Smoke In Yosemite
Over the past few days, Yosemite has been experiencing some high smoke concentrations.   The recent weather pattern of higher temperatures and stable air has created conditions that have allowed the Empire fire to burn into an area with heavier fuels that produced smoke that didn’t fully clear out in the afternoons.   Smoke from other fires in the state, particularly those north of the bay area, has also contributed to the poor air quality in the park. While there may be some relief over the next couple days, this pattern is forecasted to return again this weekend and into next week. Air quality in Yosemite Valley and El Portal may go into the Air Quality Index category of “Unhealthy” at certain times over this period.

Prescribed Fire Update

On Saturday Yosemite Fire managers made the decision to postpone the prescription burns in the Mariposa Grove and the Soupbowl until further notice.  A dry stable air mass with low relative humidity was the primary driver for being out of prescription.


Prescribed fire is a very important tool for reducing excessive fuel build up near our communities in order to reduce severity of future fires.  When the conditions are right, we hope to proceed with these prescribed fires. 

WTREX (Women in Fire Prescribed Fire Training Exchange) will continue working with Yosemite Fire crews.  You might see a high percentage of women firefighters from various federal, state and other non-profit agencies assisting the park with fire management activities.  Currently only 10% of wildland fire positions are filled by women. This international 12 day training is comprised of 90% women.  
There are multiple fires burning in Yosemite National Park's wilderness. Fire managers are working with the local Air Quality Pollution Districts and will be monitoring smoke impacts to the park and local communities. Due to moderate smoke production from the Empire wildfire, Yosemite Valley will experience smoke, this will be compounded with campfire smoke until the morning inversion lifts.

Yosemite Valley Parking and Road Construction Update

Contractors will continue work on Northside Drive between Sentinel Drive and the Yosemite Lodge crossing near Yosemite Falls. Currently they are installing curbs. Flaggers will control traffic, with one lane open at a time.


Contractors will also continue roadwork on Northside Drive from the Yosemite Lodge intersection to just past Camp 4. The Camp 4 parking area will remain closed while contractors set wheel stops. Campers will continue to have parking available across the street at the Yosemite Falls parking area. Northside Drive between the Yosemite Falls crossing and Camp 4 will remain limited to one westbound lane. Eastbound traffic will continue to travel through Yosemite Lodge. The contractors hope to complete this work by Thanksgiving if the weather remains favorable.


Masons will begin work on the masonry headwalls on Northside Drive in the west end of Yosemite Valley and El Portal Road between Pohono Bridge and the Big Oak Flat intersection. Work will take place during the day, with one lane closed near each headwall.  (L. Acree)
