Why is the fire danger so high when it is hot out?

It isn't what you think. It is NOT so much that the air is warmer, it is that when it warms up, there is a DIRECT relationship between the Relative Humidity and the Temperature.

You see, there is a finite amount of moisture in the air, but since hot air holds more water than cold air, as theair heats up, the RELATIVE amount of water in the air goes down. Here's an example.

If you could think about the air as a cup that stretches to different heights, with a small amount of water in the bottom... imagine that the cup stretches up to a height of a foot or higher in the summer heat. You see what I mean? There is relatively very little water in that cup, once it becomes "big". Same thing with the atmosphere, that hot weather drives the humidity DOWN, way down, to 10% sometimes, and that is what sparks the brush fires.

With that in mind please think twice before doing any outdoor activity that could potentially start a brush fire.. Thank you!
