FIA Declares Rain Hazard for Canadian Grand Prix

FIA race control has officially declared a Rain Hazard for Sunday's Canadian Grand Prix, following a weather forecast that shows more than a 40% chance of rain on race day. Race Director Rui Marques triggered the protocol as required under the sport's updated regulations for 2025.

Why it matters:

This early warning system, mandated by Article B1.5.11, ensures teams have adequate notice to prepare for potential wet conditions. The Rain Hazard must be announced at least two hours before qualifying and remains active until the race ends. Critically, if the warning comes inside that two-hour window, teams are allowed to make certain car adjustments even if the vehicle is already in parc ferme — a significant operational allowance that could affect qualifying and race strategy.

The details:

• Weather Forecast: The FIA's official system indicates a greater than 40% probability of rain during the Grand Prix, triggering the mandatory hazard declaration.
• New Regulation: The Rain Hazard protocol was introduced this season to standardize communication and give teams more time to adapt to changing weather prospects.
• No Specifics: The warning does not quantify the expected rainfall or its intensity — it is purely a readiness alert.
• Parc Ferme Exception: A key provision: if the warning is issued less than two hours before qualifying, teams may modify their cars beyond normal parc ferme restrictions, subject to specific technical guidelines.

What's next:

Teams will now closely monitor updated forecasts and may adjust their setup decisions earlier in the weekend. The Canadian Grand Prix at Circuit Gilles Villeneuve is notorious for sudden weather shifts, so the Rain Hazard adds another layer of strategic complexity. Drivers and engineers will prepare for both dry and wet scenarios, with the potential for an unpredictable and exciting race come Sunday.
