Rainfall remains a threat for the Miami Grand Prix as sudden showers arrived just a few hours ahead of the scheduled start time.
At around 12:45 local time (17:45 BST), rain hit the all-new Miami International Autodrome, forcing those in the paddock to run for cover.
However, after a few minutes, the intermittent showers passed and the sun broke through the clouds again, promptly drying the circuit.
What could happen in the race?
As it stands, the air temperature is sitting at just over 30 degrees Celcius in Miami, with that number expected to creep up as the afternoon wears on.
While hot and sunny conditions are forecast for the race, which begins at 15:30 local time (20:30 BST), further surprise showers cannot be ruled out.
That's due to the tropical and humid Florida climate, where extreme temperatures are tempered by heavy rainfall.
