Today: Southeast winds 10 to 15 knots. Seas 2 to 3 feet. Wave Detail: Southeast 3 feet at 5 seconds.
Is there a small craft advisory for Lower Atchafalaya River–Intracoastal City (20-60 nm)?
No advisories, warnings or watches are in effect for NWS zone GMZ475 as of the last update on this page. Advisories can be issued at any time; check the current bulletin before leaving the dock.
What do the wind speeds in knots mean?
One knot is 1.15 mph. The National Weather Service issues a small craft advisory for sustained winds of roughly 22–33 knots or hazardous seas, a gale warning at 34–47 knots, and a storm warning at 48 knots and above. Exact advisory thresholds vary by forecast office and by water body — a bay reaches dangerous chop at a lower wind speed than open ocean.
