'''NOTE: This Fire Weather Index is an original development and bears no relation to any other existing fire weather index and the resulting (absolute) value can not be compared to any of those. It is the resulting warning level which can be compared and which should be used.'''


The Fire Weather Index for a personal weather station, in short '''pwsFWI''', is probably one of the most complex modules of ''CumulusUtils''. Not so much for the calculations, which once you know what to do are not that complex, but more for the interpretation and understanding of what is shown. This Wiki article will try to explain both how the module works, what you get and the value of it.

On my (HansR) blog you may read [https://meteo-wagenborgen.nl/wp/tag/pwsfwi/ several posts] on the pwsFWI but also on the other fire weather indices in the world notably [https://meteo-wagenborgen.nl/wp/2019/08/11/fire-weather-the-canadian-fwi/ the Canadian FWI]. This complex FWI is used in many places but it is so complex that it is not summarized in equations, but referenced by the articles. The complexity of this FWI was one of the main reasons to create pwsFWI.
