Definition
Hurricane Otis was a tropical cyclone that attained Category 5 status on the Saffir‑Simpson Hurricane Wind Scale and made landfall on the Pacific coast of Mexico in October 2023, resulting in severe damage and loss of life.
Overview
Hurricane Otis originated from a tropical wave that entered the Eastern Pacific basin on 22 October 2023. The system organized into a tropical depression later that day and was designated Tropical Storm Otis on 23 October. Otis underwent an unusually rapid intensification, escalating from a tropical storm to a high‑end Category 5 hurricane within a 24‑hour period. On 25 October 2023, Otis made landfall near Acapulco, Guerrero, with maximum sustained winds of 165 mph (260 km h⁻¹) and a minimum central pressure estimated at 923 mb. The storm caused widespread structural damage, extensive flooding, and power outages across Guerrero and neighboring states. Official reports confirmed at least 80 fatalities, with many more injured and displaced. The Mexican government declared a state of emergency and mobilized federal and local resources for rescue, relief, and reconstruction efforts. Post‑storm assessments highlighted the storm’s unprecedented rapid intensification close to the coast as a key factor in the high impact.
Etymology / Origin
The name “Otis” is part of the pre‑determined list of names used by the National Hurricane Center for tropical cyclones in the Eastern Pacific basin. The list, which rotates every six years, includes names derived from a variety of linguistic origins. In this context, “Otis” is a masculine given name of Greek origin meaning “keen‑sighted,” but its selection for the storm name does not convey any particular meaning beyond being part of the rotating roster.
