Quick Answer
In rainy weather, it's essential to create a controlled fire and maximize smoke production by using green wood, increasing airflow, and maintaining a consistent fire size. This allows for a more visible smoke signal. Aiming for a 10-15 minute signal duration is recommended.
Creating a Controlled Fire
To produce an effective smoke signal during rainy weather, you need a controlled fire that can sustain a consistent size and produce a thick, dense smoke. Green wood is ideal for creating this type of fire, as it contains more moisture than dry wood and burns slower, producing a longer-lasting smoke. Aim for a fire size that’s around 2-3 feet in diameter, with a moderate to high flame height.
Maximizing Smoke Production
To maximize smoke production, you need to increase airflow around the fire. This can be achieved by clearing a 5-10 foot radius around the fire pit, removing any leaf litter or debris, and creating a slight incline to direct the smoke upwards. Use small twigs and leaves to create a “smoke chimney” effect, drawing the smoke upwards and outwards.
Signal Duration and Timing
To ensure your signal is visible from a distance, aim for a 10-15 minute signal duration. This can be achieved by maintaining a consistent fire size and ensuring a steady airflow around the fire. Consider signaling during periods of low cloud cover or when the wind is blowing from a consistent direction to maximize visibility.
