South Fork Fire News Release

Smoke and Air Quality from Fires in the Yosemite Area – August 2017

Incident: South Fork Fire Wildfire
Released: 8/18/2017

Due to smoke from the South Fork Fire east of Wawona in Yosemite National Park, visitors and residents may experience some health effects while in the area.

An Air Resource Advisor, working with the Incident Management Team, the Park staff, and local Air Pollution and Health Departments, issues a daily Smoke and Air Quality Outlook. The Outlook includes a summary of smoke and fire activity and a forecast of the expected air quality relative to fine particulate matter (PM2.5) and when smoke conditions will be better or worse during the forecast period to help residents and visitors make necessary health-based decisions.

The forecasts follow EPA’s 24-hour Air Quality Index (AQI) color-coded categories for ease of connecting the situation directly to health effects. Exposure to shorter durations of high levels of smoke can also have effects on healthy as well as sensitive people. Sensitive groups include people with respiratory and circulatory disorders (asthma, emphysema, COPD for example), as well as people with smaller lung capacities – young children and babies as well as the elderly.

Here is a short list of actions which can be taken to reduce or avoid impacts.

These are only SOME of the options available to us. Please refer to, the fact sheet issued by the Yosemite Safety Office on Wildfire Smoke and Public Health and statements issued by the Mariposa County Health Department,
