华盛顿州海岸大风观察：周六夜阵风或超58英里，周日海浪高达28英尺
美国国家气象局西雅图办公室周五晚间更新的预报讨论指出，华盛顿州格雷斯港县海岸与北部海岸的大风观察（High Wind Watch）持续生效，时段为周六（11月7日）下午至深夜。一道强冷锋将于周六夜间自西向东扫过华盛顿州西部，带来一段稳定降雨与强劲南风。
气象局援引最新模式指出，周六较晚时段沿海阵风超过58英里/小时（大风警报门槛）的概率为50%至75%，其余多数地区周六下午至周日凌晨阵风可达30至45英里/小时，锋面过境时雨强短时可达每小时0.15至0.25英寸。由于许多树木仍带叶，局地停电可能发生；强风与降雨叠加还可能堵塞雨水口，周六晚间出行应预留额外时间。近海方面，沿海水域风暴警报（Storm Warning）周六上午10时至周日上午10时生效。
周日较稳定的降雨转为阵雨，海浪将增至20至28英尺，气象局已发布大浪提示（High Surf Advisory），周日凌晨4时至晚间10时生效，海边活动须格外小心。山区降雪高度将由周六夜的约7500英尺降至周日的约4500英尺。气象局同时表示，未来七天不预期发生河流洪水。（来源：美国国家气象局）
High Wind Watch for the Washington Coast: Gusts May Top 58 mph Saturday Night, Surf to 28 Feet Sunday
In its Friday evening forecast discussion, the National Weather Service office in Seattle said a High Wind Watch remains in place for the Grays Harbor County Coast and the Northern Washington Coast from Saturday afternoon through late Saturday night, as a potent cold front moves east across western Washington Saturday night, bringing steadier rainfall and strong southerly winds.
Latest guidance suggests a 50 to 75 percent chance of gusts exceeding 58 mph, the High Wind Warning threshold, later Saturday along the coast, with gusts of 30 to 45 mph possible for most other areas Saturday afternoon into early Sunday and rain rates briefly reaching 0.15 to 0.25 inches per hour along the front. With many trees still in full foliage, localized power outages are possible, clogged storm drains may occur as gusty winds overlap the rain Saturday evening, and travelers should allow extra time. A Storm Warning is in effect for the coastal waters from 10 a.m. Saturday to 10 a.m. Sunday.
Steadier rain transitions to showers on Sunday as seas build to 20 to 28 feet; a High Surf Advisory is in effect from 4 a.m. to 10 p.m. Sunday, and people in or near the water should use caution. Snow levels fall from around 7,500 feet Saturday night to near 4,500 feet on Sunday. River flooding is not expected over the next seven days. (Source: National Weather Service)
