That's just how close the times are now, Verstappen has two tenths on the rest but everyone else is tightly packed behind.

The two Ferraris have exactly the same times, that surely can't be coincidence...

E: "We're getting reports of rain at Turn 12."

LH: "There's nothing there last time."

Those clouds are getting darker. And it's starting to rain...

Everyone is out on the supersofts. Verstappen is top of the board with a 1:08.205

Now the drivers’ championship has been decided, the sting has gone out of this season, constructors’ championship notwithstanding, and you can feel it in the paddock.

The atmosphere is a little flat this weekend. The team bosses are rushing about from meeting to meeting, something that’s more visible here than normal because it’s harder for them have meetings in private because of the nature of the buildings, but little concrete progress is being made on talks about the future of F1.

The drivers’ market is also a little flat, with only seats at Williams and Toro Rosso still undecided - even if Force India for some bizarre reason are still refusing to confirm publicly that Lance Stroll will join Sergio Perez next season.

There's some varying forecasts out there. But let's see what happens.

Jack Nicholls, Jolyon Palmer, and Jennie Gow are live on the internet-only airwaves, and they can be heard at the top of the page.

Q1 will be underway in a few minutes time.

We should all know by now who the good drivers are in wet conditions. Max Verstappen is one of them, especially with this manoeuvre from 2016.

"If he'd have turned up on Thursday and done his track walk, he'd have known all about that."

So Bob, as for tomorrow's weather BBC Weather says "light cloud and a gentle breeze", but as Andrew Benson says, only a fool second guesses the weather in Sao Paulo.

The weather forecast earlier was for a 60% chance of rain during qualifying, but it doesn’t look like it right now.

The sky is mainly blue and what clouds there are are white.

But it’s a fool who second-guesses the weather in Sao Paulo. Ahead of qualifying, the big question is whether - as it looked in final practice - this session will add another twist of exquisite torture to Ferrari, in the sense that a pole for Sebastian Vettel would make them even more painfully aware than they already are of how much they have let slip through their fingers this season by their own errors.

Here's Andrew Benson and Ian Fergusson with the weather...

Jenson Button's first and last Formula 1 World Championship.

Team Brawn had a storming year as a new team, with a new car and new developments, but virtually no money following the departure of Honda just before the start of the season.

It was a fairytale story for a privateer team with no money. Button finished fifth after a few handy overtakes to win the title in Brazil from the hard-charging Red Bulls who had been catching up fast in the preceding races.

Phew...
