A busy track in the final minutes with everyone out on track except the Red Bulls and Ferraris.
Schumacher moves up to sixth on his new tyres but has it deleted for exceeding track limits.
Perez improves to sixth overall, 0.4s off Verstappen.
In the drop-zone: Schumacher, Albon, Vettel, Magnussen and Latifi.
The order after the first runs: Verstappen, Leclerc, Bottas, Hamilton, Sainz, Russell, Ocon, Alonso, Norris and Perez.
Bottas goes third fastest in the Alfa Romeo. Strong lap from the Finn.
Verstappen goes quickest with a 1m19.222s, 0.283s ahead of Leclerc. Hamilton slots into third; Russell fifth.
Leclerc smashes Perez's benchmark by 0.9s to take top spot.
Perez goes fastest with a 1m20.408s, 0.168s ahead of Tsunoda. Albon, Gasly and Schumacher complete the top five.
Albon sets a 1m20.859s to take top spot off Schumacher. A tenth clear of the Haas duo.
Schumacher sets the first representative time of the day with a 1m21.024s, less than a tenth ahead of Magnussen.
It seems that teams are going for two warm-up laps to get their tyres into the right window.
Q1 is now underway - Schumacher and Magnussen are the first two drivers out on track.
It doesn't look like but there's a 60 percent chance of rain.
We're just moments away from the start of qualifying.
#F1#BBCF1#MexicoGP QUALIFYING: 15 mins to Q1, with air temp 25C & the track 48.8C. Currently dry. The first shower of the afternoon has formed ~35km due east over mountains, but none are presently in the immediate vicinity. FIA official risk of rain is 60% for this session.

Mercedes are working on Hamilton's brakes. Another brake-related issue? Was a similar story ahead of the US Grand Prix.
Mercedes locked out the front row last year with Bottas on pole ahead of Hamilton and Verstappen.
Who will claim pole? Verstappen, Russell or Hamilton?
Chequered flag out in FP3 - Russell, Hamilton, Verstappen, Leclerc and Perez is the order.
Juicy.
Alonso manages only 13th for Alpine.
