Hurricane Hanna was the first of a record-tying six Atlantic hurricanes to make landfall in the United States in one year. The eighth named storm and first hurricane of the extremely active 2020 Atlantic hurricane season,Hanna developed from a tropical wave originating near Hispaniola. This disturbance dropped heavy rain upon parts of Hispaniola,Cuba,and Florida. The wave gradually became more organized and developed into a tropical depression in the central portion of the Gulf of Mexico. The depression strengthened into a tropical storm on July 24,setting a new record for the earliest eighth-named storm in the basin,getting its name 10 calendar days before the previous record holder,Tropical Storm Harvey of 2005. Hanna steadily intensified as it drifted toward Southern Texas,becoming the season's first hurricane early on July 25. It then began to quickly strengthen just before making landfall at 22:00 UTC later that day as a high-end Category 1 hurricane,with maximum sustained winds of 90 mph (140 km/h) and a minimum central pressure of 973 mbar (hPa;28.73 inHg). Hanna weakened quickly as it moved inland and turned west-southwest,eventually dissipating over Mexico on July 26.
In Florida,the precursor to Hanna killed one person due to rip currents. Hanna's outer bands also caused rounds of thunderstorms across parts of the Northern Gulf Coast. Along the way,it dumped up to 18 inches (460 mm) of rain in isolated areas in Southern Texas and Mexico. The storm resulted in 50,000+ people losing power.[ citation needed ] Hurricane Hanna caused minor damage to well-built structures,serious damage to smaller structures,and downed powerlines. In Texas,where the storm made landfall,extensive property damage was reported in the Rio Grande Valley especially in Port Mansfield. The brunt of the damage was located south of Corpus Christi due to the eye taking a more southward path than originally forecast. Corpus Christi experienced storm surge flooding and tropical storm-force winds,while areas south of the city experienced hurricane-force sustained winds,and in Mexico,severe flooding caused by Hanna killed four people. Overall,Hurricane Hanna was estimated to have caused a total of at least $1.2 billion in damage. [1]
A tropical wave moved off the west coast of Africa late on July 11. The convection that accompanied the wave was quickly choked off by dry mid-level air. The system continued westward within these same conditions without developing for several days. As it passed north of the Virgin Islands and Puerto Rico on July 18, minimal, but consistent shallow convection began to build on the northern side of the wave and the NHC began to monitor it for possible development early the next morning. [2] [3] The wave slowed and deep convection increased across its axis as it moved through Greater Antilles and the Southern Bahamas, although unfavorable upper-level winds kept it from organizing. However, after entering the southeastern Gulf of Mexico during the afternoon of July 21, the upper-level winds relaxed over the wave, which then started to gradually become better organized and more defined, with a broad area of low pressure forming on July 22. [4] During the morning hours of July 23, hurricane reconnaissance aircraft flew into the system, and was able to find that a closed circulation had developed and it was determined had developed into Tropical Depression Eight at 00:00 UTC that day while located about 210 nmi south-southeast of the Mouth of the Mississippi River. [5] [2] Dry air kept the depression from strengthening for 24 hours, but at 00:00 UTC on July 24, the depression strengthened into Tropical Storm Hanna. [2] This was confirmed by banding features becoming evident within the newly formed system and hurricane reconnaissance aircraft data indicating tropical storm-force winds inside the nascent storm at around 03:00 UTC that day. Hanna was the earliest eighth-named storm on record, surpassing Tropical Storm Harvey of 2005 by well over a week. [6]
