The 2018 Atlantic hurricane season is an ongoing event in the annual formation of tropical cyclones in the Northern Hemisphere. The season will officially begin on June 1, 2018, and end on November 30, 2018. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, the formation of tropical cyclones is possible at any time of the year, as shown by the formation of Subtropical Storm Alberto on May 25, the fourth consecutive year a storm developed before the official start of the season.

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 an ongoing La Niña event that had recently formed in November 2017. 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.
The first forecast for the year was released by TSR on December 7, 2017, which predicted a slightly above-average season in 2018, with a total of 15 named storms, 7 hurricanes, and 3 major hurricanes. On April 5, 2018, CSU released its forecast, predicting a slightly above-average season with 14 named storms, 7 hurricanes, and 3 major hurricanes. On the same day TSR released its second forecast, predicting a slightly-below average hurricane season, with 12 named storms, 6 hurricanes, and 2 major hurricanes, the reduction in both the number and size of storms compared to its first forecast being due to recent anomalous cooling in the far northern and tropical Atlantic. Several days later, on April 16, North Carolina State University released its predictions, forecasting an above-average season, with 14–18 named storms, 7–11 hurricanes, and 3–5 major hurricanes. On April 19, The Weather Company released its first forecasts, predicting 2018 to be a near-average season, with a total of 13 named storms, 7 hurricanes, and 2 major hurricanes. On May 24, NOAA released their first forecasts, calling for a near to above average season in 2018.

A broad area of low pressure formed over the southwestern Caribbean Sea on May 21, as the result of the interaction between an upper-level low and a weak surface trough. The low drifted slowly westward and then northward through the Caribbean Sea as it gradually organized. By 15:00 UTC on May 25, the strongly sheared low had organized sufficiently to be classified as Subtropical Storm Alberto while situated about 55 miles (90 km) south of Cozumel, Quintana Roo. After remaining nearly stationary for the next day, Alberto began to move northwards.
As of 4:00 p.m. CDT (21:00 UTC) May 26, Subtropical Storm Alberto is located within 30 nautical miles of , about 95 miles (155 km) north of the western tip of Cuba or about 170 miles (275 km) southwest of the western tip of the Dry Tortugas. Maximum sustained winds are 35 knots (40 mph; 65 km/h), with gusts up to 45 knots (50 mph; 85 km/h). The minimum barometric pressure is 999 mbar (hPa; 29.50 inHg), and the system is moving north at 13 mph (20 km/h). Winds of 40 mph extend outward up to 140 miles (220 km) from the center of Alberto. The storm is expected to strengthen through the Gulf of Mexico .

The following list of names is being used for named storms that form in the North Atlantic in 2018. Retired names, if any, will be announced by the World Meteorological Organization in the spring of 2019. The names not retired from this list will be used again in the 2024 season. This is the same list used in the 2012 season, with the exception of the name Sara, which replaced Sandy.
This is a table of all the storms that have formed in the 2018 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.
