Hurricane Norma was one of four tropical cyclones to strike the Pacific Coast of Mexico in October 2023. The seventeenth tropical depression,fourteenth named storm,ninth hurricane and seventh major hurricane [lower-alpha 1] of the 2023 Pacific hurricane season,Norma developed from an area of low pressure that formed off the coast of southern Mexico on October 15,2023. The disturbance gradually organized as it progressed westward parallel to the coast,and developed into Tropical Storm Norma on October 17. Turning northward,Norma rapidly intensified to a Category 4 hurricane as it continued to parallel the west coast of Mexico. Less favorable environmental conditions caused Norma to gradually weaken as it approached the Baja California peninsula. The cyclone made landfall on the Mexican state of Baja California Sur as a Category 1 hurricane. Norma continued to weaken as it crossed the state. The storm emerged over the Gulf of California on October 22,and made landfall as a tropical depression the following day on the state of Sinaloa. Norma quickly dissipated as it moved inland over Mexico.
Norma resulted in extensive flooding across northwestern Mexico,peaking at nearly 19 in (480 mm) in parts of Baja California Sur. Numerous trees,homes and boats were damaged in the cities of Cabo San Lucas and La Paz. Damage across the state reached MXN$200 million (USD$11.1 million). [lower-alpha 2] Norma resulted in three fatalities in Sinaloa,as well as severe damage to numerous houses and businesses. Infrastructural damage alone in Sinaloa cost MXN$220.5 million (USD$12.2 million).
An area of low pressure formed south of the southern coast of Mexico on October 15, producing disorganized showers and thunderstorms. [2] The showers and thunderstorms associated with the disturbance gradually became better organized as it moved parallel with the southwestern coast of Mexico, and by the afternoon of October 17, had developed enough to be classified as Tropical Storm Norma. [3] Norma quickly intensified, and by the following morning was generating intense inner-core convection. Consequently, a ring of very cold cloud tops had formed around its center, within which a ragged eye had emerged. [4] Norma then rapidly intensified from a high-end tropical storm to Category 4 hurricane by the next morning. During the 24‑hour period ending 15:00 UTC on October 19, its maximum sustained winds rose from 70 mph (115 km/h) to 130 mph (210 km/h). [5] Later, moderate wind shear caused the system to weaken below major hurricane strength as it approached the southern end of the Baja California peninsula on the morning of October 21. [6] Shortly after 20:00 UTC that afternoon, the storm made landfall with sustained winds of 80 mph (130 km/h) about 15 mi (25 km) west-northwest of Cabo San Lucas. [7] Later, after moving offshore over the Gulf of California, strong wind shear enabled dry mid-level air to penetrate the circulation from the northwest, weakening the system to a tropical depression as it approached the coast of Sinaloa. [8] The system made its final landfall at about 16:30 UTC on October 23, near El Dorado, Sinaloa, and soon degenerated into a remnant low. [9]
Tropical storm and hurricane warnings were issued in advance of Norma’s landfalls, with the NHC anticipating rainfall totals of up to 18 in (460 mm) across portions of northwestern Mexico. [10] Schools were closed across the states of Baja California Sur and Sinaloa. Los Cabos International Airport and La Paz International Airport were also shut down in advance of the storm. [11] A total of 120 shelters were opened across Sinaloa. [12] Members of the Mexican Navy were deployed by Mexican President Andres Manuel Lopez Obrador to assist residents impacted by Norma. [13]
Torrential rainfall and strong winds affected Baja California Sur as Norma passed through the state. The intense rainfall led to extreme flooding, with peak accumulations of nearly 19 in (480 mm) in some areas. [14] Several wind gusts of over 90 mph (145 km/h) were recorded across the state, peaking at 107 mph (170 km/h) at a weather station on the outskirts of Cabo San Lucas. [15] Numerous streets and canals across La Paz flooded as Norma passed through Baja California Sur. Strong winds from Norma blew down numerous trees and palapas. Additionally, many sailboats and yachts were damaged in their piers along the city's coast. [11] [13] The port of La Paz was closed, leaving over 400 people stranded onboard a ferry crossing the Gulf of California from Sinaloa. [16] Downed utility poles in Cabo San Lucas disrupted electrical service to over 10,000 people. [17] A disaster declaration was issued by the governor of Baja California Sur, Víctor Manuel Castro Cosío, due to the extensive damage Norma wrought to public infrastructure in southern regions of the state. [18] Three stores in La Paz suffered MXN$80–90 thousand (USD$4.6–5.2 thousand) worth of damage. [19]
