"Nico Rosberg continued preparation work with the FW31 today. Despite the wet conditions and a red flag temporarily halting proceedings this morning, Nico still managed to complete a race distance. We then spent the afternoon on general wet weather set-up work. We've had a good day and haven't come across any problems with the car."
