The Fire Weather Index shown on this web-page follows the Canandian Fire Weather Index CWFIS and is based on weather data from the global weather model ICON, provided by the Germany Weather Service, DWD.

The Fire Weather Index is composed of six indices:

FWI	Fire Weather Index, provides a rating for fire danger. It combines five components FFMC, DMC, DC, ISI, BUI that account for the effects of fuels and weather conditions.
FFMC	Fine Fuel Moisture Code, is a rating of the moisture content of litter and other cured fine fuels, like needles or twigs less than 1 cm in diameter. FFMC is representative of the top litter layer 1-2 cm deep and has a short-term memory, only reflecting weather conditions that have occurred over the past three days.
DMC	Duff Moisture Code, indicates the moisture content of loosely compacted organic layers with a depth of 5-10 cm. DMC fuels have a slower drying rate than FFMC fuels.
DC	Drought Code, reflects the moisture content of compact organic layers, 10-20 cm deep. DC is indicative of long-term moisture conditions and deep burning fires, being related to mop-up and patrol difficulties.
ISI	Initial Spread Index, adds wind speed as a good indicator for fire spread.
BUI	Buildup Index, is a weighted combination of the DMC and DC indexes and represents the total fuel available for the spreading of fire.
