Good morning from a slightly damp Monza. Final practice is just a few moments away, but it looks like they'll be starting on intermediate tyres to give themselves a safety net on the first few laps.
We've already had GP3 qualifying here with a few drivers struggling under braking in the conditions, but they have also helped a dry line appear around the circuit, so hopefully we'll see some slick tyre runs fairly early on in the hour.
Of course, this is the last chance for drivers to get their cars sorted ahead of qualifying this afternoon. Nico Rosberg currently has a 0.021s deficit to overturn from Friday if he is to beat team-mate Lewis Hamilton to pole.
@raiducii: That's true. We rarely have a wet Italian Grand Prix, but when we do it tends to shake things up a bit as a low-drag configuration is no longer that useful.
I was at Monza stood by the first and second Lesmos in 2008 and Vettel deserved that win. He was quick and pinpoint precise every lap. The only man who looked on a similar level was Robert Kubica in the BMW and he came through from 11th on the grid to 3rd.
We have Button heads out early.
It looks like he was on intermediates, but the TVs in the Monza media centre are placed in odd positions so it's hard to be accurate...
But I can confirm Alonso is on the inters in the second McLaren as he goes out on his installation lap.
Hello, I'm taking over from Laurence now the session is under way. Verstappen reporting the track is already quite dry and will soon be ready for slicks.
The FOM feed currently showing Ferrari chairman Sergio Marchionne smiling and laughing with Kimi Raikkonen (yes, he is laughing), Sebastian Vettel and Maurizio Arrivabene.
The Toro Rosso boys are the only ones with times next to their names. Verstappen is top with a 1:34.366, Sainz two seconds down but still on the intermediate tyres.
Sainz locks up those intermediate tyres and runs through the Turn 1 escape road.
That escape road is effectively four mini chicanes created by bollards. Going across there cost Rosberg the win last season if you remember.
@michael: Not if they spent all their remaining tokens ahead of the race.
@michael: It's looking a bit like that. Yesterday the top ten only had two non-Mercedes engines in it, in FP3 at least.
World champion Lewis Hamilton the only man on track but its an exploratory lap and he returns to the pits straight away.
@Piyush: Morning. Unfortunately, it's looking very unlikely.
Rosberg ventures out for a lap of his own. Lots of pressure on that man this weekend.
Rosberg reporting some "strange oscillations" from his Mercedes engine when it reaches eighth gear.
@Piyush: Haha, unfortunately not!
@michael: Well there's a lot we don't know about closed canopies, and certainly cleaning them is one issue that needs to be addressed. The main problem with closed cockpits at the moment is there has been nowhere near enough research done into them about the logistics of incorporating them into F1 car design.
No slick runs so far despite Verstappen's bold prediction it was time for dry tyres earlier. Still yet to run - the Ferraris, the Manors and Marcus Ericsson.
@achyut: Closed cockpit is the current talk around protecting the drivers' heads in the cockpit to prevent fatalities similar to Justin Wilson's in Indycar a few weeks ago - he was struck by flying debris from another car. Closed cockpits are a long way from being implemented but should certainly be considered if they make things safer for drivers.
Hamilton starts a timed lap on the intermediate tyre.
@Shirish: There won't be a wet race, but Mercedes is still pretty strong when it rains. All it would do would narrow the field up a bit and bring the non-Mercedes runners into play a little more. But as I said, rain is not forecasted for tomorrow.
@AhmedFaraz: They are looking ahead to next season, a lot of it was tactical to improve reliability for the 2016 power unit while also improving the current engine.
Sainz has bolted on some medium tyres as the clock ticks towards the half-hour mark.
Sainz lowers the benchmark to a 1:32.814.
Replays show Verstappen running deep into Turn 1 with a juddering right rear tyre as it searches for grip on the wet part of the track.
The track getting a little busier, with Nasr starting a timed lap on the medium compound.
Nasr moves into P3, 2.289s off the pace. Thrilling stuff so far this morning.
Hulkenberg returns to the pits after an exploratory lap on intermediates, which clearly aren't the correct tyre anymore.
