The season officially began on June 15, 1946, and lasted until November 15, 1946. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. However, the first storm, developed in the Gulf of Mexico on June 13, while the final system dissipated just offshore Florida on November 3. There were seven tropical storms; three of them attained hurricane status, while none intensified into major hurricanes, which are Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale. This had not occurred since 1940 and would not again until 1968. Operationally, the fifth tropical storm, which existed near the Azores in early October, was not considered a tropical cyclone but was added to HURDAT in 2014. Although every tropical storm impacted land, effects overall were light, with less than $10 million (1946 USD) in damage and no deaths in the United States throughout the season. The season's most intense cyclone was the fourth hurricane. While the storm was moving northeastward offshore the East Coast of the United States, the Norwegian tanker Maril II was destroyed at sea, causing 16 drownings; the incident could not be directly attributed to the hurricane. The second storm brought relatively minor damage to the Cape Fear region of North Carolina after striking the state early in its duration. While an extratropical cyclone, the remnants of the fifth cyclone devastated a few islands of the Azores and left 120 fishermen missing. The Florida hurricane severely damaged sugar cane in western Cuba and caused five deaths in the island nation. Additionally, the storm left $5.2 million in damage in Florida, mostly inflicting citrus crops. The final storm caused several millions of dollars in damage to crops near Lake Okeechobee. __TOC__ Season summary The Atlantic hurricane season officially began on June 16, 1946.Hurricane Season Officially Open But Weather Bureau Set For Winds https://www.newspapers.com/clip/110215090/the-palm-beach-post/ Wilbur Jennings June 16, 1946 Associated Press The Palm Beach Post 2 Miami, Florida Newspapers.com However, tropical cyclogenesis began on June 13, three days before the official start of the season. There was a total of seven tropical storms, slightly below the contemporaneous 20-year average of 8.5 per season. Three of those strengthened into hurricanes, while none reached major hurricane status – Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale – for the first time since 1940 and it was a phenomenon that would not occur again until 1968. One hurricane made landfall in the United States, while the two other storms with winds of at least 74 mph km/h on remained at sea during their strongest intensities. Overall in the United States, the season resulted in less than $10 million in damage and no deaths. Collectively, the storms of the season left at least $5.2 million in damage. The final cyclone of the season dissipated on November 3, 12 days before the official end of the season on November 15, 1946.https://www.newspapers.com/clip/4786952/the_courier_news/ Truman Seeks Seclusion on Florida Trip November 15, 1946 United Press International Courier News 10 March 31, 2016 Key West, Florida Newspapers.com Tropical cyclogenesis began with the development of a tropical storm over the Gulf of Mexico on June 13. The next system formed offshore the Southeastern United States on July 5. Activity then ceased for nearly seven weeks, until August 25, when the third storm originated in the Bay of Campeche. Although September is the climatological peak of hurricane season, there was only one tropical cyclone that strengthened to tropical storm status that month. The season's most intense storm developed on September 12 and later peaked as a Category 2 hurricane with maximum sustained winds of 100 mph km/h on and a lowest known barometric pressure of 975 mbar inHg on. Additionally, a tropical depression briefly existed near Central America. October was the most active month of the season, with three tropical cyclones. The third storm in October, which was the last system of the season, lasted until November 3. The season's activity was reflected with an accumulated cyclone energy (ACE) rating of 20, the lowest total since 1925 and until 1983.Hurricane Research Division May 2015 Atlantic Basin Comparison of Original and Revised HURDAT http://www.aoml.noaa.gov/hrd/hurdat/comparison_table.html Atlantic Oceanographic and Meteorological Laboratory AOML 21 December 2015 ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. It is only calculated for full advisories on tropical systems at or exceeding 39 mph km/h on, which is tropical storm strength.David Levinson August 20, 2008 2005 Atlantic Ocean Tropical Cyclones National Climatic Data Center National Oceanic and Atmospheric Administration March 6, 2012 http://www.ncdc.noaa.gov/oa/climate/research/2005/2005-atlantic-trop-cyclones.html https://web.archive.org/web/20051201033336/http://www.ncdc.noaa.gov/oa/climate/research/2005/2005-atlantic-trop-cyclones.html dead December 1, 2005 Systems Tropical Storm One Atl Tropical Storm One weather map, June 16, 1946.jpg June 13 June 16 35 ≤ 1014 AL01 1946 path.png A disturbance accompanied by a small area of convection developed into a