Wild Fire Risk
MODERATE FIRE DANGER IS FORECAST
Fires can start from most accidental causes but, with the exception of lightning fires in some areas, the number of starts is generally low. Fires in open cured grasslands will burn briskly and spread rapidly on windy days. Timber fires spread slowly to moderately fast. The average fire is of moderate intensity, although heavy concentrations of fuel, especially draped fuel, may burn hot. Short-distance spotting may occur, but is not persistent. Fires are not likely to become serious and control is relatively easy.

FIRE DANGER CODES (FFDC, SFDC, GFDC)


The FWI is further refined into indices that represent the Fire Intensity likely in the three vegetation types (Forest, Scrub & Grasses). These three codes are divided into five fire danger classes (Low, Moderate, High, Very high & Extreme) and calculate the fire intensity in kilowatts per square metre (kw/m^2).

FOREST ................ HIGH, (1207)
Based on predicted generated "fire intensity (kw/m^2)" in highly flammable forest type vegetation (conifer, eucalypt). This code denotes how difficult it would be to control a fire in this vegetation type should one start.
SCRUB ................. EXTREME, (8625)
Based on predicted generated "fire intensity (kw/m^2)" in flammable scrub type vegetation (tea tree, broom, gorse, manuka). This code denotes how difficult it would be to control a fire in this vegetation type should one start.
GRASS.................LOW, (0)
Based on predicted generated "fire intensity (kw/m^2)" in grass type vegetation (dry grass, tussock). This code denotes how difficult it would be to control a fire in this vegetation type should one start.
