1899 San Ciriaco hurricane
Hurricane San Ciriaco set many records on its path. Resulting in at least 3,369 deaths in Puerto Rico, the storm was the deadliest hurricane to hit the island and the strongest at the time, until the Hurricane San Felipe Segundo made landfall in 1928 as a Category 5 hurricane. It was also among the deadliest Atlantic hurricanes ever recorded.
Meteorological history of Hurricane Patricia
At 23:00 UTC, the cyclone made landfall at Cuixmala in the municipality of La Huerta, Jalisco—about 55 mi (85 km) west-northwest of Manzanillo—with winds of 150 mph (240 km/h) and an estimated pressure of 932 mbar (hPa; 27.49 inHg). This made Patricia the strongest hurricane to strike Mexico's Pacific coast, exceeding an unnamed storm in 1959 and Madeline in 1976 (the latter of which has not been reanalyzed). Although Patricia was operationally thought to have made landfall as a Category 5 hurricane with winds of 165 mph (270 km/h) and a pressure of 920 mbar (hPa; 27.17 inHg), reanalysis of available data suggested that the hurricane weakened more rapidly than originally thought: an automated station in Cuixmala measured a pressure of 934.2 mbar (hpa; 27.54 inHg), while storm chasers in Emiliano Zapata, just inside the eye of Patricia, measured a pressure of 937.8 mbar (hPa; 27.70 inHg). Their observations also indicated a pressure gradient of 11 mbar (hPa; 0.32 inHg) per nautical mile.
