Hurricane Hortense was the first tropical cyclone to make landfall in Guadeloupe and Puerto Rico since Hurricane Hugo in 1989, and the second most intense hurricane during the 1996 Atlantic hurricane season. The eighth tropical cyclone, eighth named storm, and sixth hurricane of the season. Hortense developed on September 3 from a tropical wave in the central Atlantic Ocean. Initially a tropical depression, it headed westward without significant strengthening for four days due to unfavorable upper-level winds. While nearing the Lesser Antilles upper-level winds decreased, allowing the depression to become Tropical Storm Hortense on September 7. Hortense crossed Guadeloupe on September 8 and entered the Caribbean Sea. By on the following day, it was upgraded to a hurricane while curving northwestward. Hortense made landfall in Puerto Rico on September 9 and brushed the Dominican Republic shortly thereafter. After re-entering the Atlantic, Hortense began to substantially strengthen and peaked as a 140 mph (220 km/h) Category 4 hurricane early on September 13. Thereafter, the storm steadily weakened as it tracked rapidly north-northeastward. Early on September 15, Hortense made landfall in Nova Scotia as a minimal Category 1 hurricane. It quickly weakened further to a tropical storm before re-entering the Atlantic to the south of Newfoundland. Late on September 15, Hortense transitioned into an extratropical cyclone and subsequently merged with a frontal system about 24 hours later.
The 1975 Atlantic hurricane season featured the first tropical storm to be upgraded to a hurricane based solely on satellite imagery – Hurricane Doris. The season officially began on June 1 and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The season was near average, with nine tropical storms forming, of which six became hurricanes. Three of those six became major hurricanes, which are Category 3 or higher on the Saffir–Simpson scale. The first system, Tropical Depression One, developed on June 24. Tropical Storm Amy in July caused minor beach erosion and coastal flooding from North Carolina to New Jersey, and killed one person when a ship capsized offshore North Carolina. Hurricane Blanche brought strong winds to portions of Atlantic Canada, leaving about $6.2 million (1975 USD) in damage. Hurricane Caroline brought high tides and flooding to northeastern Mexico and Texas, with two drownings in the latter.
The 1959 Escuminac disaster was considered the worst fishing-related disaster in New Brunswick in 100 years. It occurred due to the extratropical remnants of an Atlantic hurricane. The storm was the third tropical cyclone and first hurricane of the 1959 Atlantic hurricane season, and developed from a tropical wave in the central Gulf of Mexico on June 18. It headed rapidly northeastward and struck Florida later that day. Shortly after entering the Atlantic Ocean, it strengthened into a tropical storm later on June 18. By the following day, it had strengthened into a hurricane. However, it transitioned into an extratropical cyclone about six hours later. The remnants struck Atlantic Canada, once in Nova Scotia and again in Newfoundland before dissipating on June 21.
The 1948 Atlantic hurricane season featured the first tropical cyclone before the month of June since 1940. The season officially began on June 15, 1948, and lasted until November 15, 1948. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. There were 10 tropical cyclones; six storms attained hurricane status, and four storms intensified into major hurricanes, which are Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale. Operationally, it was believed that a weak tropical disturbance formed over the southeast Bahamas in May and moved northwest into the Georgia coast near Savannah. This system was later excluded from HURDAT. The seventh tropical cyclone was not operationally considered a tropical cyclone, but was later added to HURDAT.
The 1937 Atlantic hurricane season was a below-average period of tropical cyclone activity in the North Atlantic, featuring eleven tropical storms; of these, four became hurricanes. One hurricane reached major hurricane intensity, equivalent to a Category 3 or higher on the modern Saffir–Simpson scale. The United States Weather Bureau defined the season as officially lasting from June 16 to October 16. Tropical cyclones that did not approach populated areas or shipping lanes, especially if they were relatively weak and of short duration, may have remained undetected. Because technologies such as satellite monitoring were not available until the 1960s, historical data on tropical cyclones from this period are often not reliable. As a result of a reanalysis project which analyzed the season in 2012, a tropical storm and a hurricane were added to the Atlantic hurricane database (HURDAT). The official intensities and tracks of all storms were also revised by the reanalysis. The year's first storm formed on July 29 in the Gulf of Mexico, and the final system, a hurricane, dissipated over open ocean on October 21.
The 1927 Atlantic hurricane season featured no hurricane landfalls in the United States, in contrast to the four hurricanes that struck the United States in the previous season. Overall, the season was relatively inactive, with eight tropical storms, four of which became hurricanes. One of these became a major hurricane, which is Category 3 or higher on the modern day Saffir–Simpson hurricane wind scale. The first system, a tropical depression, developed on August 13, while the final cyclone, a tropical storm, merged with a cold front on November 21. The most significant storm of the season was Hurricane One, nicknamed the Nova Scotia hurricane. The sole major hurricane, this storm resulted in between 173 and 192 deaths in Atlantic Canada, mostly from capsized and missing ships offshore. On land, the storm left about $1.7 million (1927 USD) in damage, with much of the damage occurring in Nova Scotia. Additionally, the fourth, fifth, and sixth tropical storms brought minor impact to Bermuda, South Carolina, and Cuba, respectively.
