Hurricane John was a powerful tropical cyclone that caused deadly flooding across southern Mexico for several days in September 2024. The eleventh named storm,fourth hurricane,and second major hurricane of the 2024 Pacific hurricane season,John originated from a low-pressure area offshore Southern Mexico. This low developed into Tropical Depression Ten‑E on the afternoon of September 22,strengthening into Tropical Storm John the following morning. Undergoing rapid intensification,John strengthened from a moderate tropical storm into a Category 3 hurricane on September 24. It was at that intensity that John made landfall in Marquelia,Guerrero,later that day. Once inland,John rapidly weakened,dissipating over Mexico later that day. However,the mid-level remnants of John moved back over the ocean,where favorable conditions enabled John to redevelop. On September 27,after again becoming a minimal hurricane,Tropical Storm John made its second landfall,this time near Tizupan,Michoacán. Hours later,it dissipated for a final time over the coastal mountains.
John resulted in strong winds,significant flooding,and numerous mudslides across much of coastal southwestern Mexico. A total of 950 mm (37 in) of rain fell across parts of Guerrero,with similarly extreme rainfall in neighboring Oaxaca and Michoacán. More than 98,000 people lost power in Oaxaca. As of September 28,twenty-nine deaths have been reported in association with John.
On September 21, an area of low pressure producing disorganized showers and thunderstorms formed off the coast of southern Mexico. [1] The system became better organized the following day and attained a closed surface circulation, resulting in the formation of Tropical Depression Ten‑E on the afternoon of September 22, about 175 mi (280 km) south of Punta Maldonado, Guerrero. [2] The system continued to develop that night, and strengthened into Tropical Storm John at 06:00 UTC the following morning. [3] While moving slowly to the north-northeast on September 23, caught in the southwesterly flow associated with the monsoon trough near Central America, [4] John commenced to rapidly intensify. It became a Category 1 hurricane at 17:45 UTC that same day, [5] and then, just nine hours later, reached Category 3 major hurricane intensity with sustained winds of 120 mph (195 km/h). [6] It was at that intensity that John made landfall in Marquelia, Guerrero, about 25 mi (40 km) northwest of Punta Maldonado, at 03:20 UTC on September 24. [7] John rapidly weakened inland, with its winds falling to tropical storm strength about 12 hours later. [8] By 18:00 UTC on September 24, John dissipated over the rugged terrain of southern Mexico. [9]
An elongated trough developed in association with John's remnants as the cyclone dissipated. [9] The trough produced a large area of shower and thunderstorm activity, and began showing signs of organization on September 25. [10] Ship observations indicated significant pressure falls within the system, and by 15:00 UTC, John reformed into a tropical storm. [11] [12] John moved slowly to the north-northwest after it reformed, and within favorable environmental conditions for strengthening, the storm steadily re-intensified. [13] Continuing its slow motion very close to the southwestern coast of Mexico, John developed a small, closed eye, and re-intensified to a minimal hurricane at 12:00 UTC on September 26. [14] [15] John continued to move very slowly near the coast, where its proximity to the rugged terrain of Mexico halted intensification; the cyclone weakened to a tropical storm at 3:00 UTC the following day. [16] After hugging the coast for nearly 36 hours and continuing to weaken, John finally made landfall on southwestern Mexico for the second time at 18:00 UTC on September 27. [17] John's surface center dissipated shortly thereafter, and the United States-based National Hurricane Center issued its final advisory on the storm three hours later. [18]

Upon the formation of John as a tropical cyclone on the afternoon of September 22, a Tropical Storm Watch was issued from Punta Maldonado to Salina Cruz, Oaxaca. [19] At 09:00 UTC the following day, this was changed to a Tropical Storm Warning from Punta Maldonado to Huatulco, with a Tropical Storm Watch extending to Salina Cruz. A Hurricane Watch was declared within the Tropical Storm Warning area. [20] The Hurricane Watch was upgraded to a Hurricane Warning a few hours later. [21] A red emergency alert was issued for Guerrero and Oaxaca. [22] John threatened parts of Mexico still recovering from Hurricane Otis the previous year, which underwent a similar rapid intensification phase. Tourists in Puerto Escondido, Oaxaca, were expected to be evacuated by the Secretariat of Civil Protection (SSPC). [23] Businesses across the city were closed. [24] The Puerto Escondido International Airport also closed for the duration of the storm. [25] More than 80 emergency shelters were prepared and 3,000 people were evacuated. [24] The Federal Electricity Commission (CFE) deployed over 1,400 electricians and several cranes and emergency power plants to respond to power outages in affected regions. [26] Schools were closed in Guerrero and Oaxaca. [22]

