The last 24 hours
The GIS perimeter reads 172,705 acres, still 81% contained (perimeter dated Sep 15, 8:47 AM PDT, about 7.5 hours old at capture) — flat against this morning's run, no change in acreage, containment, or nearest edge. InciWeb's page for the fire carries the same 172,705 acres, 81% containment, and 697 personnel, and describes up to an inch of rain substantially reducing fire activity — "scattered areas of smoldering with limited creeping in duff and exposed surface fuels" — with heavy fuels still able to hold heat and reignite during drying periods. It also notes international firefighting crews recently assisted before departing, consistent with the fire's shift from active spreading into a containment and mop-up phase.
No zone anywhere on the perimeter has been edited since Sep 3. The Level 1 ring closest to the house holds at 2.0 mi NNE (unedited since Sep 1), and the nearest Level 3 ring is unchanged at 5.1 mi N. Nothing here trips the tracker's alert condition.
VIIRS logged zero detections region-wide in the last 24 hours — the sixth consecutive zero read. All five near-Plain clusters are unchanged in distance, detection count, and distinct-day count from this morning — no new detections in any of them — and all remain classified persistent, sitting inside the fire's existing mapped footprint: 6.1 mi NE (7 over 3 days), 6.7 mi NE (20 over 4 days), 8.5 mi NNE (3 over 2 days), 8.9 mi NNE (9 over 3 days), and 10.1 mi NNE (8 over 2 days). A full news sweep (InciWeb above; lakewenatcheeinfo.com — unreachable again, empty response; Lake Chelan Now, still showing only its Sep 12 RAWS weather-station piece, nothing on geometry; the Chelan County active- emergencies page — still dated Aug 17, well past the 10-day staleness threshold for boundary claims, so discarded; wasmoke.blogspot.com, still showing the Sep 11 post on satellite hot spots and moderate-to-unhealthy smoke in Cle Elum, Chelan, and Leavenworth — now four days old, nothing newer posted; and a general search, which surfaced only older Wenatchee World and Lake Chelan Mirror/Cashmere Valley Record articles from earlier growth stages — 70,000, 132,978, and 171,302 acres — all discarded as stale) found nothing new beyond InciWeb's operations detail above.
Fire weather
This afternoon has been calm and cool with a 40% chance of light rain, essentially no sustained wind, under a high near 62. Tonight turns northwest, around 1 mph — the favorable quadrant, pushing the fire southeast and away from Plain — mostly clear, low 45 rising to 47 overnight. Wednesday shifts to southwest, around 2 mph, sunny, high 74; Wednesday night moves to northeast, around 2 mph — technically the drainage-danger direction, but at this speed it isn't a push worth watching — mostly clear, low 46. No sustained north/northeast wind appears in this forecast window, and no fire-weather (red flag) alert is in effect.
Air quality
Modeled AQI at the house is 50 (PM2.5 14.1 µg/m³) — still Good, up from this morning's 40 but within the normal day-to-day range for a calm, overcast day with light rain.
