The first line of the file gives the title and the date/time (GMT) the file was produced.

The next line is a data passage header.  The first field is the number of lon/lat points defining a polygon.  The second field is the threat level: 0 = possible, 1 = likely, and 2 = imminent or already occurring.  The remaining fields indicate the period over which the threat exists.
The next and "number of lon/lat points" lines are the longitude and latitude of the polygon vertices.
Multiple polygons can be defined with either the same or different threat levels.
