Alaska marine forecasts: common questions
Is there a small craft advisory off Alaska right now?
78 of the 113 Alaska marine zones are under an active advisory or warning, Adak to Kiska Bering Side (small craft advisory), Adak to Kiska Pacific Side (small craft advisory), Barren Islands East (gale warning), Bristol Bay from Cape Chichagof to Cape Pierce (small craft advisory) and 74 others. Each zone page shows the expiry time and the full text.
How windy is it on the Alaska coast right now?
Buoys off Alaska are reporting 0 to 27 knots, the strongest at North Side of Saint Lawrence Island. A knot is 1.15 mph, so 20 knots is about 23 mph. Wind measured offshore is usually stronger than the same wind felt in a harbor.
How rough are the seas off Alaska today?
The highest seas measured right now are 6 ft off Nikolski to Seguam Pacific Side (15-75 nm), out of the 14 of 113 Alaska zones with a wave-capable buoy nearby. Seas are significant wave height, the average of the highest third of the waves, so individual waves run noticeably higher than the figure.
Who issues the marine forecast for Alaska?
The National Weather Service, from its Anchorage Alaska office, its Fairbanks, AK office and its Juneau, AK office. Each of the 113 zones on this page gets its own bulletin in a legacy teletype format, reproduced here in full underneath the charts and the live buoy readings.
