The scare attraction has been a huge hit with horror fans since it opened at the former Camelot theme park in Charnock Richard earlier this month.
But tonight's event, which included a screening of zombie horror 28 Weeks Later, has been cancelled because of the extreme weather forecast for Lancashire today.
A spokesman for Camelot Rises said: "Due to government advice to stay at home and to only travel if needed - unfortunately we've made the decision to cancel tonight's showing of 28 Weeks Later at 9pm.
