About 3,500 people have been out of their homes for four days due to the blaze, which was about 30 percent contained this afternoon.
No injuries have been reported. At one point as many as nine people were unaccounted for, but authorities said they have all been located.
Evacuation orders were temporarily lifted this morning for a few neighborhoods -- Boulder Heights, Carriage Hills, Pine Brook Hills and points eastward -- to allow residents to return to their homes and pick up some belongings. But returns were halted this afternoon as authorities said winds were picking up earlier than expected.
"The winds predicted will be much higher than what we anticipated this morning," Greg Heule, a Rocky Mountain Incident Management Type 2 team spokesman, told The Denver Post.
"The winds will be aligned with the fire, and those subdivisions are downwind from the fire. It's unfortunate; we hate to have to do this to them, but we need to keep them safe," Heule said.
Gusts of about 60 mph are expected later in the day and could undo much of the progress firefighters have made in fighting the blaze.
Tim Heiman, who lives in Pine Brook Hills, was able to get back home to collect a few possessions before the re-evacuation orders were issued.
"It's a second chance for getting the keepsakes stuff," he told the Daily Camera newspaper of Boulder.
The blaze has already scorched 6,365 acres, or about 10 square miles, and together with the toll of houses destroyed, that makes the so-called Fourmile Canyon fire the worst in Colorado history. The 2002 Hayman fire ravaged 133 homes.
Another $5 million is available from state authorities, after Colorado Gov. Bill Ritter declared a state of emergency earlier this week.
Authorities are investigating what sparked the fire, amid reports that a car crash may have ignited a huge propane tank.
