Early in its existence, Lenny produced large waves and high tides along the Guajira Peninsula in Colombia, sinking two boats and flooding 1,200 houses. There were also reports of flooded businesses and damaged crops. In the country, strong winds on the storm's fringe killed a man by striking him with a beam. Although there were initial reports of nine people missing, only two were counted in the death toll for mainland Colombia. Two sailors were killed offshore when their yacht was lost in the southern Caribbean Sea.
