Fire Danger Index Catastrophic - 100+ Catastrophic - 100+ Catastrophic - 100+ Catastrophic - 100+ Severe 50 to 74 Extreme – 75 - 99 Severe - 50 to 74 Very high - 25 to 49 Calculation of the index is based on a number of factors: Weather – drought (days since last rainfall), temperature, wind, relative humidity, soil moisture Fuels – build up of vegetation and fine fuels, fuel moisture Topography Risk of incidents – lightening strikes, human factors Very high - 25 to 49 High - 12 to 24 Moderate - 6 to 11 High – 12- 24 Lowto moderate - 0 to 11 Low - 0 to 5
Fire Danger Index Catastrophic - 100+ Catastrophic - 100+ Catastrophic - 100+ Catastrophic - 100+ Severe 50 to 74 Extreme – 75 - 99 Severe - 50 to 74 Very high - 25 to 49 Fires controllable by ground crews. Little risk to people and property. Very high - 25 to 49 High - 12 to 24 Moderate - 6 to 11 High – 12- 24 Lowto moderate - 0 to 11 Low - 0 to 5
Fire Danger Index Catastrophic - 100+ Catastrophic - 100+ Catastrophic - 100+ Extreme – 75 - 99 Fire control difficult and often fails. People in the path of a fire are unlikely to be killed or seriously injured if they take shelter. Well-prepared and actively defended homes can offer safety during a fire. Severe - 50 to 74 Very high - 25 to 49 High – 12- 24 Lowto moderate - 0 to 11
Fire Danger Index Catastrophic - 100+ Catastrophic - 100+ Fire will spread rapidly and be difficult to control. There is a possibility that people in the path of a fire will be killed or seriously injured. Some homes may be destroyed. However, well-prepared and actively defended homes can offer safety during a fire. Extreme – 75 - 99 Severe - 50 to 74 Very high - 25 to 49 High – 12- 24 Lowto moderate - 0 to 11
Fire Danger Index Catastrophic - 100+ Catastrophic - 100+ Fire control normally not possible. Rapid spread of fire. People in the path of a fire may be killed or seriously injured. Some homes are likely to be destroyed. However, well-prepared and actively defended homes can offer safety during a fire. Extreme – 75 - 99 Severe - 50 to 74 Very high - 25 to 49 High – 12- 24 Lowto moderate - 0 to 11
Fire Danger Index Catastrophic - 100+ Catastrophic - 100+ Fire control not possible nor safe. Rapid spread of fire, unpredictable. People in the path of a fire may be killed or seriously injured. Many homes are very likely to be destroyed. Only well-constructed, well-prepared and actively defended homes are likely to offer safety during a fire. Extreme – 75 - 99 Severe - 50 to 74 Very high - 25 to 49 High – 12- 24 Lowto moderate - 0 to 11
Fire Danger Index Catastrophic - 100+ Catastrophic - 100+ Fire is uncontrollable, unpredictable and fast moving. Very high level threats to life and property on a large scale. There is a high likelihood that people in the path of a fire will be killed or seriously injured. Many homes are very likely to be destroyed. Even the best prepared homes will not be safe. Extreme – 75 - 99 Severe - 50 to 74 Very high - 25 to 49 High – 12- 24 Lowto moderate - 0 to 11