Despite being a large and sprawling storm surrounded by dry air, Hanna continued to steadily intensify as it approached Texas, defying forecasts by strengthening faster than anticipated. This also caused Hanna to dive farther to the south than originally predicted. Microwave imagery around 19:44 UTC on July 24 showed a developing mid-level eye within a significantly improved inner core of convection. These features continue to organize and become better defined as the system moved west-southwestward and at 12:00 UTC on July 25, Hanna strengthened into hurricane. Hanna strengthened further despite increasing land interaction, developing an eye of 30–35 nmi on radar and satellite imagery. Reaching a peak intensity of 90 mph (140 km/h) and a pressure of 973 mbar at 18:00 UTC, the storm made landfall at Padre Island, Texas, at 22:00 UTC. Hanna then moved over the Laguna Madre and made a second landfall in Kenedy County, Texas, 10 nmi north of Port Mansfield, Texas, at 23:15 UTC with the same wind speeds, although its pressure had risen by a millibar. Once inland, Hanna rapidly weakened, becoming a tropical storm by 06:00 UTC on July 26. Around 12:00 UTC that same day, the weakening Hanna moved into Northeastern Mexico and dropped to tropical depression status at 18:00 UTC when it was located near Monterrey, Mexico, at which time the responsibility of advisories was passed to the Weather Prediction Center. [2] [7] The last advisory by the WPC was later issued that day and Hanna dissipated over the mountainous terrain by 00:00 UTC on July 27. [8] [2]
The National Weather Service first issued a tropical storm watch for the coast of Texas between Port Mansfield and High Island at 03:00 UTC on July 23 when Tropical Depression Eight—the precursor to Hurricane Hanna—was first designated. [9] [10] The Texas Division of Emergency Management (TDEM) organized personnel and assets from state agencies to assist local preparations for the approaching storm. [11] These included search-and-rescue teams from Texas A&M Task Force 1 and the Texas Department of Public Safety. The Department of Public Safety also provided aircraft, mainly helicopters, for similar purposes. [12] [13] [14] Search and rescue and cleanup crews were also readied for Hanna's aftermath. [15] The United States Coast Guard urged mariners to clear the waters off the Texas coast and bring large vessels to safety at inland marinas. [16] While Hanna was not expected to pose a significant threat to the Houston area, local emergency management placed high-water rescue trucks and crews on standby. [17] [18] The active tropical storm watch was superseded by a tropical storm warning between Port Mansfield and San Luis Pass at 21:00 UTC on July 23. [19] The next day, a hurricane warning was issued for the Texas coast between Baffin Bay and Mesquite Bay; [20] the warning was later expanded southward to Port Mansfield. [21] Additionally, a tornado watch was issued for a portion of Southeast Texas. [22]
The Padre Island National Seashore and beaches along the Nueces Bay and the Gulf of Mexico around Corpus Christi were closed in anticipation of storm-enhanced tides. [23] [24] Both Texas A&M University–Corpus Christi and Del Mar College limited operations amid the storm's passage. [24] Hanna threatened Texas concurrent with an increase in viral cases associated with the COVID-19 pandemic. [25] At least one drive-through testing site for COVID-19 was closed in Corpus Christi in preparation for Hanna while the pandemic limited the number of emergency management personnel in the Rio Grande Valley. [26] [27] Both the Corpus Christi Regional Transportation Authority and the Lower Rio Grande Valley Development Council cancelled their bus services for two days. [28] [24] [29] The Port of Corpus Christi closed to all ship traffic on July 24 and Corpus Christi International Airport cancelled most flights on July 25. [30] [29]
A local state of disaster lasting seven days was declared by County Judge Richard F. Cortez in Hidalgo County on July 25 due to the threat of "catastrophic flooding." A state of disaster was also declared in Cameron County and San Patricio County. [25] [15] [31] [32] [29] Texas Governor Greg Abbott issued a disaster declaration for 32 counties across South Texas later that day shortly before Hanna struck the state. [26] [33] [15] Abbott also appealed for a federal disaster declaration and public assistance from the Federal Emergency Management Agency (FEMA). [15] Several counties and municipalities distributed sandbags ahead of Hanna's arrival. [34] [35] [36] Willacy County officials recommended the evacuation of people from Port Mansfield. [37] [38] [39] A voluntary evacuation order for Baffin Bay, Loyola Beach, Ricardo, and Riviera was issued by Kleberg County Judge Rudy Madrid, [40] while a voluntary evacuation was recommended by San Patricio County Judge David R. Krebs for vulnerable areas. [24] Evacuation shelters were opened across the Rio Grande Valley. [41] A FEMA Dome was opened as a shelter in Kingsville at H.M. King High School and the Freeman Coliseum in San Antonio was repurposed as a reception center for evacuees with assistance from the American Red Cross. [33] [40] [30] [12] [13] [14] The Texas National Guard and state agencies sent 17 teams to test evacuees for COVID-19. [30] In Guadalupe, Nuevo León, a Mexican league soccer match was postponed as a precautionary measure. [42]
