There’s bad news ahead for already terrible wildfires in the U.S.


The flames scorching the Western U.S. aren’t expected to relent anytime soon. 

The National Oceanic and Atmospheric Administration (NOAA) gave its monthly U.S. climate report on Thursday, and they used the opportunity to show that the next couple of months are ripe for an enhanced fire risk out West.

After noting the exceptionally hot and dry conditions that stoked destructive wildfires so far this summer, Tim Brown, director of the Western Regional Climate Center, said in a press call that it won’t be until after October that “we see a decline in significant fire potential.”

A critical driver of this heightened fire potential is that trees, grasses, and shrubs, known collectively as fuels, are currently “flirting with all-time record lows for fuel moisture,” said Brown.

In short, hot temperatures and multiple heat waves this summer have parched the land to extreme levels, turning it to tinder. Meaningful rains can solve the problem, but they don’t usually show up in many portions of the West until November. 

What’s more, the coming fall months have another potent fire factor that isn’t usually seen in August: Strong offshore winds, blowing from the northeast. 

Called “diablo winds” in Northern California, these gusts are hot, dry, and fast and have historically whipped up fires.

Case in point: The deadly firestorms that swept through Northern California neighborhoods last summer were stoked by October’s diablo winds.

On top of all this, Brown underscored that since 1895, there has been a trend in increasing temperatures at night, which ultimately won’t allow fuels to cool off and recover. 

“This can lead to longer fires and more smoke production,” he said.

But in the last couple decades, “this trend has taken off,” said Brown. 

Taken alone, each of these environmental conditions can stoke fires, but taken together, they invite major flames. 

Some of the largest fires in California history are burning through the ravaged state right now, and smoke from both the Western U.S. and Canada has traveled thousands of miles away to the Atlantic Ocean, actually engulfing a cyclone

Brown likened the profoundly parched vegetation in the West to a dying Christmas tree. 

During winter, the tree might be wet and green, but as time passes and the leaves brown, it becomes an increasing flammable object.

And unfortunately, that’s how we all should be thinking about the West right now.
