All you say is true and your concerns are valid.
You have many resources at your disposal. Search for a local “Community Wildfire Protection Plan” and learn about it. Contact Firewise and learn how to reduce your risks. There are many Wildland Urban Interface programs that help residents with advanced planning.
It isn’t likely that you could use the Fire Brhavior tool on your own but agencies (in your case the USFS) already use such tools (lots of them, in fact) and they might be able to show you scenarios that would present the highest risks to your property.
I suggest that you contact them and make an appointment to talk with someone. That’s what I’d do, by golly.
Noted, but I am afraid I lost all confidence in the current tools available to the national agencies when that group of professional firefighters was caught in the middle of a fire not too long ago and all of them burned to death.
I hope this new software is a game-changer, and I understand from the article that there is a ‘demo’ version available for download so that it can be evaluated, so hopefully it will turn out to be a very useful tool indeed.
