Expect hazy conditions with smoke lingering in the river drainages much of the day. Air quality should improve in the afternoons, with Good to Moderate AQI likely in the foothill communities. El Portal, Foresta, and Yosemite Valley will see higher concentrations due to their proximity to the fires. With the unsettled weather, there is potential for rain showers and gusty winds and air quality conditions could change quickly.

Widespread smoke/haze can be expected over the region due to local fires and other fires across the state which will result in primarily Moderate AQI for all locations. Periods of increased smoke can be expected during the morning through midday, especially within the Tuolumne Rivers, Merced River, Chilnuana Creek, and other nearby drainages, as a result of the Red and Rodgers Fires smoke settling into the valleys during the overnight. Up to Unhealthy AQI can be expected for many park locations with up to Very Unhealthy AQI within the Yosemite Valley each day.

With an unsettled forecast this weekend there is potential for rain showers and gusty winds. There will be potential for quick changes in weather and air quality conditions with rain showers helping clear the air, and gusty winds pushing smoke in any direction.

Smoke from multiple California wildfires is impacting air quality this morning throughout the region with at least Moderate to Unhealthy for Sensitive Groups (USG) Air Quality Index (AQI) for all locations. Conditions will improve by early afternoon for most with Good to Moderate AQI for the late afternoon. Smoke will once again settle this evening and overnight with air quality impacts expected for Saturday morning.

The potential for cloud cover throughout the weekend may cause smoke to linger later into the daytime before improving. However, the potential for rain showers and outflow winds may create cleaner air for some while pushing smoke to others. Overall, continue to expect the largest air quality impacts during the morning hours with at least some improvement for the afternoons.

Smoke from the Red, Aspen and Rodgers Fires will impact air quality throughout the Merced River drainage from Yosemite Valley westward to Lake McClure as well as areas of southern Yosemite NP southwest towards the central valley. Largest smoke impacts will be in within the park with short-term AQI reaching Unhealthy for most locations, and even Very Unhealthy to Hazardous for Yosemite Village. Smoke from the Rodgers and Aspen Fires will settle into the Tuolumne River and nearby valleys with Moderate-USG AQI at times from Tuolumne Meadows to Hetch Hetchy Reservoir, Hodgdon Meadows, and to Groveland and nearby areas, primarily during the morning. Light smoke will also impact Lee Vining and Mammoth Lakes at times. Smoke from Yosemite NP fires and other fires in California will also contribute to smoke impacts along the foothills, including the Mariposa area.

Forest Closure Update - On Sept. 15, Four Corners Fire Closure Order was issued and was reduced in size. See Closure Order #0402-04-95 below.  Public can now access Snowbank Mtn. (FR 446) and travel through Anderson Creek (FR 435). Through traffic only on Anderson Creek Rd. Be aware of firefighter traffic and heavy equipment working in the area.

Yesterday evening the closure area of the fire was reduced in size (see Maps tab).  Recreationists can now enjoy Snowbank Mountain and the areas surrounding the fire.  Travel on the Anderson Creek 435 road will be allowed but fire officials ask that you drive slowly and watch out for fire traffic who are still patrolling and working in the area. 

Today crews will continue to focus on mopping up further into the fire from the containment lines. Even though the moisture in the area has increased lately the rainfall is not putting out the fire.  Firefighters still need to hike into the fire and mix the wet soil with the smoldering duff edges and the large dead logs on the ground need to be cut up and broken apart to get moisture on them to be extinguished.  Aircraft support will be available from the McCall airport if crews need water dropped in areas where there are no streams.

Repair work continues in areas where the fire is out cold.  Excavators and hand crews are pulling back dirt berms to create a smooth, contoured surface and then brush and slash is spread back over the line.  The slash will help protect the soil from erosion.

Smoke will continue to be visible within the fire perimeter. Do not call 911. Instead, report fire activity or smoke within the fire perimeter by calling 208-510-8412. Firefighters will continue to monitor the fire area by air and ground and will respond to any fire activity as necessary.

Weather:  On Friday there is a 30% chance of rain showers and chance of thunderstorms in the afternoon. Temperatures will remain cool with highs expected to be in the low 60s.  Cooler temperatures will remain through the weekend, along with higher humidity.

Fire Restrictions: There are currently no fire restrictions in the area. Residents and visitors are encouraged to exercise extreme caution if building campfires. Local fire restriction information can be found at: https://tinyurl.com/vptsh85r.

Air Quality:  Specific information about local smoke levels, forecasts, and possible health impacts is available at https://outlooks.airfire.org/outlook/cc0ac676/.

Evacuation Information: Valley County Sheriff's Office announced the termination of evacuation status (ready-set-go) Please visit www.wildlandfirersg.org for evacuation level information.

Closure Information: The new closure includes an area around Collier Peak and the fire perimeter. Complete closure order for the Boise and Payette National Forests – including a full description and an accompanying map – is available at https://InciWeb.nwcg.gov/incident/closures/8331/.
