>>1398549 During the worst part of the fire season in southern California, strong Santa Ana winds were observed to blow carpets of burning embers across eight-lane freeways.[citation needed] During the 1988 fires in Yellowstone National Park, hot embers managed to cross the Lewis Canyon, a natural canyon up to a mile wide and 600 feet (180 m) deep.[citation needed] In Australia, firebreaks are less effective against eucalyptus forest fires, since intense fires in tinder-dry eucalyptus forest spread through flying embers, which can be carried by the winds to trigger new blazes several kilometres away.[3]
