With temperatures climbing above 90 degrees this week in Jackson and Josephine counties, the Oregon Department of Forestry is ramping up the fire danger level from moderate to high beginning Friday.

With temperatures climbing above 90 degrees this week in Jackson and Josephine counties, the Oregon Department of Forestry is ramping up the fire danger level from moderate to high beginning Friday.

That means increased restrictions for outdoor activities, including operating chain saws and other motorized equipment on the 1.8 million acres of state, private, county, city and U.S. Bureau of Land Management lands protected by the department's Southwest Oregon District.

Coincidentally, Friday marks the 10th anniversary of the start of the 2002 lightning-caused Biscuit fire, which burned nearly a half-million acres in southwestern Oregon.

"Compared to Colorado and the Southwest, we are relatively in good shape," said veteran firefighter Brian Ballou, a spokesman for the district. "Our trees are still saturated."

The National Weather Service reports that 5.38 inches of rain were recorded at its weather station at the Medford airport during the months of April, May and June, much higher than the average 3.31 inches for that period during the two decades ending in 2010.

Meteorologists note this is the third consecutive spring in which rainfall, along with slightly cooler temperatures, have prevailed in the region. That includes 5.45 inches of rain in spring 2010, followed by 5.01 inches the following spring.

Yet, thanks to limited winter precipitation, the rainfall for the period from Sept. 1 remains slightly below average at the Medford weather station.

And the recent hot temperatures are quickly drying the region, increasing the fire danger, Ballou said, adding that high fire danger by mid-July is not unusual.

Meanwhile, a cooling trend in Colorado and the Southwest means that many firefighters and equipment deployed there from this region have returned, he said.

"We've had some folks sent to far-flung places to fight fires, down to New Mexico and other places. They are back now," he said. "The normal monsoons they are having in the Southwest now is good news for all of us."
