蒙大拿的雪块在2026年是正常的, 尽管山谷下低雪, Montana’s snowpack is normal to above-normal for 2026 despite low snow in valleys, thanks to heavy high-elevation snowfall.

蒙大拿的雪块在2026年正常到超常供水, 尽管低海拔河谷的积雪低于平均水平, NRCS表示, Montana’s snowpack is on track for normal to above-normal water supply in 2026 despite below-average snow in low-elevation valleys, according to the NRCS. 高海拔地区,特别是北部和西部地区的重大降雪使密苏里、黄石公园和克拉克福克等主要河流流域的积雪量保持在强劲水平。 Heavy snowfall in high-elevation areas, particularly in the northern and western regions, has maintained strong snowpack levels in key river basins like the Missouri, Yellowstone, and Clark Fork. 虽然由于气温变暖和低海拔降雪减少,总积雪面积是25年来最低的,约为平均积雪量的60%,但高海拔积雪支持了稳定的径流预测。 Although total snow cover is the lowest in 25 years—around 60% of average—due to warmer temperatures and reduced snowfall at lower elevations, high-altitude accumulation supports stable runoff projections. 部分州持续存在干旱状况,但今年春季和夏季供水的总体前景仍然乐观。 Drought conditions persist in parts of the state, but the overall outlook remains positive for water availability this spring and summer.
