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 [a] 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 480 mm (19 in) 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). [b] 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).
A broad low-pressure area developed over the northeastern Pacific Ocean on October 15, 2023, producing a large area of disorganized showers and thunderstorms. With this convective activity gradually consolidating, the system organized into a tropical depression by 12:00 UTC on October 17 [c] about 400 nautical miles southwest of Manzanillo, Mexico. Six hours later, the depression strengthened into Tropical Storm Norma. Situated within an environment of warm sea-surface temperatures (SSTs), low vertical wind shear, and plentiful moisture, Norma underwent an almost two-day long period of rapid intensification shortly after forming, as a ridge over Mexico steered the system to the north while gradually slowing it down. At 18:00 UTC on October 18, 24 hours after being named, Norma strengthened into a hurricane. Just twelve hours later the storm achieved major hurricane status. Norma featured a well-defined, clear eye at this time.
The major hurricane continued to move slowly north, parallel to the west coast of Mexico, as it rounded the ridge. Norma reached its peak intensity as a Category 4 hurricane at 12:00 UTC on October 19, with maximum sustained winds of 210 km/h (130 mph) and a minimum barometric pressure of 939 mbar (27.7 inHg). The storm was centered 350 nautical miles south of Cabo San Lucas at the time. [1] After peaking in intensity, increased dry air and wind shear caused Norma's structure to degrade, and the storm weakened slightly as it turned northwestward and began to move more quickly. Norma fluctuated in intensity, achieving a secondary peak as a 195 km/h (120 mph) Category 3 hurricane on October 20. Despite this, increasingly cooler SSTs caused the hurricane to weaken rapidly as it turned north between the ridge over Mexico and a trough to its northwest. Norma made landfall on the Mexican state of Baja California Sur near 20:15 UTC on October 21 as a Category 1 hurricane, with maximum winds of 130 km/h (80 mph). Norma weakened to a tropical storm as it crossed the Baja California Peninsula, and emerged over the Gulf of California early the following day. Strong upper-level winds produced by the trough caused Norma's convective activity to be sheared away, and the storm weakened to a depression as it moved inland over the state of Sinaloa at 10:30 UTC on October 23. The cyclone dissipated over western Mexico by 18:00 UTC. [1]
Tropical storm and hurricane warnings were issued in advance of Norma’s landfalls, with the NHC anticipating rainfall totals of up to 460 mm (18 in) across portions of northwestern Mexico. [5] 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. [6] A total of 120 shelters were opened across Sinaloa. [7] Members of the Mexican Navy were deployed by Mexican President Andres Manuel Lopez Obrador to assist residents impacted by Norma. [8] The port of Puerto Vallarta was closed to small vessels as Norma passed offshore Jalisco. [9]
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 480 mm (19 in) in some areas. [10] Several wind gusts of over 145 km/h (90 mph) were recorded across the state, peaking at 170 km/h (107 mph) at a weather station on the outskirts of Cabo San Lucas. [11] 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. [6] [8] The port of La Paz was closed, leaving over 400 people stranded onboard a ferry crossing the Gulf of California from Sinaloa. [12] Downed utility poles in Cabo San Lucas disrupted electrical service to over 10,000 people. [13] In total, 109,209 electricity customers lost power during Norma's passage. [14] In San José del Cabo, 1,700 people were placed in 24 storm shelters. Two people were rescued after flood waters swept away their truck. [15] Three stores in La Paz suffered MXN$80–90 thousand (USD$4.6–5.2 thousand) worth of damage. [16] Total 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. [2] [17]
70,000 people were still left without power going into Monday, October 23. Schools remained closed in parts of the state into Monday as clean-up crews removed fallen trees and scattered debri across La Paz. [18] Some municipalities in the state were left without power a week after the storm, contradicting reports from the Federal Electricity Commission (CFE) that power had been fully restored by October 24. [19] Vandalism and looting also took place in various stores around Los Cabos. [20] 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; despite this, most hotels in the area suffered minimal damage from the hurricane. [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. [6] Peak accumulations of 300 mm (12 in) fell near where Norma's center came ashore. [10] Three people died in the state: two in vehicle-related accidents and a 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. [7] 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. [3] Almost 500 people were placed in storm shelters in the municipality of Guasave. Thirteen people were hospitalized due to a malfunctioning gasoline generator, though all were reported to be in stable condition. [22] Norma spread heavy rainfall over the neighboring states of Chihuahua, Durango, Sonora and Nayarit as it moved inland. [23]
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 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.
