El Nino Status as of March 5th 2015:ENSO Status: El Nino Advisory

“In summary, there is an approximately 50-60% chance that El Niño conditions will continue through Northern Hemisphere summer 2015. Due to the expected weak strength, widespread or significant global impacts are not anticipated.” -from March 5th 2015 El Nino Diagnostic Discussion

NWCC Predictive Services outlook :

May 2015

The Northwest Geographic Area is out of fire season. Fire danger indices are not sufficiently elevated to support unusual risk of Significant

Fires in the region. Even during spells of dry weather, conditions in April and May are historically not conducive to large, costly

wildfires.

Page 17: Northwest Geographic Area Coordination Center Predictive Services Spring and early Summer 2015 Climate and Significant Fire Potential Outlook Wednesday

NWCC Predictive Services outlook :

June and July 2015

Elevated risk of large, costly fires (mainly from lightning) is expected to expand northward from California into Oregon and Washington in June

and cover most of the region by July. This designation of elevated Significant Fire risk is based on warm temperatures, low snowpack,

and early greenup.

NWCC Predictive Services note :

Due to poor snowpack at higher elevations and generally dry conditions since the first of the year, fire management units are advised to use caution during

prescribed burns in windy weather.
