How is fire danger determined?
Similarly, how is fire danger calculated?
Fire danger The FDI is a calculated using the degree of fuel curing, the air temperature, relative humidity, and wind speed for a given day. Fire Danger Index (FDI) is estimated using the McArthur Fire Danger Meter for grasslands or forest. The higher the FDI, the higher the fire danger.
One may also ask, how does humidity affect a fire? Relative Humidity Moisture in the form of water vapor is always present in the atmosphere. And - the amount of moisture that is in the atmosphere affects the amount of moisture that is in the fuel. The lower the relative humidity, the more readily a fire will start and burn; the more vigorously a fire will burn.
Likewise, what do the fire danger ratings mean?
The Fire Danger Rating is an indicator of how dangerous a bushfire could be if it did occur. It is not a predictor of how likely a bushfire is to occur. It should be used as an early indicator to trigger your plans. The higher the Fire Danger Rating, the more dangerous the fire conditions.
