Following record rains this past winter, the annual southwestern monsoon season is generating above average lightning activity in thunderstorms that occur on a daily basis. The lightning has been the principal cause of the 21 fires recorded in the park since June (burning a total of over 76,000 acres). The storms have also caused numerous downpours and flashfloods. Entire roads within the park have been washed out, repaired, then washed out again by subsequent flood waters. Recently burned areas are receiving flash floods on a daily basis. In order to mitigate the cycle of impacts, numerous fire and law enforcement personnel from neighboring NPS areas have been brought in. Although all documented records of fire occurrence have been greatly exceeded this year, the worst of the fire season is usually the later part of the summer, when Santa Ana winds start prevailing.