tropical depression about 165 mi km south-southwest of Cape San Blas, Florida, at 12:00 UTC on June 13. Moving slowly northwestward, the depression intensified into a tropical storm early on the next day. The storm did not deepen beyond maximum sustained winds of 40 mph km/h on, while historical weather maps indicated a barometric pressure of 1014 mbar inHg on on June 15, the lowest in relation to the storm. Later that day, the cyclone weakened to a tropical depression offshore Louisiana. The storm made landfall just east of the Louisiana–Texas border on June 16 and rapidly dissipated. It may have remained a tropical depression throughout its lifespan but data was inconclusive. Winds of 36 mph km/h on were observed at Grand Isle, Louisiana, while winds of "gentle to moderate force" occurred in Texas. In December 1946, H. C. Sumner, a meteorologist at the United States Weather Bureau office in Washington, D.C., published a paper, stating this tropical system occurred between June 14-16. A later publication in HURDAT from the National Hurricane Center stated this system started on June 13 rather than June 14. Hurricane Two Atl Hurricane Two weather map, July 8, 1946.jpg July 6 July 9 70 ≤ 1005 AL02 1946 path.png The interaction between a frontal boundary and a tropical wave resulted in the development of an extratropical cyclone on July 5 offshore the Southeastern United States. Throughout the day, the storm acquired tropical characteristics. Around 00:00 UTC on July 6, the system transitioned into a tropical storm while located about 35 mi km on south-southeast of Myrtle Beach, South Carolina. The cyclone moved northeastward and made landfall near Oak Island, North Carolina, around 08:00 UTC with winds of 50 mph km/h on. In the state, Carolina Beach and Wrightsville Beach observed sustained winds of 45 mph km/h on and gusts of 50 - 60 mph km/h on. In the Wilmington area, winds damaged plate-glass windows and caused brief disruptions to electricity and communication services. Further inland, heavy rainfall, including 7.84 in mm on in less than 24 hours in Manteo, resulted in considerable loss to crops, with 15%-20% damaged in some areas. That was the heaviest 24-hour precipitation total recorded in Manteo since observations began in 1905. The storm moved northeastward and reemerged into the Atlantic Ocean near the southern end of Bodie Island early on July 7. Shortly thereafter, the cyclone began strengthening and became a Category 1 hurricane by 12:00 UTC. After slightly further intensification, the hurricane reached peak intensity at 18:00 UTC on July 7 with maximum sustained winds of 80 mph km/h on. It then curved eastward and began losing tropical characteristics. At 00:00 UTC on July 9, the hurricane transitioned into an extratropical cyclone while located about 390 mi km on south-southeast of Cape Sable Island, Nova Scotia. The extratropical remnants gradually curved northeastward and then north-northeastward while slowly weakening. Late on July 10, the extratropical storm dissipated near Cape Race, Newfoundland. Tropical Storm Three Atl Tropical Storm Three weather map, August 26, 1946.jpg August 25 August 26 35 AL03 1946 path.png In late August, a disturbance was monitored moving over the western Caribbean Sea near Great Swan Island. Despite favorable conditions, further development did not occur until after it reached the Bay of Campeche.H.C. Sumner North Atlantic Hurricanes and Tropical Disturbances of 1946 December 1946 Monthly Weather Review National Hurricane Center Library http://www.aoml.noaa.gov/general/lib/lib1/nhclib/mwreviews/1946.pdf Early on August 25, it is estimated that a tropical storm developed after a reconnaissance aircraft flight reported that the system acquired a well-defined circulation. Peaking with maximum sustained winds of 40 mph km/h on, the storm moved quickly west-northwestward and made near Tampico, Tamaulipas, at 19:00 UTC. By early the next day, the cyclone weakened to a tropical depression and dissipated. A wind gust of 60 mph km/h on was observed in Tampico. Tropical depression A tropical wave over the western Caribbean Sea developed into a tropical depression about 40 mi km on north of the Swan Islands on September 9. However, by the following day, historical weather maps no longer indicated its existence. It is uncertain whether the system dissipated or made landfall in Central America. Hurricane Four Atl AL04 1946 path.png September 12 September 15 85 975 Hurricane Four weather map, September 13, 1946.jpg Early on September 12, the northern portion of a tropical wave spawned a tropical storm about 75 mi km on east Andros Island. The storm strengthened while moving northeastward into the northern Bahamas, striking Andros Island later that day with winds of 65 mph km/h on. Late on September 12, the cyclone strengthened into a hurricane before making landfall on South Abaco with winds of 75 mph km/h on. The hurricane intensified further after entering the open Atlantic, becoming on September 13. Shortly thereafter, it peaked with maximum sustained winds of 100 mph km/h on and a minimum barometric pressure of 975 mbar inHg on, both of which were observed during a reconnaissance aircraft