Meteorological Analysis
|
Felix originated from a tropical wave which left the coast of Africa on September
5th. A low associated with the wave started to become more vigorous almost
immediately after leaving Africa, and convection started to wrap around the
low. On September 7th the low organized into tropical depression 7, about
360 nm SW of the Cape Verde Islands. The depression then moved west at
up to 20 kt under a strong subtropical ridge. This inhibited development and
by the 8th the depression degenerated into a tropical wave, about 650 nm WSW
of the Cape Verde Islands. Shear decreased over the wave eventually and the
wave slowed. This allowed the wave to organize convection near its mid-level
center. The vorticity in the mid levels translated to the surface on September
10th and the wave became a tropical depression again. The depression
continued to move WNW and strengthened into tropical storm Felix by the 11th.
Felix then began to turn more northerly due to a weakness in the subtropical
ridge and became a hurricane on September 13th under favorable
environmental conditions. Felix then underwent rapid intensification as the eye
and eye wall became more defined, and Felix reached its maximum strength of
115 mph with a pressure of 962 mb on the 14th. A trough approached Felix
at this point and Felix turned NE in response to it. Shear, dry air, and cooler
waters then began to weaken Felix. Felix weakened into a tropical storm on
the 17th about 350 nm SW of the Azores. Felix then stalled causing even more
rapid weakening. Felix weakened into a tropical depression by the 18th and
dissipated about 400 nm SW of the Azores on the 19th.
