Louisiana marine forecasts: common questions
Is there a small craft advisory off Louisiana right now?
No advisory or warning is in force in any of the 24 Louisiana marine zones at the moment. Advisories are issued per zone by the National Weather Service and appear at the top of a zone's page as soon as one is posted.
How windy is it on the Louisiana coast right now?
Buoys off Louisiana are reporting 4 to 12 knots, the strongest at Stake Island LA to Southwest Pass of the Mississippi River (20-60 nm). 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 Louisiana today?
The highest seas measured right now are 1 ft off Barataria Bay, out of the 16 of 24 Louisiana 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 Louisiana?
The National Weather Service, from its Lake Charles, LA office and its New Orleans, LA office. Each of the 24 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.
