on full wet tyres. Even that is barely helping him, as the car is aquaplaning a lot in a straight line. "Massively wet" he says over the radio.

Button is out on track too now, the only one out there as Hamilton returns to the pit.

Button asks for another suit, gloves and boots over the radio as he tip-toes around the track. He'll be soaked.

Button makes it back to the pit lane without any further drama. The rain is falling very heavily still - again we've long since passed red flag conditions. Button confirms that on team radio saying "The rest of the circuit is red flag. It's worse than we had in Canada"

There are a number of rivers running across the circuit, and you'd have to be a very brave man to head out on track right now.

A quarter of the way through the session and we have no more than one lap per driver. Michael Schumacher is in the garage talking to an engineer, as nobody shows any sign of going out again.

Martin Whitmarsh admits to the BBC that the track is unlikely to dry out enough to see any substantial running in this session.

Force India (ClubForce) on Twitter: "Radar shows that the rain could be with us for the entire session. Classic Spa weather once again."

Satyajeet: "I see that recently the f1 cars haven't been able to cope with rainfalls as well as they were in the 90's and till 2006... am i correct...because i've seen some gr8 races in very bad rain."

I wouldn't say it's necessarily that cut and dried Satyajeet - we've seen some ridiculously heavy rain in recent years, but the attitude has changed slightly as drivers asked the FIA to prevent accidents by deploying the safety car or red flagging races rather than waiting for one to happen first. As a more direct comparison though, the conditions 10 minutes ago were worse than when Schumacher ran in to the back of Coulthard in 1998.

Daniel Ricciardo is on track to carry out his installation lap. He's on full wets but it does look a bit brighter out there...

Alguersuari heads back out, carrying out a practice start at the pit lane exit before heading down to Eau Rouge.

Alguersuari is on full wet tyres, but still very twitchy in sector two. He's able to go quicker than anyone has been before today though, so conditions have improved a little.

Buemi and Vettel join the track too, as Alguersuari begins a flying lap. I say flying...

Barrichello and Maldonado have also gone out for Williams

Alguersuari sets the first lap time, a 2:30.210 after backing off in the middle sector. Buemi beats it with a 2:14.207

The track is a lot busier now, as Vettel completes a 2:15.082

We had a long yellow flag period then, but were never shown anyone off track. The timing screen says that Bruno Senna went off at Les Combes and continued, with replays showing him doing exactly that.

Webber goes quickest with a 2:14.143, 0.029s quicker than Buemi.

Only Vettel, Schumacher, Barrichello, Hamilton and Button in the pits at the moment.

The lap times are representative of what we were seeing in the middle of FP1 yesterday, and with the sun out the track is beginning to dry, but the spray is still a big problem.

Di Resta has gone off at Pouhon but is able to rejoin. He ran wide on to the kerbs and spun.

Di Resta is still trying to find confidence around this track having not raced here since 2005. He was pushing hard through Eau Rouge and had a moment before going off at Les Combes and then spinning later in the lap.

Buemi's gone quickest with a 2:13.306. Alguersuari 0.051s further back with Sutil third.

The sun has disappeared again, and it looks a bit darker out there...

Sutil goes quickest with a 2:13.231.

Buemi says it is too wet for inters right now on the radio, but then both Mercedes put on intermediates and head out.

Di Resta goes quickest with a 2:12.955.

Schumacher is really wrestling with the car through turns eight and nine, the back end stepping out as he tries to ease in the power.

The only two cars yet to go out again after their installation laps? Hamilton and Button at McLaren

Schumacher goes second, 0.244s off di Resta's time.

Alguersuari goes comfortably quickest with a 2:11.045, we think on full wets.

Button and Vettel head out on intermediates

Buemi now fastest, a 2:10.580, and that's on the intermediate tyre

Alonso goes out on full wets, while Hamilton is on inters

Rosberg has a front right puncture, which is confirmed to him on the radio.

Times dropping now on intermediate tyres, Alguersuari quickest in 2:09.948

Yuvraj asks: "Clearly, Lewis (and perhaps Kobayashi earlier in the season) makes the races more fun to watch than most. Why is it then that he faces most criticism in comparison?"

It's the nature of the beast, Yuvraj. He is entertaining because he pushes his car to the limit and takes more risks than many in terms of overtaking, which obviously can annoy those on the receiving end and also heighten the chances of mistakes or accidents.

Button goes second. Still 0.3s slower than Alguersuari

Webber goes quickest, a 2:08.988.

Button was on a quick lap but is told to back off if he has learnt all he wanted to in order to save tyres.

Vettel now fourth quickest, Hamilton goes fifth.

Rosberg is back out after replacing that punctured tyre. He's quickest in sector one as well

Only two cars are yet to set a lap time, the Ferrari pair of Massa and Alonso. Alonso is in the pits but Massa is on track

Rosberg goes seventh quickest as Hamilton improves in sector one

Button has come back out to do a practice start. He had previously only completed one run to set the third best time.

The hour is up, and Hamilton ends the session with a quick lap to go second, just 0.058s slower than Webber.

Massa did do a time late on, a 2m22s putting him comfortably last, but that's better than his team-mate Alonso managed.

So, noteable pace in the wet coming from Alguersuari in third, Buemi in sixth, Senna in ninth ahead of Michael Schumacher and Kovalainen in 12th. But at the top it's the same man as yesterday, birthday boy Mark Webber tops the timesheets once again.

The track is still very wet and is unlikely to dry in time for qualifying. More rain is forecast, and that's going to make qualifying very interesting indeed. We could see a mixed up grid and a few mistakes as drivers push harder in the wet, while being on the right tyre at the right time will be crucial. Excited? I am. Join us again in 90 minutes.
