Meteorological Analysis
|
Danny originated from a tropical wave which moved off the coast of Africa on July 9th. The
wave was initially well organized but, when it hit cooler waters north of 10 N it lost all
organization and became only a wind shift. The wave split, with half of it moving west and
half of it moving northwest. The one heading northwest began to generate convection near
a mid-level circulation along its axis on the 13th. Convection continued to organize, and
vorticity translated to the surface by the 16th, forming a surface circulation. The wave
became tropical depression 5 shortly afterwards 550 nm E of Bermuda. Convective banding
improved and on July 17th the depression became tropical storm Danny. Danny was being
influenced by a large ridge over the center of the ocean, causing the storm to go NW, N,
and then NE by the 18th. Danny then moved over a patch of warm water and an eye
feature formed, Danny was declared a 75 mph hurricane on the 18th. Danny then began to
move eastward around the ridge on the 19th and it began to encounter shear. This was the
beginning of a slow weakening trend. Danny then moved over cooler waters on the 20th,
and combined with shear caused Danny to rapidly weaken. Danny became a tropical
depression on the 19th as it turned SE. Danny degenerated into a remnant low by the 21st.
The remnant low then moved south and west around the ridge. The low fired some
convection on the 26th but, it was short lived due to dry air. Danny then dissipated on the
27th about 1080 nm E of Bermuda.
