The National Interagency Fire Coordinating Group has moved to national Preparedness Level 5 as of Tuesday. That’s the highest alert level the nation has seen since 2008. Preparedness Levels are based on burning conditions, fire activity, predicted weather and resource availability. They indicate the overall current and expected fire activity on a national or local basis. The levels range from 1 (minimal activity) to 5 (very high activity). Other considerations for a Level 5 include the potential to exhaust all agencies’ fire resources, 80% of Type I and II crews being committed, as well as the majority of other resources, and significant fire potential that is likely to remain high in at least three Geographic Areas for seven days. Officials at the National Interagency Fire Center say the emerging fires in California and the Northern Rockies, plus continued high activity in Idaho and Oregon, helped prompt the change.
