What happened: Heavy rain and electrical storms moved across the Autodromo Jose Carlos Pace during the São Paulo Grand Prix weekend. Weather conditions previously disrupted track activity, including support race delays. Lando Norris navigated the wet circuit to claim pole position ahead of George Russell.

Why it matters: Wet track conditions at Interlagos present critical tire strategy and visibility challenges for the grid. With Kimi Antonelli having clinched the 2026 World Championship in Mexico, the remaining rounds emphasize team positioning and runner-up standings. Unpredictable weather shifts historically create high variance across the São Paulo race distance.

What to watch: Teams will monitor radar forecasts heading into Sunday's Grand Prix at Autodromo Jose Carlos Pace. Track temperature and standing water will dictate tire selection at the race start.
