Fuels &
Fire
Behavior
• ISIs show that spread & ignition potential
are low/moderate statewide; strong winds
in NE Interior raise some potential there.
• DMCs indicate the upper and mid layers
of duff are too wet to carry fire; surface
spread is the likely fire type.
• Spruce Adjective shows only isolated
stations that have any elevated potential,
and at this point in the season, not
enough drying can occur to bring bigger
fuels back to burnable.