Over 250 mm (10 in) of rain fell across parts of Guerrero and Oaxaca within the first few hours after John's landfall. [37] Over 500 mm (20 in) of rain fell in Acapulco. [38] In total, John dropped 1,442 mm (56.8 in) of rain in Guerrero, five times the amount that fell during Otis's passage the previous year; 19 neighborhoods were left completely underwater, and over 2,000 homes were flooded. [39] [40] Some local regions along John's path received 80% of their typical yearly rainfall from the storm. [41] [42] Torrential rains also fell across the neighboring states of Chiapas, Veracruz, Michoacán and Puebla. [43] The amount of rain dropped by John was considered historic, bringing 214% more water than Hurricane Pauline, which devastated southern Mexico in 1997. [44]
At least 29 people died in the storm: 23 in Guerrero, 5 in Oaxaca, and 1 in Michoacán. [45] [46] Governor of Guerrero Evelyn Salgado reported two deaths caused by a landslide in the municipality of Tlacoachistlahuaca. [47] Additionally, a 70-year-old woman was killed in Malinaltepec when a landslide struck her house. [48] Areas along the southwestern Mexican coast experienced mudslides while tin roofs were blown off several houses. [49] At least 80 landslides occurred in Oaxaca, cutting off roads and communities in the state. [50] 13 restaurants collapsed in Acapulco. [45] The small village of El Espinalillo in southern Guerrero was completely cut off from electricity, potable water and communications outside the town. [41] The Mexican federal government's National Civil Protection Coordination rescued 5,120 people from flooded areas in Acapulco. [44]
The president of the Acapulco Chamber of Commerce, Services and Tourism, Alejandro Martínez Sidney, stated that losses from John in Guerrero were estimated to be between MXN$1–1.5 billion (US$50.8–76.3 million). [a] [51] According to insurance company Gallagher Re, total losses are estimated to be US$1 billion as of October 2024. [32] Following the storm, the Mexican Navy activated Plan DN-III-E, a disaster relief and rescue plan, with 25,000 military units deployed to assist residents affected by John. [39] At least 18,728 members of an international relief task force were sent to assist affected residents by the National Civil Protection Coordination. In the Costa Chica and Costa Grande regions, 5,000 people were placed in temporary storm shelters. [44] In Oaxaca, where over 98,000 people lost power, 18,000 armed services members and government workers were deployed to assist in emergency response operations. [37] The World Central Kitchen distributed over 878,000 meals to those impacted by the hurricane. [52] The Mexican federal government announced it would invest MXN$6.1 billion (US$305.9 million) [b] into caring for the 154,133 homes surveyed following the storm's passage. [53]
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.
The 2014 Pacific hurricane season was one of the busiest and costliest Pacific hurricane seasons since the keeping of reliable records began in 1949. The season officially started on May 15 in the East Pacific Ocean, 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 these regions of the Pacific.
The 2017 Pacific hurricane season was an above average Pacific hurricane season in terms of named storms, though less active than the previous three, featuring eighteen named storms, nine hurricanes, and four major hurricanes. Despite the considerable amount of activity, most of the storms were weak and short-lived. The season officially started on May 15 in the eastern Pacific Ocean, 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 respective regions. However, the formation of tropical cyclones is possible at any time of the year, as illustrated in 2017 by the formation of the season's first named storm, Tropical Storm Adrian, on May 9. At the time, this was the earliest formation of a tropical storm on record in the eastern Pacific basin proper. The season saw near-average activity in terms of accumulated cyclone energy (ACE), in stark contrast to the extremely active seasons in 2014, 2015, and 2016; and for the first time since 2012, no tropical cyclones formed in the Central Pacific basin. However, for the third year in a row, the season featured above-average activity in July, with the ACE value being the fifth highest for the month. Damage across the basin reached $375.28 million (2017 USD), while 45 people were killed by the various storms.
