What two values do you need to calculate ISI?

Direct attack will usually no longer work at this class.

What are your 3 primary outputs?

Rate of spread, fire intensity class, type of fire.

200

Occurs in summer green stage, rate of spread changes dependent on % portion of species.

Inversion

200

Organized flame front starts at this fire rank.

24M/min, intensity class 6, continuous crown.

400

I am neither leafy or naked, but right now I am leafy. Am I odd or even?

Even

I funnel flames and heat to the top and concentrate fire intensity.

Box canyon or topographical feature
