Looks like rain may make some practice and Quali sessions interesting, but the jury is still out for raceday.
The unpredictable weather in Suzuka could play a crucial role in the outcome of the Japanese GP as showers are expected over the course of the race weekend.
With only 25 points separating the top five drivers in the Drivers' Championship, the title contenders know they can't afford to slip up should conditions be slippery at the Suzuka circuit.
According to the BBC's weather forecasts, sunny intervals are expected for the first practice session on Friday, but the heavens will open up later at night.
The wet trend will continue on Saturday and heavy showers are expected both during the day for qualifying and in the evening. Things will improve on race day and we should have clear skies for race day.
However, while the Beeb predict that the sun will be out on Sunday, other sites claim showers are possible during the day. We suppose that's why it's called unpredictable weather.
The weather has caused havoc in a couple of Japanese Grands Prix in recent years.
