What do the colourful signs on the sides of the road mean?
The ‘colourful’ signs indicate the current fire danger. The FDI or Fire Danger Index is a widely used scale to illustrate the fire danger for any given day. It is based off a numeric scale, estimated using the McArthur Fire Danger Meter (and subjective consideration). The McArthur Fire Danger Meter takes into account 4 main factors: Curing (How dry?), Temperature, Humidity and Wind. High Temperatures, High Winds, High Curing Levels and Low Humidities present days of greater fire danger. The indicated colour (or level – low, moderate, high, very high, extreme) gives a relative guide to the fire danger for any given day.
