WebJan 31, 2024 · In this way, the moisture codes in the FWI system (Fig. 2) can be considered as integrating the weather occurring for a particular fire season up to a specific point in time. Calculating FWI system outputs over a fire season is therefore a common practice, and it is important that uninterrupted weather streams are used for multi-day calculations. WebDrought Code (DC): The potential for significant ground or sub-surface fire ac-tivity is relatively minimal at levels less than 300. However, the tendency for per-sistent smouldering increases as values of around 500 are approached in which case mop-up and extinguishment gradually be-comes increasingly more difficult as the DC continues to rise.
