The distributions of the fireline intensities at windspeed and at a 2 mi/h 

 windspeed and slope are given in figure 6. A prediction of the intensity from 

 uniform fuel properties is again presented for comparison, similar to the presenta- 

 tion of the rate of spread prediction. The average intensity of the uniform model 

 lies 4 3 percent above the nonuniform model at mi/h windspeed and 29 percent above 

 at 2 mi/h. Both distributions decrease monotonical ly with increasing intensity and 

 are bounded on the low side by intensity. The upper limit is 6 times the nonuni- 

 formity model average at mi/h windspeed and 7 times that average at 2 mi/h.
