 While most of them only affect small areas, wildfire can quickly get out of control and spread across large areas of woodland, particularly when fanned by the Santa Ana winds.Hot and extremely dry, they are also known as "Devil winds", and descend on the coastal region from the continental interior of the American West, increasing in temperature as they approach the ocean.Because natural wildfires are more likely to appear towards the end of long, dry summers, they have become a more serious problem in recent years because of climate change, which makes wildfires increasingly larger and more frequent.
