This option allows the user to specify Alert Conditions based the actual and/or forecast position of a storm.

The data fields which define this data are:

Description - Description of the geographical area

Graphical Area Select – This command presents the user with a large map whereby via mouse commands they can easily select a geographical area.  After accepting the area, the map corner latitude and longitudes are automatically filled in.  This is much easier than defining them manually.

NW Corner Latitude - The geographical area defined must be in the shape of a rectangle.  This defines the latitude of the NW corner of that rectangle.

NW Corner Longitude - The area defined must be in the shape of a rectangle.  This defines the longitude of the NW corner of that rectangle.

SE Corner Latitude - This defines the latitude of the SE corner of the geographical rectangle.

SE Corner Longitude - This defines the longitude of the SE corner of the geographical  rectangle.

Remember... longitudes in the Western Hemisphere are negative so values decrease as you move westward.
