Last year 4.4 million[1] acres burned in CA (~4% of the state), and 1.2 million[2] in OR (~2% of the state). These are huge numbers. Similar to CA, it's not just the acreage significantly increasing in recent years but also intensity and damage. The Almeda Drive Fire destroyed over 2,000 structures between Ashland and Medford, in highly accessible terrain with firefighting resources nearby.
Right now, the Bootleg Fire in Oregon is over 150,000 acres with 0% containment [3], putting it within the top 20 largest fires in state history at present and likely to grow.
From my layman's perspective, it seems that the brief window when CA's ideal climate moves slightly north has already come and gone.
