MONTREAL: Aston Martin's double world champion Fernando Alonso set the fastest lap in a wet and wild practice at the Canada Grand Prix on Friday with both sessions run under a severe weather watch at the Circuit Gilles Villeneuve.
Alonso, 15th in the rain-hit first practice, took advantage of early dry conditions in the second with the Spaniard clocking a time of one minute and 15.810 seconds around the island circuit, almost a half second ahead of Mercedes' George Russell.
"It was difficult to take many learnings into the rest of the weekend as each lap the conditions were changing," said Russell. "First it was spitting, then it was drying, then it was raining again.
"The car was feeling good overall, but we will only learn about our position relative to others tomorrow (today)."
Canadian Lance Stroll, who grew up in Montreal and whose father owns the team, brightened up a dreary day for the home crowd posting the third best effort ahead of Ferrari's Charles Leclerc, the winner two weeks ago in Monaco.
It was a promising start to the weekend for Ferrari with Leclerc third best in the morning session behind team mate Carlos Sainz, who was 13th best later in the afternoon.
Two teams that do not routinely feature at the top of the time sheets made surprise appearances with RB's Daniel Ricciardo fifth ahead of Haas's Kevin Magnussen.
Seven-times world champion Lewis Hamilton was seventh fastest for Mercedes.
McLaren's Lando Norris, who topped the first session, finished at the very bottom of the second.
The conditions made it difficult to gauge which teams have arrived in Canada ready to challenge for the podium in a season that has become increasingly competitive.
There have been three different winners in the last three races, Norris in Miami, Red Bull's triple world champion Max Verstappen in Imola and Leclerc in Monaco, and there could be more surprises with the forecast calling for rain for today's qualifying and tomorrow's main event.
"I think it's impossible to tell who's where today," McLaren CEO Zak Brown told Sky Sports. "Maybe we'll find out tomorrow.
"There's no reason why we shouldn't be very competitive, as we have been pretty much all season.
"The last three races have been super strong so I see no reason why we can't be here.
"With these changing weather conditions, if this is what tomrrow (today) and Sunday (tomorrow) is like, then it's going to be about being in the right place at the right time."
Verstappen, who was dominant in Montreal a year ago leading every lap from the pole, did not get his bid for a Canada hat-trick of wins off to a smooth start.
After clocking the fifth best effort in the first session the Dutchman could manage only four laps in the second before pulling into the pits saying on the radio that he smelled smoke coming from the car.
Both sessions were run under changeable threatening conditions.
About an hour before first practice a ferocious storm rumbled across Ile-Notre Dame drenching the island circuit and pelting spectators with hailstones as they were evacuated from the stands, delaying the start of the session by 20 minutes.
The afternoon practice got underway in dry conditions but with ominous dark clouds, and drivers lined up early to get on the track to try and get in some laps on the slicks before the rain arrived. - REUTERS
