Hurricane Lili was the third of only four Atlantic tropical cyclones on record to reach hurricane status in the month of December with the others being an unnamed hurricane in 1887, December 1954's Alice, and 2005's Epsilon. The final of thirteen tropical storms in the 1984 Atlantic hurricane season, Lili developed as a subtropical cyclone which originated from a frontal trough to the south of Bermuda on December 12. It tracked southeastward, then northward, slowly attaining tropical characteristics and becoming a hurricane on December 20. Lili turned to the south and southwest, briefly threatening the northern Caribbean islands before weakening and dissipating near the coast of the Dominican Republic. The storm produced light rainfall but no damage.
