• REPORT: Snow Day in Spain

Snow, snow and even more snow brought the on-track action to a standstill on day three of 2018 pre-season testing, but that wasn't enough to stop the fun.

F1 drivers experienced the unusual scenario of lapping the Circuit de Barcelona-Catalunya in light snowfall on Tuesday afternoon, although the wintery spell didn't last for long.

However, overnight and through Wednesday morning, heavier bursts of snow bathed the Spanish track in white and a whole day of testing was effectively wiped out.

Teams were snowed in and the Mercedes-AMG F1 W09 EQ Power+ was confined to the garage for the entirety of the day.

The start of the session was delayed by three hours and when the light did turn green, there wasn't much track activity at all, with teams seeing little reason to head out on track and complete laps.

A few drivers ventured out to do installation runs and McLaren's Fernando Alonso put in the only timed lap of the whole day, with a best of 2:18.545 on (unsurprisingly) the Wet tyre.

In total, just 17 laps were completed over the course of the day. But, on the plus side, it allowed teams and drivers the chance to enjoy the snow.

Even though the car didn't emerge from the garage at all on Wednesday, Mercedes still had plenty of work to do, reconsidering its programme and preparing the car for Thursday's running.

"We now have one-eighth less testing available to us," explained the team's Technical Director, James Allison. "So we shuffle our programme around and try to fit all the work we need to do into seven days instead of eight.

"Winter testing is always tight, but this is only because you're trying to achieve as much as possible in the time available. There's just slightly less time available now. It is the same challenge for all the teams, so we take it on the chin and move on.

"Even during normal winter testing the track is never very representative of what happens later in the year. So it's not unusual to be trying to make the best of the available conditions and to extrapolate from them what you might expect to see in the summer.

"This week's weather just makes the challenge more extreme, as the cold makes it harder to get the car in its right operating window. But, once again, this is the same for everybody."

However, with extra time on their hands, Mercedes had the chance to add a new team member to its crew: Karl Snowman. He had a great day and was the centre of attention, completing photo shoots, media calls and hanging out with the drivers.

"Hands down this was the best day of my life," Karl said. "It's been over ten years since I was last invited out to F1 testing - back at Silverstone in 2005 with Renault.

"It's not my first time in Barcelona, I was here in 2002 with McLaren when Mika started a snowball fight in the pit lane. But today has been the most fun yet.

"The team were really nice to me; everyone was so cool and chilled out. They gave me a warm welcome, but not too warm - just the way I like it.

"I don't quite understand why everyone made such a fuss about the weather. I mean what do people expect? There's a reason why it's called winter testing.

"I would also like to address the rumours about my wellbeing. Reports about my demise have been greatly exaggerated. I can assure everyone that the team is treating me extremely well and found appropriate accommodation in a cold storage unit for me."
