The name Danielle has been used for six tropical cyclones in the Atlantic Ocean. The 2010 storm, Hurricane Danielle (06L), lasted from August 21st to August 31st.

On August 19, an area of low pressure moved off the West coast of Africa. Moving through favorable conditions, it developed into Tropical Depression Six near the Cape Verde Islands on August 21, the first of the series of Cape Verde-type storms.

On August 22 the system attained tropical storm status, thus earning the name “Danielle”. The next day it attained hurricane status, becoming the second of the season and strengthened further to a Category 2 hurricane.

On August 24, Danielle suddenly weakened from a Category 2 hurricane to a Category 1 due to unexpected dry air intrusions and westerly shear. Later that day, Danielle briefly weakened to a tropical storm, before restrengthening into a Category 1 hurricane several hours later. Hours later, Danielle restrengthened into a Category 2 and developed an eye in the morning hours of August 26.

On August 27, Hurricane Danielle strengthened to a Category 3 hurricane, becoming the first major hurricane of the season, and further strengthened to a Category 4 hurricane shortly after. Danielle later weakened to a Category 3, then Category 2 hurricane, and later became a Category 1 Hurricane due to an eyewall replacement cycle, while avoiding land areas. As the storm was moving in a northerly manner, it was not expected to strengthen any more as it would be experiencing increasing wind shear and colder surface waters.

It became extratropical early on August 31 southeast of Newfoundland without having directly impacted land. It was fully absorbed by a larger extratropical low on September 4 over Greenland. One person drowned in a rip current related to the distant hurricane near Satellite Beach, Florida.

On August 27, Hurricane Danielle (06L) strengthened to a Category 3 hurricane, becoming the first major hurricane of the season, and further strengthened to a Category 4 hurricane shortly after.

Danielle later weakened to a Category 3, then Category 2 hurricane, and later became a Category 1 Hurricane. As the storm is moving in a northerly manner, it is not expected to strengthen, since it will be experiencing increasing wind shear and colder surface waters.

The center of Hurricane Danielle is located near 38.0°N 54.5°W, about 605 miles (975 km) south of Cape Race, Newfoundland and Labrador.  The minimum central pressure is estimated to be 977 mbar (hPa, 28.85 inHg) and the storm is moving north-northeast at 29 mph (46 km/h).

Maximum sustained winds are estimated at 80 mph (130 km/h), with higher gusts. Tropical storm force winds extend outward up to 310 miles (500 km) from the center of Danielle, and hurricane force winds extend up to 85 miles (140 km) from the center. Very high surf and rip currents are likely along the northern East Coast of the United States and the coast of Atlantic Canada, through Monday.

The center of Hurricane Danielle (06L) is located near 30.3°N 59.7°W, about 330 miles (535 km) east-southeast of Bermuda.

The minimum central pressure is estimated to be 970 mbar (hPa, 28.64 inHg) and the storm is moving north-northeast at 13 mph (20 km/h).

Maximum sustained winds are estimated at 105 mph (165 km/h), with higher gusts. Tropical storm force winds extend outward up to 185 miles (295 km) from the center of Danielle, and hurricane force winds extend up to 70 miles (110 km) from the center.

Very high surf and rip currents are likely in Bermuda, along the East Coast of the United States and the coast of Atlantic Canada over the next few days.

Swells from Hurricane Danielle (06L) are expected to affect portions of the United States east coast starting Friday. The system is currently located near 25.8N 57.6W, about 625 mi (1005 km) southeast of Bermuda.

Danielle is moving toward the northwest near 12 mph (19 km/hr) and a gradual turn toward the north-northwest and north is expected during the next couple of days. On this track, the center of Danielle is expected to remain well east of Bermuda.

Maximum sustained winds remain near 110 mph (175 km/hr) with higher gusts. Danielle is a category two hurricane on the Saffir-Simpson hurricane wind scale. Danielle is expected to become a major hurricane on Friday.

Hurricane force winds extend outward up to 50 miles (85 km) from the center, and tropical storm force winds extend outward up to 205 miles (335 km). The estimated minimum central pressure is 965 mb (28.50 inches).

Hazards affecting land could include large and dangerous surf conditions in Bermuda during the next few days. Swells from Danielle will begin to arrive on the east coast of the United States on Friday. Large surf and dangerous rip currents are expected throughout the weekend.

Tropical Storm Danielle (06L) has been upgraded to a hurricane once again. The system is located about 795 mi (1275 km) east of the Leeward Islands. It is moving toward the west-northwest near 18 mph (30 km/hr), but is expected to slow down and turn toward the northwest during the next couple of days.

Maximum sustained winds have increased to near 75 mph (120 km/hr) with higher gusts. Danielle is thus a category one hurricane on the Saffir-Simpson hurricane wind scale. Little change in strength is expected tomorrow, with some strengthening possible by Thursday.

Hurricane force winds extend outward up to 30 miles (45 km) from the center and tropical storm force winds extend outward up to 140 miles (220 km). The estimated minimum central pressure is 990 mb (29.23 inches).
