Some fans planning to attend Saturday's qualifying for the British Grand Prix have been advised to stay away from Silverstone following heavy rain.
The treacherous conditions caused havoc on Friday as the teams struggled with their cars on the tracks.
"Unless spectators have PRE-BOOKED park and ride or are in local campsites and able to walk to the circuit we strongly advise that they do not attend the qualifying day of the 2012 Formula 1 Santander British Grand Prix," read an official Silverstone statement.
"The reasons we have taken this action is due to the fact that we have lost some of our car parks today in the awful wet weather that we have suffered over the last weeks, and, in particularly, the last 36 hours. We must do our very best to protect as much of our car parking as possible ahead of Sunday.
"Fans will be refunded for any unused Friday or Saturday tickets and full details on how this will be handled will be communicated early next week."
The bad weather is expected to continue throughout the weekend.
