The 2002 Pacific hurricane season was a near–average season which produced fifteen named storms. Eight hurricanes formed, including a record-equaling three Category 5 hurricanes, a record it shares with the 1994 and 2018 seasons. It was also a near-average season in terms of accumulated cyclone energy (ACE), having an ACE of 125. The season officially began on May 15, 2002 in the East Pacific Ocean, and on June 1, 2002 in the Central Pacific; both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclone formation occurs in these regions of the Pacific. The first system of the 2002 season, Hurricane Alma, formed on May 24, and the last, Tropical Depression Sixteen-E, dissipated on November 16.
The 1998 Pacific hurricane season was a fairly average Pacific hurricane season. Despite this, it had nine hurricanes and six major hurricanes, which was well above average. The season officially started on May 15 in the eastern Pacific and on June 1 in the central Pacific, and ended on November 30; these dates conventionally delimit the period during which most tropical cyclones form in that region. The first tropical cyclone developed on June 11, about ten days later than the normal start of the season. The final storm of the year, Hurricane Madeline, dissipated on October 20. Storm activity in the Central Pacific Hurricane Center's warning zone was low, with just one tropical depression observed in the region. Two tropical cyclones from the eastern Pacific also entered the central Pacific; the former did so as a hurricane.
The 1995 Pacific hurricane season was the least active Pacific hurricane season since 1979, and marked the beginning of a multi-decade period of low activity in the basin. Of the eleven tropical cyclones that formed during the season, four affected land, with the most notable storm of the season being Hurricane Ismael, which killed at least 116 people in Mexico. The strongest hurricane in the season was Hurricane Juliette, which reached peak winds of 150 mph (240 km/h), but did not significantly affect land. Hurricane Adolph was an early-season Category 4 hurricane. Hurricane Henriette brushed the Baja California Peninsula in early September.
The 1990 Pacific hurricane season was a very active season which observed 21 named storms within the basin. The season also produced the fourth highest ACE index value on record. The season was officially started on May 15 in the eastern Pacific, and on June 1 in the central Pacific, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. However, the formation of tropical cyclones is possible at any time of the year, as illustrated in 1990 by the formation of the season's first named storm, Hurricane Alma, on May 12. At the time, this was the earliest formation of a tropical storm on record in the eastern Pacific
Hurricane Juliette was a powerful Pacific hurricane that struck Mexico in September 2001. A long-lived tropical cyclone, Juliette originated from a tropical wave that exited western Africa, the same wave that earlier spawned Atlantic Tropical Depression Nine near Nicaragua on September 19. Two days later, a new tropical depression developed offshore Guatemala, which became Hurricane Juliette by September 22 as it rapidly intensified off western Mexico. On September 24 it strengthened into a Category 4 hurricane on the Saffir-Simpson scale, only to weaken due to an eyewall replacement cycle, then re-intensified a day later to attain maximum sustained winds of 230 km/h (145 mph), with a minimum barometric pressure of 923 mbar (27.3 inHg). Juliette weakened as it moved toward the Baja California peninsula, producing hurricane-force winds and torrential rainfall across Baja California Sur. On September 30 after the hurricane had weakened, Juliette made landfall near San Carlos as a minimal tropical storm. After drifting across the Gulf of California, Juliette dissipated on October 3.
Hurricane Javier was a powerful tropical cyclone whose remnants brought above-average rainfall totals across the western United States in September 2004. Javier was the tenth named storm, the sixth hurricane and the final major hurricane of the 2004 Pacific hurricane season. Javier was also the strongest hurricane of the 2004 season, with 150 mph (240 km/h) winds and a central pressure of 930 millibars. However, because of high wind shear in the East Pacific, Javier weakened rapidly before making landfall in Baja California as a tropical depression. The remnants of the storm then continued moving northeast through the Southwestern United States. Javier caused no direct fatalities, and the damage in Mexico and the United States was minimal.
Hurricane John was a Category 4 hurricane that caused heavy flooding and extensive damage across most of the Pacific coast of Mexico in late August through early September 2006. John was the eleventh named storm, seventh hurricane, and fifth major hurricane of the 2006 Pacific hurricane season. Hurricane John developed on August 28 from a tropical wave to the south of Mexico. Favorable conditions allowed the storm to intensify quickly, and it attained peak winds of 130 mph (210 km/h) on August 30. Eyewall replacement cycles and land interaction with western Mexico weakened the hurricane, and John made landfall on southeastern Baja California Sur with winds of 110 mph (180 km/h) on September 1. It slowly weakened as it moved northwestward through the Baja California peninsula, and dissipated on September 4. Moisture from the remnants of the storm entered the southwest United States.
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.
Tropical Storm Emilia was a rare tropical cyclone that affected the Baja California Peninsula in July 2006. The sixth tropical depression and fifth tropical storm of the 2006 Pacific hurricane season, it developed on July 21 about 400 miles (640 km) off the coast of Mexico. It moved northward toward the coast, reaching peak winds of 65 mph (105 km/h) before turning westward and encountering unfavorable conditions. Emilia later turned to the north, passing near Baja California as a strong tropical storm. Subsequently, the storm moved further away from the coast, and on July 27 it dissipated.