In Texas, where the storm made landfall, around 194,000 residents in the Rio Grande Valley and surrounding areas lost power due to Hanna. [43] [44] Hanna also dumped several inches of rain causing widespread flash flooding in the same region, while it also caused downed trees and ripped roofs from homes. Wind gusts reached up to 110 mph (180 km/h) and storm surge reached as high as 6.24 ft (1.90 m) at landfall. [45] [33] [46] The Bob Hall Pier in Corpus Christi was extensively damaged and eventually collapsed partially due to high winds and storm surge. [47] The Art Museum of South Texas’ first floor and outdoor exhibits at the Texas State Aquarium were inundated by storm surge from Corpus Christi Bay. [48] Areas affected by Hanna were already struggling due to a surge of COVID-19 cases in the region. [49] Several marinas and boats on the coastline were severely damaged. [50] Three individuals had to be rescued from a sinking sailboat on a marina off the coast. [51] Many streets and highways later became inaccessible for much of July 25 and 26. [52]
Hanna caused significant crop damage, totaling to $176.6 million (2020 USD). [53] In Port Mansfield, 40% of homes received severe structural damage. [54] Near Laguna Madre, a few boat garages were damaged by high winds. [55] The cities of Mission, McAllen, and Weslaco were also placed under flash flood emergencies due to Hanna's rainbands. [52] Roads in Mission became impassible due to flooding. [56] In Roma, a tin roof was blown off a gas station. [57] In McAllen, a fast food restaurant sign was toppled, and a canal overflowed, flooding numerous roads. In Los Barreras, the roof of a carport was blown away. [58]
As Hanna moved further inland and weakened on July 26, the storm unleashed copious amounts of rainfall in South Texas, with rainfall totals reaching up to 15 in (380 mm). [25] Additionally, Hanna's outer bands caused widespread tornado warnings across South Texas and five EF0 tornadoes were confirmed to have touched down. [59] [2] One of these tornadoes briefly touched down and damaged two homes and a hangar in Brownsville/South Padre Island International Airport, and moved a Boeing 737 aircraft. [60] [2] Even a day following landfall much of the areas near the coast in Corpus Christi remained submerged from storm surge and flash flooding. [51] After sheltering for the storm, thousands of American Electric Power crews worked for days to restore power, but were delayed to some areas due to high water, especially in the Rio Grande Valley. [61] [62] As of 14 September 2020 [update] , economic losses were estimated at or above US$775 million. [63]
On July 26, streets in Monterrey were flooded by Hanna after it had been downgraded to a tropical storm. Other parts of the states of Nuevo León, Coahuila, and Tamaulipas were similarly affected. [64] Electrical power was cut in large sections of Monterrey and neighboring areas, while the road linking Monterrey to Reynosa, Tamaulipas, was closed due to flooding. [64] In the city of Matamoros, across the border from Brownsville, Texas, heavy rain and winds damaged tents in a refugee camp housing an estimated 1,300 asylum seekers. [65] Reynosa was one of the most affected cities in Mexico, where 45 neighborhoods were damaged, two people were killed, and 200 people were displaced due to Hanna's impact. [66] One of the deaths was caused by drowning in Hanna's floodwaters after the victim suffered a seizure. [67] A maternity hospital was flooded on July 26. [68] [67]
An 11-year-old child was reported missing after falling into an overflowing stream in Monterrey, where extensive flooding and fallen trees were reported. [64] [69] A 35-year-old woman and her daughter were killed in Ramos Arizpe, Coahuila. [70] Total economic losses in Mexico were at least US$100 million. [63]
The precursor disturbance to Hanna dropped heavy rain to parts of Hispaniola, the Florida Keys and Cuba. In Pensacola, Florida, a 33-year-old police deputy was drowned by rip currents while trying to save his 10-year-old son in Sandestin Beach. In portions of Louisiana, Mississippi, Alabama, and the Florida Panhandle, the outer bands of Hanna brought heavy rainfall, even threatening street flooding in New Orleans. [71] [72]
