storm warning

  1. A warning of sustained winds of 48 knots (55 mph) or more either predicted or occurring, not associated with tropical cyclones.

    The storm-warning signals for this condition are 1) one square red flag with black center by day and 2) two red lanterns at night.

  2. Prior to 1 January 1958, a warning, for marine interests, of impending winds of from 28 to 63 knots (32 to 72 mph).

  3. A message in plain language broadcast to all Navy ships and merchant ships over appropriate Fleet Broadcasts.

    The warning gives information on the position, movement, intensity, etc., of a low pressure center.
    See small-craft warning, gale warning, whole-gale warning, hurricane warning.
