Wildfires can occur anywhere where there is adequate heat, oxygen, and fuel. Anywhere it's dry hot and windy.Wildfires can occur anywhere where there are miles of trees and the weather conditions are dry.

Conditions become unfavorable for one summunity and favorable for another
Freak Weather Conditions (or Extreme Weather Conditions) are when weather conditions that are unusually severe occur. It could also apply to weather conditions that are unusual for the part of the world they occur in, or the time of year they occur at. For example, a large tornado that causes a lot of damage would be a Freak Weather Condition for England, because we don't tend to get many tornadoes here, and those that we do get rarely get more severe than an F2.