Due to the extensive damage to property in the southern part of the state, Governor Greg Abbott issued a declaration of disaster for 32 counties affected by the storm. The Federal Emergency Management Agency (FEMA) and President Donald Trump granted a Federal Emergency Declaration request for Public Assistance. This allowed the Federal government to provide emergency protective measures, such as Federal assistance and reimbursement for mass care including evacuation and shelter support at 75 percent federal funding. [73] Three days after Hanna made landfall, Governor Greg Abbott visited Corpus Christi and praised the preparations for Hanna stating that no deaths occurred in Texas in association with the storm. [74]
It was initially reported that federal funds would be provided to tear down Bob Hall Pier due to the extensive damage it received during Hanna. [75] However, as of January 2021 the county has not been able to receive FEMA funding for the pier. [76]
A video showing the collapse of part of the Mexican-United States border wall was widely shared on social media, with the cause attributed to Hanna's high winds; [65] the United States Army Corps of Engineers later clarified that the collapse had occurred over a month earlier, in the state of New Mexico, and was completely unrelated to Hanna. [77] Asylum seekers at a camp in Matamoros were angered due to the lack of warning with Hanna. A worker for the Global Response Management (GRM) and Resource Centre Matamoros (RCM) said that nothing was damaged but a few tents and that they wanted to provide basic human rights for residents at asylum seeker camps. [78]
Hurricane Celia was the costliest tropical cyclone in Texas history until Hurricane Alicia in 1983. The third named storm, second hurricane, and first major hurricane of the 1970 Atlantic hurricane season, Celia developed from a tropical wave in the western Caribbean Sea on July 31. Initially, the depression tracked north-northwestward, crossing over western Cuba on August 1 and becoming Tropical Storm Celia. Heavy rains on the island caused severe flooding, leading to five fatalities. The storm entered the Gulf of Mexico, and due to the warm sea surface temperatures, Celia intensified into a hurricane later that day. Storm surge and swells lashed the west coast of Florida, especially the Panhandle, causing eight people to drown. On August 2 and early on August 3, Celia slightly weakened, however, the storm underwent rapid intensification and deepening, and peaked as a Category 4 hurricane at landfall with winds of 140 mph (220 km/h) later on August 3.
The 1921 Atlantic hurricane season was an active hurricane season, with 12 tropical cyclones forming. Among them, seven became tropical storms, of which five strengthened into hurricanes. Furthermore, two of these strengthened into a major hurricane, Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale, the most since the 1917 season. The first system, a tropical depression, developed on June 1, while the last, a tropical storm, dissipated on November 25. Of note, three tropical cyclones co-existed with another during the season.
The 1909 Atlantic hurricane season was an average Atlantic hurricane season. The season produced thirteen tropical cyclones, twelve of which became tropical storms; six became hurricanes, and four of those strengthened into major hurricanes. The season's first storm developed on June 15 while the last storm transitioned into an extratropical cyclone on November 14. The most notable storm during the season formed in late August, while east of the Lesser Antilles. The hurricane devastated the Lesser Antilles, the Greater Antilles, and Mexico, leaving around 4,000 fatalities and more than $50 million (1909 USD) in damage.
The 1919 Florida Keys hurricane was a massive and damaging tropical cyclone that swept across areas of the northern Caribbean Sea and the United States Gulf Coast in September 1919. Remaining an intense Atlantic hurricane throughout much of its existence, the storm's slow movement and sheer size prolonged and enlarged the scope of the hurricane's effects, making it one of the deadliest hurricanes in United States history. Impacts were largely concentrated around the Florida Keys and South Texas areas, though lesser but nonetheless significant effects were felt in Cuba and other areas of the United States Gulf Coast. The hurricane's peak strength in Dry Tortugas in the lower Florida Keys made it one of the most powerful Atlantic hurricanes to make landfall in the United States.
