Pre-season testing as resumed at the Circuit de Catalunya today following yesterday's weather-impacted botched schedule.
Teams found snow and sub-zero temperatures and when they arrived on site yesterday, with the track closed in the first three hours of the scheduled session as the medical helicopter remained grounded.
Eventually the track went green, but the cold and damp conditions only saw a handful of drivers venture out as caution prevailed, leading to almost a complete washout of Day 3.
Rising temperatures this morning in Barcelona should entice teams to resume their running, as everyone seeks to add mileage to the meager tally enjoyed so far this week. Relatively damp conditions are expected to remain in force however, at least in the early part of the day.
Most teams could split the day's workload between their drivers given the lack of track time enjoyed by a few, like Lewis Hamilton who should find himself behind the wheel at Mercedes today.
Tuesday's fastest man, Sebastian Vettel, is back behind the wheel today but the Scuderia may also run Kimi Raikkonen.
Max Verstappen should handle Red Bull's programme while Williams will once again split duties between Sergey Sirotkin and Lance Stroll.
Force India's Sergio Perez has yet to test the team's VJM11, so it's likely the Qilverstone-based outfit will entrust the Mexican with its day's programme.
Both Nico Hulkenberg and Carlos Sainz should both be seen out on the track today, while Sauber has already confirmed the presence of the Marcus Ericsson/ Charles Leclerc duo.
Stoffel Vandoorne and Kevin Magnussen could be on their own today, respectively for McLaren and Haas , while Toro Rosso's Brendon Hartley and Pierre Gasly are on call.
