The National Hurricane Center and Central Pacific Hurricane Center's Tropical Cyclone Reports (TCRs) contain information on all tropical (and subtropical) cyclones that have occurred within the Atlantic, eastern Pacific, and central Pacific basins, including synoptic history, meteorological statistics, casualties and damages, and the post-analysis best track (six-hourly positions and intensities). As of 2023, comprehensive versions of these reports are provided for all tropical cyclones in which coastal watches and warnings were in effect or direct fatalities were reported, and for other select storms with significant public or research interest (e.g., storms investigated via research field campaigns). Otherwise, abbreviated TCRs are produced that include a short description of the cyclone’s origin, justification of the analyzed maximum winds and minimum pressure, noteworthy statistics, and the post-analysis best track. The abbreviated TCRs also contain the full suite of tables and figures that are included in the comprehensive reports. Tropical cyclones include depressions, storms, and hurricanes. Tropical depressions included below are those that did not reach tropical storm strength. Potential tropical cyclones listed below are disturbances that NHC issued advisories on based on their threat to land, but which failed to develop into tropical cyclones.

Season Summary

2023 Eastern Pacific Summary Table (PDF)

^ Peak Intensity Reached Outside of East Pacific

^a Tropical depression (TD) or Subtropical Depression (SD), maximum sustained winds 33 kt or less; tropical storm (TS) or Subtropical Storm (SS), winds 34-63 kt; hurricane (HU), winds 64-95 kt; major hurricane (MH), winds 96 kt or higher.

^b Dates begin at 0000 UTC and include all tropical and subtropical cyclone stages; non-tropical stages are excluded except for PTCs which have no tropical stages.

^c Accumulated Cyclone Energy is an index that is defined as the sum of the squares of the maximum sustained surface wind speed (knots) measured every six hours for all named storms while they are at least tropical storm intensity. Note the ACE total in this table is only for the basin being summarized (e.g., 140°W–180° in the Central Pacific).

^d Deaths occurring as a direct result of the forces of the tropical cyclone are referred to as “direct” deaths. These would include those persons who drowned in storm surge, rough seas, rip currents, and freshwater floods. Direct deaths also include casualties resulting from lightning and wind-related events (e.g., collapsing structures).

^e U.S. damage totals are based on values provided by the NOAA National Centers for Environmental Information (NCEI).
