災害 · コーリー火災隊員らが延焼阻止線の23％を確保する中、コーリー火災の焼失面積は1,365エーカーに執筆 2026年10月20日 0:45 UTC視聴文字起こし0:07The Coulee fire covers 1,365 acres after a private prescribed burn escaped.0:12Crews have secured 23% of its perimeter, and officials report no injuries or0:16threatened structures.0:17Smoke has carried the fire's consequences beyond the burn area.0:20Investigators still have to determine why the planned burn escaped its boundaries.0:24The fire is burning west of Cloverdale, near Elkhorn Road and Cooley Ranch Road in0:28Mendocino County.0:29That's just north of the Sonoma County line and north of Lake Sonoma, where smoke0:34has spread over the surrounding hills.0:36The latest estimate comes from Monday afternoon, October 19th, 2026.0:40It replaces Sunday morning's smaller assessment.0:42Both the estimated acreage and containment have increased, so crews are dealing with0:46a larger incident while securing more of its perimeter.0:49The estimated footprint rose from 731 acres Sunday morning to 1,3650:55acres Monday afternoon.0:57Containment improved from 5% to 23%.1:00Those are successive assessments of the same fire, with Monday afternoon's figures1:04giving the newer picture.1:05That's an increase of 634 acres, about 87%, in the estimated fire1:10area.1:11Containment rose 18 percentage points.1:14Containment measures the perimeter secured by control lines or other barriers1:17expected to hold.1:18Crews still have substantial work ahead at 23 percent.1:22Air quality officials conditionally authorized up to 850 acres of prescribed burning1:27in Cooley Ranch's Unit 8 for October 16th.1:30That permission depended on weather and air conditions.1:33The authorization doesn't tell us how many acres were actually ignited.1:36The private burn escaped after flames crossed a road at the top of a ridge.1:40Cal Fire recorded the wildfire incident at 5.05 Friday afternoon and took over1:45suppression around that time.1:46The planned burn had its own earlier ignition.1:49Nobody has identified which authorized burn unit escaped, so the 850 acre maximum1:54can't settle whether an operating condition was violated.1:56Better mapping cut Saturday's preliminary estimate from 1,000 acres to 558.2:02The estimate reached 7.31 that evening and stayed there Sunday morning.2:06Monday's assessments then put it at 1,156 acres in the morning and2:111,365 in the afternoon.2:14Sunday's figures came from the October 18th morning update.2:17Monday morning's assessment already had containment at 23%, and that percentage held2:21in the afternoon listing.2:23The acreage history leaves part of the increase unexplained.2:25We don't know how much came from new burning and how much from better mapping.2:29Steep slopes and limited access roads have made it harder for crews to get ahead of2:33the fire.2:33Smoke also complicated suppression.2:36Overnight operations included night-flying helicopters supporting firing operations,2:40in which crews used deliberate burning as part of their effort to control the2:44wildfire.2:47Cal Fire expected increased fire activity Monday afternoon as atmospheric conditions2:52shifted.2:53That forecast added urgency to the work on the perimeter.2:56A later assessment would be needed to say how the fire actually behaved after the2:59afternoon update.3:00Smoke shrouded the hills around Lake Sonoma on October 17th.3:04By Monday, Smoke was also reaching across Sonoma County and parts of Napa County.3:08The Air District extended its wildfire smoke advisory through Monday, October 19th,3:13bringing a public health concern beyond the immediate firefighting area.3:17The earlier advisory forecast smoke moving south into portions of the North Bay,3:21including Marin and Napa counties.3:23Roenert Park also warned that drift smoke might reach the city.3:26Those warnings described possible exposure, conditions can vary between communities,3:31and a regional advisory doesn't give a measured concentration for every location.3:35Officials reported zero injuries and zero threatened structures in Monday's account.3:39People near the fire still need a current determination on evacuation restrictions3:43and road access.3:45The absence of threatened buildings doesn't tell residents whether a particular road3:48is open.3:49A Sunday particulate estimate of 68 also lacks a confirmed scale, monitoring3:55location, and observation time.3:57It can't reliably describe anyone's air quality.4:00The latest dated fire assessment remains 1,365 acres and 23% containment on4:06Monday afternoon.4:07Cal Fire is still investigating why the private prescribed burn escaped.記事を読むストーリーの時系列HeyDexショート動画 ↗誰が何を報じたか複数のメディアが報じた論点Reported size of the Cooley Fire2媒体Reported containment of the Cooley Fire2媒体How and when the
