,Fire is burning in litter on top of the ground, but occasionally
carries into the crowns of individual trees, which produces
burning embers that start new fires outside the fire perimeter.
- ANSWER >>>>Surface fire with torching and spotting.
Fire begins burning into the crowns and spreads through the
canopy. There is a sudden increase in fireline intensity where
the fire controls it's environment. At one point flames can be
seen carried high into the convection column with a whirling
motion. - ANSWER >>>>Ground fire with smoldering and
flare ups.