The 2008 Atlantic hurricane season was the most destructive Atlantic hurricane season since 2005, causing over 1,000 deaths and nearly $50 billion in damage. The season ranked as the third costliest ever at the time, but has since fallen to ninth costliest. It was an above-average season, featuring sixteen named storms, eight of which became hurricanes, and five which further became major hurricanes. It officially started on June 1 and ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. However, the formation of Tropical Storm Arthur caused the season to start one day early. It was the only year on record in which a major hurricane existed in every month from July through November in the North Atlantic. Bertha became the longest-lived July tropical cyclone on record for the basin, the first of several long-lived systems during 2008.
Hurricane Bret was the first of five Category 4 hurricanes that developed during the 1999 Atlantic hurricane season and the first tropical cyclone since Hurricane Jerry in 1989 to make landfall in Texas at hurricane intensity. Forming from a tropical wave on August 18, Bret slowly organized within weak steering currents in the Bay of Campeche. By August 20, the storm began to track northward and underwent rapid intensification on August 21. After this period of strengthening, Bret attained its peak intensity with winds of 145 miles per hour (233 km/h) and a barometric pressure of 944 mbar (hPa; 27.9 inHg). Later that day, the storm weakened to a Category 3 hurricane and made landfall on Padre Island, Texas. Shortly thereafter, the storm weakened further, becoming a tropical depression 24 hours after moving inland. The remnants of the storm eventually dissipated early on August 26 over northern Mexico.
Hurricane Dolly caused flooding throughout Mexico in August 1996. The fourth named storm and third hurricane of the season, Dolly developed from a tropical wave to the west-southwest of Jamaica on August 19. Initially a tropical depression, the system strengthened into a tropical storm about twelve hours later. Dolly headed westward and intensified into a Category 1 hurricane late on August 20. It then made landfall near Chetumal, Quintana Roo. The system weakened to a tropical depression on August 21. Later that day or early on August 22, Dolly emerged into the Bay of Campeche and quickly re-strengthened into a tropical storm. The storm deepened further and was upgraded to a hurricane again by midday on August 23; Dolly simultaneously peaked with winds of 80 mph (130 km/h). Around that time, it struck between Tuxpan, Veracruz, and Tampico, Tamaulipas. Dolly quickly weakened to a tropical depression early on August 24, but remained intact while crossing Mexico and dissipated over the eastern Pacific Ocean on August 25.
Tropical Storm Arlene brought torrential rainfall to the western United States Gulf Coast, particularly to the U.S. state of Texas, in June 1993. The first named storm of the 1993 Atlantic hurricane season, Arlene developed from an area of low pressure in the Bay of Campeche on June 18. The depression slowly strengthened as it tracked west-northwestward and later north-northwestward across the western Gulf of Mexico. Arlene was subsequently upgraded to a tropical storm on June 19, but failed to intensify further due to its proximity to land. The cyclone then made landfall on Padre Island, Texas, with winds of 40 mph (65 km/h) and degenerated into a remnant disturbance on June 21.
Tropical Storm Dean was a short-lived storm that formed in late July 1995 and lasted into early August. It was the fourth named storm of the 1995 Atlantic hurricane season. It spent most of its life as a tropical depression, and briefly gained tropical storm status before its landfall on the Texas coast on July 30. After landfall, it dissipated over central Texas on August 2. The impacts from Dean were minimal, mainly due to heavy rain in Oklahoma and Texas that caused localized coastal and inland flooding. Two F0 Tornadoes touched down in Texas as a result of Dean's landfall. Also, Twenty families had to be evacuated in Chambers County, due to flooding in the area. One fatality was recorded as a result of flooding in Oklahoma. Several highways were flooded out in Oklahoma, which impeded travel in the state. In addition approximately $500,000 worth of damage was recorded in the aftermath of Dean.
