Heavy satellite-observed smoke area centered at 46.165°N, 121.345°W

NOAA HMS classified a satellite-observed smoke area as heavy density, observed by GOES-EAST from 2026-10-03T20:00:00Z to 23:30:00Z. The source describes an observed smoke extent, not a ground-level air-quality measurement or health alert.

Illustrative image: This images, acquired on March 12, 2011 by NASA Terra spacecraft, shows a large smoke plume that appears to be associated either with the Shiogama incident or Sendai port fires. 3D glasses are necessary to view this image. — NASA/GSFC/LaRC/JPL, MISR Team/NASA Image and Video Library, NASA Media Usage Guidelines

Generated scores

Scores are based on the cited reporting and use a 1–10 scale. Read the methodology.

Confidence: 5/10How certain the assessment is based on the clarity and evidence in the cited reporting.
Geographic reach: 1/10How widely the event reaches, from a local area (1) to worldwide impact (10).
Global importance: 3/10The event's broader significance, from limited importance (1) to major global importance (10).
Impact magnitude: 1/10The scale or severity of the real-world impact, from minor (1) to extreme (10).
Positivity: 5/10How harmful or beneficial the event is, from strongly harmful (1) to strongly positive (10).
Urgency: 2/10How time-sensitive the event is, from low urgency (1) to immediate attention needed (10).

Why it matters

The report distinguishes satellite-observed smoke extent from ground-level air quality and health alerts.