Hurricane Erick brought moderate impacts to the western coastline of Mexico in July 2013, and was the last of a succession of four Category 1 hurricanes to affect the Pacific coast of Mexico early in the 2013 Pacific hurricane season. The fifth named storm and fourth hurricane of the annual season, Erick originated from a tropical wave that moved off the western coast of Africa on June 18. The wave tracked swiftly westward with little development, emerging into the eastern Pacific on July 1. As a result of favorable environmental conditions, the wave developed into a tropical depression on July 4, and further into Tropical Storm Erick at 0000 UTC on July 5. Steered generally west-northwest, Erick intensified into a Category 1 hurricane and reached its peak intensity with winds of 80 mph (130 km/h) on July 6. Its proximity to land and track over increasingly cooler waters caused the storm to deteriorate into a tropical storm the following day, though it remained at such intensity until degenerating into a remnant low early on July 9. The remnant circulation dissipated a few hours later, southwest of Baja California Sur.
Hurricane Amanda was the strongest Eastern Pacific tropical cyclone ever recorded in the month of May. The first named storm, hurricane and major hurricane of the 2014 Pacific hurricane season, Amanda originated from a tropical wave that had entered the Eastern Pacific on May 16. Slow development occurred as it tracked westward, and development into a tropical depression occurred on May 22. The depression later strengthened into a tropical storm on May 23. Amid very favorable conditions, Amanda then rapidly intensified late on May 23, eventually reaching its peak intensity on May 25 as a high-end Category 4 hurricane. Afterwards, steady weakening occurred due to upwelling beneath the storm, and Amanda fell below major hurricane intensity on May 26. Rapid weakening occurred and the cyclone eventually dissipated on May 29.
Tropical Storm Trudy was a short-lived tropical cyclone in October 2014 that caused significant flooding in southern Mexico. The storm originated from an area of low pressure associated with a monsoon trough near Central America in early October. A slow-moving system, the low eventually consolidated into a tropical depression on October 17 near the Mexican coastline. Favorable environmental conditions aided rapid development of Trudy. Within 15 hours of its designation, an eye formed over the storm's center. Trudy ultimately achieved its peak intensity as a strong tropical storm with 65 mph (100 km/h) winds as it made landfall just southeast of Marquelia, Mexico. The region's mountainous terrain quickly weakened Trudy and the cyclone dissipated early on October 19. Though the cyclone dissipated, its remnant energy later contributed to the formation of Tropical Storm Hanna in the Atlantic.
Hurricane Carlos was an unusually small tropical cyclone which affected the western coast of Mexico in June 2015. Forming as the third named storm and hurricane of the annual hurricane season, Carlos developed from a trough first noted by the National Hurricane Center on June 7. The disturbance gradually organized and was designated as a tropical depression three days later while south of the Mexican Pacific coast. Drifting slowly northwestward, the depression was upgraded further to a tropical storm. Although persistent wind shear and dry air hampered intensification early on, Carlos strengthened into a hurricane on June 13 after moving into a more favorable environment. However, the return of dry air and upwelling of cooler waters caused the system to deteriorate into a tropical storm. Paralleling the Mexican coast, Carlos later regained hurricane intensity on June 15 and attained peak winds of 90 mph (140 km/h) a day later. The reprieve was brief, however, as the onset of wind shear, land interaction, and dry air afterward led to rapid weakening. On June 17, Carlos degenerated into a remnant area of low pressure, having made landfall in Jalisco earlier that day. By the morning of June 18, Carlos was declared to have completely dissipated.
