California Wildfires By the Numbers

It’s been a busy year for California wildfires. To date, The Northern and Southern California Geographic Area Coordination Centers have reported a total of 7,541 fires for 783,968 total acres burned. To put it in perspective, that’s larger than the entire state of Rhode Island… burned.

 Let’s have a look at the previous five years as reported by the National Interagency Fire Center (NIFC):

The previous five year average was 8,055 fires for 447,740 acres burned. And while California is a bit under the average this year, it’s only mid-September, and US Forest Service officials are expecting to see fire activity until at least November.

 

Fewer fires but more acreage can only mean one thing, larger fires. This year California has seen six fires over 50,000 acres in size, with four of those still actively burning. Again, let’s have a look at the previous five years as reported by NIFC:

The previous five year average was approximately one large fire per year in California. With so many large fires this season, firefighting resources have been stretched thin. Not to mention that California has sent equipment and manpower to other states that have also been impacted by wildfires this year.

Rain Not Always Welcomed Forecast for Wildfire Scorched Areas

As the Valley Fire in Northern California continues to burn, the forecasted rain can help and hurt.

The Valley Fire north of San Francisco, CA has burned 70,000 acres and is 30% contained. Active fire and visible flames still cover a lot of the area, and the rain expected today will likely help firefighting efforts to cool and douse these parts of the fire. However, for the areas already scorched by this blaze, like Middletown, with burned, unprotected soil, the rain brings further concerns of landslides and flash flooding.

Many variables lead to increases in risk for an area for landslides and flash floods. One such consideration is recently burned areas that have little to no vegetation to hold the soil in place and minimize erosion. Another notable fire in Northern California is the Butte Fire (71,780 acres, 45% contained) near San Andreas which is also in areas of mountainous terrain. This increased slope is another concern after a wildfire when rain approaches.

Images like the one seen above (taken by a RedZone Liaison on the ground near the Valley Fire today) are becoming common as large wildfires continue to burn across the Western US and Alaska this fire season. Many show no signs of being contained until snowfall.

 

USA Wildfire update – 206 and counting

Alaska remains the unfortunate leader in wildfire, with more than 1.2 million acres involved in 17 major fires. RedZone is currently tracking 30 wildfires in Alaska.

As a comparison, the twenty largest fires in the Continental US combine to measure 382,000 acres – barely a quarter of the size of the Alaskan fires.

Within the CONUS, California has two of the five biggest fires: the Happy Camp Complex fire in Klamath National Forest at 134,000 acres, and the Lake Fire in San Bernardino National Forest at 31,000 acres. RedZone is currently tracking 18 wildfires in California, with varying levels of intensity and threat.

There are other significant fires in Oregon, Washington, and even New Mexico and Nevada. If you want reliable, timely intelligence on wildfire, turn to RedZone. For more information, visit our website at www.redzone.co.
