Rain08:55 Hello everyone and welcome to AUTOSPORT Live for continuing coverage of round 12 in this year's FIA Formula 1 world championship - the Belgian Grand Prix from Spa-Francorchamps.

Yesterday's pair of practice sessions were largely washed out, leaving the teams with just 60 minutes to set-up their cars for the demanding 7.004km Ardennes circuit.

Teams have a lot of work to get through this morning. Both types of Pirelli slick tyre need to be evaluated, as well as perfecting the car set-up and running with both low and high fuel. It promises to be an interesting hour.

Friday's post-practice news centred on Mark Webber, who was handed a five-place grid penalty for a gearbox change. The Australian is Fernando Alonso's closest challenger in the championship and this turn of events could give the Ferrari driver even more breathing space in the points race by the end of this weekend.

Webber gets gearbox change grid penalty

08:56 Weather conditions are a marked contrast to yesterday, as we wait to get going in final practice. The rain has gone and there was a brilliant sunrise over the Wallonia region this morning.

Dry and mainly sunny conditions are expected during today's on-track action. It will remain relatively chilly, however, with air temperature only reaching 15 degrees Celsius during qualifying, while a light breeze will continue from the north.

08:57 Teams will finally get an opportunity to test Pirelli's medium and hard rubber on a dry circuit, but face plenty of challenges in squeezing the tyre evaluation into this final frantic hour of practice.

Grip levels remain low after yesterday's deluge and it is still chilly - with both factors adding to the already high demands on the rubber here.

With just one allocated set of each compound, race engineers will need their drivers to make the most of the running this morning. Limited laps of this lengthy circuit are available to find a balance in the dry - while the track evolves considerably - along with a measure of durability to shape the race strategy.

08:57 Track temperature is up to 20 degrees, as we approach the start of this important 60-minute session.

08:59 Drivers are gearing up for a busy hour, with plenty work ahead to evaluate the medium and hard compound tyres this morning.

16 min: Glock moves up further to second fastest in 1m54.185s as Marussia perhaps look towards qualifying pace

17 min: Vergne is out there on a second run, but he locks up heavily into Les Combes. He wastes that effort and will have to go again.