Infrastructural damage across Baja California Sur reached MXN$200 million (USD$11.1 million), according to Governor Castro. The governor also stated that he was not anticipating financial assistance from the Mexican federal government to cover the cost of damage produced by Norma. [20] [21]
Norma dumped heavy rainfall and caused widespread power outages across southern areas of Sinaloa as it made landfall on the state as a tropical depression. [11] Peak accumulations of 12 in (300 mm) fell near where Norma's center came ashore. [14] Three people died in the state, including two in vehicle-related accidents and a 3-year-old child due to electrocution. Broken glass, fallen trees and damage to homes and business was reported, mainly in the municipalities of Los Mochis, Ahome and Guasave. [12] The hurricane caused infrastructural damages totaling MXN$220.5 million (USD$12.2 million) across Sinaloa, damaging several roads and four bridges, as well as causing eighteen sinkholes to form across thirteen municipalities. [22]
The 1981 Pacific hurricane season was a slightly below average Pacific hurricane season. The season officially started on May 15 in the eastern Pacific basin and June 1 in the central Pacific basin. Both basins' seasons ended on November 30; these dates conventionally delimit the period during which most tropical cyclones form in the northeastern Pacific Ocean. The first tropical cyclone of the season was designated on May 30, and the final storm of the season, Hurricane Otis, dissipated on October 30. The season produced fifteen named storms and a total of eight hurricanes, which was near normal. However, the total of one major hurricane was below the average of three.
Hurricane Paul was a particularly deadly and destructive Pacific hurricane which killed a total of 1,625 people and caused US$520 million in damage. The sixteenth named storm and tenth hurricane of the 1982 Pacific hurricane season, Paul developed as a tropical depression just offshore Central America on September 18. The depression briefly moved inland two days later just before heading westward out to sea. The storm changed little in strength for several days until September 25, when it slowly intensified into a tropical storm. Two days later, Paul attained hurricane status, and further strengthened to Category 2 intensity after turning northward. The hurricane then accelerated toward the northeast, reaching peak winds of 110 mph (175 km/h). Paul made landfall over Baja California Sur on September 29, and subsequently moved ashore in Sinaloa the next day.
Hurricane Marty was a Category 2 Pacific hurricane that caused extensive flooding and damage in northwestern Mexico just weeks after Hurricane Ignacio took a similar course. Marty was the thirteenth named storm, fourth hurricane, and the deadliest tropical cyclone of the 2003 Pacific hurricane season. Forming on September 18, it became the 13th tropical storm and fourth hurricane of the year. The storm moved generally northwestward and steadily intensified despite only a marginally favorable environment for development, and became a Category 2 hurricane before making two landfalls on the Baja California peninsula and mainland Mexico.
Hurricane Paul was a Category 2 Pacific hurricane that struck Mexico as a tropical depression in October 2006. The seventeenth named storm and tenth hurricane of the annual hurricane season, Paul developed from an area of disturbed weather on October 21. The cyclone slowly intensified as it moved into an area of warm waters and progressively decreasing wind shear. Paul attained hurricane status on October 23, and later that day the storm reached its peak intensity with maximum sustained winds of 105 mph (169 km/h), a strong Category 2 hurricane on the Saffir-Simpson scale. A strong trough turned the hurricane to the north and northeast into an area of strong vertical shear, and Paul weakened to a tropical storm on October 24. It accelerated northeastward, and after passing a short distance south of Baja California Sur the low level circulation became decoupled from the rest of the convection. Paul weakened to a tropical depression on October 25 a short distance off the coast of Mexico, and after briefly turning away from the coast it made landfall on northwestern Sinaloa on October 26. The depression dissipated shortly thereafter.
