This rain is actually very heavy now.
And the Mercedes cars are on intermediates.
This could get very tasty.
Q3 begins in increasingly heavy rain.

Bottas is looking good here today. He seems to be getting it done.
Hamilton is a little less consistent but when he manages to put a lap together, it is lightening quick.
P5 for the Canadian rookie in that session.
He's performing superbly today.
IN: Hamilton, Bottas, Verstappen, Vettel, Stroll, Raikkonen, Ricciard, Massa, Vandoorne, Ocon
10 Ocon 1:37.580, 11 Perez 1:37.582
Two thousandths of a second gets Ocon into the top 10.
OUT: Perez, Hulkenberg, Alonso, Kvyat, Sainz
And Vandoorne duly improves to seventh place! That sends Sergio Perez out in the Force India.
Nico Hulkenberg's Renault also bows out after what the German describes as a "pretty terrible" effort.
Alonso is also eliminated, as are the Toro Rossos.
Massa makes an improvement to go eighth. That dumps Vandoorne out.
But Vandoorne still has a lap to complete. Here he comes...
Q2 ends.
Ocon ptuts his Force India into P6.
Alonso has done a lap now - he was always planning to be Vandoorne's wing man in this session with the engine penalties he is due to take. Can he slipstream his team-mate into Q3?

As soon as they are trying to get onto the power, they are struggling to get traction out of these low speed corners and chicanes.
Huge oversteer from some of them.
Vandoorne improves to seventh.
Ocon in trouble now.
Hamilton sets a new best time of 1:35.344 on a new set of inters.
That's eight tenths up on Vettel.
Three minutes to go.
In trouble are Vandoorne, Kvyat, Sainz, Perez. Still nothing from Alonso.
"I suggest a hard outlap to get these tyres going. Vettel's lap on these was quick," says the Red Bull team to Daniel Ricciardo...
"Raining a lot more into turns six and seven," says Daniil Kvyat.
That's the Lesmos. Not somewhere you want rain...
Less than five minutes to go.
Vandoorne in 11th is just two tenths shy of 10th-placed Esteban Ocon.
All to play for in the battle to get into Q3.
