太平洋风暴夜袭爱达荷州东部，蛇河平原阵风可达40英里
爱达荷州东部10月25日迎来天气转折预报：一股快速移动的太平洋风暴将于26日夜间过境，给当地带来阵风与降雨，结束此前干燥多雾的天气。
预报显示，25日夜间局部地区仍有雾，能见度不高，夜间低温在33华氏度左右；26日上午雾气散去后气温回升，白天最高气温接近60华氏度。到了26日夜间，降雨概率达到80%，大部分雨水预计在午夜前落下，低海拔地区雨量不到0.10英寸，山区可达0.20至0.30英寸液态降水。
风是这场风暴最值得注意的部分：蛇河平原的阵风可达每小时30至40英里，驾车经过开阔地带与高架路段的司机需要格外留意横风。山区方面，降雪线将于26日深夜降至约6500英尺，山口与高海拔地区可能出现1至3英寸降雪，州际15号公路与怀俄明州边界一带的高地出现0.25英寸以上液态降水的概率超过65%。由于谷地气温偏暖，低海拔地区出现雨夹雪也不会积存。阵雨将在高地持续到本周中段。当地居民应提前收好户外物品，关注最新预报后再安排夜间出行。

Pacific Storm to Sweep Eastern Idaho Overnight; Snake River Plain Gusts Could Reach 40 mph
Eastern Idaho saw a weather turning point in the forecast on October 25: a fast-moving Pacific storm is set to cross the region on the night of the 26th, bringing gusts and rain and ending the recent dry, foggy pattern.
Fog is expected in places on the night of the 25th with poor visibility and overnight lows around 33 degrees Fahrenheit. Fog lifts on the morning of the 26th and temperatures recover, with daytime highs near 60. By the night of the 26th, the chance of rain reaches 80%, with most of it falling before midnight — less than 0.10 inch at lower elevations and 0.20 to 0.30 inch of liquid precipitation in the mountains.
Wind is the storm's most notable feature: gusts on the Snake River Plain could reach 30 to 40 mph, and drivers crossing open ground and elevated roadways should watch for crosswinds. In the mountains, the snow line drops to about 6,500 feet late on the 26th, with 1 to 3 inches of snow possible at passes and higher elevations, and high ground along Interstate 15 and the Wyoming border has a better-than-65% chance of at least 0.25 inch of liquid precipitation. With warm valley temperatures, any rain-snow mix at lower elevations will not accumulate. Showers will linger in the high country through midweek. Residents should secure outdoor items and check the latest forecast before traveling at night.
