1898
The U.S. Weather Bureau established a West Indies hurricane
warning network.
1926
Ships, island stations, surface charts, telegraph, radio, warning
flags and newspapers carried the warning story.
Mid-century
Aircraft reconnaissance, coastal radar and then weather satellites
added direct views unavailable to Gray’s office.
2002
The National Hurricane Center introduced the familiar track
forecast cone.
Today
The cone shows probable center-track uncertainty, while separate
products communicate wind, surge, rainfall and local hazards.
The cone is deliberately not a storm-size outline. NHC constructs it
from circles based on historical official forecast errors; about 60–70
percent of historical center tracks fall within the cone. Hazardous
conditions can occur far outside it.
