For the fire behavior, we used fuels from the Anderson 13 fuel models obtained from the LANDFIRE database \cite{landfire}, and a 100-m ignition line at (start: -105.230189, 39.956029) and (end: -105.230784, 39.956225), representing the approximate location considered during police investigations, ignited 5 minutes after model initialization. The firebrand spotting parameterization was configured with firebrands generated at every other timestep (fs_firebrand_gen_dt = 2), 10 evenly distributed vertical levels (fs_firebrand_gen_levels = 10), firebrand momentum of 6 timesteps (fs_firebrand_gen_mom3d_dt = 6), and 3-m land height corresponding to the approximate height in meters of the infrastructure in the area (fs_firebrand_land_hgt = 3).
