A tropical wave moved off the coast of Africa on the 18th of
September and moved
uneventfully across the Atlantic. It interacted with an upper low that had previously
provided/been carved out by the outflow channels for Bonnie and Danielle. A closed
upper low developed in the trough axis, which helped form the tropical depression
north of Hispaniola on the 27th. The system moved west-northwest and increased in
intensity into a tropical storm on the 29th. The track shifted on a more easterly course
ahead of a cold front, and the system eventually weakened in early October as it
paralleled its prior course, becoming a frontal wave on the 3rd. Its track is below,
supplied by the National Hurricane Center.
The graphics below show the storm total rainfall for Earl...data
by the National Climatic
Data Center in Asheville, NC. Northeasterly shear induced by an upper cyclone to its east drew
thunderstorms forming in its southwest quadrant into Martin and Palm Beach counties.
