Formula 1 has rescheduled the Miami Grand Prix start time to 1 p.m. ET from the original 4 p.m. ET due to forecasts predicting heavy thunderstorms and rain. This decision, made in collaboration with the FIA and local promoters, aims to ensure the safety of drivers, fans, and teams while maximizing the opportunity to complete the race. The Miami Grand Prix is set for 57 laps, with a maximum active race time of two hours. The change comes ahead of a day when the weather is expected to be particularly challenging, with no clear indication of improvement. Florida's strict '30-minute rule' regarding thunder and lightning may lead to further delays, complicating the race's progression. Notably, this event will mark the first wet-weather race for Formula 1's new cars, which have faced criticism during prior wet conditions.
