费尔韦瑟角至冰角近海浪高上升,风暴警报延长

对于正在决定是否离港,或是否继续穿越阿拉斯加湾暴露海域的海员来说,最新经核实的预报带来两项令人不快的变化:海浪更高,风暴警报延长三小时。警报定于周一夜间午夜结束,但这绝不意味着危险解除。预报员预计之后还将持续18小时的大风天气,浪高仍可达30–35英尺。27
美国国家气象局朱诺分局在2026年11月9日阿拉斯加标准时间凌晨5:52发布的通报预报称,费尔韦瑟角至冰角外海15至80海里海域将出现东南风,风速40–60节,阵风最高70节,浪高37–42英尺。通报将风暴警报安排至当夜午夜(即11月10日周二开始时),而非此前设定的晚上9点结束。27
这些细节来自独立存档机构Warning Vector保存的美国国家气象局警报记录。它们显示了预报和警报安排如何变化,但最新的实时警报状态尚未得到独立确认。风速和浪高数据是预报,并非表明船只已遭遇这些海况或这些浪高已经出现的实测数据。
这一区别很重要,因为警报描述的是可能造成破坏的海况,而非有记录在案的海难。美国国家气象局指出,船只可能倾覆或受损,能见度也可能降低。经审阅的记录并未证实有船只失踪、救援、人员受伤或死亡。27
浪高增加,风暴警报结束时间延后
近海预报如何变化
浪高增加2英尺是预报发生了变化,并非海面实测升高了2英尺的证据。同样,午夜这一截止时间是预定的警报结束时间,并不保证海面届时会变得安全。
地理位置与时间同样重要。这项警报覆盖海区编号PKZ671,即费尔韦瑟角与冰角之间的近海带。它并不自动适用于紧邻海岸的另一片海域。航线相对于离岸15至80海里的边界所处的位置,决定适用哪个预报海区。27
在11月9日的播报中,我们报道了冰角至萨克林角海域浪高35–40英尺、阵风最高75节,并称风暴警报安排在周一上午9点至午夜。这是另一片近海区域,海区编号PKZ672。本文所述修订针对费尔韦瑟角至冰角海域,不应被解读为邻近海区数据也作了修订。
午夜过后,海况仍然危险
最新存档通报将大风警报安排在周一夜间午夜至11月10日周二阿拉斯加标准时间下午6点。该时段预报东风风速35–45节,阵风最高60节,浪高30–35英尺。警报级别虽有变化,但预报描述的仍是严重的近海危险。27
预计风暴来临前也并非完全风平浪静。周日的展望包括一项小型船只警报,预报浪高7–8英尺;随后是周一午夜至凌晨3点的大风天气预报,预计东风风速35–45节、阵风最高55节,浪高7–12英尺。对于试图寻找通航窗口的人来说,这一先后顺序很重要:风暴时段前后都有其他海上危险。10
周一早间的记录同样区分了这两种时间:消息于周一阿拉斯加标准时间下午2点到期,而警报文本和事件结束字段将风暴安排至午夜。因此,仅凭消息到期并不能证明警报已取消。同样,这一存档记录序列也无法证实后续通报是否延长、缩短或取消了警报。27
海员应留在港内、改变航向和/或固定船只,以应对恶劣海况。
这项指示是预报中最实际的核心内容。决定是否出发、如何调整航向以及如何固定船只,都需要依据实际航线对应的最新警报,而不是较早的浪高范围、邻近海区的预报,或被误当作危险结束时间的消息到期时间。在最新经核实的存档安排中,午夜标志着从风暴警报转为大风警报,而不是海况恢复安全。

播出原貌
- Forecasters raised the sea forecast to 37–42 feet and extended the storm warning three hours.
- Severe winds and hazardous seas could capsize or damage vessels and reduce visibility. Mariners face decisions about leaving port and continuing through exposed waters. What conditions follow the storm warning's scheduled end?
- On November ninth, we reported 35-to-40-foot seas and gusts up to 75 knots for Icy Cape to Cape Suckling. That was a different offshore zone. Cape Fairweather to Icy Cape now has a 37-to-42-foot sea forecast.
- The earlier broadcast covered a storm warning scheduled from nine a.m. Monday through midnight. The changes in this update concern waters farther along the coast, between Cape Fairweather and Icy Cape.
- The forecast covers waters 15 to 80 nautical miles offshore in the Gulf of Alaska. Those boundaries matter for anyone planning a route. The separate waters immediately along the coast have their own forecast and warning area.
- Monday morning's storm forecast calls for southeast winds of 40 to 60 knots, with gusts reaching 70 knots. Forecasters kept those speeds from the previous evening, but changed the wind direction from east to southeast. They also moved the scheduled storm ending from nine p.m. to midnight Monday night.
- Forecasters expect seas of 37 to 42 feet during the storm period. That's a forecast of dangerous conditions offshore. These figures don't tell us that a vessel has already encountered those seas or that the forecast heights have already occurred.
- Sunday afternoon's forecast had called for seas of 35 to 40 feet. Sunday evening's update raised both ends of that range by two feet, to 37 to 42 feet. Monday morning's update kept the higher range. The two-foot change describes how the forecast changed, rather than a measured rise in the ocean.
- Sunday evening's message expired Monday morning, while scheduling the storm through nine p.m. Monday. Monday morning's message expires that afternoon, while scheduling the storm through midnight. Those separate message deadlines don't mean the storm warning was canceled.
- The first Sunday message even expired before the storm's scheduled three a.m. Monday start. Its warning text and encoded event times still agreed on a nine p.m. ending. Monday morning's text and event-ending fields agree on midnight. We don't know whether a later warning has changed that schedule.
- Forecasters also expected hazardous conditions before the storm period. Sunday's first outlook carried a Small Craft Advisory with seven-to-eight-foot seas. A gale period from midnight to three a.m. Monday followed, with east winds of 35 to 45 knots.
- That earlier gale forecast included gusts to 55 knots and seas of seven to twelve feet. Forecasters also expected rough conditions after the storm. Sunday's afternoon outlook scheduled another gale from nine p.m. Monday to six a.m. Tuesday, with southeast winds of 35 to 45 knots.
- Forecasters tell mariners to remain in port, alter course or secure their vessels for severe conditions. The decisions depend on a vessel's location and route through the exposed offshore waters, where the warning identifies capsizing, vessel damage and reduced visibility as dangers.
- The earlier following-gale outlook included gusts to 65 knots and seas of 32 to 37 feet. Sunday evening, forecasters increased its winds to 40 to 50 knots and seas to 33 to 38 feet. Gusts stayed at 65 knots. Monday morning then changed both that gale's timing and its forecast.
- The storm warning is scheduled through midnight Monday night, the start of Tuesday, November tenth. The following gale warning runs from midnight to six p.m. Tuesday. That leaves another eighteen hours of hazardous wind and sea forecasts after the storm period.
- For that following gale, forecasters expect east winds of 35 to 45 knots and gusts up to 60 knots. Mariners still need the latest warning before making decisions offshore. Even after the scheduled storm ending, seas remain forecast at 30 to 35 feet through the gale period.
