The Hewlett Fire crests a ridgeline in Poudre Canyon, northwest of Fort Collins, CO, on Monday night. The fire broke out around 1 p.m. Monday about a mile from Poudre Park, northwest of Fort Collins. The fire burned actively through the night rather than laying down as wildfires often do. By Tuesday morning it was nearly 280 acres in size, and had 100 wildland firefighters attacking it on the ground it on the ground as a single-engine air tanker and a type 3 helicopter fought it from the air. The fire, which is named for the Hewlett Gulch trailhead near where it ignited, is within a quarter mile of a number of homes, about 160 of which were warned Monday evening to prepare for a possible evacuation. The winds Monday night seemed to be blowing the fire away from the homes, but dry weather with winds forecast to blow up 15 miles-per-hour could move the fire back towards the homes.
