Good morning and welcome to our coverage of the final practice session ahead of the Belgian Grand Prix at a damp and dreary Spa-Francorchamps

Radars are showing that the rain is likely to stop during this session, the track will remain soaked though and the rivers that are sloshing around out there will definitely not clear up in the next forty minutes or so

It looks like it is just slightly brightening up and the rain is getting a little lighter, positive thinking.

Button on the team radio reckons that the circuit would be red flagged in this condition and is worse than the situation in Canada earlier in the season

Very little going on out there now as the rain continues to come down heavily, the spectators are getting under as much cover as they can find

The forecast for tomorrow is a lot better than today's which makes it even more frustrating for the teams that it is so damp today, they can't prepare their cars properly in such changeable conditions

Jenson Button the only man out there now, incredibly wet out there

Hamilton suffering from some serious twitches as he heads round, he has as much grip as he can possibly get with those tyres on and it is still too slippy to control, he's aquaplaning all over the place

Vettel straight back into the pits now, Hamilton has been out for a lap on the full wet tyres

An enormous amount of spray being kicked up by all the cars making visibility pretty poor, conditions are very bad indeed

A few more drivers are out on track now, Vettel is out there on the intermediate tyres, it really does look like a day for full wets though

Perez has the full wet tyres on and declares over the team radio that it is very wet, thanks for that Sergio

The local boy Jerome D'Ambrosio is out on intermediate tyres and is having to drive very cautiously indeed

It is very grey indeed at Spa and only D'Ambrosio and Perez have ventured out of the pit lane as yet