Hurricane Marty was a tropical cyclone that produced heavy rains and flooding in several states in Southwestern and Western Mexico. The twentieth named storm and twelfth hurricane of the annual hurricane season, Marty developed from a tropical wave on September 26, 2015, to the southwest of Acapulco, Guerrero, in Mexico. Initially a tropical depression, the system strengthened into a tropical storm early on the following day. Due to favorable atmospheric conditions, Marty continued to intensify, but wind shear sharply increased as the storm approached a large mid- to upper-level trough. Despite this, the cyclone deepened further, becoming a hurricane on September 28 and peaking with sustained winds of 80 mph (130 km/h) shortly thereafter. Wind shear quickly took its toll on the hurricane, weakening it to a tropical storm early on September 29. About 24 hours later, Marty degenerated into a post-tropical low-pressure area offshore Guerrero. The low further degenerated into a trough later on September 30, and eventually dissipated on October 4.
Hurricane Max was a rapidly-forming tropical cyclone that made landfall in southwestern Mexico, causing minor damage. The sixteenth tropical cyclone, thirteenth named storm, and seventh hurricane of the 2017 Pacific hurricane season, Max developed from a trough of low pressure near the southwestern coast of Mexico on September 13. The storm tracked northeastward under the influence of a mid-level ridge and rapidly strengthened as a result of warm ocean temperatures in its path. Max strengthened into a hurricane on September 14 and peaked as a high-end Category 1 hurricane on the Saffir–Simpson scale shortly before making landfall in the Mexican state of Guerrero. Rapid weakening ensued as Max moved over the mountainous terrain of Mexico, and it weakened below hurricane strength early on September 15. At 12:00 UTC that day, Max dissipated over the mountains of southern Mexico.
The 2021 Pacific hurricane season was a moderately active Pacific hurricane season, with above-average activity in terms of number of named storms, but below-average activity in terms of major hurricanes, as 19 named storms, 8 hurricanes, and 2 major hurricanes formed in all. It also had a near-normal accumulated cyclone energy (ACE). The season officially began on May 15, 2021 in the Eastern Pacific Ocean, and on June 1, 2021, in the Central Pacific in the Northern Hemisphere. The season ended in both regions on November 30, 2021. These dates historically describe the period each year when most tropical cyclogenesis occurs in these regions of the Pacific and are adopted by convention. However, the formation of tropical cyclones is possible at any time of the year, as illustrated by the formation of Tropical Storm Andres on May 9, which was the earliest forming tropical storm on record in the Eastern Pacific. Conversely, 2021 was the second consecutive season in which no tropical cyclones formed in the Central Pacific.
The 2022 Pacific hurricane season was a slightly above average hurricane season in the eastern North Pacific basin, with nineteen named storms, ten hurricanes, and four major hurricanes. Two of the storms crossed into the basin from the Atlantic. In the central North Pacific basin, no tropical cyclones formed. The season officially began on May 15 in the eastern Pacific, and on June 1 in the central; both ended on November 30. These dates historically describe the period each year when most tropical cyclogenesis occurs in these regions of the Pacific and are adopted by convention.
Tropical Storm Ileana was a small tropical cyclone that affected western Mexico in early August 2018, causing deadly flooding. The eleventh tropical cyclone and ninth named storm of the 2018 Pacific hurricane season, Ileana originated from a tropical wave that the National Hurricane Center began monitoring on July 26 as the wave left the west coast of Africa. The wave traveled across the Atlantic Ocean with no thunderstorm activity, before crossing into the Eastern Pacific Ocean early on August 4. Rapidly developing, the disturbance organized into a tropical depression on the evening of the same day. Initially, the depression was well-defined, but it soon degraded due to northerly wind shear. Despite the unfavorable conditions, the system began to strengthen on August 5, becoming Tropical Storm Ileana. A day later, on August 6, Ileana began to develop an eyewall structure as it reached its peak intensity with winds of 65 mph (100 km/h) and a pressure of 998 mbar (29.47 inHg). The storm gradually became intertwined with the nearby Hurricane John; over the next day, the circulation of John disrupted Ileana before ultimately absorbing it on August 7.
