Wet weather is already causing chaos ahead of the Miami Grand Prix, with the first support race of the day having been cancelled.
It was announced that the McLaren Trophy America race due to start at 08:00 local time was cancelled due to inclement weather.
F1 has moved the Miami GP forward by three hours to start at 13:00 local time, but significant rainfall and thunder has already arrived.
The cancellation of the first support race has thrown Formula 2’s feature race into doubt, on what is the junior championship’s first trip to North America.
