Sussex Police is advising people, who do not live locally, against travelling to Lewes Bonfire tomorrow over concerns for public safety.
50,000 people are expected to pack the streets for the celebrations.
Concerns have been raised about dangerous over-crowding at the event.
A number of roads will be closed and some train services will be cancelled on the night to dissuade people from attending.
The emergency services and Southern Railway, who are responsible for the closures, say public safety is their priority and they haven't made the decisions lightly.
