US law might affect the Miami GP as the FIA looks into weather issues.

A U.S. law might affect the Miami Grand Prix because of worries about the weather forecast for the race day. There’s a chance of thunderstorms around Miami on Sunday. Earlier in the week, The Weather Channel said thunderstorms were likely. Now, they expect rain showers in the morning and thunderstorms in the afternoon, with an 80% chance of rain.
Accuweather also predicts some showers and a strong thunderstorm that could impact the race. The FIA’s official forecast shows about a 40% chance of rain. A spokesperson told RacingNews365 on Thursday, “We are watching the weather closely for the weekend. Last year, we had similar thunderstorm threats in Miami, and we have a backup plan to reduce any delays if needed.”
Last year, bad weather caused the F1 Academy race on Sunday to be canceled. There were concerns the main F1 Grand Prix could be affected, but thankfully, the rain stayed away and the race went on in dry conditions.
If the weather gets really bad, FIA rules say the medical helicopter has to be able to fly safely. If it can’t, the race will be stopped. Article 57 of FIA’s rules might also come into play for poor weather.
Importantly, there’s a U.S. law that requires any public event to stop right away if a thunderstorm or lightning is very close. Most outdoor sports and events must wait at least 30 minutes after lightning leaves the area before starting again.
Safety is a big concern for the fans at Hard Rock Stadium, where 275,000 people came last year. Workers on site have rules from OSHA to stop the event if lightning is near.
If the FIA sticks to the original 4pm start time, a federal law means the race would have to pause during storms and only continue when it’s safe. The race must finish within four hours before sunset, and organizers are talking with teams and drivers about the best plan.
The FIA could move the race to an earlier time on Sunday, like they did at the 2024 Brazilian Grand Prix when thunderstorms were a big threat. They could also move it to Saturday—when the weather looks dry and warm—but since Miami is a sprint weekend, that would mean rescheduling other races.
Finally, the FIA Race Director can call a ‘Rain Hazard’ two hours before the race if there’s about a 40% chance of rain, warning everyone to expect slippery track conditions.
