Part of the 2015 Pacific hurricane season

Hurricane Patricia was the most intense tropical cyclone ever recorded in the Western Hemisphere and the second-most intense worldwide in terms of barometric pressure. It also featured the highest one-minute maximum sustained winds ever recorded in a tropical cyclone. Originating from a sprawling disturbance near the Gulf of Tehuantepec in mid-October 2015, Patricia was first classified a tropical depression on October 20. Initial development was slow, with only modest strengthening within the first day of its classification. The system later became a tropical storm and was named Patricia, the twenty-fourth named storm of the annual hurricane season. Exceptionally favorable environmental conditions fueled explosive intensification on October 22. A well-defined eye developed within an intense central dense overcast and Patricia grew from a tropical storm to a Category 5 hurricane in just 24 hours—a near-record pace. The magnitude of intensification was poorly forecast and both forecast models and meteorologists suffered from record-high prediction errors.

On October 23, two Hurricane Hunter missions both revealed the storm to have acquired maximum sustained winds of 205 mph (335 km/h) and a pressure of 879 mbar (hPa; 25.96 inHg). Since the peak intensity was assessed to have occurred between the missions, the National Hurricane Center ultimately estimated Patricia to have acquired winds of 215 mph (345 km/h) and pressure of 872 mbar (hPa; 25.75 inHg). This ranked it just below Typhoon Tip of 1979 as the most intense tropical cyclone on record. Patricia's exceptional intensity prompted the retirement of its name in April 2016.[1] Late on October 23, Patricia made landfall in a significantly weakened state near Cuixmala, Jalisco. Despite weakening greatly, it was the strongest recorded landfalling Pacific hurricane with winds estimated at 150 mph (240 km/h). Interaction with the mountainous terrain of Mexico induced dramatic weakening, faster than the storm had intensified. Within 24 hours of moving ashore, Patricia degraded into a tropical depression and dissipated soon thereafter late on October 24.