The 2008 Pacific hurricane season was a near-average Pacific hurricane season which featured seventeen named storms, though most were rather weak and short-lived. Only seven storms became hurricanes, of which two intensified into major hurricanes. This season was also the first since 1996 to have no cyclones cross into the central Pacific. The season officially began on May 15 in the eastern Pacific and on June 1 in the central Pacific. It ended in both regions on November 30. These dates, adopted by convention, historically describe the period in each year when most tropical cyclone formation occurs in these regions of the Pacific. This season, the first system, Tropical Storm Alma, formed on May 29, and the last, Tropical Storm Polo, dissipated on November 5.
Tropical Storm Norman was a weak tropical cyclone that brought heavy rainfall to southwestern Mexico in October 2006. The fifteenth named storm of the 2006 Pacific hurricane season, Norman developed on October 9 from a tropical wave well to the southwest of Mexico. Unfavorable conditions quickly encountered the system, and within two days of forming, Norman dissipated as its remnants turned to the east. Thunderstorms gradually increased again, as it interacted with a disturbance to its east, and on October 15 the cyclone regenerated just off the coast of Mexico. The center became disorganized and quickly dissipated, bringing a large area of moisture which dropped up to 6 inches (150 mm) of rainfall to southwestern Mexico. Rainfall from the storm flooded about 150 houses, of which 20 were destroyed. One person was injured, and initially there were reports of two people missing due to the storm; however, it was not later confirmed.
Tropical Storm Kiko was a strong tropical storm that capsized a boat off the western coast of Mexico, killing at least 15 people. The 15th and final tropical cyclone of the 2007 Pacific hurricane season, Kiko developed out of a tropical wave that formed off the coast of Africa on September 26 and traversed the Atlantic. The wave crossed over Central America and entered the Pacific Ocean on October 8, where it spawned Tropical Depression 15-E on October 15. The depression drifted to the south over the next day before briefly being declared Tropical Storm Kiko. It subsequently weakened into a tropical depression, but later reattained tropical storm intensity. By October 18, Kiko was forecast to make landfall along the western Mexican coastline as a moderate tropical storm. However, the cyclone turned to the west and reached its peak intensity of 70 mph (110 km/h) on October 20. The tropical storm slowly weakened to a remnant low-pressure area by October 24 and completely dissipated on October 27 without making landfall.
The 2006 Pacific hurricane season was the first above-average season since 1997 which produced twenty-five tropical cyclones, with nineteen named storms, though most were rather weak and short-lived. There were eleven hurricanes, of which six became major hurricanes. Following the inactivity of the previous seasons, forecasters predicted that season would be only slightly above active. It was also the first time since 2003 in which one cyclone of at least tropical storm intensity made landfall. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. However, the formation of tropical cyclones is possible at any time of the year.
The 2009 Pacific hurricane season was the most active Pacific hurricane season since 1997. 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 the Eastern Pacific tropical cyclone basin; however, tropical cyclone formation is possible at any time of the year. The first system of the season, Tropical Depression One-E, developed on June 18, and the last, Hurricane Neki, dissipated on October 27, keeping activity well within the bounds of the season.
Tropical Depression Five-E was a tropical depression which made landfall along the south-western Mexican coastline in July 2008. It was the fifth tropical cyclone of the 2008 Pacific hurricane season. The depression developed out of a weak tropical wave which formed off the coast of Africa on June 23. The wave remained poorly organized throughout its journey through the Atlantic Ocean and Caribbean Sea. The wave entered the Eastern Pacific on July 2 after passing through Central America. The wave developed into an area of low pressure 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.
Hurricane Howard was a powerful Category 4 hurricane which produced large swells along the coasts of the Baja California Peninsula and southern California. The cyclone was the eighth named storm, fourth hurricane, and second major hurricane of the 2004 Pacific hurricane season. Howard originated out of a tropical wave off the coast of Mexico on August 30. Traveling towards the northwest, the storm gradually strengthened, becoming a hurricane on September 1 and reaching its peak intensity the following day with winds of 140 mph (220 km/h). Decreasing sea surface temperatures then caused the storm to weaken. By September 4, Howard was downgraded to a tropical storm. The next day, it degenerated into a non-convective remnant low-pressure area which persisted for another five days before dissipating over open waters.
Tropical Storm Carlos was the first of five tropical cyclones to make landfall during the 2003 Pacific hurricane season. It formed on June 26 from a tropical wave to the south of Mexico. It quickly strengthened as it approached the coast, and early on June 27 Carlos moved ashore in Oaxaca with winds of 65 mph (105 km/h). The storm rapidly deteriorated to a remnant low, which persisted until dissipating on June 29. Carlos brought heavy rainfall to portions of southern Mexico, peaking at 337 mm (13.3 in) in two locations in Guerrero. Throughout its path, the storm damaged about 30,000 houses, with a monetary damage total of 86.7 million pesos. At least nine people were killed throughout the country, seven due to mudslides and two from river flooding; there was also a report of two missing fishermen.
Hurricane Frank was a Category 1 hurricane that caused minor damage in Mexico in late August 2010. The ninth tropical cyclone, sixth named storm, and third hurricane of the inactive 2010 Pacific hurricane season, Frank formed from an area of thunderstorms from the Caribbean Sea, and became Tropical Depression Nine-E on August 21 while located just south of the Mexican Coast. It moved northwest, and became Tropical Storm Frank only 12 hours after it was declared a depression. It strengthened to its initial peak as a moderate tropical storm, and weakened due to increasing wind shear late on the August 23. It later recovered, and became a hurricane on August 25. After peaking as a strong Category 1 hurricane, it rapidly weakened, and dissipated on August 28. Although Frank never made landfall, it did impact western Mexico. A total of six people were killed with over 800,000 people affected.
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.
