A secondary objective of this work was to test some of those methods and evaluate their limitations for forecasting meteorological data involved in the fire danger evaluation in an extensive territory. In the Andean region of Patagonia where this study was conducted, the interpolation methods to obtain a continuous set of reliable meteorological data necessary for the daily evaluation of fire danger have produced dissimilar results.  The difficulties in applying interpolation methods were not only related to the scarcity of meteorological stations, but also to the location of every station, which produced punctual data that represented valid meteorological values only in a small fraction of the terrain around that station.
