We've added a link for the GeoMAC web site to the Fire Information page.
GeoMAC (Geospatial Multi-Agency Coordination Group) is a site maintained by the US National Interagency Fire Center that provides real-time forest and wildfire information for the coterminous 48 states and Alaska. Perhaps the most useful part is an interactive map. Among other useful features, you can zoom into a specific area to locate active fires, their status and their extent.
