FIA Issues Uncommon Weather Alert Ahead of Brazilian GP

The FIA issues a rare level 4 rain warning for Saturday at the Brazilian Grand Prix in São Paulo, threatening heavy disruption across Sprint day sessions.

Friday offers a largely dry window, allowing teams to bank meaningful laps in free practice and refine baseline set-ups ahead of the weekend’s Sprint qualifying.

Forecasts point to severe conditions on Saturday, with heavy rain expected early and potentially lasting to 09:00 local time, creating treacherous grip levels and persistent spray.

The governing body assigns an 80% chance that wet conditions affect the circuit before the Sprint, with rainfall likely to register at levels three to four on its severity scale.

Sprint qualifying appears most exposed. As in last year’s Saturday deluge, delays, red flags, or schedule adjustments remain plausible if drainage is overwhelmed and visibility drops.

The Sprint is set two hours after the heaviest rain is expected to ease, yet São Paulo’s microclimate can prolong showers and keep the surface inconsistent through the afternoon.

Winds compound the challenge. Gusts up to 75 km/h are forecast in Sprint qualifying, easing to 65 km/h by regular qualifying, increasing crosswind risk into Turn 1 and middle sector.

Drivers will chase stability through lift-and-coast, brake migration tweaks, and gentler throttle maps, while engineers balance wing level, ride height, and wet-dry compromises across a restrictive Sprint weekend.

With limited set-up freedom once parc ferme applies, early calls on tyre allocation and aero load become decisive if the crossover to slicks opens briefly during drying phases.

The competitive picture could reset. McLaren leads, with Lando Norris and Oscar Piastri split by one point. Max Verstappen pursues, while Ferrari and Mercedes round out the top five.

Strategy windows may hinge on intermediates versus full wets, Safety Car likelihood, and pit entry exposure, with track evolution slower than usual if persistent showers limit rubbering.

Expect an attritional Sprint if rainfall persists, with execution, visibility management, and opportunistic tyre choices likely to dictate outcomes more than headline pace.
