Matt Scott:, external No FP2 and no Q3, and a dry(ing) track for the race. I'm not saying it'll be great racing, but it'll certainly be interesting!

Andrew Priestley:, external With track conditions likely to be very changeable during the race, surely this plays into the hands of the adaptable Hamilton.

Ross Parker:, external Hamilton has the potential to win many more titles, but only if he's in a competitive car. Just look at what's happened to Alonso ., external

After retiring from the Russian Grand Prix with a throttle problem, Nico Rosberg will want everything running smoothly today. As a result, he is being extra certain everything is ticking over as it should before the race starts.

"There's something wrong with the front tyres , juddering," he says over team radio.

"Sounds like they just cold," he is told in response.

Top work by Toro Rosso as they've managed to get Carlos Sainz's car fixed up and ready to go after his crash in qualifying. The Spaniard can start the race.

“There's been some bad news for Valtteri Bottas. The Williams driver was due to line up 10th after the Ferrari drivers’ penalties but the team discovered that part of his rear suspension had broken. It is so integral to the gearbox that the ‘box needs changing to replace it, and that means a five-place grid penalty. In the circumstances, the Finn did well to qualify only  0.335secs slower than team-mate Felipe Massa.”

Mercedes are struggling to contain their excitement. They write on Twitter:, external "A Silver Arrows front row lockout, tricky track conditions, mega fans in the stands, millions more around the world, and, of course, the F1 World Championship potentially within reach... this could be one heck of a day!

"Settle in everyone! The greatest show on earth is about to begin."

The pitlane is open and out rumble the cars on to the track, a bit of spray kicking up as they venture off for an exploratory lap but it is clearly drying up very quickly.

James Macdonald:, external HAM is certainly good enough, but if drivers of the calibre of ALO, RIC, BOT, VET get competitive machinery, 6 would be tough.

Dan Culyer:, external Hamilton can go on to win six titles. He'll now have first pick on cars, so has more years left at No. 1.

FK:, external Lewis will win many more titles, as long as Mercedes stay top and Nico is his team mate. Not sure if he had a Riccardo, Vettel or Alonso.

Shield your eyes! Something those in Austin haven't seen for a while has just appeared in the sky...the sun.

“The Mercedes drivers might have locked out the front row but if it stays wet they may well not have things all their own way in the race. Daniel Ricciardo was impressive throughout a difficult qualifying session and he and Red Bull team-mate Daniil Kvyat are on the second row, Ricciardo just over a second off the Mercedes.

“‘In these conditions,’ Ricciardo said, ‘there is always a fine line but you are better off being on the more side of risks and taking risks. If you don't drive in these conditions with confidence, you don't get far. As soon as a bit more aquaplaning or rain scares you, then everyone will drop in front.’

“The Australian sounds like he will be in full ‘honey badger’ mode in the race. ‘For us as a team and me as a driver, we are not fighting for a championship at the moment, and these are conditions that suit us,’ he said. ‘It is an opportunity in the race. To put it all on the line makes sense.’”

Red Bull's Daniel Ricciardo, who lines up third, is in a confident mood. 

He says: "We have a genuine chance today of taking our first win. 

"The track looks a lot drier that it did this morning and if it stays like this we will definitely start on time."

An observant tweet from Ferrari. They are indeed people. Wet people by the looks of it.

It is wet, possibly a tad windy, but that is not spoiling the enthusiasm of the Dallas Cowboys cheerleaders. Some very energetic dancing going on at the moment to entertain the crowd.
