The build-up to Sunday’s United States Grand Prix is forecast to be extremely wet, though conditions should improve in time for race day.
A tropical storm south-west of Mexico will send significant amounts of rain north to Texas over the coming days. Forecasts give different views of exactly much rain Austin will experience, but a high volume of rainfall is expected which will peak on Saturday. Conditions for Friday are little better.
By Sunday the forecast improves but a risk of rain showers will remain for the race. That is likely to affect how teams approach practice, and could mean we see very little running indeed. Friday running may be sacrificed to save wet and intermediate tyres for the race, and conditions on Saturday could lead to lengthy red flags.
F1 has not run in heavy rain at the Circuit of the Americas, which opened in 2012, but last year’s World Endurance Championship round at the track was hit by a rainstorm 90 minutes into the event:
