Valtteri Bottas topped the timesheets during practice ahead of the 2019 Japanese Grand Prix on Sunday, putting Mercedes in the driving seat with a fastest lap of one minute, 27.785 seconds.
Bottas led team-mate Lewis Hamilton to a Mercedes one-two in each of Friday's two practice sessions. Ferrari duo Sebastian Vettel and Charles Leclerc ended first practice in third and fourth, respectively, while Red Bull's Max Verstappen improved in the second session to round out the top three.
Formula One posted a breakdown of the classification from P2:
Officials announced all Formula One activities scheduled for Saturday had been suspended due to Typhoon Hagibis, per BBC Sport's Andrew Benson. As a result, qualifying will take place before the race on Sunday morning at 2 a.m. BST.
Every driver in the field participated in the session and recorded at least 20 laps in a bid to get a fast time on the board as early as possible in anticipation of any further disruptions.
The threat of further session cancellations created a sense of urgency among drivers during practice, though a rain-free second practice granted some relief from the weather warnings.
Standings leader Hamilton has won at Suzuka Circuit in each of the past two Japanese Grands Prix—the Briton has won four of the past five races at this venue—and returns eyeing his third in a row.
The likes of Bottas and Verstappen each shared hairy moments during a second practice session featuring several yellow-flag warnings:
Ferrari star Leclerc has clinched pole in the past four races this season, and the Monaco native finished strongly to pip team-mate Vettel to fourth place at the end of Friday's activity.
Mercedes will likely be content with the current starting order in the event Sunday's qualifying is cancelled prior to the Grand Prix, with their two stars spearheading in first and second.
Verstappen's Red Bull team-mate, Alexander Albon, finished sixth in both Friday's sessions and will hope for improvements come Sunday, as will Vettel following his fall to fifth.
Renault will also be out to do a lot better following car troubles during P1 and P2, with drivers Daniel Ricciardo and Kevin Magnussen settling for 17th and 16th place, respectively.
