As part of their annual tropical cyclone activity, the agency issues a tropical cyclone report on every tropical cyclone in the Atlantic and Eastern Pacific Ocean basins, which are available since 1958 and 1988, respectively. The report summarizes the synoptic history, meteorological statistics, casualties and damages, and the post-analysis best track of a storm. The reports were formally known as Preliminary Reports up until 1999. The agency maintains archives and climatological statistics on Atlantic and Pacific hurricane history, including annual reports on every tropical cyclone, a complete set of tropical cyclone advisories, digitized copies of related materials on older storms, season summaries published as the Monthly Weather Review, and HURDAT, which is the official tropical cyclone database.