The 1923 Atlantic hurricane season featured 11 tropical cyclones, 9 of which intensified into tropical storms, the most since 1916. Four of the tropical storms intensified into hurricanes, one of which reached major hurricane intensity—Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale. No tropical storms or hurricanes formed in or entered the Caribbean Sea. The first known system, a tropical depression, formed on June 19, while the last known system, a tropical storm, transitioned into an extratropical cyclone on October 26. A total of Additionally, an October tropical depression was previously recognized as a tropical storm until reanalysis in 2009, while the first and third tropical storms were added to the Atlantic hurricane database that year. The sixth, seven, and eight storms as well as the October tropical depression existed simultaneously on October 16.
The 1917 Atlantic hurricane season featured nine known tropical cyclones, four of which became tropical storms. The first system appeared on July 6 east of the Windward Islands. After crossing the islands and traversing the Caribbean Sea, the storm struck Honduras, Belize, and Mexico, before dissipating on July 14. After more than three weeks without tropical cyclogenesis, another tropical storm developed west of Bermuda. As the storm brushed eastern New England, four ships sank near Nantucket, causing 41 fatalities. The same cyclone brought damaging winds to Nova Scotia before transitioning into an extratropical cyclone on August 10.
The 1900 Atlantic hurricane season featured the Galveston hurricane, the deadliest natural disaster in the history of the United States. A total of 10 tropical cyclones formed, seven of which intensified into a tropical storm. Three of those made landfall in the United States. The first system was initially observed over the central Atlantic Ocean on January 17, while the final storm transitioned into an extratropical cyclone on October 28. These dates fall within the period with the most tropical cyclone activity in the Atlantic. Every storm of the season except the seventh system existed simultaneously with another tropical cyclone.
Hurricane Gustav was a Category 2 hurricane that paralleled the East Coast of the United States in September 2002 during the 2002 Atlantic hurricane season. It was the seventh named storm and first hurricane of the season. Initially a subtropical depression north of the Bahamas, Gustav passed just to the east of the Outer Banks, North Carolina as a tropical storm before traveling northeastward, making two landfalls in Atlantic Canada as a Category 1 hurricane. The storm was responsible for one death and $100,000 in damage, mostly in North Carolina. The interaction between Gustav and a non-tropical system produced strong winds that caused an additional $240,000 (2002 USD) in damage in New England, but this damage was not directly attributed to the hurricane.
Tropical Storm Beryl was the third tropical storm of the 2006 Atlantic hurricane season. Developing from a tropical disturbance on July 18, it tracked generally northward, and strengthened to attain peak winds of 60 mph (95 km/h) under generally favorable conditions. After turning to the northeast, Beryl weakened over cooler waters. On July 21 it struck the island of Nantucket, and shortly thereafter it became extratropical. The extratropical remnants continued northeastward through Nova Scotia, and on July 22 it merged with an approaching cold front.
The 1927 Nova Scotia hurricane was the deadliest tropical cyclone striking Canada in the 20th century. The first observed storm of the season, this cyclone developed from a tropical wave over the deep tropics of the Atlantic Ocean on August 18. Initially a tropical storm, it moved west-northwestward and intensified into a Category 1 hurricane on the modern day Saffir–Simpson hurricane wind scale by August 19. The storm intensified significantly over the next few days, and by August 22, it peaked as a Category 3 hurricane with maximum sustained winds of 125 mph (205 km/h). Around that time, the system began curving northwestward and later northward. By August 23, it turned to the north-northeast and then began weakening on August 24. Thereafter, the storm accelerated toward Atlantic Canada. Late on August 24, the hurricane struck near Yarmouth, Nova Scotia, as a Category 2 hurricane, just before becoming extratropical.
Hurricane Karen was a hurricane of non-tropical origin that formed in October of the 2001 Atlantic hurricane season. It developed out of the interaction between a cold front and an upper level trough on October 10 located to the south of Bermuda, and quickly strengthened as an extratropical storm. The storm passed near Bermuda on October 12, producing hurricane-force winds on the island. It then organized, becoming a subtropical cyclone on the 12th and a tropical cyclone on the 13th. Karen strengthened to reach 80 mph (130 km/h) winds as a Category 1 hurricane on the Saffir-Simpson Hurricane Scale, and after weakening over cooler waters, it made landfall on Nova Scotia as a tropical storm. It quickly became extratropical.
