The first ABB FIA Formula E practice session for the inaugural Ad Diriyah E-Prix has been cancelled due to heavy rain.
FE's 2018/19 season-opening 45-minute session had been due to start at 7am local time, but after overnight rain hit the Riyadh area, the wet weather returned just before the action was about to get under way.
The FIA announced that the session start would be delayed, but as conditions did not improve, FP1 was cancelled 20 minutes after it should have started.
Track workers had attempted to sweep and pump the water away, but there was too much standing water around the 1.5-mile track for any running to take place.
An extended practice session has been rescheduled for 8.35am local time and is set to last one hour.
FP2 had been due to take place at 9.05am and was supposed to last 30 minutes.
The inaugural qualifying session for the Jaguar I-PACE eTrophy has also been cancelled, having been scheduled to take place at 7.55am.
That means the grid will be set by practice times, with Simon Evans to start on pole position alongside Bryan Sellers.
