Rating Definitions
A low danger rating means fire can start easily and spread quickly, but there will be minimal involvement of deeper fuel layers or larger fuels. Open air burning is permitted by permit only.
A moderate danger rating means forest fuels and ground vegetation are dying and there is an increased risk of surface fires starting. Open air burning is permitted by permit only.
A high danger rating means forest fuels and ground vegetation are very dry and the first risk is serious. New fires may start easily, burn vigorously, and may challenge fire suppression efforts. Open air burning is permitted by permit only.
An extreme danger rating means extremely dry forest fuel and ground vegetation. The fire risk is very serious. New fires will start easily, spread rapidly, and challenge fire suppression efforts. Open air burning is prohibited and permits are suspended.
