Treat thunderstorm hazards as a combined wind, wave, visibility and lightning problem; use official warnings and current observations.

For non-tropical marine conditions, a Gale Warning generally concerns sustained winds or frequent gusts of 34 to 47 knots.

Use the live NWS warning as authority, not a locally inferred badge.