Hurricane Ignacio was the latest-forming first hurricane of a Pacific hurricane season since reliable satellite observation began in 1966. The ninth tropical storm of the 2003 Pacific hurricane season, Ignacio developed out of a tropical wave on August 22 a short distance off the coast of Mexico. It was initially predicted to track out to sea and remain a weak tropical storm, though it unexpectedly organized rapidly to attain peak winds of 105 mph (169 km/h) on August 24 while located a short distance southeast of southern Baja California Sur. Land interaction weakened Ignacio to an 80 mph (130 km/h) hurricane by the time it made landfall near La Paz, and it dissipated on August 27 in the central Baja California peninsula.
Hurricane Isis was the only hurricane to make landfall during the 1998 Pacific hurricane season. The ninth tropical storm and sixth hurricane of the season, Isis developed on September 1 from an interaction between a tropical wave and a large surface circulation to the southwest of Mexico. It moved northward, striking the extreme southeastern portion of the Baja California peninsula before attaining hurricane status in the Gulf of California. Isis made landfall at Topolobampo in the Mexican state of Sinaloa on September 3, and quickly lost its low-level circulation. The remnants persisted for several days before dissipating over the U.S. state of Idaho on September 8.
Hurricane Lester was the first Pacific tropical cyclone to enter the United States as a tropical storm since 1967. The fourteenth named storm and eighth hurricane of the 1992 Pacific hurricane season, Lester formed on August 20 from a tropical wave southwest of Mexico. The tropical storm moved generally northwestward while steadily intensifying. After turning to the north, approaching the Mexican coast, Lester attained hurricane status. The hurricane reached peak winds of 85 mph (137 km/h) before making landfall on west-central Baja California. The system weakened while moving across the peninsula and then over northwestern Mexico. Not long after entering Arizona, Lester weakened to a tropical depression, and degenerated into an extratropical low on August 24, 1992, over New Mexico. The storm's remnants later merged with the remnants of Hurricane Andrew and another frontal system on August 29.
Hurricane Fausto was a Pacific hurricane that caused light damage to Baja California Sur in September 1996. On September 10, a tropical depression developed a short distance south-southeast of the Mexican Riviera. Slowly intensifying, Fuasto paralleled the coastline. It became a hurricane on September 12, and after briefly reaching major hurricane intensity, increasing wind shear resulted in a weakening trend. It traversed Baja California Sur on September 13 as minimal hurricane, and struck Sinaloa the next day. Inland, it degenerated into a remnant circulation by September 15. Fausto's remnants continued moving eastward across the Gulf of Mexico and later emerged into the Atlantic, before developing into a large nor'easter on September 17. Afterward, the system moved northeastward, before it was last noted on September 18.
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. 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.
Tropical Storm Norman was the fourteenth tropical cyclone of the 2012 Pacific hurricane season that brought minor flooding to western Mexico and record rainfall to areas of Texas in September 2012. Originating from a disturbance near the southern tip of Baja California, it soon moved north and developed into a tropical cyclone on September 28. Upon developing into one, Norman attained its peak intensity with maximum sustained winds of 50 mph (85 km/h). Heading northward into the Gulf of California, the storm began to weaken later that day due to southwesterly wind shear and land interaction. Norman curved northwestward and weakened to a tropical depression early on September 29. Around that time, it briefly moved inland near Topolobampo, Sinaloa, before re-emerging into the Gulf of California. Later on September 29, Norman degenerated into a remnant low pressure area.
Hurricane Paul was a strong tropical cyclone that threatened the Baja California peninsula during October 2012. The sixteenth tropical cyclone, tenth hurricane, and fifth major hurricane of the season, Paul originated from a trough of low pressure west of the coastline of Mexico on October 13. While turning towards the north, the system quickly organized, reaching hurricane status in the morning of October 15. By that afternoon, Paul had reached its peak intensity as a Category 3 hurricane on the Saffir-Simpson hurricane wind scale (SSHWS) with maximum sustained winds of 120 mph (195 km/h), but began to weaken rapidly thereafter due to land interaction and strong wind shear. Late on October 17, Paul degenerated into a remnant low. The remnants of Paul later moved ashore along the central Baja California Peninsula, before dissipating on October 18.
