Operational Awareness for Advanced Firefighters & Fire Behaviour Analysts


If a low-level jet watchout is issued by the Planning Officer in consultation with the Operations Officer, Sector Leaders working on high ground need to be wary and must monitor fire weather at thirty minute intervals (using a hand-held weather monitor or portable AWS). Any significant changes in fire danger should be discussed with the Operations Officer immediately.
If a low-level jet causes a Red Flag Warning to be issued, it will be on the basis of conditions conducive to the formation of a plume-driven fire. It will be issued by the Planning Officer in consultation with the Operations Officer, all Operations staff and especially Sector Leaders should then review safety needs. The Operations Officer would need to ensure that fall-back IAP elements are at hand to activate immediately should a sudden change in conditions occur.
