This Hazard Mapping Smoke and Fire Product image procured from GEOS-East and GOES-West satellite data shows heavy amounts of smoke in the Washington, Montana and Oregon regions (Figure 1). According to INCIWEB, the Williams Flat Fire west of Spokane is still active with movement to the east/northeast. It’s significant impact on the environment can be seen in the hazard map as the smoke stretches horizontally from east Washington. Colville Tribes Emergency Services and the Ferry County Sheriff’s Office have both issued Level 3 Evacuation Notification to residents. This urges residents to “Leave Now”. It is reported on INCIWEB that although homes are not in immediate danger, the main concern is that the fire will grow and block the only exit to the area. The effects of the Devore Creek Fire can also be seen in Washington northwest of the Williams Flat Fire. The HK Complex Fire is causing significant smoke levels in north-central Oregon. Smoke from the Granite Gulch Fire can also be seen in Oregon’s northeast corner. Details about these fires are readily found on INCIWEB.
A more general view of the satellite data shows heavy smoke over British Columbia caused by fires near the area. Light to moderate smoke is also seen in various spots across Canada and Alaska (Figure 2).
Figure 3 and 4 below are satellite images from GOES-EAST itself. Figure 3 is time stamped at 1431 UTC, while Figure 4 is time stamped at 1651 UTC. Observe how the smoke from the William’s Flat Fire is spreading eastward over time. The smoke is grayer than the white clouds and is inside the red circle. Most noticeable is the movement of the smoke just east of Spokane.
Figure 5 below is an image from the VIIRS (NOAA-20) satellite which shows the smoke stretching from Alaska through British Columbia. Once again the smoke is grayer than the white clouds and is inside the red circle.
