evidence: Many residents are unaware they are now at risk because federal and state wildfire forecasts and maps also haven’t kept pace with the growing danger to their communities. Indeed, some wildland fire forecasts model urban areas as "non-burnable," even though the Marshall Fire proved otherwise. The disaster put an exclamation point on what scientists, planners and federal officials warned for years: Communities outside the traditional wildland-urban interface, or WUI, are now vulnerable as a changing climate, overgrown forests and explosive development across the West fuel ever-unpredictable fire behavior. Fire experts define the WUI, pronounced woo-ee, as areas where plants such as trees, shrubs and grasses are near, or mixed with, homes, power lines, businesses and other human development. [...] The city had done the same in 2002. With smoke still in the air following the Hayman Fire — which started about 35 miles northwest of the city and destroyed 600 structures — a coalition of fire officials, homeowners’ associations and local builders and roofing contractors devised rules that banned wood roofs on all new homes and repairs greater than 25% of the total roof area.
