*"Matrix Fires" is a best-effort guess at currently active, significant fires -- reported acreage above zero, containment reported and strictly between 0% and 100% (excludes brand-new 0%-contained reports, fully-contained fires, and anything with no containment figure at all), started within the last 30 days, and last updated within the last 3 days (loosened slightly from a stricter cutoff to allow for incident teams not posting updates over a weekend). It is not an official designation, and fires that don't happen to report every one of those fields will be left out even if they're genuinely active.
