Smoke

Mostly MODERATE AQ is expected west of Canyon Ferry Lake toward Helena. Moderate to periods of USG remains possible more likely east and southeast of Canyon Ferry Lake and into the higher wilderness eastward and immediately downstream of the fire. After dusk, smoke from the Horse Gulch Fire will settle into local drainages including S-284, Canyon Ferry Lake and perhaps Hwy 12 toward East Helena. A large number of monitors over southern Montana are indicating MODERATE AQ due to ongoing regional fires in surrounding states.

Roadway Visibility

Localized smoke conditions can bring reduced visibility along S-284 to the Canyon Ferry Lake south of the fire overnight and in the early morning. Visibilities should remain at least one mile or greater however along S-284.
