F1 | Severe weather alert in Brazil puts São Paulo Grand Prix at risk. The FIA has issued a rare level 4 weather alert for the Brazilian GP.

Orange alert for the São Paulo region

Local authorities, confirmed by the FIA, have issued an orange alert for São Paulo due to a possible extratropical cyclone. Forecasts predict extremely heavy rainfall, reaching up to 60 mm/h, with winds potentially exceeding 60 km/h.

The Sprint, scheduled for 11:00 local time (15:00 GMT), currently has a “high probability” of rain, rated between levels 3 and 4 on a 4-point scale. Conditions could mirror last year’s event, when Qualifying was canceled and postponed to Sunday morning due to a severe downpour at Interlagos.

A concerning recent precedent

In 2024, the São Paulo Grand Prix was already heavily impacted by torrential rain, which forced the suspension of on-track activities. According to the Brazilian meteorological service, this year could be even more critical, with an intense thunderstorm front expected on Saturday.

The FIA is closely monitoring the situation, in constant contact with race control and local authorities. If rainfall and wind exceed safety limits, schedule changes or session suspensions cannot be ruled out.

Friday practice and Sprint qualifying currently safe

So far, Friday activities – including free practice and Sprint qualifying – are not threatened, as the storm front is expected only from Friday night into Saturday. The main risk concerns the Sprint Race and morning support sessions, which could face heavy rain and strong gusts of wind.

Race control has already prepared contingency plans for delays or interruptions. In extreme rain, cars may be forced to start behind the Safety Car, or the session could be postponed in the worst-case scenario.

Formula 1 faces Interlagos’ unpredictable weather

The Interlagos circuit, located over 700 meters above sea level, is notorious for unpredictable weather that can change drastically in minutes, making forecasts unreliable. Tropical storms in the region at this time of year make the track extremely slippery and challenging, increasing the risk of aquaplaning and incidents.

If the level 4 alert is confirmed, the Brazilian GP weekend could become one of the most demanding of the season, both in terms of driving and strategic decisions.

Eyes on Saturday: potential chaos ahead

With a level 4 weather alert and forecasts of torrential rain and strong winds, Saturday at the Brazilian GP could be a challenge not only for the drivers but also for the organizers. The hope is that conditions improve enough to allow the Sprint to proceed, but the risk of another postponement remains real.

While awaiting official FIA updates, teams are preparing for a potentially chaotic Saturday, where weather strategy could prove just as decisive as on-track performance.
