Forest fire danger
From summer 2021 MET has used a new method for calculating the risk of forest fires. We are now calculating the risk throughout the country and not just for some selected locations.
The new forest fire danger index can be found here (Norwegian only): skogbrannfare.met.no
The new method is based on the Canadian Fire Weather Index, but adapted to Norwegian areas, and can give us a better warning of forest fires (https://www.met.no/vaer-og-klima/ekstremvaervarsler-og-andre-farevarsler/vaerfenomener-som-kan-gi-farevarsel-fra-met/varsel-om-skogbrannfare).
Key weather parameters are air temperature, humidity, precipitation, wind and snow. With the exception of wind, all of these parameters have been used in the past as well. By using wind, we can estimate the risk of spreading, in addition to the fact that wind is also important when the vegetation dries.
