A shower minutes before the scheduled 5 pm (0900 GMT) start sent fans and officials rushing for cover while standing water around turns 2 and 3 forced the FIA to put back the start after the medical car had assessed track conditions.

Once the standing water was cleared, the FIA said drivers would do two formation laps behind the safety car as teams quickly swapped out the slick tyres for intermediates.

"The spray is very bad," McLaren's Oscar Piastri said on the team radio as the drivers did two formation laps before a standing start for the final sprint race of the season.
