Miami GP chaos looms as drivers warn of extreme weather

Core summary

With rain clouds gathering for Sunday’s Miami Grand Prix, drivers Carlos Sainz and Kimi Antonelli have voiced safety concerns. They argue that the flat circuit’s tendency to hold standing water could turn the race into a high‑risk sprint unless power limits are trimmed and tyre heating is boosted.

Why it matters:

The Miami layout is notoriously flat, so even a thin layer of water can create aquaplaning zones. Poor visibility and the proximity of walls amplify the danger, and a rain‑delayed start would force the FIA to invoke its “Rain Hazard” rule, reshuffling the weekend schedule and affecting fans worldwide.

The details:

• Power limit: Sainz urges cutting the 350 kW cap to 250‑300 kW for the race to curb wheel spin on slick surfaces.
• Aquaplaning risk: Standing water on the track could cause cars to lose traction and slide off the racing line.
• Visibility: Close barriers and spray reduce sightlines, especially in heavy rain.
• Lightning: Drivers are uneasy about sudden thunderstorms and the associated safety protocols.
• Tyre heating: Antonelli suggests raising tyre‑blanket temperatures to keep wet‑weather tyres in the optimal range.
• Current regulation: Wet‑weather power is already limited to 250 kW with no boost, but drivers say more tweaks are needed.
• Intermediate tyres: No driver has used them this season, leaving grip levels uncertain.

What's next:

The race director can declare a “Rain Hazard” up to two hours before the start if the rain probability stays above 40 %. Teams will keep a close eye on the forecast, and any delay could push the start time or force a shortened race. Drivers hope the FIA’s safety measures will allow the spectacle to go ahead without compromising control.