Tropical Storm Narda was a short-lived tropical storm that remained close to the Pacific coast of Mexico, causing flash flooding and mudslides in southwestern Mexico and the Baja California Peninsula in late September 2019. The fourteenth named storm of the 2019 Pacific hurricane season, Narda developed from a broad area of low pressure that formed off the Central American Pacific coast on September 26. The broad low gradually organized as it moved west-northwestward, and it became Tropical Storm Narda early on September 29 while located off the southern coast of Mexico. The cyclone strengthened slightly before it moved inland near Manzanillo. Narda weakened to a tropical depression after moving inland, but restrengthened into a tropical storm on September 30 as it emerged over the Pacific Ocean just south of the Gulf of California. Narda quickly strengthened, and reached its peak intensity with winds of 50 mph (85 km/h) that day before making a second landfall along the northwestern coast of Mexico. The tropical cyclone weakened rapidly as it moved along the coastline, and it weakened to a tropical depression before dissipating just off the coast of Sonora on October 1.
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.
Tropical Storm Dolores was a strong tropical storm that made landfall in southwestern Mexico in June 2021. The fourth named storm of the 2021 Pacific hurricane season, Dolores developed from a low-pressure area that formed offshore the Mexican state of Oaxaca on June 16, 2021. The low steadily developed organized deep convection and a closed surface circulation, becoming Tropical Depression Four-E around 06:00 UTC June 18. The depression strengthened into a tropical storm nine hours later and was named Dolores. Gradually approaching the southwestern coast of Mexico, Dolores steadily intensified despite its close proximity to land. The storm reached its peak intensity around 15:00 UTC June 19 with maximum sustained winds of 115 km/h (70 mph) and a minimum barometric pressure of 29.2 inHg (989 mbar), just below hurricane strength. Shortly after reaching this intensity, Dolores made landfall just northwest of Punta San Telmo, near the Colima–Michoacán state border. The storm rapidly weakened as it moved inland over Mexico and dissipated early on June 20 over the state of Zacatecas.
Hurricane Nora was a large tropical cyclone that caused significant damage across the Pacific Coast of Mexico in late August 2021. The fourteenth named storm and fifth hurricane of the 2021 Pacific hurricane season, Nora was first monitored by the National Hurricane Center (NHC) as an area of low pressure near the coast of Mexico. On August 24, the low organized into tropical depression, but struggled to develop further due to wind shear in its surrounding environment. The depression eventually intensified into a tropical storm and was named Nora as it tracked to the west-northwest. Nora peaked as a strong Category 1 hurricane with maximum sustained winds of 85 miles per hour (140 km/h) on August 28. The storm then grazed the west coast of Mexico and made landfall two separate times, first in the state of Jalisco, followed by neighboring Nayarit. Nora weakened as it interacted with land, dissipating on August 30 just inland of the Mexican coast.
Hurricane Rick was a Category 2 Pacific hurricane that struck the southwestern coast of Mexico in late October 2021. Rick was the overall seventeenth named system and the eighth hurricane of the 2021 Pacific hurricane season, as well as the fifth named storm and fourth hurricane to make landfall along the Pacific coast of Mexico in 2021.
Hurricane Agatha was the strongest hurricane to make landfall along the Pacific coast of Mexico in the month of May since records began in 1949. The first named storm and the first hurricane of the 2022 Pacific hurricane season, Agatha originated from a surface trough south of the Gulf of Tehuantepec. It steadily organized into a tropical depression early on May 28 and within hours intensified into Tropical Storm Agatha. Amid favorable environmental conditions, the cyclone underwent rapid intensification on May 29, strengthening into a Category 2 hurricane and reaching peak winds of 110 mph (180 km/h). Though the storm moved west-northwest early on, it curved toward the northeast in response to weakening high pressure over Mexico. On the afternoon of May 30, the hurricane made landfall just west of Puerto Ángel, Oaxaca, with slightly weaker winds of 105 mph (169 km/h).
Hurricane Blas was a Category 1 hurricane that brought winds and flooding to several Mexican states in June 2022. The second named storm and second hurricane of the 2022 Pacific hurricane season, Blas developed from a low-pressure area off the coast of southwestern Mexico. It became a tropical depression on June 14. and strengthened into a tropical storm later that same day. Blas became a hurricane the next day, while paralleling the coast. The system reached its peak intensity on June 17, at 15:00 UTC, with maximum sustained winds of 80 knots and a central pressure of 976 mbar (28.82 inHg). Later, Blas turned to the west and weakened, becoming a tropical depression on June 20, before transitioning into a post-tropical cyclone on that same day.
