灾害 · 昆西计划烧除作业四角区142英亩区域点火后，昆西烟雾风险仍存文字 2026年10月30日 UTC 19:41观看文字实录0:07Flames from the prescribed burn were visible from Quincy.0:10Firefighters ignited about one hundred and forty two acres, and remaining fuels are0:14still burning.0:14Smoke could reduce visibility on nearby highways even as crews pause new ignitions.0:19What does that pause mean for smoke and travel around Quincy?0:22Firefighters moved east from South Park to Four Corners, north of Quincy.0:25The burn unit sits north of Mount Hoff Road, south and east of the Teardrop Trail0:29and west of the Fireline Trail and Four Corners.0:31The Mount Hoff Ranger District is doing this work as part of the North Quincy0:35Project in Plumis National Forest.0:36Crews are reducing vegetation that can fuel wildfire near communities.0:40The Forest Service also intends the burning to help restore forest health.0:43At Four Corners, it said burning conditions were excellent and fuel consumption met0:47the intended effects.0:48Firefighters completed ignitions on about one hundred and forty two acres Thursday,0:52October twenty nine, matching the planned acreage.0:55Crews were still securing the area that night.0:57Fuels continued burning, with an overnight glow expected and more smoke possible1:01into Friday.1:02The operation combines pile burning with underburning.1:04Pile burning consumes vegetation gathered into piles.1:07Underburning consumes needles, leaves, branches, and low vegetation beneath the tree1:11canopy.1:11Local firefighters receive support from Calphires Lassen, Modoc Unit, Feather River1:16Resource Conservation District, Forest Corps, Mendocino National Forest, Angeles1:20National Forest, and Fulton Hotshots.1:21South Park's larger plan covered about four hundred and four acres between Chandler1:25and Oakland camp roads, beside residences and private timberlands.1:29Crews aimed to treat about one hundred and fifty two acres Wednesday, October1:33twenty-eight, beginning near the ridge and bear cub trails and working west.1:36Test fires succeeded around eleven that morning, and crews continued lighting fires,1:40but the promising start didn't last.1:42Firefighters found that good fuel consumption and fire effects couldn't be sustained1:46across enough ground.1:47The operating window was too short to make the progress they needed, so they halted1:51further ignitions.1:52The earlier South Park update put the area ignited at about three acres.1:55The later figure was about one point two acres successfully treated.1:59Officials haven't explained whether the difference reflects a revised estimate or a2:02different way of counting the work.2:04Those figures can't be added together or treated as a confirmed correction.2:08Crews fully lined and secured the treated area while fuels burned down.2:11South Park's trail system reopened, including access previously affected by closures2:15at South Park, also called Barlow, and monument trailheads.2:19Trail users could still encounter smoke.2:21Crews planned continued monitoring and further burning when conditions improve.2:25Fuels can keep burning after firefighters stop lighting new fires.2:28At four corners, flames were potentially visible from Quincy again Friday during2:31daylight.2:32Crews were to keep monitoring conditions and stop burning if weather turned2:35unfavorable, including increased or gusty winds.2:42The initial smoke forecast reached Quincy, Keddy, Butterfly Valley, Taylorsville,2:47Gensey, Indian Valley, Meadow Valley, and Greenhorn Ranch.2:50It also covered Mount Huff, Chandler and Oakland Camp Roads, and Highway70 .2:54Smoke could settle in lower areas around Chandler Road, Quincy, Keddy, and Feather2:58River Canyon communities, with limited impacts possible in Indian Valley.3:02Smoke spread widely Thursday and settled that night in East Quincy, Quincy,3:06Greenhorn Ranch, Indian Valley, and the Feather River Canyon.3:09Smoke-sensitive people in those areas were advised to monitor conditions and take3:13precautions as needed.3:14Settled smoke was expected to clear Friday morning, while fuels continued producing3:18more smoke Friday.3:20Reduced visibility was possible overnight and early Friday on highways seventy and3:24eighty, nine Chandler Road, Mount Hoff Road, and other local roads.3:27The Forest Service didn't expect long term smoke impacts, but nearby residents and3:31travelers could still be affected during the burn down.3:33The earlier schedule allowed more South Park burning as early as Sunday, November1.3:38By Thursday night, crews had no new ignitions planned for Friday or through the3:42weekend.3:42Their immediate work was securing and monitoring the four corners burn.3:45No road or trail closures were reported at four corners, but nearby trails could be3:49smoky.3:50Firefighter traffic increased on Mount Huff and Chandler Roads.3:53Travelers were asked to avoid Mount Hoff Road if possible and use alternate routes.3:57On Highway70 near the Ranger Station and Chandler Road, firefighting equipment4:01entering and leaving roadways could slow traffic.阅读文章事件时间线HeyDex
