Tropical Storm Alex In late May, the mid-level remnants of
Hurricane Agatha in the Pacific basin interacted with a Central American Gyre. Consequently, a gradual increase in deep
convection occurred over the
Yucatán Peninsula and the northwestern Caribbean Sea, which led to the development of a
low-pressure area just north of the
Belize-Mexico border on June 2. After emerging into the southeastern Gulf of Mexico early the next day, the disturbance made multiple attempts at organizing into a tropical cyclone and attained tropical storm-force winds. However, strong
wind shear kept the system disorganized before it struck
Southwest Florida on June 4. Several hours later, the disturbance emerged into the Atlantic, where it developed into Tropical Storm Alex at 00:00
UTC on June 5 about north of
Grand Bahama. Additional intensification occurred as Alex moved east-northeastward due to mid-latitude westerly flow, reaching sustained winds of around 18:00 UTC. However, drier air caused Alex to weaken on the following day, with the storm transitioning into an extratropical cyclone at 12:00 UTC roughly north-northwest of Bermuda. The remnants of Alex were absorbed by a baroclinic zone early on June 7. Due to the threat the developing system posed to
Cuba, the
Florida Keys, and
South Florida, the
National Hurricane Center initiated advisories on it, designating it as
Potential Tropical Cyclone One. The precursor to Alex dropped heavy precipitation in these regions. There were four storm-related deaths in Cuba, while about 750 homes, of crops, According to AON, damages from flooding totaled at least USD$25 million in Cuba. However, it was later determined that flood damages in Florida were more than $350 million.
Tropical Storm Bonnie A low-altitude tropical wave entered the Atlantic from the west coast of Africa on June 22, producing a large but disorganized area of showers and thunderstorms. Thunderstorm activity increased by June 27, while a NOAA Hurricane Hunters mission reported tropical-storm-force winds but no well-defined closed circulation. However, due to the threat the system posed to the Lesser Antilles, the NHC initiated advisories on it as
Potential Tropical Cyclone Two later that same day. Later, after crossing the southern Windward Islands on June 28 and passing near the coast of Venezuela on the following day, the disturbance encountered more favorable conditions but failed to develop a distinct low-level circulation due to its fast forward speed and interaction with land. As the disturbance moved toward
Central America on the morning of July 1, it became sufficiently organized to be classified as Tropical Storm Bonnie. Embedded in an environment of low wind shear and warm seas, Bonnie started to steadily intensify. At 03:00 UTC on July 2, Bonnie made landfall near the Costa Rica–Nicaragua border at its peak intensity within the Atlantic with sustained winds of 60 mph (95 km/h). Bonnie then crossed Central America and exited into the Eastern Pacific basin around 12:00 UTC on July 2. On
Trinidad, floodwaters damaged at least 40 homes in one village and left approximately 200,000 people without potable water. In
Costa Rica, over 3,000 people evacuated as a result of flooding and mudslides, Over 10,000 people lost power during the storm in
Nicaragua. Four deaths occurred in the country, three after being swept away in rising rivers and one while attempting to rescue other people from a bus being carried away. Overall, Bonnie caused about $25 million in damage throughout the impacted regions. Colin became increasingly disorganized later that day, with its circulation becoming elongated due to the wind shear and continued land interaction. By 18:00 UTC on July 2, Colin had fallen to tropical depression intensity. The storm continued to weaken rapidly, and its low-level circulation dissipated over northeastern South Carolina by the end of that day. However, only minor damage occurred overall. One person drowned at
Oak Island, North Carolina, due to rip currents generated by Colin. It then moved over a relatively cool part of the
Gulf Stream and weakened to a low-end Category 1 hurricane. The hurricane briefly re-intensified when it moved over marginally warm waters on September 7, but resumed a weakening trend shortly thereafter. Danielle weakened to a tropical storm early on September 8, before transitioning into an extratropical cyclone later that day. The remnant extratropical system meandered over the northeastern Atlantic before dissipating offshore
Portugal on September 15. One man was hospitalized after he was swept away by floodwaters. In
Manteigas, which had been ravaged by intense summer forest fires in nearby areas of the
Serra da Estrela mountain range, floods and landslides caused major damage and at least four vehicles were dragged into the
Zêzere River. Portuguese authorities also reported minor wind and flood damage in Lisbon and
Setúbal. Much of
Spain was put on yellow alert as wind, rain and thunderstorms triggered by the cyclone moved inland.
