Isidore formed at the western end of a stationary frontal zone near the Bahamas.  As a frontal wave,
gale force winds were reported on the afternoon of the 24th on the north coast of Hispaniola.
Convection began to organize near the center, and the system had converted to a tropical
depression on the 25th.  As the system moved through the central Bahamas, the depresssion
strengthened into a tropical storm.  Isidore made landfall near Jupiter, Florida as a tropical storm,
and moved through the Florida peninsula over the next 36 hours losing little strength.  It then
accelerated east-northeast ahead of a frontal zone on the 29th and 30th, losing its identity on the
1st.  Below is the track of this cyclone, provided by the National Hurricane Center.
