Yeeha! Romain was P12 in that session, by the way.

So, assuming nobody is feeling like a maverick and wants to burst out of the pits in the next two minutes, this is how FP3 looks.

1. Lewis Hamilton

2. Sebastian Vettel

3. Nico Hulkenberg

4. Valtteri Bottas

5. Carlos Sainz

Lewis Hamilton is in the garage, looking extremely relaxed. Sebastian Vettel is sat down doing a bit of paperwork, Fernando Alonso is chatting with engineers.

Sergio Perez is sat in his car in the garage, staring at a picture of the Pope. (Honestly, that's what he's doing).

We have six minutes remaining - but it's fair to say FP3 is over.

Wrestling references are welcomed, nay, encouraged.

The few drivers out on the track are testing out strategies, rather than pushing for times. Daniil Kvyat has just pitted, while Marcus Ericsson and Max Verstappen are ploughing through the puddles. There are still no spectators in the Circuit of the Americas.

It's worth noting just how good that fastest lap from Lewis Hamilton was. He is almost a second quicker than anybody else. If this does become the weekend he wraps up the title - he will have done it by re-enforcing his reputation as a maestro in the wet conditions.

Contrasting approaches on show. Nico Rosberg goes out, but Mercedes decide it is too treacherous and call him straight back.

Force India ask Nico Hulkenberg is he can manage one more lap - "It should be fine," he says.

Now then boys. Conditions are worsening, but you have 20 minutes left of what could turn out to be qualifying - what have you got left in the tank?

Red Bull have improved slightly - Daniil Kyvat is up to sixth and Daniel Ricciardo is eighth. The Australian is currently on the track.

Shaky moments for Sebastian Vettel, who survives one little wobble through the wet, but can't survive a second miscalculation and spins. He then, curiously, reverses down the track a few yards, a bit like he's doing a manoeuvre on his practical test.

"The conditions are quite bad," he tells his Ferrari team.

The German is still second, mind.

Lewis Hamilton, on the weekend he could seal a third world title, is the first man to break two minutes, recording a 1:59.517.

We have 28 minutes of FP3 remaining.

Susie Wolff, the Williams test driver, is looking happy as Larry in the rain.

It's Nico Hulkenberg and Valtteri Bottas who are looking the danger men. Hulkenberg is up to second - just 0.116secs behind Sebastian Vettel. Bottas is marginally further back in third.

If this does turn out to be qualifying, they will be on the front of the grid, with Vettel set to receive a 10-place grid penalty.

Meanwhile, Lewis Hamilton is back out...

A reminder that the grandstands are empty in Austin on safety grounds. We have racing, but no fans.

Sound the Bernie Ecclestone klaxon. F1's big cheese has walked through the doors at the Circuit of Americas underneath an umbrella that is four times bigger than him.