Hurricane Earl On August 25, a tropical wave emerged into the Atlantic from the west coast of Africa. Convective activity remained sporadic and disorganized for several days as the wave moved generally west-northwestward through an environment of dry air and unfavorable wind shear. However, convection markedly increased on September 1 as the system approached warm waters near the Lesser Antilles. Late on the following day, the system organized into Tropical Storm Earl approximately east of
Barbuda. Continuously unconducive wind shear prevented significant intensification before Earl turned northward on September 5 through a break in a subtropical ridge over the central Atlantic. Possibly due to a diffluent environment and favorable thermodynamic conditions, Earl intensified into a hurricane late on September 6. The storm briefly strengthened into a Category 2 hurricane early on September 8 but then weakened later that day, likely due to dry air. Around 12:00 UTC on September 9, Earl re-strengthened into a Category 2 hurricane. About 12 hours later, the hurricane peaked with sustained winds of 110 mph (175 km/h) and a minimum barometric pressure of as it accelerated northeastward in advance of a mid-latitude trough. However, Earl soon began losing tropical characteristics and transitioned into an extratropical cyclone around 18:00 UTC on September 10, about south of Cape Race, Newfoundland. The extratropical remnants executed a cyclonic loop south of Newfoundland before moving generally eastward across the Atlantic before dissipating late on September 15. During a period of rain fell in the
St. Johns area of Newfoundland and Labrador, causing the Waterford River to overflow, which led to urban flooding. Similar rainfall amounts were also reported in communities throughout the
Avalon Peninsula. Additionally, the cyclone generated rough surf which damaged the breakwater on the coast in the area of
Trepassey, causing localized flooding. Several of the
Leeward Islands recorded tropical storm-force winds and heavy rainfall, with up to of precipitation on Guadeloupe, leading to one death after the overflowing
Rivière des Pères swept away a house. torrential rains fell island-wide on Puerto Rico on exceeding in some regions, causing destructive flash flooding, landslides, and rockfalls that washed out or blocked numerous roads and bridges. In addition, the effects of the storm resulted in an island-wide power grid failure. A loss of approximately 90% of commercial crops also occurred. Overall, Fiona caused 23 deaths and about $2.5 billion in damage in Puerto Rico, making Fiona the island's third costliest tropical cyclone on record. In the Dominican Republic, heavy rainfall and hurricane-force winds destroyed more than 2,000 homes and damaged about 8,500 others, displacing over 43,000 people. More than 400,000 people lost electricity and 1.2 million people experienced a disruption of water services. Two deaths occurred in the country, However, additional strengthening was prevented as dry air intruded into Gaston. A blocking mid-level high pressure caused the storm to turn southeastward and then southwestward on September 23 and later to the west on the following day. A weather station at
Horta on
Faial Island measured a wind gust of as Gaston passed through. Convection diminished significantly as the storm continued westward and by 00:00 UTC on September 26, Gaston became extratropical about west-southwest of
Flores Island. The remnant low moved west-southwestward until dissipating about 48 hours later. Early on September 28, Ian struck
Dry Tortugas, Florida, with winds of 125 mph (205 km/h) as the storm headed north-northeastward along a broad trough and the western periphery of a subtropical ridge. Favorable conditions in the Gulf of Mexico then allowed another period of rapid deepening to commence. At 12:00 UTC on September 28, Ian briefly attained Category 5 status and peaked with maximum sustained winds of and a minimum barometric pressure of . the
ABC islands, and the northern coast of South America on with more than 100,000 dwellings damaged or destroyed in Pinar del Río Province alone. Significant storm surge inundation occurred along the coasts of the Gulf of
Guanahacabibes and Isla de la Juventud. Damage in Cuba totaled about $200 million. Bridges and roadways, especially along the coast or on the barrier islands, also suffered major impacts. In neighboring
Collier County, strong winds and storm surge inflicted major damage to more than 3,500 buildings and destroyed 33 others. The outerbands of Ian spawned 14 tornadoes in Florida, including an EF-2 tornado that caused significant damage to some condominiums and injured two people in
Kings Point. Ian also produced historic flooding across Central Florida due to a wide swath of rainfall totals generally ranging from ,
Tropical Storm Hermine On September 22, a tropical wave being monitored by the NHC emerged off the coast of West Africa into the tropical Atlantic east of
Cabo Verde. It quickly organized, becoming Tropical Depression Ten at 12:00 UTC on September 23, and then strengthened into Tropical Storm Hermine six hours later. It is one of few tropical cyclones
on record to form and track between the Cabo Verde Islands and the coast of Africa. Landslides blocked roads in about 690 locations. Floodwaters entered four homes in the capital city of
Santa Cruz de Tenerife. Additionally, more than 140 flights were cancelled across the
archipelago. Damage in the Canary Islands exceeded 10 million euro (US$9.8 million).
