🔥 Increase Risk of Fire Conditions: Understanding “Crossover” Fire Behavior 🔥
When the temperature climbs above 30°C, wind speeds increase, and relative humidity drops below 30%, wildfire conditions can rapidly become dangerous. This is often referred to as “crossover” fire behavior — a point where heat, wind, and dry air combine to create fast-moving, aggressive fire activity.
During the next few days Humboldt will be under crossover conditions, fires can:
🔥 Spread extremely quickly
🔥 Change direction unexpectedly
🔥 Produce intense heat and long-range spotting
🔥 Become difficult to control in a short amount of time
Even a small spark from equipment, vehicles, campfires, burning debris, or ci******es can lead to a serious wildfire.
⚠️ During these conditions:
• Avoid unnecessary outdoor burning
• Use extreme caution with equipment that creates sparks
• Properly extinguish ci******es and campfires
• Keep water and firefighting tools nearby
• Report smoke or fire immediately
One careless moment can have devastating consequences for crops, pasture, homes, and communities.
Stay alert. Stay prepared. Help prevent wildfires. 🔥
