The Dome Fire in Yosemite National Park has grown to 5,215 acres as of the morning of September 28th, according to the National Park Service. The fire has expanded by 406 acres since Sunday morning and is now 30% contained.
There are currently 808 personnel assigned to the incident. Fire growth has primarily occurred toward the north and northeast at a moderated pace, while crews continue working to strengthen containment lines around the fire.
Hoselines have been installed along handlines on the northern and northeastern sides of the fire. Firefighters are also improving and widening containment lines near Bridalveil Creek, Empire Meadows and Horse Ridge.
Cooler temperatures and higher humidity are expected to help firefighters through Tuesday. No roads, buildings or utilities are currently under immediate threat.
Yosemite Closures Remain in Place
Yosemite National Park remains open and is operating normally, although several areas remain closed because of the Dome Fire and firefighting operations.
Glacier Point Road is closed because of reduced visibility from smoke and to provide room for firefighting operations. The Four Mile Trail and Panorama Trail remain open to hikers seeking access to Glacier Point. The road is expected to reopen when conditions allow.
The Chilnualna Falls Trail and trails extending from the top of Chilnualna Falls toward Buena Vista and Crescent Lakes are also closed. The Ostrander Lake Trail and all areas and trails south of it remain closed.
The closure area extends east of Wawona Road between Wawona and Chinquapin.
Smoke Conditions Vary Across Yosemite
Weather conditions are expected to produce less smoke today as cooler temperatures and increased humidity moderate fire behavior.
The National Park Service expects good air quality in Tuolumne Meadows, El Portal, Hodgdon Meadow and Mariposa. Wawona could see more smoke later today as winds shift, with moderate air quality expected overall and periods of unhealthy air for sensitive groups during the evening and overnight.
Yosemite is expected to experience moderate air quality overall.
The Mariposa-Yosemite Airport also remains closed to general aviation traffic, with civilian aircraft prohibited from taking off or landing at the airport.
