Thunderstorms expected on Sunday in Miami, what does that mean?

The rain forecasted for Sunday raises various challenges for Formula 1 and the governing FIA with the new cars, with the laws in Miami also a factor as they require people to seek shelter should there be lightning.

In that regard, the FIA played down speculation regarding the cancellation of the race on Sunday, claiming the Hard Rock Stadium and the garages could be used as shelter, which means the race will simply be red-flagged.

In a statement, the governing body said: “We are closely monitoring the weather forecast for this weekend. Having faced a similar situation last year in Miami with threats of thunderstorms, we have a contingency plan in place and will activate it if needed to minimise disruption to the on-track programme.”

In terms of the racing, the FIA has addressed wet weather concerns from the drivers with the new cars.

The 2026 F1 machinery have less downforce, narrower tyres, and less mechanical grip, with the instantaneous torque from the electric motor making driving in wet conditions quite tricky.

In the regulations changes issued over the F1 April break, the power of the electric component has been capped, while a recent draft of the rules showed that boost mode will not be allowed.

Active aero will be limited to the front wing only in wet conditions, a decision the FIA claimed they have taken based on simulations regarding energy usage and the requirement for drag reduction.

Furthermore, the temperature of the tyre blankets will be increased to make sure the wet Pirelli compounds function properly and are up to temperature in a short time, although that change is only related to Intermediate tyres and not the full Wet.

However, one issue remains, and that is related to the nature of the parking lot nature of the track in Miami, which means water drainage may be an issue.
