UPDATE: A powerful snowstorm is poised to strike Mammoth Mountain just as the resort gears up for its highly anticipated opening day on Friday, November 14, 2025. This significant weather event will bring vital snowfall to the Eastern Sierras, potentially delivering between 1 and 2 feet of snow at elevations over 9,000 feet.
The Mammoth Mountain Ski Area, located in the Sierra Nevada Mountains and roughly a five to six-hour drive from Los Angeles, is set to kick off its 72nd season. A strong Pacific low-pressure system is expected to arrive late this week, bringing much-needed precipitation to the area. Meteorologists from the National Weather Service predict a “decently robust” snowfall, with a 90% chance for the upper mountain to receive at least 1 foot of snow.
Chris Johnston, a meteorologist, stated, “It looks pretty good.” The storm is anticipated to begin impacting the region on Wednesday, November 12, with strong winds accompanying the snowfall on Thursday, November 13. Fluffy snow is expected to start accumulating that night.
This timely weather change is crucial for Mammoth Mountain, which attracts over 1.3 million skiers and snowboarders each year, primarily from Southern California. Last year, the mountain recorded only 286 inches of snow for the entire season, falling short of the average. This year, however, Mammoth has already accumulated 16 inches in October alone.
Joani Lynch, vice president of marketing and sales for Mammoth Mountain, expressed hope that the National Weather Service’s forecast will hold, emphasizing that the resort’s opening day will hinge on the storm’s timing. “If we can’t make it Friday, we will aim for the first day there is enough snow on the ground,” she said. The resort requires a base of 12 to 18 inches for safe operation, which will be enhanced by manmade snow as temperatures drop.
On opening day, all chairlifts and runs will operate from the Main Lodge, with plans to expand operations as quickly as conditions allow.
Across Southern California, forecasters predict rain, with the San Bernardino Mountains set to receive their first snow accumulations. In the San Gabriel Mountains, snow showers are likely on Thursday and Friday, although totals are expected to remain under an inch in places like Mount Baldy.
As Mammoth Mountain prepares for what could be a record-setting season, winter sports enthusiasts are eagerly watching the forecast. With the potential for substantial snowfall, this season opener is shaping up to be one of the most exciting yet. Stay tuned for updates as the storm approaches!
