Expert Awareness for Advanced Firefighters & Fire Behaviour Analysts
The spread of the fire is easy to predict using established fire spread meters, algorithms or spreadsheets. The rate of spread, intensity, spotting potential and ratio of fire length to width are useful parameters. Guidance on that ratio can be derived from Pasquill’s Index.
Reliable local weather observations are often not available. However the lack of terrain modifiers in flat terrain for weather make it valid to extrapolate from the nearest “official” weather sources or to use BoM NexGen gridded data.
