Most El Nino winters are followed by a dry spring. This would portend earlier snow melt and fuel availability. Highly responsive fine fuels available over wider area. Fire season begins up to 2 weeks earlier than usual. Most noticeable on the west side. Thus, longer than typical fire season in 2010.
El Nino not a good indicator of fire season weather patterns in the PACNW. Number and intensity of lightning episodes drives fire activity.
