Free Practice this morning started out nice and dry so we saw plenty of running before a shower kicked in with about 15 minutes to go. The only real notable incident was Vettel coming to a halt in the exceedingly narrow entrance to the pitlane - the problem as yet undefined.

Weather update

When it was dry, it was very, very dry. When it rained, it really poured. The sight of the mechanics dashing back into the garages after pushing their cars to a standstill was quite immense. A sea of umbrellas went up in the crowd, and many drivers got out of their cars. For qualifying, they can't do that, and more rain is expected.

One to watch

We'll assume that Red Bull have managed to fix whatever was wrong with Vettel's car, but keep your eye on him anyway. He hasn't looked on top form so far this weekend, and he's usually so dominant in qualifying that this could be someone else's chance to get pole position. It could be Hamilton in the McLaren, or it could even be Kubica in his bright yellow Renault.

Predictions please

Will the rain cause no end of havoc? Who will be the first to end up in the barriers? Who will be the surprise knockout of the first session? Will Vettel get through an entire session? And of course, who will be on pole position? Hey, let's have a poll:
