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.
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.
Next Outlook:May 4th 2015