The 2020 Atlantic hurricane season is the most active Atlantic hurricane season on record, in terms of number of systems. It featured a total of 31 tropical or subtropical cyclones, with all but one cyclone becoming a named storm. Of the 30 named storms, 14 developed into hurricanes, and a record-tying seven further intensified into major hurricanes. It was the second and final season to use the Greek letter storm naming system, the first being 2005, the previous record. Of the 30 named storms, 11 of them made landfall in the contiguous United States, breaking the record of nine set in 1916. During the season, 27 tropical storms established a new record for earliest formation date by storm number. This season also featured a record ten tropical cyclones that underwent rapid intensification, tying it with 1995, as well as tying the record for most Category 4 hurricanes in a singular season in the Atlantic Basin. This unprecedented activity was fueled by a La Niña that developed in the summer months of 2020, continuing a stretch of above-average seasonal activity that began in 2016. Despite the record-high activity, this was the first season since 2015 in which no Category 5 hurricanes formed.
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.
The 2021 Atlantic hurricane season was the third-most active Atlantic hurricane season on record in terms of number of tropical cyclones, although many of them were weak and short-lived. With 21 named storms forming, it became the second season in a row and third overall in which the designated 21-name list of storm names was exhausted. Seven of those storms strengthened into a hurricane, four of which reached major hurricane intensity, which is slightly above-average. The season officially began on June 1 and ended on November 30. These dates historically describe the period in each year when most Atlantic tropical cyclones form. However, subtropical or tropical cyclogenesis is possible at any time of the year, as demonstrated by the development of Tropical Storm Ana on May 22, making this the seventh consecutive year in which a storm developed outside of the official season.
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 Amanda and Tropical Storm Cristobal were two related, consecutive tropical storms that affected Central America, southern Mexico, the Central United States, and Canada in late May and early June 2020. The first tropical cyclone formed in the East Pacific and was named Amanda. After crossing Central America, it regenerated into a second one in the Gulf of Mexico and was named Cristobal. Amanda was the second tropical depression and the first named storm of the 2020 Pacific hurricane season, and Cristobal was the third named storm of the extremely active 2020 Atlantic hurricane season, and the earliest third named storm in the North Atlantic Ocean on record. Cristobal's regeneration date in the North Atlantic eclipsed the date set by Tropical Storm Colin in 2016, which formed on June 5. It was also the first Atlantic tropical storm formed in the month of June since Cindy in 2017, and the first June tropical cyclone to make landfall in Mexico since Danielle in 2016.
Hurricane Marco was the first of two tropical cyclones to threaten the Gulf Coast of the United States within a three-day period. The thirteenth named storm and third hurricane of the record-breaking 2020 Atlantic hurricane season, Marco developed from a fast-moving tropical wave west of the Windward Islands and south of Jamaica on August 20. The fast motion of the wave inhibited intensification initially, but as the wave slowed down and entered a more favorable environment, the system developed into a tropical depression, which in turn rapidly intensified into a strong tropical storm. Due to strong wind shear, Marco's intensification temporarily halted. However, after entering the warm waters of the Gulf of Mexico on August 23, Marco briefly intensified into a hurricane, only to quickly weaken later that evening due to another rapid increase in wind shear. Marco subsequently weakened to a tropical depression before degenerating into a remnant low early the next morning. Marco's remnants subsequently dissipated on August 26.
Tropical Storm Beta was a tropical cyclone that brought heavy rainfall, flooding, and severe weather to the Southeastern United States in September 2020. The twenty-third tropical depression and twenty-third named storm of the record-breaking 2020 Atlantic hurricane season, Beta originally formed from a trough of low pressure that developed in the northeastern Gulf of Mexico on September 10. The low moved slowly southwestward, with development hampered initially by the development of nearby Hurricane Sally. After Sally moved inland over the Southeastern United States and weakened, the disturbance became nearly stationary in the southwestern Gulf, where it began to organize. By September 16, the storm had gained a low-level circulation center and had enough organization to be designated as Tropical Depression Twenty-Two. The system held its intensity for a day due to the influence of strong wind shear and dry air, before eventually attaining tropical storm strength. It slowly moved northward and intensified to a mid-range tropical storm before dry air and wind shear halted its intensification. Beta then became nearly stationary on September 19, before starting to move west towards the Texas coast the next day, weakening as it approached. On September 21, Beta made landfall near Matagorda Peninsula, Texas as a minimal tropical storm. It subsequently weakened to a tropical depression the next day before becoming post-tropical early on September 23. Its remnants moved northeastward, before the center elongated and merged with a cold front early on September 25.
