Advisories are numbered consecutively for each storm and describe
the present and forecast position and storm intensity. Advisories
are issued at six-hour intervals - at 11 p.m., 5 a.m., 11 a.m. and
5 p.m. Bulletins provide additional information. Each message gives
the name, eye position, intensity and forecast movement of the tropical
cyclone.
Hurricane eye positions are given by latitude (for example: 13.2 degrees North)
and longitude (for example: 57.8 degrees West) to the nearest one-tenth of
one degree. When the storm moves within radar range, eye position may also
be given as statute miles and compass direction from a specified point.
Because hurricanes change direction very quickly, you should concentrate more
on where the storm is supposed to go than where it has been.
