Fire Weather Index
Recorded at Solar NoonForecast is for hottest time of day, 2-4 PM
LOW FIRE DANGER IS FORECAST Fuels do not ignite readily from small firebrands although a more intense heat source, such as lightning, may start fires in duff or punky wood. Fires in open cured grasslands may burn freely a few hours after rain, but woods fires spread slowly by creeping or smoldering, and burn in irregular fingers. There is little danger of spotting.

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 ................ MODERATE, (98) |
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 ................. VERY HIGH, (3797) |
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. |
