Portland, Oregon – Snow has shaped the winter season across Oregon, with extraordinary totals accumulating in the Cascade Mountains from late September through early February. While valleys and coastal areas have seen limited snowfall, the high terrain has experienced near-constant snow, driving major travel impacts and supporting a deep mountain snowpack.
According to the National Weather Service and regional snow monitoring data, parts of the Oregon Cascades have recorded up to 30 feet of snow since Sept. 30. The highest seasonal totals are concentrated along the west slopes and at major mountain passes, where repeated Pacific storm systems have delivered frequent, heavy snowfall.
Mount Hood stands near the top of the range, with nearby ski areas and upper elevations logging some of the deepest snowpack in the Pacific Northwest. Santiam Pass, Willamette Pass, and Government Camp have also seen relentless accumulation, leading to repeated chain requirements and temporary closures along U.S. 26, U.S. 20, and Highway 58.
Farther south, areas near Diamond Lake and Crater Lake National Park have piled up several additional feet, while eastern foothill communities such as Bend and La Pine have seen lighter but still impactful snowfall compared to western valleys.
ODOT continues to urge drivers to prepare for rapidly changing mountain conditions, noting that snowfall rates can intensify with little warning. With winter still underway, additional Pacific storms could continue to add to already impressive Cascade snow totals, and more travel advisories may be issued as conditions evolve.