Hurricane Gamma was a Category 1 hurricane that brought heavy rains, flooding, and landslides to the Yucatán Peninsula in early October 2020. The twenty-fifth depression, twenty-fourth named storm and ninth hurricane of the extremely active 2020 Atlantic hurricane season, Gamma developed from a vigorous tropical wave that had been monitored as it was entering the Eastern Caribbean on September 29. The wave moved westward and slowed down as it moved into the Western Caribbean, where it began to interact with a dissipating cold front. A low formed within the disturbance on October 1 and the next day, it organized into a tropical depression. It further organized into Tropical Storm Gamma early the next day. It continued to intensify and made landfall as a minimal hurricane near Tulum, Mexico, on October 3. It weakened over land before reemerging in the Gulf of Mexico. Gamma then briefly restrengthened some before being blasted by high amounts of wind shear, causing it to weaken again. It made a second landfall as a tropical depression in Nichili, Mexico on October 6 before dissipating as it was absorbed by the approaching Hurricane Delta.
Hurricane Grace was the strongest tropical cyclone to make landfall in the Mexican state of Veracruz. Grace impacted much of the Leeward Islands and Greater Antilles as a tropical storm, before causing more substantial impacts in the Yucatán Peninsula and Veracruz as a hurricane. It was the seventh named storm, second hurricane, and first major hurricane of the 2021 Atlantic hurricane season. Originating from a tropical wave in the Main Development Region, the primitive system tracked west-northwest across the Atlantic Ocean towards the Antilles, becoming a tropical depression on August 14. It strengthened into Tropical Storm Grace later the same day, but weakened back to a depression due to an unfavorable environment. After moving near Haiti as a tropical depression, it strengthened back to a tropical storm and became a hurricane on August 18, reaching an initial peak intensity with maximum sustained winds of 80 mph (130 km/h) and a pressure of 986 mbar (29.12 inHg). It weakened back to a tropical storm after its landfall in the Yucatán Peninsula and emerged into the Bay of Campeche, entering a very favorable environment for intensification hours later. Grace then rapidly intensified into a Category 3 hurricane with winds of 120 mph (190 km/h) in about 24 hours. The storm made its final landfall in the state of Veracruz at peak intensity and quickly degenerated into a remnant low over mainland Mexico on August 21; however, its remnants later regenerated into Tropical Storm Marty in the Eastern Pacific on August 23.
Tropical Storm Harold was a moderate tropical storm that made landfall in South Texas in August 2023. The eighth named storm of the 2023 Atlantic hurricane season, Harold developed from a tropical wave that entered the Gulf of Mexico on August 20, after passing through the Bahamas and Straits of Florida. The system steadily organized over the following days, over record-warm sea-surface temperatures in the Gulf, as it progressed westward. Although the disturbance had not become organized enough to become a tropical cyclone yet, due to the threat it posed to southern Texas, the United States–based National Hurricane Center (NHC) initiated advisories on the system as Potential Tropical Cyclone Nine on August 21. The disturbance organized into a tropical depression six hours later, before strengthening into a tropical storm the following morning and receiving the name Harold. Harold continued to strengthen as it moved quickly westward, and the cyclone made landfall on Padre Island, Texas, around 15:00 UTC on August 22, as a 60 mph (95 km/h) tropical storm. Harold quickly weakened as it moved inland over southern Texas and dissipated on August 23, though its remnant mid-level circulation and associated moisture affected the central United States for several more days.
