The Miami Grand Prix has been moved forward by three hours to 18:00 BST (13:00 local time) because of the threat of thunderstorms.
And world champion Lando Norris says the Formula 1 drivers will be “thrown in at the deep end” by the expected wet weather on Sunday.
The McLaren driver is one of the vast majority of the grid who have not yet experienced the 2026 cars in wet conditions, following the biggest rule change in the sport’s history.
The massive amount of electrical power available in the new engines, and the issues teams have been having deploying it in a predictable manner, threaten “a bit more chaos,” as Norris puts it.
“I don’t know how wet it’s going to be,” said Norris, who qualified fourth behind Mercedes’ Kimi Antonelli, Red Bull’s Max Verstappen and Ferrari’s Charles Leclerc. “It’s going to be a big challenge on race day for everyone to perform, find the limit.
“Obviously, you can’t afford to make any mistakes. We’re thrown in the deep end, but that’s what we’re here to do. I look forward to it.”
