"WebWhen fire moves upslope, the fuel ahead of the flame front is closer to the flame than if the slope were flatter. This set-up "preheats" the fuels. The effects of slope on fire spread become greater as the slope increases. APPROXIMATING THE ROS. An easy guide for approximately the ROS due to changes in slope is as follows: 1. " - Flame front