Hurricane Michael of the 2000 Atlantic hurricane season caused widespread, but relatively minor damage in Atlantic Canada. The seventeenth tropical cyclone, thirteenth named storm, and eighth hurricane of the season, Michael developed from a non-tropical system to the southwest of Bermuda on October 15. The system was initially subtropical, but rapidly acquired tropical characteristics by October 17. Michael quickly strengthened into a hurricane later that day. By October 20, Michael peaked as a Category 2 hurricane on the Saffir-Simpson hurricane wind scale at a relatively high latitude of 44°N. The storm weakened slightly to a Category 1 hurricane and became extratropical shortly before making landfall in Newfoundland on October 20.
The November 2001 Atlantic Canada storm complex was a powerful coastal storm that included the remnants of North Atlantic hurricanes Michelle and Noel. The low intensified as it moved westward into Atlantic Canada on November 6, reaching a minimum pressure of 946 mbars. The storm turned to the northeast and emerged into the Atlantic Ocean on November 8. It produced strong winds throughout Atlantic Canada, including gusts of up to 96 mph (154 km/h) at the Confederation Bridge in Prince Edward Island. High waves caused damage along the coastlines, while high winds left up to 100,000 without power. Overall damage was minor, and no casualties were reported.
The 1924 Atlantic hurricane season featured the earliest known Category 5 hurricane – a tropical cyclone with maximum sustained winds exceeding 155 mph (250 km/h). The first system, Tropical Storm One, was first detected in the northwestern Caribbean Sea on June 18. The final system, an unnumbered tropical depression, dissipated on November 24. These dates fall within the period with the most tropical cyclone activity in the Atlantic. Of the 13 tropical cyclones of the season, six existed simultaneously. The season was average with 11 tropical storms, five of which strengthened into hurricanes. Further, two of those five intensified into major hurricanes, which are Category 3 or higher on the Saffir–Simpson hurricane wind scale.
The 1940 Nova Scotia hurricane swept through areas of Atlantic Canada in mid-September 1940. The fifth tropical cyclone and fourth hurricane of the year, it formed as a tropical depression east of the Lesser Antilles on September 7, though at the time weather observations in the area were sparse, so its formation was inferred. The disturbance gradually intensified throughout much of its early formative stages, attaining tropical storm strength on September 10; further strengthening into a hurricane north of Puerto Rico occurred two days later. Shortly thereafter, the hurricane recurved northward, and reached peak intensity the following day as a Category 2 hurricane with maximum sustained winds of 100 mph (160 km/h) and a minimum barometric pressure of at least 988 mbar. The cyclone steadily weakened thereafter before making landfall on Nova Scotia on September 17 with winds of 85 mph (135 km/h). Moving into the Gulf of Saint Lawrence later that day, the storm transitioned into an extratropical cyclone. The remnant system curved eastward and passed over Newfoundland before dissipating over the Atlantic on September 19.
The 1926 Nova Scotia hurricane was one of the deadliest Canadian hurricanes in the 20th century. The second tropical cyclone and second hurricane of the season, the storm developed from a trough situated well east of the Leeward Islands on July 29. Over the next few days, it moved west-northwest, becoming a tropical storm by July 31. The cyclone turned to the northwest on August 1 and began strengthening rapidly, reaching hurricane intensity by the early afternoon. The next day, it became a major hurricane—equivalent to Category 3 intensity on the modern-day Saffir–Simpson hurricane wind scale. Over the next few days, the storm's track varied between north-northwest and northwest. Early on August 5, it peaked with winds of 120 mph (190 km/h). The hurricane then began weakening as it curved northward. The storm began losing tropical characteristics while approaching Atlantic Canada, transitioning into an extratropical cyclone on August 8. The remnants soon made landfall near Port Hawkesbury, Nova Scotia, with winds of 75 mph (121 km/h), before being last noted over Newfoundland later that day.
Hurricane Larry was a strong and long-lived Cape Verde hurricane that became the first hurricane to make landfall in Newfoundland since Igor in 2010. The twelfth named storm, fifth hurricane, and third major hurricane of the 2021 Atlantic hurricane season, Larry originated from a tropical wave that emerged off the coast of Africa and organized into a tropical depression on August 31. The next day, the depression developed into a tropical storm, receiving the name Larry. The storm moved quickly across the far eastern tropical Atlantic, where it strengthened into a Category 1 hurricane the morning of September 2. Then, after undergoing a period of rapid intensification, Larry became a major Category 3 hurricane early on September 4. After churning for several days as a strong hurricane in the open ocean, Larry made landfall in Newfoundland on September 11, as a Category 1 hurricane. Later that day, Larry became an extratropical cyclone. Finally, on September 13, Larry was absorbed by a larger extratropical cyclone near Greenland.
