Fog?

Travel arrangements sorted... need to nip and get the grub this evening...it'll be too early tommorrow... looking for a 09:30 ish departure from Ramsgate... and with a 3 hour drive to get there its an early start.... Only real concern however is Fog in the forecast.... At least its 'fog banks' for the south coast, and only 'fog patches' for Thames Estuary..... I guess it'll be 'suck it and see' in the morning....
