FAQ

How far back does the data go?

The IBTrACS record begins in 1842 for the North Atlantic basin, with global coverage from the 1960s onward when satellite monitoring began.

What storm attributes are included?

Each track record includes storm position, maximum sustained wind speed, minimum central pressure, storm status (tropical depression, storm, hurricane), and basin of origin.
