A fuels and fire behavior advisory is in effect for SE Oregon below 5500 ft. Fine fuel loading is above average. Live fuel moistures are below 100 percent making them seasonally ahead of norms. Thunderstorms and gusty outflow winds combine with the above average fine fuel loading for another day of potentially extreme fire behavior. Hot and dry conditions continue. Extended burn periods are resulting in extreme fire behavior.

Significant Events

Moderate 

Backing 

Creeping 

Smoldering

Wind and fuels driven fire moving at low to moderate rates of spread due to successful lsuppression actions.

Current Weather
Weather Concerns

Wednesday morning began with thunderstorms over the fire. 
Thunderstorms were dry, with no measurable precipitation 
recorded. A number of cloud to ground lightning strikes were observed, mostly on the north and southwest sides of the fire area. The thunderstorms also brought gusty outflow winds as high as 25 mph. Highs in the afternoon reached near 100 degrees as relative humidities fell to 12 to 16 percent. 
 

Thunderstorms are not expected on Thursday as the upper level ridge of high pressure builds in even stronger. Temperatures will continue to climb through the weekend, with high temperatures reaching as high as 108 degrees by Saturday. Hot and dry conditions will continue through early next week with high temperatures 106-108 degrees and minimum relative humidity 10 to 12 percent each day. Wind directions will be variable, but gusts should remain 20 mph or less except over ridgelines.
