Hurricane Rick was the third-strongest Pacific hurricane by maximum sustained winds, tied with Hurricane Polo, and the fourth-most intense by central pressure. Developing off the southern coast of Mexico on October 15, Rick traversed an area with favorable environmental conditions, favoring rapid intensification, allowing it to become a hurricane within 24 hours of being declared a tropical depression. An eye began to form during the afternoon of October 16; once fully formed, the storm underwent another period of rapid strengthening. During the afternoon of October 17, the storm attained Category 5 status on the Saffir–Simpson hurricane wind scale. Several hours later, Rick attained its peak intensity with winds of 180 mph (285 km/h) and a barometric pressure of 906 mbar. Category 5 hurricane: peak winds of 180 mph (155 knots), lowest pressure 906 mb. October 15 – October 21, 2009. Landfall: October 21 at 60 mph, 23.3°N 106.5°W. Accumulated cyclone energy: 21.6.
