"At this time, there are no towns, subdivisions or structures under immediate threat of evacuation.," the update stated.

But county officials renewed their warning to residents south of Sisters on Saturday to be ready to leave quickly, noting that the still-growing fire was butting up against several "evaluation lines" in the area.

Dozens of Sisters area residents packed into the elementary school Saturday morning for a briefing on the fire and what challenges the crews are facing. A fire meteorologist, fire behavior specialist and safety officer spoke to the crowd.

The Palmer family has lived in the area for about a year and half, and this is their first big fire threat they've seen.

"We live really really close to it, and there's a lot of smoke, "said Jason Palmer. "The ashes are falling on our house, and the kids can't really breathe."

The Palmers are one of many families who are on level two pre-evacuation notices.

"So if we need to just take all of our dogs and our stuff, we're just going to go," Palmer said. "We're from Central California, and we don't get stuff like this. So it's a little different. It's kind of scary."

The Deschutes County Sheriff’s Office conducted another Level 2 pre-evacuation alert on Saturday through a recorded Emergency Phone Notification utilizing the reverse 9-1-1 system.

They reminded citizens to be prepared to leave at a moment’s notice. The alert went out to the areas of Crossroads, Edgington and Remuda Roads and the south side of the city of Sisters.

This Level 2 pre-evacuation alert was initiated due to "increased fire behavior that has occurred over the past 24 hours and to remind citizens they should remain highly vigilant during these situations," said the Saturday afternoon statement.

The sheriff’s office has continued to work closely with the Oregon Incident Management Team 4 on the latest fire status, they said.

Fire crews in the region scrambled to several small new fire starts Friday night after dry lightning peppered the area, while ash fell over a far wider area than the smoke itself, including Bend and Redmond.

Officials warned drivers could expect areas of limited visibility on highways 20, 126 and 242. Hwy. 242 (the McKenzie Pass Highway) was closed for a few hours Saturday morning for firefighters to access the blaze. It was reopened by mid-morning, "subject to intermittent closure," according to ODOT.

For firefighter and public safety, the large closure area was modified Friday to include a portion of the Pacific Crest Trail (PCT) between Trail #3531(Four in One Cone) and the PCT Trailhead on Highway 242.

Information will be posted at all trailheads and access points from Elk Lake Trailhead north to Santiam Pass. PCT hikers will have a reroute options.

The closure still includes Forest Roads 15 & 16 (Three Creeks Rd); spur roads, trailheads and the Three Creeks Campground area. It now also includes an extension of Forest Road 370 to Forest Road 4601.

Closed roads are signed, barricaded, and/or staffed to advise the public of the closure. Closure maps and area descriptions are available at Deschutes National Forest offices as well as http://inciweb.org/incident/3244/.

In a rare voluntary health advisory, Deschutes County health officials have advised residents to "shelter in place" and seal their homes as best as possible during the worst of the smoke in the overnight and early morning hours.
