but part of the challenge is these fires are creating their own wind environments. so what's going on is the weather service issued a red flag warning in and around the carr fire which is very unusual to put it in just a localized area because they say the wind produced by the fires themselves will help cause the fires to spread. and add one more factor to this. air quality is dropping. a bunch of air quality alerts are in effect for southern sections of oregon and most of the sand jauquin valley because of the problems. we showed you earlier some of the fantastic video of what people describe as a fire nado. there is a way we can describe and explain how that happens and how we get something like a fire nado. we are going to go to the 3-ds elements and show you the factors. whenever you have a fire occurring well you are going to allow the heat to rise rapidly.
