Higher seas, longer storm warning off Cape Fairweather to Icy Cape

The latest verified archived forecast raises offshore seas to 37–42 feet and schedules the storm through midnight Monday night. An eighteen-hour gale follows—not an all-clear.

For mariners deciding whether to leave port or continue through exposed Gulf of Alaska waters, the latest verified forecast brings two unwelcome changes: higher seas and three more hours under a storm warning. And the warning’s scheduled end at midnight Monday night is no all-clear. Forecasters expect another eighteen hours of gale conditions afterward, with seas still reaching 30–35 feet.⁠27

The National Weather Service Juneau’s November 9, 2026, 5:52 a.m. Alaska Standard Time bulletin forecasts southeast winds of 40–60 knots, gusts up to 70 knots and seas of 37–42 feet for Cape Fairweather to Icy Cape, from 15 to 80 nautical miles offshore. It schedules the Storm Warning through midnight that night—the start of Tuesday, November 10—rather than the previous 9 p.m. ending.⁠27

Those details come from NWS alert records preserved by the independent archive Warning Vector. They establish how the forecast and warning schedule changed, but the latest live warning status has not been independently confirmed. The wind and sea figures are forecasts, not measurements showing that a vessel has encountered those conditions or that those sea heights have already occurred.

The distinction matters because the warning describes potentially destructive conditions, not a documented maritime casualty. NWS identifies vessel capsizing or damage and reduced visibility as dangers. The records reviewed do not establish a vessel loss, rescue, injury or death.⁠27

Higher seas, then a later ending

The worsening outlook developed in two steps. Sunday evening’s update raised both ends of the storm sea forecast by two feet, from 35–40 feet to 37–42 feet, while retaining the earlier wind speeds and storm schedule. Monday morning’s bulletin kept that higher sea range but pushed the scheduled storm ending back three hours and changed the forecast wind direction from east to southeast.⁠10⁠3⁠27

How the offshore forecast changed

  1. Sunday, November 8, 3:27 p.m. AKST

    NWS forecasts east winds of 40–60 knots, gusts to 70 knots and seas of 35–40 feet. The Storm Warning is scheduled for 3 a.m.–9 p.m. Monday.

  2. Sunday, November 8, 8:32 p.m. AKST

    Storm seas are raised to 37–42 feet. Wind speeds, gusts and the scheduled storm period remain unchanged.

    3
  3. Monday, November 9, 5:52 a.m. AKST

    The bulletin schedules the storm through midnight Monday night, retaining 37–42-foot seas and forecasting southeast winds. A gale is scheduled to follow through 6 p.m. Tuesday.

The two-foot increase is a change in the forecast, not evidence of a measured two-foot rise in the ocean. Likewise, the midnight deadline is a scheduled warning end, not a promise that the sea will become safe at that hour.

Geography is just as important as timing. This warning covers marine zone PKZ671, the offshore belt between Cape Fairweather and Icy Cape. It does not automatically describe the separate waters immediately along the coast. A route’s position relative to that 15-to-80-nautical-mile boundary determines which forecast area applies.⁠27

In our November 9 broadcast, we reported 35–40-foot seas and gusts up to 75 knots for Icy Cape to Cape Suckling, with a storm warning scheduled from 9 a.m. Monday through midnight. That was a different offshore zone, PKZ672. The revisions described here concern Cape Fairweather to Icy Cape; they should not be read as revisions to the neighboring zone’s figures.

Midnight still leads into hazardous water

The latest archived bulletin schedules a Gale Warning from midnight Monday night until 6 p.m. AKST Tuesday, November 10. For that period, it forecasts east winds of 35–45 knots, gusts up to 60 knots and seas of 30–35 feet. The warning category changes, but the forecast still describes a substantial offshore hazard.⁠27

That following gale has also been revised. Sunday afternoon’s outlook placed it from 9 p.m. Monday to 6 a.m. Tuesday, with southeast winds of 35–45 knots, gusts to 65 knots and seas of 32–37 feet. Sunday evening raised its forecast winds to 40–50 knots and seas to 33–38 feet. Monday morning then changed both the timing and the expected conditions. Those earlier gale figures are superseded forecasts, not the latest outlook.⁠10⁠3⁠27

Nor was the storm expected to arrive after a wholly calm lead-in. Sunday’s outlook included a Small Craft Advisory with 7–8-foot seas, followed by a midnight-to-3 a.m. Monday gale forecasting east winds of 35–45 knots, gusts to 55 knots and seas of 7–12 feet. The sequence matters for anyone trying to find a passage window: the storm period was bracketed by other marine hazards.⁠10

One apparent timing contradiction in the alerts does not mean the warning ended early. The records carry separate deadlines for the message and the hazard. Sunday afternoon’s message expired before the scheduled Monday storm onset; Sunday evening’s message expired at 4:45 a.m. Monday while still scheduling the storm through 9 p.m. Its encoded warning interval and event-ending field agreed with that later ending.⁠10⁠3

The Monday morning record makes the same distinction: its message expires at 2 p.m. AKST Monday, while its warning text and event-ending fields schedule the storm through midnight. An expired message alone is therefore not evidence of cancellation. Equally, this archived sequence cannot establish whether a later bulletin extended, shortened or canceled the warning.⁠27

Mariners should remain in port, alter course, and/or secure the vessel for severe conditions.

That instruction is the practical center of the forecast. Decisions about departure, course and securing a vessel need the latest warning for the actual route—not an older sea range, a neighboring zone’s forecast or a message-expiration timestamp mistaken for the end of danger. In the latest verified archived schedule, midnight marks a transition from storm to gale, not a return to safe water.

Как вышло в эфир
  1. Forecasters raised the sea forecast to 37–42 feet and extended the storm warning three hours.
  2. 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?
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.
  10. 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.
  11. 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.
  12. 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.
  13. 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.
  14. 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.
  15. 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.
  16. 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.
