 Lili continued generally southward , reaching its peak intensity of 80 mph ( 130 km / h ) . Higher pressures developed to its northeast , resulting in the hurricane to accelerate to the southwest . On December 22 , Lili finished executing its large cyclonic loop by passing over the same location it passed one week prior . The combination of its increased forward speed , as well as increased levels of vertical wind shear , created an unfavorable environment which caused steady weakening . On December 23 , Lili weakened to a tropical storm while located 430 miles ( 690 km ) northeast of Antigua . It rapidly lost organization as it approached the Leeward Islands , and dissipated just off the coast of the Dominican Republic on December 24 .
