Lightning rules could pause the 2026 Miami F1 GP as Sunday rain looms
Forecasts show an 88% chance of rain and a 53% chance of thunderstorms on Sunday at the 2026 Miami F1 Grand Prix, and US law requires outdoor events to halt for lightning risk, potentially triggering a red-flag suspension with cars returning to the pit lane; for the US rounds (Miami, Austin, Las Vegas) teams may work on cars in garages during such stoppages, restart rules follow FIA Articles 57 and 58 with an 18-minute pre-restart notice, and weather pages note Friday/Saturday look dry while Sunday remains storm-prone.
