The Miami Grand Prix, set to take place at 4 p.m. local time on Sunday, faces uncertainty due to forecasts predicting heavy thunderstorms. According to U.S. law, any outdoor event must be halted if lightning is detected within an eight-mile radius, which has previously affected IndyCar and NASCAR races. The FIA (Fédération Internationale de l'Automobile) is expected to provide an update on the race schedule on Saturday afternoon, allowing officials to evaluate the weather conditions. There are three support events scheduled for Sunday, including a Porsche Supercup race, an F1 Academy race, and a Formula 2 race. Sources indicate that the Porsche Supercup race may be canceled, and adjustments could be made to the F1 Academy and F2 races to allow for an earlier start for the main event. If the race is delayed due to lightning, a 30-minute wait without lightning is required before it can be restarted. As sunset in Miami is at 7:52 p.m., visibility concerns will also play a crucial role in the decision-making process. A wet race would also introduce unique challenges under F1's new regulations, including restrictions on battery boost modes and power deployment. Drivers have voiced concerns about the increased risks associated with racing in wet conditions, particularly regarding visibility and closing speeds between cars.
