Getting enough water to a fire could problematic. Access to remote areas, particularly in mountainous or heavy undulating terrain will also be difficult. Are there roads to such areas and are they in good condition. The rotation and rest of fire fighters is critically important.

Weather conditions are critical: air temperature (particularly wet bulb temperature), wind speeds and directions, moisture content or dryness of the air, the possibility of the formation of fire tornadoes or pyrocumulus cloud.

Weather conditions during the preceding years also important, particularly if it encourages the growth of new forest vegetation, particularly undergrowth. If conditions are too favorable too much dry undergrowth can develop. The only way to remove it is by controlled burning during wetter, cooler periods. Knowing if such conditions exist requires monitoring.

One of the unpleasant realities of fires on such a scale as they currently are in Canada is humans cannot extinguish the conflagration. Humans can attempt to prevent fires from escalating. Fires on such a scale are extinguished by either wet weather or they just burn out by running out of fuel.

The hard work of containing a fire is done on the ground. You have to cut fuel breaks and do back burns so that the fire stays within a controlled perimeter and doesn't grow. You also need experienced staff. This is life and death work with very difficult physical demands, so you can't just "hire more people" one day when fires get out of hand. When it gets bad across the region, fire fighters from other countries will be brought in to help.

In general, decisions are made during wildfire season to focus resources that "extinguish" fires on threatened developed land and residences; because they are accessible and government wants to minimize property loss and loss of life. The reality is that when it is wildfire season, we are waiting for the next rain event to do the work of extinguishing the fire. In the meantime there is focused extinguishing efforts on protecting human life and property and containing fires that are accessible. Please support federal land managers and fire fighters.
