'Muggy in Miami'published at 20:33 British Summer Time 4 May

Jennie Gow F1 pit-lane reporter in Miami
It's very muggy here. The crowd are a bit sparse at the moment, most people are taking shelter under the cover because it's roasting, people are fanning themselves just to get a bit of cool.
The grid sets up an intriguing race. The title contenders are in reverse order, with an interloper between Lando Norris and oscar Piastri in the form of Mercedes' Kimi Antonelli.
And Norris scents an opportunity to nail his first victory since the opening race of the season in Australia back in March.
In qualifying, he made errors at the last corner on both his laps, each time costing about 0.2secs, so he knows the pace is in the car.

Lando Norris returns to the melting pot of Miami, one year on from his maiden victory in the Sunshine State - a Formula 1 win he had been so desperately waiting for.
Last year, a well-timed safety car meant a fifth-place start turned into a champagne moment. During yesterday's sprint race, the safety car was on hand again to give the McLaren driver a helpful boost to victory.
His sprint win on Saturday has put him within nine points of team-mate Oscar Piastri at the top of the standings.

The weather forecast flipped on its head yesterday. Instead of light clouds and settled conditions, the beginning of the sprint race was lashed with rain, causing Charles Leclerc to crash out on his way to the grid and leave him unable to take part.
After a short delay, the incident-packed wet-dry race was won by Lando Norris with a leg up from the safety car. Championship leader Oscar Piastri overtook polesitter Kimi Antonelli at the first corner for the lead but the Australian had to settle for second place behind his team-mate.
Lewis Hamilton's quick thinking to pit for slicks early helped the seven-time world champion take third place. There were so many penalties on Saturday, the final points scorers ended up being George Russell, Lance Stroll, Yuki Tsunoda, Kimi Antonelli and Pierre Gasly.

There is a concern about lightning, as soon as there is any threat of lightning they will pull the cars straight off the track and they will postpone the race.

Once the madness of the sprint had died down (we'll get to that later), attention turned to a dry qualifying session where Max Verstappen beat Lando Norris to the head of the grid by 0.065 seconds.
Neither McLaren could knock down the Dutchman in the upgraded Red Bull (Verstappen has a new floor this weekend) as Oscar Piastri's attempt at a pole lap yielded fourth place. Splitting the papaya pair was Mercedes teenager Kimi Antonelli.
So had did Verstappen do it? Andrew Benson is out in Miami and in his qualifying report noted the four-time world champion's pole was secured "with a blistering first sector of the lap".
"The Red Bull's speed in the fast sweepers there was too much for McLaren to claw back in the remainder of the lap," Andrew added.

Red Bull's Max Verstappen told Sky Sports: "I do think they will have to sweep the track, there is a bit of Lego debris, a few cars collided along the way.
"It's a bit different that's for sure. I was a bit slow on top speed so we slowly dropped back throughout the lap, but I think it's more important that they clean the track at the moment."

About an hour ago, when the skies were dry, drivers had some fun taking the full-sized Lego F1 cars out for a spin.
The cars are made up of nearly 400,000 bricks, take 22,000 hours to build and reach speeds of 12-12.5 mph. "That's the most fun we've ever had in the drivers' parade," said Lewis Hamilton.

Hello, folks. It's a good job it's a bank holiday this weekend because this Miami Grand Prix could turn into a long night. The F1 Academy race (pictured above) was unable to start earlier due to the wet conditions and the Hard Rock Stadium has been lashed with rain.
If all goes to plan, round six in Miami will get under way at 21:00 BST.
World champion Max Verstappen delivered a superb qualifying lap to claim his third pole position of the season yesterday.
The new dad - he and partner Kelly Piquet welcomed a daughter named Lily this week - has the familiar face of Lando Norris starting alongside him on the front row.
