Snow is falling in the Sierra Nevada on the last day of summer, bringing a wintry look to the towering range shared by California and Nevada.

Forecasters said Thursday the September snow is early but not unheard of, and is being caused by a cool weather system moving south from Oregon.

National Weather Service forecaster Hanna Chandler says several inches (centimeters) of snow are expected at elevations of at least 6,000 feet (1,830 meters) in the northern Sierra.

Tioga Pass, the soaring eastern entry to Yosemite National Park, has been temporarily closed due to snow and a park webcam shows the white stuff covering the landmark Half Dome.

Southern California is also taking an early leap into fall, with cloudy skies and rain showers across the region.

Autumn begins at 1:02 p.m. PDT Friday.
