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).

Bill Expected to Weaken but Still Produce Strong Winds over N. Atlantic

At 5:00 AM AST (0900 UTC) the center of Tropical Storm Bill was located about 190 miles (305 km) northeast of Cape Race, Newfoundland.

Bill is moving toward the east-northeast near 43 mph (69 km/hr). An east-northeast motion with some increase in forward speed is expected during the next day or two.

Maximum sustained winds are near 70 mph (110 km/hr) with higher gusts. The system has lost its tropical characteristics, and gradual weakening is forecast during the next couple of days.

Even though Bill is no longer a tropical cyclone, it is expected to produce a large area of storm and gale force winds over the North Atlantic during the next day or two. Currently, tropical storm force winds extend outward up to 315 miles (510 km) from the center. Estimated minimum central pressure is 980 mb (28.94 inches).

Hurricane Bill Strengthens to Category 4 Storm

Bill (02L) has strengthened to a Category Four Hurricane, whose center is located about 460 miles (740 km) east of the Leeward Islands.

Bill is moving toward the west-northwest near 16 mph (26 km/hr) and a gradual turn toward the northwest is expected during the next 24 to 48  hours. On this track, the core of this dangerous hurricane will be passing well to the northeast of the northern Leeward Islands late today and early Thursday.

The animated image shows the movement of Bill today and its well-developed eye. The still image, on the other hand, shows the temperatures of the Atlantic Ocean and the past and forecast track of the hurricane, which is expected to move northwest towards warmer waters.

Maximum sustained winds are near 135 mph (215 km/hr) with higher gusts. Bill is a category four hurricane on the Saffir-Simpson scale, with some additional strengthening forecast during the next 24 hours.

Hurricane force winds extend outward up to 45 miles (75 km) from the center, and tropical storm force winds extend outward up to 175 miles (280 km). The estimated minimum central pressure is 948 mb (27.99 inches).

Large swells associated with Bill will be impacting the islands of the northeast Caribbean Sea during the next day or two. Large swells associated with Bill should also begin to affect Bermuda and portions of the southeastern coast of the United States Friday and Saturday.

Hurricane Bill is strengthening as it continues moving west-northwestward.
At 1100 am AST (1500 UTC) the center of Hurricane Bill was located near latitude 14.1 north longitude 45.2 West or about 1080 miles (1735 km) East of the Lesser Antilles.

Hurricane Bill is moving toward the west-northwest near 16 mph (26 km/h) and this motion is expected to continue for the next couple of days.

Maximum sustained winds have increased to near 90 mph 150 km/h with higher gusts. Some strengthening is forecast during the next 48 hours and Hurricane Bill could become a major hurricane by Wednesday.

Hurricane force winds extend outward up to 30 miles (45 km) from the center and tropical storm force winds extend outward up to 145 miles (230 km). The estimated minimum central pressure is 977 mb (28.85 inches).