Tropical Depression Twelve On September 29, a tropical wave emerged into the Atlantic from the west coast of Africa. Showers and thunderstorms associated with the wave waned during the next few days as it tracked westward. However, a nearby
Kelvin wave enhanced the wave's convective activity beginning on October 3. By early the following day, the convection became more concentrated and organized around the center, resulting in the formation of Tropical Depression Twelve around 12:00 UTC about west-southwest of the Cabo Verde Islands. Moving generally northwestward due to a weakness in a mid-level ridge, the depression encountered strong wind shear, with the center of the cyclone becoming completely exposed from its convection by early the following day. Throughout the day on October 5, the depression's circulation became more elongated. A further increase in wind shear on October 6 caused the depression to degenerate into a surface trough approximately west-northwest of the Cabo Verde Islands. The trough associated with the remnants of the depression became indistinguishable within a few days.
Hurricane Julia A tropical wave emerged into the Atlantic from the west coast of Africa on September 26. While moving westward, the wave remained weak and consisted of little convection for the next few days. Convection became more concentrated as the wave reached the Caribbean, with the system organizing into a tropical depression early on October 7 near
Curaçao. A strong burst of deep convection developed near the center of the depression as it moved across the
Guajira Peninsula in the early morning of October 7, and soon afterward, it strengthened into Tropical Storm Julia over the adjacent southwestern Caribbean. Thereafter, Julia began moving in a more westward direction along the southern periphery of a building ridge. Low wind shear, high humidity at the mid-levels, and very warm seas caused the storm to intensify into a hurricane at 00:00 UTC on October 9. About six hours later, Julia peaked with maximum sustained winds of 85 mph (140 km/h). The storm then made landfall near
Laguna de Perlas, Nicaragua, at 07:15 UTC. Julia's relatively quick movement, as well as its passage across areas comparatively less rugged than to the north, caused the cyclone to only gradually weaken, falling to tropical storm intensity late on October 9. Early the following day, Julia emerged into the Pacific Ocean but quickly dissipated after striking
El Salvador several hours later. On October 5, the disturbance brought heavy thunderstorms to several of the Windward Islands and the Caribbean coast of South America. More than of rain fell in Trinidad and Tobago in less than a half hour, causing significant flash flooding. A few days later, heavy rainfall occurred in northern areas of Venezuela and Colombia, causing widespread flooding. There were 54 indirect flood fatalities in Venezuela. In Central America, flash flooding and associated mudslides caused widespread damage. Nicaragua suffered extensive flood damage totaling about $400 million. Over 1 million people across the country lost electricity during the storm. Additionally, Costa Rica, Honduras, and Panama reported damage to thousands of homes and significant crop losses. Altogether, there were at least 89 Julia-related fatalities: 54 in Venezuela, 14 in Guatemala, 10 in El Salvador, 5 in Nicaragua, 4 in Honduras, and 2 in Panama. Although satellite images that morning showed that the dense overcast around the storm's low-level center had become more symmetric overnight, with its heavy thunderstorms concentrated to the southeast of the center, dry air and wind shear snuffed out all of Karl's deep convection several hours later. Around 00:00 UTC on October 15, Karl degenerated into a remnant low. The remnants of Karl moved towards
Tabasco before dissipating about 24 hours later. which also forced the evacuation of more than a thousand people attending a religious event in
Pichucalco, Chiapas. Additionally, three storm-related fatalities were reported in Chiapas: one in Pichucalco and two in
Juárez.
Hurricane Lisa On October 17, a tropical wave emerged into the Atlantic from the west coast of Africa. After crossing the Lesser Antilles and entering the Caribbean on October 25, the wave decelerated. Interaction between the wave and a large mid-level trough spawned a broad low-pressure area on October 28. After convection consolidated and a well-defined center formed, the system developed into Tropical Storm Lisa at 12:00 UTC on October 31 about south of
Kingston, Jamaica. Dry air and wind shear allowed for only gradual intensification, although Lisa reached hurricane status on November 2. The storm strengthened slightly further that day, peaking with winds of 90 mph (150 km/h) and a minimum pressure of while making landfall in Belize near the mouth of the
Sibun River at 21:30 UTC. Lisa initially weakened quickly over the Yucatán Peninsula, falling to tropical storm intensity around 06:00 UTC on November 3 and then to tropical depression status six hours later. Despite Lisa emerging into the Gulf of Mexico early the following day, unfavorable conditions caused the storm to degenerate into a trough of low-pressure by 12:00 UTC on November 5 about northeast of
Veracruz. Throughout Belize, the hurricane destroyed about 500 homes and damaged around 5,000 others. Damage in the country totaled roughly $100 million. Lisa also brought heavy rains to southern Mexico.
