Overview
- Brazil’s meteorological service placed São Paulo under an orange alert for Saturday, forecasting 30–60 mm of rain per hour and strong gusts that could disrupt Interlagos sessions.
- The FIA issued a high-level rain warning, reported as level 4, citing severely reduced visibility from spray with current ground‑effect cars and the possibility of suspending track activity.
- Brazilian Civil Defense pushed mobile alerts advising caution, with officials flagging a peak storm window around 06:00–09:00 local that clashes with the Sprint timetable.
- Rescheduling options are constrained by regulations requiring at least three hours between the Sprint and qualifying, making delays or a Sunday shift contingent on safety assessments.
- There is recent precedent from 2024 for postponements in heavy rain, and the stakes are heightened with Lando Norris on Sprint pole and narrowly leading the drivers’ standings over Oscar Piastri.
