On May 18th, a low pressure system stalled just off the coast of South Carolina, and developed. On May 19th, it quickly gained tropical characteristics, and was named Tropical Storm Alberto (01L) that afternoon. Soon afterwards, Tropical Storm Alberto quickly began to strengthen, as it slowly moved southwestwards, closer to the South Carolina coast.

Alberto is the first named storm in May, in the Atlantic basin, since Arthur in 2008, and the earliest tropical storm (with non-subtropical origins) since Ana in April 2003. Combined with Aletta’s preseason development in the northeast Pacific ocean, this became the first occurrence where systems reached tropical storm status in both the Atlantic and East Pacific basins, prior to the official start date of their respective hurricane seasons.

As of 6:50 p.m. EDT (2250 UTC) May 19, Tropical Storm Alberto is located within 30 nautical miles of 32.2°N 77.9°W, about 140 mi (225 km) east-southeast of Charleston, South Carolina and about 120 mi (195 km) south of Cape Fear, North Carolina. Maximum sustained winds are 50 knots (60 mph, 95 km/h), with stronger gusts. Minimum central pressure is 995 mbar (hPa; 29.38 InHg), and the system is moving southwest at 3 kt (3 mph, 6 km/h).
