The organisers of the British GP have apologised to fans unable to get into the circuit today to watch practice for this Sunday's race.
Heavy rain has led to traffic chaos and in a statement issued via Twitter, just before the start of free practice 2, organisers added that one of the 'major problems' is people heading to camp sites that have not pre-booked places.
“To all who are stuck in traffic, we are trying our best to get everyone on site,” read the blurb on Twitter. “We have a major problem with traffic going to campsites along the Dadford Road which are full, if you have not pre-booked please DO NOT attempt to camp at these sites.
“Those of you that are here already we are doing our best to relocate you. If you are stuck in traffic we are doing all we can to get you in and parked up asap, we are sincerely sorry for the delay.”
A statement on the official Silverstone website added: “There are traffic delays on approach to the circuit and the adjacent road network. This is as a result of the unprecedented wet weather which means we are taking longer to park cars safely and position campers.
“Please be patient, we are doing all we can to improve the situation.”
Silverstone sent a warning to all ticket holders on Thursday about the weather.
It read: “The unprecedented recent wet weather is having an adverse impact on our car parks and on campsites in the area. A number of Blue Ribband events have been seriously affected by the wet weather conditions. We are planning to avoid a similar situation.
“Each year Silverstone invests over £1 million pounds preparing and managing our car parks and traffic. Silverstone has the top traffic management experts in the business on site advising on our wet weather plans. They have vast experience from other large UK events and festivals.
“In the weeks and months running up to this weekend we have taken pre-emptive actions, including:
*An extra mile of filter drainage has been put in
*2 x 4,000 gallon tankers have been brought in to aid with water removal
*1,100 tonnes of hardcorehas been brought in
*A fleet of plant and machinery and teams of workmen have been working around the clock on roadways
“We have prepared the site to cope with the weather as best we can. Despite our efforts, some of the grass car parks are very wet and there is currently an amber weather warning in force in our region.
“Fans have been kept informed of the developing situation via emails and social media channels. Key messages include:
“1. Car parks open at 6.00a.m. We advise fans to arrive early as it will take longer to park vehicles safely this year.
“2. Be prepared to take instruction from marshals.
“3. We will be working to get all vehicles parked as quickly as possible. We appreciate it may be frustrating but please be patient – we will be doing our best to ensure everyone arrives safely in time to enjoy the action.
“4. We recommend tuning in to Silverstone Radio (87.7FM) for regular updates.
