The 2019 Atlantic hurricane season is an ongoing event in the annual formation of tropical cyclones in the Northern Hemisphere. The season officially began on June 1, 2019, and will end on November 30, 2019. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, tropical cyclogenesis is possible at any time of the year, as demonstrated by the formation of Subtropical Storm Andrea on May 20, marking the record fifth year in a row where a tropical or subtropical cyclone developed before the official start of the season, breaking the previous record of four years set in 1951–1954.[1]

Ahead of and during the season, several national meteorological services and scientific agencies forecast how many named storms, hurricanes, and major hurricanes (Category 3 or higher on the Saffir–Simpson scale) will form during a season and/or how many tropical cyclones will affect a particular country. These agencies include the Tropical Storm Risk (TSR) Consortium of University College London, the National Oceanic and Atmospheric Administration (NOAA) and Colorado State University (CSU). The forecasts include weekly and monthly changes in significant factors that help determine the number of tropical storms, hurricanes, and major hurricanes within a particular year. Some of these forecasts also take into consideration what happened in previous seasons and the state of the El Niño–Southern Oscillation (ENSO). On average, an Atlantic hurricane season between 1981 and 2010 contained twelve tropical storms, six hurricanes, and three major hurricanes, with an Accumulated Cyclone Energy (ACE) index of between 66 and 103 units.[2]

Pre-season outlooksEdit

The first forecast for the year was released by TSR on December 11, 2018, which predicted a slightly below-average season in 2019, with a total of 12 named storms, 5 hurricanes, and 2 major hurricanes, due to the anticipated presence of El Niño conditions during the season.[3] On April 4, 2019, CSU released its forecast, predicting a near-average season of 13 named storms, 5 hurricanes and 2 major hurricanes.[4] On April 5, TSR released an updated forecast that reiterated its earlier predictions.[5] North Carolina State University released their forecast on April 16, predicting slightly-above average activity with 13–16 named storms, 5–7 hurricanes and 2–3 major hurricanes.[6] On May 6, The Weather Company predicted a slightly-above average season, with 14 named storms, 7 hurricanes, and 3 major hurricanes.[7] The UK Met Office released their forecast May 21, predicting 13 named storms, 7 hurricanes, 3 major hurricanes and an Accumulated Cyclone Energy of 109 units.[8] On May 23, NOAA released their first prediction, calling for a near-normal season with 9–15 named systems, 4–8 hurricanes, and 2–4 major hurricanes.[9] On May 30, TSR released an updated forecast which increased the number of forecast hurricanes from 5 to 6.[10]

Mid-season outlooksEdit

On June 4, CSU updated their forecast to include 14 named storms, 6 hurricanes and 2 major hurricanes, including Subtropical Storm Andrea.[11] On June 11, University of Arizona (UA) predicted above-average activities: 16 named storms, 8 hurricanes, 3 major hurricanes, and Accumulated Cyclone Energy index of 150 units.[12]

Seasonal summaryEdit

Saffir–Simpson scale 

For a record fifth consecutive year, activity began before the official start of the season when Subtropical Storm Andrea formed on May 20.

The Accumulated Cyclone Energy index for the 2019 Atlantic hurricane season, as of Andrea's final advisory, is 0.245 units.[nb 1]


Subtropical Storm AndreaEdit

Subtropical storm (SSHWS)
DurationMay 20 – May 21
Peak intensity40 mph (65 km/h) (1-min)  1006 mbar (hPa)

On May 17, the National Hurricane Center (NHC) began forecasting the formation of an area of low pressure south of Bermuda, which had the potential to later develop into a tropical or subtropical cyclone.[13] On the following day, a large and elongated area of clouds and thunderstorms developed well to the east of the Bahamas.[14] The disturbance gradually organized over the next two days as it moved westward and then northward, though it still lacked a well-defined circulation. However, an Air Force Reconnaissance flight late on May 20 revealed that the storm had a well-defined center with winds reaching gale force, due to being involved with an upper-level low to its west, leading to the classification of the system as Subtropical Storm Andrea at 22:30 UTC that day.[15] Soon afterward, Andrea reached its peak intensity.[16] The nascent storm did not last very long, as the storm encountered dry air from the south and southerly wind shear. These hostile conditions caused Andrea's convection to dissipate, and the storm degenerated into a remnant low a day later.[17][18]

Storm namesEdit

The following list of names will be used for named storms that form in the North Atlantic in 2019. Retired names, if any, will be announced by the World Meteorological Organization in the spring of 2020. The names not retired from this list will be used again in the 2025 season. This is the same list used in the 2013 season, with the exception of the name Imelda, which replaced Ingrid.

Season effectsEdit

This is a table of all the storms that have formed in the 2019 Atlantic 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 USD. Potential tropical cyclones are not included in this table.
