Proud of my Big Local Class this fall and the work this team did examining costly forest fires -- want the data and an analysis guide? Hit me up!
Analysis by students in our @BigLocalNews class has found California dwarfs other states in fire-suppression costs. And dense development at the border of wildlands helps explain California fires’ exceptional damage and expense to put out. peninsulapress.com/2018/12/1…

These fires are nowhere near contained, and there’s a lot we don’t know about their extent, where they began and what has been lost. 18/

The #Atlas fire began in an area that hasn't seen fire since 1981. CAL FIRE has no recorded fire history where the #Patrick fire began. 17/

Another exacerbating factor: The fires are burning in areas that have not seen fire for decades. 13/

..But more people living in these areas means a greater chance for fire. Humans cause as much as 90 percent of wildfires. 12/

Nationwide, about 8.5 million homes have been built in these areas since 1990. Not only are there more homes at risk of burning… 11/

The shaded areas on this map show WUI zones in the area: where buildings are intermixed with forest. 10/

Another risk factor is that much of the area is in what’s called the Wildland-Urban Interface, or WUI. 9/ apps.revealnews.org/wui/

Wide swaths of Napa/Sonoma are rated as having moderate to very-high fire severity - where the chances of destructive fire is highest. 7/

It’s not unusual to have wildfires this time of year. Fire season is now year round here. But these spread quickly with little warning. 4/
