The apparatus includes a map with a rotatable warning indicator attached thereto.The warning indicator has one or more warning areas marked thereon and preferably color coded. The warning indicator also includes at least one wind direction indicator which may be aligned with a heading on the map which corresponds to the actual wind condition.
