There are fears that the Hungarian Grand Prix weekend may not go ahead as planned after new footage of the Hungaroring circuit emerged online.
The race has been staged on the F1 calendar every year since 1986, with Lewis Hamilton the most successful driver in the history of the circuit with eight wins to his name.
One issue that often befalls the circuit, which has a contract to host F1 races until 2032, is bad weather, with races sometimes being affected by rain.

However, that bad weather has been taken to the extreme in recent days - with new footage showing the section of track surrounding the pit straight - the highest point of the track - in worrying condition.
The pit lane itself had been submerged by rain on Thursday evening, with the water above ankle height at some parts of the straight.
That weather, combined with heavy winds, has wreaked havoc at the Hungaroring, with the roof of McLaren's motorhome in the paddock even being ripped off entirely.
While weather conditions are improved on Friday, Saturday and Sunday, with clear skies and warm temperatures, there is another thunderstorm forecast for Thursday evening that could cause further issues.

That could cause Friday's practice sessions to be at risk, which would add another challenging element for drivers and teams ahead of the 70-lap race on Sunday.
F1 are yet to release an official statement on whether Friday practice will go ahead, with a decision likely to be made on the day if necessary.
F1's official website, meanwhile, claims that Saturday and Sunday both carry a chance of rain, with a 20 per cent chance of rainfall expected for Sunday's race.

That forecast may suit McLaren in particular, who looked to have the quickest car in wet conditions during the British Grand Prix at Silverstone.
That race was eventually won by Lewis Hamilton, with Mercedes having won the last two races following George Russell's success at the Austrian Grand Prix.
The Drivers' Championship is led by Red Bull's Max Verstappen, who is 84 points clear of McLaren's Lando Norris having won seven of the opening 12 races of the season.