Hurricane Odile is tied for the most intense landfalling tropical cyclone in the Baja California Peninsula during the satellite era. Sweeping across the peninsula in September 2014, Odile inflicted widespread damage, particularly in the state of Baja California Sur, in addition to causing lesser impacts on the Mexican mainland and Southwestern United States. The precursor to Odile developed into a tropical depression south of Mexico on September 10 and quickly reached tropical storm strength. After meandering for several days, Odile began to track northwestward, intensifying to hurricane status before rapidly reaching its Category 4 hurricane peak intensity on September 14. The cyclone slightly weakened before making landfall near Cabo San Lucas with winds of 125 mph (205 km/h). Odile gradually weakened as it tracked across the length of the Baja California Peninsula, briefly crossing into the Gulf of California before degenerating into a remnant system on September 17. These remnants tracked northeastward across the Southwestern United States before they were no longer identifiable on September 19.
Hurricane Blanca in 2015 was the earliest recorded tropical cyclone in the calendar year to make landfall on the Baja California Peninsula. Forming as a tropical depression on May 31, Blanca initially struggled to organize due to strong wind shear. However, once this abated, the system took advantage of high sea surface temperatures and ample moisture. After becoming a tropical storm on June 1, Blanca rapidly intensified on June 2–3, becoming a powerful Category 4 hurricane on the Saffir–Simpson hurricane wind scale; maximum sustained winds reached 145 mph (230 km/h) at this time. The hurricane's slow motion resulted in tremendous upwelling of cooler water, resulting in a period of weakening. Blanca gradually recovered from this and briefly regained Category 4 status on June 6 as it moved generally northwest toward the Baja California peninsula. Cooler waters and increased shear again prompted weakening on June 7 and the system struck Baja California Sur on June 8 as a weak tropical storm. It quickly degraded to a depression and dissipated early the next day.
Hurricane Newton was the first tropical cyclone to make landfall on the Baja California Peninsula at hurricane strength since Hurricane Odile in 2014. The fifteenth tropical depression, fifteenth named storm and ninth hurricane of the 2016 Pacific hurricane season, Newton formed from a tropical wave to the south of Mexico on September 4, 2016. Moving northwards through an environment conducive for additional development, Newton rapidly strengthened, reaching hurricane strength on the following day. Newton made landfall on the Baja California Peninsula just below peak strength on the same day. Interaction with the mountainous terrain of the peninsula caused some slight weakening, but Newton remained a hurricane till it entered the Gulf of California. Increasing wind shear caused Newton to weaken at a faster pace, and the system made landfall in Sonora late on September 6 as a strong tropical storm. The cyclone continued to rapidly weaken over the rugged terrain of Sonora, and it degenerated into a remnant low just south of the Mexico–United States border on September 7. The remnants of Newton dissipated early on the following day.
Tropical Storm Lidia was a large tropical cyclone that caused flooding in Baja California Peninsula and parts of western Mexico. The fourteenth tropical cyclone and twelfth named storm of the 2017 Pacific hurricane season, Lidia developed from a large area of disturbed weather west of the Pacific Coast of Mexico on August 31. The storm intensified while moving generally northward or northwestward, peaking with maximum sustained winds of 65 mph (105 km/h) later that day. On September 1, Lidia made landfall in Mexico near Puerto Chale, Baja California Sur, at peak intensity. The storm weakened while traversing the peninsula, ultimately emerging over the Pacific Ocean on September 3, where the storm degenerated into a remnant low. The system brought thunderstorms and wind gusts to Southern California, before dissipating on September 4.
