Horse Gulch Fire
Publication Type: News - 07/17/2024 - 08:00
Fire
The Horse Gulch fire showed some growth on the northeast side Tuesday afternoon due to a combination of natural and selected tactical firing. Scattered burning and smoldering within the interior has produced additional smoke as well.
Smoke
With light winds and a developed inversion, Unhealthy for Sensitive Groups (USG) with periods of UNHEALTHY is forecast along the north side of Canyon Ferry Lake through at least midday. Elsewhere MODERATE to USG air quality is forecast from around Helena to East Helena and the southern portion of Canyon Ferry Lake into mid-afternoon. After dusk, smoke will settle into local drainages once again. MODERATE AQ continues across south Montana due to ongoing regional fires.
Roadway Visibility
Increased smoke will bring reduced visibility along S-284 to the Canyon Ferry Lake south of the fire overnight and in the early morning. Visibilities of one half to one mile are possible along S-284 and Canyon Ferry Road north portion of the Canyon Ferry Lake up to York through late morning.
