Qualifying at the Brazilian Grand Prix was postponed on Saturday evening due to heavy rain at the Interlagos circuit in Sao Paulo.
Qualifying is now scheduled to take place at 7:30am local time (10:30am GMT), though heavy rain is also expected on Sunday too.
The race is now set to start at 3:30pm (GMT) – 12:30pm local time.
It remains to be seen how the grid for Sunday’s race would be decided if qualifying was unable to take place.
The session, which sets the grid for Sunday’s grand prix, was constantly pushed back on Saturday afternoon, with the FIA conducting regular checks of the track surface.
However, at 5pm local time, FIA race director Niels Wittich made the decision to postpone the session.
Lando Norris, in dry conditions, had earlier in Brazil to cut the deficit to Max Verstappen in the world championship to 44 points.
Verstappen received a post-race penalty for a virtual safety car infringement, dropping him from third to fourth.
The three-time F1 world champion also has to for Sunday’s grand prix after taking a new engine.
