Hurricane Norbert is tied with Hurricane Jimena as the strongest tropical cyclone to strike the west coast of Baja California Sur in recorded history. The fifteenth named storm, seventh hurricane, and second major hurricane of the 2008 hurricane season, Norbert originated as a tropical depression from a tropical wave south of Acapulco on October 3. Strong wind shear initially prevented much development, but the cyclone encountered a more favorable environment as it moved westward. On October 5, the National Hurricane Center (NHC) upgraded the depression to Tropical Storm Norbert, and the system intensified further to attain hurricane intensity by October 6. After undergoing a period of rapid deepening, Norbert reached its peak intensity as a Category 4 on the Saffir–Simpson hurricane wind scale, with maximum sustained winds of 135 mph (217 km/h) and a minimum barometric pressure of 945 mbar (945 hPa; 27.9 inHg). As the cyclone rounded the western periphery of a subtropical ridge over Mexico, it began an eyewall replacement cycle which led to steady weakening. Completing this cycle and briefly reintensifying into a major hurricane, a Category 3 or higher on the Saffir–Simpson hurricane wind scale, Norbert moved ashore Baja California Sur as a Category 2 hurricane late on October 11. After a second landfall at a weaker intensity the following day, the system quickly weakened over land and dissipated that afternoon.
In preparation for the cyclone, the NHC issued hurricane warnings for coastal regions of the Baja California Peninsula. Residents living in low-lying areas and flood-prone regions were advised to evacuate, and beach-goers were warned to stay out of the water. Upon landfall, the hurricane produced waves in excess of 13 ft (4.0 m). Though the strongest winds observed were less than hurricane intensity, heavy rainfall as a result of Norbert lead to substantial damage. In Baja California Sur, roughly 5,000 homes sustained major damage; the heaviest-impacted municipality, Comondú, reported 16,000 homes affected. Thousands of people were forced into shelters, and many trees were blown down by strong winds. A total of 25 fatalities occurred in Sonora, five of which occurred in Álamos, where excessive rainfall caused a majority of the town to become flooded; homes were submerged to their roofs and many trees were downed. The hurricane severely impacted the fishing industry in Sinaloa, while thousands of residents were left homeless. In the United States, Norbert produced minimal rainfall. In the aftermath of the storm, many towns and municipalities were declared disaster areas. Overall, Norbert inflicted $98.5 million (2008 USD) in damage.
