SEATTLE — Predictions of an early wildfire season have come true in the Northwest as low snowpack levels, record warm temperatures and very dry conditions have helped fuel blazes weeks earlier than usual.
Fires have destroyed more than two dozen homes and torched 30 square miles in Washington, as well as burned about 60 square miles in Oregon so far this year, according to the National Interagency Fire Center.
“Although typical for later in the season, it’s really early to get these big fires,” said Coleen Haskell with the fire center’s predictive services in Boise, Idaho.
June brought searing temperatures to many parts of Washington and Oregon, drying out already parched grasses, shrubs, trees and other fuels and increasing their potential to ignite.
Many areas in the region had their warmest June on record.
“It just makes the fuel that much hotter and takes less energy to start a fire,” said Colin Robertson, a fire behavior analyst for the state Department of Natural Resources.
The earlier fires are extending the season by an extra three weeks to a month, Haskell said.
So far this year, there have been more than 300 small and large fires in Washington and Oregon.
By June 22, there were 321 small and large fires in Washington, compared to 224 for the same period last year, according to DNR.
The fire center’s July 1 forecast called for above-normal wildfire danger in the Northwest for July through September.
The forecast also said that large trees and logs are currently as dry as they would typically be in August.
Lightning in May caused a fire in the Queets River valley in Olympic National Park, known as the Paradise Fire.
The fire area experienced its driest spring since 1895, and precipitation from January until June was less than 10 percent of normal, said Donna Nemeth, a spokeswoman for that fire’s response.
It was the driest May and June since 1895 all along the North Olympic Peninsula, and officials pleaded with the public to avoid using consumer fireworks on the Fourth of July weekend.
Following a lack of snow and a dismal mountain snowpack in Washington and Oregon this winter, shrubs, grasses and trees are holding less moisture, drying out earlier and are thus much easier to ignite, fire experts say.
But the low snowpack is only one of the ingredients needed to create fire, said Dave Peterson, a research biologist with the U.S. Forest Service’s Pacific Northwest Research Station.
And the reduced snowpack isn’t the most important.
“You need to have fuels that are flammable. You need to have a period of warm dry weather, and you need to have an ignition.”
Peterson said he wouldn’t link these early-season fires, or any fire, to climate change.
“However, we will almost certainly see more early fire, more late fire, and more area burned as the climate continues to warm,” he said.
“If this is going to be the new normal decades into the future as the climate warms, it will be more difficult to resist it,” Peterson said.
“It probably makes more sense to adapt to it.”