Hurricane Lorena was a strong Pacific hurricane in September 2019 that brought heavy rainfall, flooding, and mudslides to Southwestern Mexico and the Baja California Peninsula and also brought severe weather to the U.S. state of Arizona. Lorena was the thirteenth named storm and seventh and final hurricane of the 2019 Pacific hurricane season. A tropical wave, originally from the North Atlantic, entered the East Pacific basin on September 16. With increasing thunderstorm development, Lorena formed as a tropical storm on September 17 alongside Tropical Storm Mario. Lorena made its passage northwestward and quickly gained strength before it made landfall as a Category 1 hurricane in Jalisco on September 19. Due to interaction with the mountainous terrain, Lorena weakened back to a tropical storm. After moving into the warm ocean temperatures of the Gulf of California, however, Lorena re-strengthened into a hurricane, and reached its peak intensity with 1-minute sustained winds of 85 mph (137 km/h) and a minimum barometric pressure of 985 millibars (29.1 inHg) Lorena made a second landfall in the Mexican state of Baja California Sur, and quickly weakened thereafter. Lorena weakened to a tropical storm over the Gulf of California, and became a remnant low on September 22, shortly after making landfall in Sonora as a tropical depression. The remnant low moved inland over Mexico, and eventually dissipated inland over Arizona on September 24.
Hurricane Genevieve was a strong tropical cyclone that almost made landfall on the Baja California Peninsula in August 2020. Genevieve was the twelfth tropical cyclone, eighth named storm, third hurricane, and second major hurricane of the 2020 Pacific hurricane season. The cyclone formed from a tropical wave that the National Hurricane Center (NHC) first started monitoring on August 10. The wave merged with a trough of low pressure on August 13, and favorable conditions allowed the wave to intensify into Tropical Depression Twelve-E at 15:00 UTC. Just six hours later, the depression became a tropical storm and was given the name Genevieve. Genevieve quickly became a hurricane by August 17, and Genevieve began explosive intensification the next day. By 12:00 UTC on August 18, Genevieve reached its peak intensity as a Category 4 hurricane, with maximum 1-minute sustained winds of 130 mph and a minimum central pressure of 950 millibars (28 inHg). Genevieve began to weaken on the next day, possibly due to cooler waters caused by Hurricane Elida earlier that month. Genevieve weakened below tropical storm status around 18:00 UTC on August 20, as it passed close to Baja California Sur. Soon afterward, Genevieve began to lose its deep convection and became a post-tropical cyclone by 21:00 UTC on August 21, eventually dissipating off the coast of Southern California late on August 24.
The 2023 Pacific hurricane season was an active and destructive Pacific hurricane season. In the Eastern Pacific basin, 17 named storms formed; 10 of those became hurricanes, of which 8 strengthened into major hurricanes – double the seasonal average. In the Central Pacific basin, no tropical cyclones formed, though four entered into the basin from the east. Collectively, the season had an above-normal accumulated cyclone energy (ACE) value of approximately 168 units. This season saw the return of El Niño and its associated warmer sea surface temperatures in the basin, which fueled the rapid intensification of several powerful storms. It officially began on May 15, 2023 in the Eastern Pacific, and on June 1 in the Central; both ended on November 30. These dates, adopted by convention, historically describe the period in each year when most tropical cyclogenesis occurs in these regions of the Pacific.
Hurricane Olaf was a Category 2 Pacific hurricane that struck the Baja California Peninsula in September 2021. The fifteenth named storm and sixth hurricane of the 2021 Pacific hurricane season, the cyclone formed from an area of low pressure that developed off the southwestern coast of Mexico on September 5, 2021. The disturbance developed within a favorable environment, acquiring more convection and a closed surface circulation. The disturbance developed into Tropical Depression Fifteen-E by 18:00 UTC on September 7. The depression strengthened into a tropical storm and was named Olaf at 12:00 UTC the next day. Olaf quickly strengthened as it moved to the north-northwest, and was upgraded to a hurricane 24 hours after being named. Hurricane Olaf continued to intensify and reached peak intensity while its center was just offshore the southwestern coast of Baja California Sur, with maximum sustained winds of 105 mph (169 km/h) and a minimum barometric pressure of 975 mbar (28.8 inHg). Just after reaching peak intensity, the hurricane made landfall near San José del Cabo. Interaction with the mountainous terrain of the Baja California Peninsula caused Olaf to quickly weaken. It was downgraded to a tropical storm at 12:00 UTC on September 10. The system became devoid of convection later that day and degenerated to a remnant low by 06:00 UTC on September 11.
