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, ranking it as the second deadliest Pacific hurricane on record, behind the 1959 Mexico Hurricane. 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 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 Lowell was a moderate tropical storm that developed during the 2008 Pacific hurricane season. The fourteenth tropical cyclone and thirteen named storm of the season, Lowell formed out of a western side of a trough on September 6. It quickly intensified into Tropical Storm Lowell, peaking as a moderate tropical storm. It pass directly over Socorro Island and began a weakening trend. It weakened into depression before landfall in Baja California Sur and dissipated before striking Sonora. It later joined with a frontal boundary and Hurricane Ike which caused severe damage as far inland as Chicago. In all, the storm had caused 6 deaths and $15.5 million damage.
Tropical Depression One-E was the earliest tropical cyclone in the calendar year to impact the Mexican state of Sinaloa ever recorded. The first system of the 2009 Pacific hurricane season, One-E formed out of an area of disturbed weather on June 18, 2009, and initially tracked slowly northwards. Throughout the day, convection developed around the center of circulation and the system was anticipated to become a tropical storm. Late on June 18, the National Hurricane Center noted that the system was on the verge of becoming a tropical storm; it would have been named Andres had this occurred. However, the following day, strong wind shear caused the depression to rapidly degenerate into a trough of low pressure before dissipating off the coast of Sinaloa.
Tropical Storm Patricia was a short-lived tropical cyclone that briefly affected parts of Baja California Sur before rapidly degenerating over water. Developing from a tropical wave that traversed the Atlantic Ocean during September 2009, Patricia was first classified as a tropical depression on October 11 several hundred miles south of the Baja California Peninsula. The system quickly intensified into a tropical storm as it tracked in a general northward direction. By October 12, Patricia attained its peak intensity with winds of 60 mph (95 km/h) and a minimum barometric pressure of 996 mbar. The following day, increasing wind shear and unfavorable conditions caused the storm to rapidly weaken. By the morning of October 14, Patricia had degenerated into a non-convective remnant low near the southern coastline of Baja California Sur. The remnants of the storm persisted until October 15, at which time they dissipated over open waters.
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.
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 Erick brought minor 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 Cosme caused flooding along the Pacific coast of Mexico in June 2013. The third named tropical cyclone of the 2013 Pacific hurricane season, the storm system formed from a tropical wave south of Manzanillo, Colima, on June 23. The cyclone intensified into a tropical storm on June 24, and soon after strengthened into a hurricane on June 25. Early the following day, Cosme attained its peak intensity as a Category 1 hurricane on the Saffir–Simpson scale with maximum sustained winds of 85 mph (140 km/h) and a minimum barometric pressure of 980 mbar. However, Cosme then began to encounter stable air and lower sea surface temperatures, causing the system to weaken to a tropical storm late on June 26. The system continued to weaken and degenerated into a remnant low pressure surface trough about 690 mi (1,110 km) west-southwest of Cabo San Lucas, Mexico, on June 27. The remnants persisted until dissipating well east-southeast of the Hawaiian Islands on July 1.
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 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.
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 Category 4 hurricane 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.
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.
Tropical Storm Hernan was a short-lived tropical cyclone that brought widespread flooding and destructive mudslides to southwestern Mexico in late August 2020. Hernan was the thirteenth tropical cyclone and eighth named storm of the 2020 Pacific hurricane season. The system developed from a low-pressure area to the southwest of Mexico on August 26, as a low-end tropical storm. Moving generally northward and paralleling the west coast of Mexico, Hernan was hindered by a high wind shear environment and only slightly strengthened. The cyclone achieved its peak intensity around 06:00 UTC on August 27 with maximum sustained winds of 70 km/h (45 mph) and a minimum barometric pressure of 1,001 mbar (29.6 inHg). Passing just offshore of the state of Jalisco, Hernan turned west and degenerated to a remnant low on August 28. The low passed near the southern tip of the Baja California Peninsula later that day and dissipated shortly thereafter.
Tropical Storm Ivo was a tropical cyclone that brought heavy rainfall to five states in Mexico, causing severe flooding during August 2019. The tenth tropical cyclone and ninth named storm of the 2019 Pacific hurricane season, Ivo arose from a low-pressure area that spawned south of Guatemala on August 16. The low-pressure system gradually organized over the next several days as it tracked west-northwestward. The system coalesced into a tropical depression early on August 21 and strengthened into Tropical Storm Ivo several hours later. Located within a favorable environment of moist air and warm sea surface temperatures, the cyclone quickly intensified, peaking the next day with 1-minute maximum sustained winds of 70 mph (110 km/h) and a pressure of 990 mbar (29.23 inHg). Increasing wind shear caused the storm's intensification to level off later that day, as the system turned towards the north-northwest. Ivo passed by Clarion Island midday on August 23, generating winds of 60 mph (100 km/h) on the island. Wind shear caused Ivo to significantly degrade in structure and intensity during the next couple of days. Cold sea surface temperatures, as well as dry and stable air, caused the cyclone to degenerate into a remnant low early on August 25. The low meandered over the eastern Pacific before opening up into a trough of low pressure early on August 27.
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 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.
Hurricane Pamela was a Category 1 Pacific hurricane that caused significant damage across several northwestern and western states of Mexico in October 2021. The sixteenth named storm and seventh hurricane of the 2021 Pacific hurricane season, the storm originated from a tropical wave over the Atlantic basin, over the Caribbean Sea. It then quickly crossed into the Pacific Ocean, where it slowly consolidated, with a low-pressure area forming from the wave on October 9. Environmental conditions in the area were proved favorable for tropical cyclogenesis and developed into Tropical Depression Sixteen-E on the next day. It then organized further into Tropical Storm Pamela on that night. Despite wind shear and dry air affecting the cyclone, Pamela continued to strengthen and became a hurricane on October 12 before weakening back to a tropical storm as it continued to succumb onto these factors. However, as the system turned towards the coast of Mexico, Pamela restrengthened to a low-end hurricane before making landfall over Estacion Dimas, Sinaloa on 15:00 UTC on October 13 before rapidly weakening inland. It then dissipated over Coahuila on the early hours on the next day.
Hurricane Orlene was a powerful tropical cyclone that caused minor damage to the Pacific coast of Mexico in October 2022. The cyclone was the sixteenth named storm, ninth hurricane, and third major hurricane of the 2022 Pacific hurricane season. Orlene originated from a low-pressure area off the coast of Mexico. Moving towards the north, Orlene gradually strengthened, becoming a hurricane on October 1 and reaching its peak intensity the following day with winds of 130 mph (215 km/h). Orlene made landfall just north of the Nayarit and Sinaloa border, with winds of 85 mph (140 km/h). Soon afterward, Orlene rapidly weakened and became a tropical depression, eventually dissipating over the Sierra Madre Occidental late on October 4.
