Meteorological Analysis
|
Franklin originated from a tropical wave which left the coast of Africa on July 10th. The wave
was suppressed from forming as it crossed the ocean due to cool waters and shear. When
the tropical wave was north of Hispanolia on the 18th, the wave split in two. The southern
portion became Gert. The northern portion of the wave which stayed behind began to
develop convection under lessening shear. The area of convection then moved into the
Bahamas and pressures fell. Initially a mid-level circulation formed, but by the 21st a
surface circulation was observed and a tropical depression formed. The depression was
about 50 nm from the northwestern Bahamas. The depression quickly strengthened and
by July 22nd it became tropical storm Franklin, with winds of 45 mph. Franklin then moved
erratically as it interacted with a weakness in the sub-tropical ridge. Franklin was hindered
at this time from shear due to Gert. Shear abated on the 23rd and Franklin reached max
winds of 70 mph. The storm began to recurve at this time to the north east but, the trough
inducing the re-curvature didn't quite catch Franklin and Franklin ended up meandering
until the 25th. Shear weakened Franklin at this time down to 40 mph, and Franklin's center
became exposed. On the 26th, Franklin began to move east again and bypassed Bermuda
by 200 nm. Franklin's tropical storm force winds stayed offshore. Franklin then turned
north again and strengthened as shear lessened again. Franklin reached wind speeds of
60 mph on the 28th. By the 29th, a front finally caught Franklin and pushed it out to sea.
Franklin passed Nova Scotia at a distance of 300 nm and dissipated on the 31st.
