After moving ashore, Beryl (02L)  quickly weakened to a tropical depression. Due to the weakening of the ridge to the north, the storm slowed and dropped heavy rainfall along its path. An approaching cold front turned Beryl to the north and northeast on May 29, and despite being well inland, the depression retained enough convection to remain a tropical cyclone.

As Beryl approached the Atlantic Ocean on May 30, its convection increased to the south and east of the center, although the intrusion of dry air resulted in a ragged appearance on satellite imagery. The approaching front caused the depression to accelerate northeastward. Beryl’s circulation became elongated and its associated convection spread northward, suggesting the transition into an extratropical cyclone.

As of 5 p.m. EDT (2100 UTC) May 29, Tropical Depression Beryl (02L) is located within 20 nautical miles of 31.8°N 82.5°W, about 40 mi (60 km) north of Waycross, Georgia, and about 85 mi (135 km) west-southwest of Savannah, Georgia. Maximum sustained winds are 25 knots (30 mph, 45 km/h), with stronger gusts. Minimum central pressure is 1005 mbar (hPa; 29.68 InHg), and the system is moving northeast at 7 kt (8 mph, 13 km/h).

After making landfall near Jacksonville Beach, Fla. at 12:10 am EDT early Monday morning, Beryl weakened to a tropical depression later in the day over north Florida and south Florida. However, inland flooding is still a significant danger as rainfall from Beryl drenches previously drought-stricken areas and potentially leading to flash-floods.

A broad swath of 2-5″ of total rainfall is expected to follow generally north and northeast of the path of Beryl through late Wednesday night. Also, any rainbands south of the center of Beryl also have the potential to stall over local areas, dumping over 2″ of rain in an hour.

On May 23, an elongated low pressure area developed over the northwestern Caribbean Sea, with disorganized thunderstorms, and began moving northeastwards. Initially, there was no well-defined center, and wind shear was unfavorable for development.

By the next day, the system extended into the Florida Straits, and the National Hurricane Center noted the potential for more favorable conditions within two days. The low became better-defined over the Florida Keys, and the cloud pattern organized.

As the system moved into the western Atlantic, a band of convection persisted across the Bahamas, where 9.7 in (250 mm) of precipitation was reported in Freeport, and in Cuba, where upwards of 20 in (510 mm) of rains caused mudslides. Additionally, the system dropped locally heavy rainfall in South Florida, reaching 9.7 inches (250 mm) in Miami.[23]

After continuing to the northeast, the system developed a well-defined circulation with associated convection, located beneath an upper-level low. Based on the observations, the National Hurricane Center initiated advisories on Subtropical Storm Beryl at 0300 UTC on May 26 when the system was located about 305 mi (490 km) east of Charleston, South Carolina. Little change in strength occurred until May 27, when Beryl transitioned into a fully tropical storm and reached its peak with winds of 70 mph (110 km/h), the same intensity it made landfall with near Jacksonville Beach, Florida. The system weakened to a tropical depression shortly afterwards.

As of 5 p.m. EDT (2100 UTC) May 28, Tropical Depression Beryl is located about 10 mi (20 km) east of Valdosta, Georgia and about 150 mi (240 km) southwest of Savannah, Georgia. Maximum sustained winds are 25 knots (30 mph, 45 km/h), with stronger gusts. Minimum central pressure is 1003 mbar (hPa; 29.62 InHg), and the system is moving north-northwest at 4 kt (5 mph, 7 km/h).
