 Hurricane Kyle began as a weak area of low pressure associated with a tropical wave that moved off the west coast of Africa on September 12 . The system tracked in a general westward direction with little convective development and tracked over the Leeward Islands on September 18 . An upper @-@ level trough situated over the eastern Caribbean Sea interacted with the wave , resulting in an increase in shower and thunderstorm activity . The following day , a larger surface circulation developed as the low moved towards the northwest . The wave later became separated from the low , with the wave continuing towards the west and the low tracking to the northwest . The National Hurricane Center ( NHC ) , at this time , were not anticipating significant development of the low as strong wind shear inhibited deep convection from forming . Around 1400 UTC on September 21 , a Tropical Cyclone Formation Alert ( TCFA ) was issued for the system as convection developed around the center of circulation .
