(Durkee, OR) -- Crews continue to battle the Durkee Fire southeast of Baker City after the blaze jumped I-84 yesterday.

I-84 has been intermittently closed because of the fire. A severe thunderstorm moved over the area Wednesday afternoon, bringing many lightning strikes that may have caused more fires. More than 817-thousand acres are currently burning in Oregon.
