A tropical disturbance in the eastern Caribbean Sea was in an area not expecting any development in the second week of October. While drifting across the region, upper-level winds calmed down enough for the tropical disturbance to strengthen and to develop into Tropical Depression Fifteen on October 13. It strengthened to Tropical Storm Omar the next day. Omar quickly strengthened into a 70 mph (110 km/h) storm that afternoon, and became a hurricane that night. It remained a hurricane through that night and it changed little in intensity through the next day, but that evening Omar intensified quickly and became a 115 mph Category 3 storm, and became a 125 mph (205 km/h) storm the next morning. Omar became a weak Category 4 early that morning. However, wind shear and dry air quickly weakened Omar to a minimal hurricane that afternoon as it raced towards the northeast at 26 mph (41 km/h). After dropping to tropical storm strength it became a hurricane again on October 17. It degenerated to a remnant low on October 18.