Hurricane Martin A surface trough formed on October 25 about halfway between the Bahamas and Bermuda, partially due to a nearby upper-level shortwave trough. Three days later, a non-tropical low-pressure area formed along the surface trough. Although the low merged with a frontal boundary early on October 30, its remnants caused the development of an extratropical cyclone several hours later. By November 1, the extratropical system had shed its frontal characteristics and developed more deep convection. Consequently, Tropical Storm Martin formed about east-northeast of Bermuda around 12:00 UTC on November 1. Despite only marginally favorable sea temperatures and mid-level moisture, cold upper-level temperatures allowed the storm to strengthen gradually, becoming a Category 1 hurricane about 24 hours later as a ragged eye appeared on satellite imagery. At 06:00 UTC on November 3, Martin peaked with sustained winds of 85 mph (140 km/h) and a minimum pressure of . However, the storm became extratropical just six hours later approximately east of Cape Race, Newfoundland, due to its interaction with an approaching cold front. The remnants of Martin moved rapidly northward until being absorbed by a larger extratropical system southeast of Greenland early on November 5.
Hurricane Nicole A mid to upper-level trough crossed into western Atlantic from northeastern United States on November 3. After the trough interacted with the
Intertropical Convergence Zone on the following day, a large area of convection formed between the eastern Caribbean to just north of the Lesser Antilles. On November 5, a broad low developed just south of Hispaniola, before re-forming north of Puerto Rico on the next day. A further increase in convection led to the formation of Subtropical Storm Nicole early on November 7, roughly south-southwest of Bermuda. The system initially moved northwestward due to a low to mid-level ridge, before a cold front caused it to move westward to west-southwestward beginning on November 8. Convection consolidated further around the center, resulting in Nicole transitioning into a tropical storm around 18:00 UTC. At 17:00 UTC on November 9, Nicole struck
Marsh Harbour,
Great Abaco Island, Bahamas, with winds of 70 mph (110 km/h). Several hours later, the storm strengthened into a Category 1 hurricane while simultaneously striking Grand Bahama with winds of . At 07:45 UTC on November 10, Nicole made landfall near
Vero Beach, Florida, at the same intensity. Nicole quickly weakened to a tropical storm while crossing Central Florida. Later on November 10, the storm briefly emerged into the Gulf of Mexico near
Crystal River, before striking
Cedar Key and then the mouth of the
Aucilla River early the next day. Crossing into southwestern Georgia, the cyclone fell to tropical depression status. By 18:00 UTC on November 11, a mid-latitude trough absorbed Nicole over eastern North Carolina. Precipitation totals in Florida generally ranged from , leading to only minor flooding. With few observations of hurricane-force winds, mostly light wind damage occurred, although more than 300,000 businesses and households lost electricity due to the storm. However, days of strong on-shore wind flow onto the east coast of Florida produced storm surge that caused severe beach erosion, especially in
Brevard,
Flagler,
St. Johns, and Volusia counties. At least 107 structures suffered damage in Brevard County, with 10 deemed unsafe for occupancy. In Volusia County, almost 50 condominiums collapsed or were at risk of collapsing. Flagler County reported coastal flood damage, along with a loss of about of beach sand and sand dunes. A total of 299 structures experienced some degree of impact in St. Johns County, mostly due to erosion. Five indirect deaths occurred in Florida. Nicole and its remnants produced widespread, but mostly light precipitation across the Southeastern United States before being absorbed by the frontal system, although of rain fell near
Foscoe, North Carolina. Storm surge caused coastal flooding as far north as Charleston, South Carolina. The low emerged over the Gulf early on August 19 producing disorganized showers. Due to the threat the developing system posed to northeastern Mexico and
South Texas, the NHC initiated advisories on it as
Potential Tropical Cyclone Four at 21:00 UTC that same day. Later that day, it moved inland, crossing the coast about southwest of the mouth of the
Rio Grande. With that, the window of opportunity for tropical development closed, and the NHC issued its last advisory on the system at 03:00 UTC on August 21. The disturbance brought heavy rain to coastal
Tamaulipas and coastal South Texas, but left no significant impacts. == Storm names ==
