2023 Pacific hurricane season

The 2023 Pacific hurricane season is an ongoing event in the annual tropical cyclone season in the northern hemisphere. The season officially began on May 15 in the Eastern Pacific Ocean, and will begin on June 1 in the Central Pacific; both will end on November 30. These dates historically describe the period each year when most tropical cyclones form in the Pacific Ocean basin and are adopted by convention. However, the formation of tropical cyclones is possible at any time of the year.

Forecasts include weekly and monthly changes in important factors that help determine the number of tropical storms, hurricanes, and major hurricanes within a particular year. According to the National Oceanic and Atmospheric Administration (NOAA), the average hurricane season in the Eastern and Central Pacific between 1991 and 2020 contained approximately 15 tropical storms, 8 hurricanes, and 4 major hurricanes. The NOAA generally classifies a season as above average, average, or below average based on the cumulative ACE index, but occasionally the number of tropical storms, hurricanes, and major hurricanes within a hurricane season is also considered. Since 2017, the National Hurricane Center (NHC) changed its policy to permit issuance of advisories on disturbances that were not yet tropical cyclones but had a high chance to become one, and were expected to bring tropical storm or hurricane conditions to landmasses within 48 hours. As a result of this change, watches and warnings could be issued by local authorities. Such systems would be termed as "Potential Tropical Cyclones".[4]

On May 4, 2023, the Servicio Meteorológico Nacional issued its forecast for the season, predicting a total of 16–22 named storms, 7–11 hurricanes, and 3–5 major hurricanes to develop.[3] Factors they expected to increase activity were above-average sea surface temperatures across the eastern Pacific and the El Niño–Southern Oscillation (ENSO) remaining in the neutral phase, with the possibility of a strong El Niño developing.

Storm names

The following names will be used for named storms that form in the northeastern Pacific Ocean during 2023. Retired names, if any, will be announced by the World Meteorological Organization during the joint 46th Sessions of the RA IV Hurricane Committee in the spring of 2024. The names not retired from this list will be used again in the 2029 season.[5] This is the same list used in the 2017 season.

For storms that form in the Central Pacific Hurricane Center's area of responsibility, encompassing the area between 140 degrees west and the International Date Line, all names are used in a series of four rotating lists.[6] The next four names that will be slated for use in 2023 are shown below.

Season effects

This is a table of all the storms and that have formed in the 2023 Pacific hurricane season. It includes their duration, names, landfall(s), denoted in parentheses, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a tropical wave, or a low, and all the damage figures are in 2023 USD.
