FIA declares 'Rain Hazard' for the Canadian Grand Prix

Ahead of the Canadian Grand Prix, the FIA's official weather system indicates a more than 40% chance of rain for Sunday. As a result, Race Director Marques has now declared a 'Rain Hazard'.

According to Article B1.5.11, it is mandatory this year for race control to declare a so-called 'Rain Hazard' as soon as the probability exceeds forty percent that it will rain during the race. This must be done at least two hours before the start of qualifying. The warning remains in effect from the moment it is announced until the signal is given for the end of the race session.

The 'Rain Hazard' therefore says nothing about how much rain is expected or what impact this might have on the race. It is a way for race control to let the teams know that they should be prepared for rain. If this warning is issued less than two hours before qualifying, the teams are permitted to make certain adjustments to the car, even if it is already in Parc Ferme.

In previous years, there was no similar provision in the regulations. In 2025, there was only a provision relating to heat, under which a so-called 'Heat Hazard' could be declared. This comes into effect as soon as the temperature rises above 31 degrees Celsius. In such cases, the cooling system must be connected to the drivers to prevent them from overheating during the race.
