Smoke from distant wildfires is drifting into the park, causing poor air quality in northern and western areas. Conditions are expected to remain hazy through tomorrow.

The smoke is coming from distant wildland fires and is being pushed into the region by wind. If you are planning to head north from Jackson, you can check the AirNow interactive map to see real-time conditions. Heat and drought across the western U.S. mean these conditions could persist, so it is best to check the air quality before spending extended time outside.
