The wild fires in Central WA are at an interesting junction of getting bigger or snuffing each other out.

2 wildfires may become 1: help or hindrance to firefighters?

As Washington state's two biggest wildfires burn toward each other, fire officials say they could either feed off each other, creating a more volatile conflagration, or they could consume all available fuel and help snuff each other out.

The biggest health threat comes from the fine particles in smoke. These can cause burning eyes, runny nose, bronchitis and other illnesses. Smoky air also can aggravate pre-existing heart and lung diseases, and even lead to death.

Air filtration systems are probably getting inspected as the fire continues to burn.
