After a very wet final practice session - topped by Mercedes' Lewis Hamilton - conditions worsened at the Circuit of The Americas, prompting race control to delay the start of qualifying by 30 minutes.
Several similar delays followed until at 1600 local time - three hours after the session had been due to start - and with no sign of a clear break in the weather, the decision was made to postpone.
It means qualifying will now start at 0900 on Sunday morning - weather permitting - with the race then due to begin at 1400.
The teams and drivers found various ways to entertain themselves - and the hardy fans in the grandstands - during Saturday’s delays.
We saw an impromptu pit-lane waltz from Red Bull’s Daniel Ricciardo and Daniil Kvyat, a makeshift canoe, breakdancing from a Force India mechanic, and a game of skittles using a ball and drinks cans from Toro Rosso’s Carlos Sainz and Max Verstappen.
The last time a qualifying session was run on a Sunday was at the 2013 Australian Grand Prix.
