Hurricane and Tropical Storm Watch/Warning Breakpoints
The National Hurricane Center, in coordination with other National Weather
Service forecast offices, is responsible for issuing, changing and ending
U.S. coastal hurricane and tropical storm watches and warnings. The
meteorological services of other countries are responsible for watches and
warnings in their own lands.
The coastal areas placed under tropical storm and hurricane watches and
warnings are described through the use of "breakpoints" or geographical
positions. The National Hurricane Center maintains a list of pre-arranged
breakpoints for the U.S. Atlantic and Gulf coasts, Mexico, Cuba and the
Bahamas. Other sites are unofficial and sites not on the list can be
selected if conditions warrant.
Here is the 2003 list of international breakpoints for Atlantic and
Eastern Pacific tropical cyclones.