Hurricane Jimena is tied with Hurricane Norbert as the strongest tropical cyclone to make landfall on western portion of the Baja California Peninsula. Jimena was the twelfth named storm, fifth hurricane, third major hurricane and overall second-strongest tropical cyclone of the 2009 Pacific hurricane season. Forming from a tropical wave late on August 28, 2009, off of Mexico's Pacific coast, the system rapidly intensified into a Category 2 hurricane on the next day. Two days after developing, Jimena strengthened into a Category 4 hurricane. After peaking close to Category 5 intensity on September 1, it encountered cold water and began to weaken. When the hurricane made landfall on the Baja California Peninsula on September 3, it was only a Category 2 hurricane. On the next day, the tropical cyclone entered the Gulf of California, though the storm weakened into a remnant low after looping back eastward towards Baja California. The storm's remnants drifted westward into the Pacific afterward, before dissipating on September 8.
The 2013 Pacific hurricane season was an above average Pacific hurricane season with 21 tropical cyclones forming. Of these, 20 became named storms – 18 in the Eastern Pacific basin, and 2 in the Central Pacific basin. Of the 18 named storms in the east, 9 became hurricanes, with one, Raymond, becoming the season's only major hurricane. In the central, neither named storm became a hurricane. It was also a below-normal season in terms of Accumulated cyclone energy (ACE), as many of its systems were weak and short-lived. The season officially began on May 15 in the Eastern Pacific and started on June 1 in the Central Pacific; both ended on November 30. These dates conventionally delimit the period of each year when most tropical development occurs in these North Pacific basins. The first cyclone, Tropical Storm Alvin, formed on May 15, and the last, Tropical Storm Sonia, dissipated on November 4. It was below average only Category 3 storm was since 1981.
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 Sandra was the latest-forming major hurricane in the northeastern Pacific basin, the strongest Pacific hurricane on record in November, and the record eleventh major hurricane of the 2015 Pacific hurricane season. Originating from a tropical wave, Sandra was first classified as a tropical depression on November 23 well south of Mexico. Environmental conditions, including high sea surface temperatures and low wind shear, were highly conducive to intensification and the storm quickly organized. A small central dense overcast developed atop the storm and Sandra reached hurricane status early on November 25 after the consolidation of an eye. Sandra reached its peak intensity as a Category 4 hurricane on the Saffir–Simpson hurricane wind scale with winds of 150 mph (240 km/h) and a pressure of 934 mbar early on November 26. Thereafter, increasing shear degraded the hurricane's structure and weakening ensued. Rapid weakening took place on November 27 and Sandra's circulation became devoid of convection as it diminished to a tropical storm that evening. The cyclone degenerated into a remnant low soon thereafter and ultimately dissipated just off the coast of Sinaloa, Mexico, on November 29.
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 until it entered the Gulf of California, at which time 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.
The 2018 Pacific hurricane season was one of the most active Pacific hurricane seasons on record, producing the highest accumulated cyclone energy value on record in the basin. The season had the fourth-highest number of named storms – 23, tied with 1982. The season also featured eight landfalls, six of which occurred in Mexico. The season officially began on May 15 in the Eastern Pacific, and on June 1 in the Central Pacific; they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. However, tropical cyclone formation is possible at any time of the year, as illustrated when the first tropical depression formed on May 10, five days prior to the official start of the season.
Hurricane Bud was a tropical cyclone that brought winds and severe flooding to Mexico throughout its existence as a tropical cyclone in June 2018. It was the second named storm, hurricane, and major hurricane of the 2018 Pacific hurricane season. Bud originated from a tropical wave that departed from Western Africa on May 29. It traveled across the Atlantic Ocean before entering the Northeast Pacific Ocean late on June 6. The system moved towards the northwest and steadily organized, becoming a tropical depression on June 9 and Tropical Storm Bud early the next day. Favorable upper-level winds, ample moisture aloft, and warm sea surface temperatures allowed the storm to rapidly intensify to a hurricane late on June 10, and further to a major hurricane on the following day. Bud ultimately peaked the next morning with maximum sustained winds of 140 mph (230 km/h) and a minimum central pressure of 943 mbar. Its track curved more northward while the storm rapidly succumbed to the effects of upwelling. Bud made landfall on Baja California Sur as a minimal tropical storm early on June 15. On the next day, land interaction and increasing wind shear caused Bud to degenerate into a post-tropical cyclone. It opened up into a trough of low-pressure on June 16. The remnants of Bud moved towards the Southwestern United States, bringing tropical moisture and gusty winds to the region.
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, seventh 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 for the fourth consecutive season, 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.
