Fire Update September 14th
 
There are multiple fires burning in Yosemite National Park's wilderness. There has not been any change in size on the fires. Glacier Point Road is still closed due to fire operations along the road. Showers and thunderstorms are possible through this evening with increased relative humidities and cooler temperatures through the weekend. Gusty and erratic winds are possible with any thunderstorm that develops. 

For the Most up-to-date fire information : https://www.nps.gov/yose/blogs/fireinfo.htm

Overall, monitors are in the good/moderate range in the Yosemite area. Yosemite West and Wawona had only brief local smoke from the Empire/South Fork Fires overnight. Morning smoke from the Empire Smoke has also been visible in the western end Yosemite Valley (e.g., from Tunnel View), but disperses by afternoon and has little effect on the eastern end of Yosemite Valley (i.e., Yosemite Village). Dispersion will likely improve today and tomorrow, with strengthening SW winds in the afternoon, and decreasing chance of thunderstorms.

Yosemite Forum Monday, September 18 (Note Special Date)
"A snow hydrologist's apology: Demystifying Sierra snow and ice with the NASA Airborne Snow Observatory" by Dr. Thomas Painter, NASA
 
The NASA Airborne Snow Observatory (ASO) has revolutionized how we characterize Sierra Nevada snowpack and mountain glaciers, in a way sadly laying waste to our mythical understandings of this most critical resource and landscape. Prior to the ASO, we largely understood snowpack and glacier dynamics from what we could see or measure on skis or foot, with the federal sampler, a depth probe, a GPS unit, a tape measure, wood stakes, a stone, horse-hair, and a load of Scottish chutzpah. Now, putting assumptions behind us that have led to unverifiable myths, the ASO allows us to finally quantify Yosemite’s snow water equivalent, snow reflectivity, snow grain size, dust and black carbon enhancement of sunlight absorption, glacier volume changes, snow algae concentrations, periglacial forms, ecosystem function, and controls on snow versus glacier melt contributions to runoff. My sincerest apologies … look away if you want to keep the mystery!
 
The Forum will take place Monday, September 18, from 3:30 to 4:30 pm in the Yosemite Valley Auditorium.  Please contact Greg Stock at 379-1420 for additional information.  (G. Stock)

CONSTRUCTION & TRAFFIC DELAYS
 
Glacier Point Road Closure - Empire Fire
The Glacier Point Road will remain closed to the public this week as fire crews conduct backfiring operations along the roadway between Ostrander Lake and Mono Meadow Trailheads. Depending on how these operations go, crews will re-assess conditions on Friday and make further determinations on the road closure at that time. The road is still open to Admin Traffic Only.  (E.

Yosemite Valley Parking and Road Construction Update
A new phase of parking and road construction in Yosemite Valley will be starting on Monday, September 18th. The biggest project will be reconstruction of the Camp 4 parking area. The parking area will close on Monday, September 18th and campers will park across the street at the Yosemite Falls parking area. Northside Drive between the Yosemite Falls crossing and Camp 4 will narrow to one westbound lane. Eastbound traffic will travel through Yosemite Lodge. The contractors hope to complete this work by Thanksgiving if the weather is good. If not, the parking area and roads will be open for the holidays.
 
In addition, new construction will begin on Tuesday, September 19th at the four-way intersection at Half Dome Village near Stoneman Bridge. Flaggers will route traffic headed to Half Dome Village in a one-way clockwise loop going eastbound on the Happy Isle Loop Rd then coming back northbound on Curry Village Dr. This work should take about two weeks.
 
Work on Northside Drive east of Pohono Bridge is almost complete. Contractors will work on utility vaults in Northside Drive for one week starting Monday, September 18th. This work will take place during the day with one lane open. There will be maximum 30-minute delays.
 
Lastly, night work will continue at “the Narrows” through September (same schedule as earlier in the month) and work on the pedestrian pathway from the Yosemite Village parking area to Yosemite Village will continue through Monday, September 18th. Thank you for your patience.  (L. Acree)
