Meteorological Analysis
|
Danielle originated from a tropical wave which moved off the coast of Africa on
August 21st. The tropical wave moved westward under the subtropical
ridge and gradually organized, becoming a tropical depression by August 24th,
about 600 nm WSW of the Cape Verde Islands. The depression quickly
strengthened into tropical storm Danielle the same day. Danielle then
underwent rapid intensification and became a hurricane on the 25th. Danielle's
strengthening leveled off at 105 mph on the 26th, while the storm was located
900 nm E of the Leeward Islands. At this point, Danielle was moving WNW
under the subtropical ridge. This motion would continue for the next few days.
Danielle then re intensified despite shear and reached winds of 105 mph again
on the 27th. Danielle's pressure was a remarkably high 994 mb however.
Shear and cooler waters then began to take their toll on Danielle and Danielle
weakened into a 75 mph hurricane by the 30th. As Danielle turned NE on the
31st winds reached 105 mph again. A trough then accelerated Danielle to the
NE and shear increased over Danielle. Danielle passed within 200 nm of
Bermuda on September 2nd, and began to become extratropical as it passed
within 200 nm of Cape Race, Newfoundland on the 3rd. Danielle became a
fully extratropical storm on the 4th with winds of hurricane force. Danielle then
moved rapidly E and then NE due to a series of troughs over the next few days.
Danielle then affected the British isles with gale conditions, and merged with
another extratropical system on the 8th to the north of the British Isles.