flight. The storm accelerated and weakened due to cooler sea surface temperatures, falling to tropical storm status early on September 15. Shortly thereafter, the cyclone became extratropical about 170 mi km on south of Cape Sable Island. The extratropical remnants moved across Newfoundland and the northern Atlantic, until dissipating well north of the Azores on September 17. In the Bahamas, Hope Town observed sustained winds of 65 mph km/h on and stronger gusts, as well as a barometric pressure of 995 mbar inHg on. The Norwegian tanker Maril II sank after splitting in two, drowning sixteen people. However, because the Maril II was over 300 mi km on away from the storm at the time, the incident could not be directly attributed to the hurricane. Some areas of Nova Scotia experienced strong winds, with sustained winds up to 60 mph km/h on observed throughout the province and a gust of 71 mph km/h on recorded at Sable Island. Heavy rain was also reported, with 2.9 in mm on measured in Halifax. High seas during the Royal Nova Scotia Yacht Squadron race "The Hood Cup" forced the yachts to return to port.https://www.ec.gc.ca/hurricane/default.asp?lang=En&n=C88ECF70-1 1946-4 November 17, 2009 Environment Canada March 23, 2016 https://web.archive.org/web/20130703045750/http://www.ec.gc.ca/hurricane/default.asp?lang=En&n=C88ECF70-1 July 3, 2013 live Tropical Storm Five Atl Tropical Storm Five weather map, October 1, 1946.jpg AL05 1946 path.png October 1 October 3 50 ≤ 1004 A low pressure area initially associated with two frontal systems developed into a tropical depression about 560 mi km on southwest of Flores Island in the Azores at 12:00 UTC on October 1.http://www.aoml.noaa.gov/hrd/hurdat/metadata_master.html Documentation of Atlantic Tropical Cyclones Changes in HURDAT Christopher W. Landsea Atlantic Oceanographic and Meteorological Laboratory National Oceanic and Atmospheric Administration January 22, 2016 Miami, Florida etal After six hours, the depression intensified into a tropical storm. It intensified further while moving east-northeastward. On October 2, the system peaked with maximum sustained winds of 60 mph km/h on and a minimum barometric pressure of 1004 mbar inHg on, both of which were observed by ships. The storm then began losing tropical characteristics and merged with a frontal boundary around 12:00 UTC on October 3 while situated about 275 mi km on south-southwest of Pico Island in the Azores. This storm was not included in HURDAT until 2014. Although the system became extratropical, it continued to deepen further, with sustained winds reaching 90 mph km/h on late on October 4. Additionally, it expanded significantly in size, reaching a diameter of about 1,035 mi km on on October 5. Around that time, the storm passed through the Azores near Faial Island, before weakening and dissipating north of the island chain on October 6. Rough seas at Santa Maria Island left 120 fishermen missing, while 12 fishing vessels, 2 tugboats, and several launches were destroyed. Four fishing boats were also missing. Strong wind gusts up to 98 mph km/h on caused "catastrophic" damage on Santa Maria and São Miguel islands. Homes, crops, and pineapple greenhouses were demolished, while communications were knocked out. Additionally, Lajes Field on Terceira Island was "practically destroyed". Hurricane Six 1946 Florida hurricane Atl Florida_hurricane_1946-10-08_weather_map.jpg AL06 1946 path.png October 5 October 9 85 ≤ 977 A disturbance from the Intertropical Convergence Zone developed into a tropical storm late on October 5, while located over the western Caribbean Sea near the Belize–Mexico border. It moved northeastward and strengthened, reaching Category 1 hurricane status the next day. At 04:00 UTC on October 7, the storm made landfall in western Cuba near Boca de Galafre, Pinar del Río Province, with winds of 80 mi/h km/h on. A barometric pressure of 977 mbar inHg on was observed, the lowest in relation to the system. Additionally, a station recorded a wind gust of 112 mph km/h on. Several sugar cane fields were flattened, with millions of tons of the crop destroyed.https://news.google.com/newspapers?id=BTIsAAAAIBAJ&sjid=CssEAAAAIBAJ&pg=6102,3262314&hl=en First Winds Strike Coast as Florida Stands by for Hurricane Lashings Richard C.

After emerging into the Gulf of Mexico on October 7, the storm curved north-northeastward and strengthened to a Category 2, peaking with maximum sustained winds of 100 mph km/h on. After becoming a Category 2 hurricane on October 7, the cyclone weakened to a Category 1 just six hours later. Around 04:00 UTC on the following day, it made another landfall near Bradenton Beach, Florida, with winds of 85 mph km/h on. In Florida, the gusty winds and rainfall produced by the storm inflicted damage mostly on crops. About 2% of the state's total citrus crop was lost, with damage totaling $5 million. Only about $200,000 in property damage occurred, which was mostly due to coastal flooding in cities such as Everglades, Fort Myers, and Punta Gorda. Moving inland, the hurricane weakened to a tropical storm later on October 8. Early on October 9, the system became extratropical over South Carolina. However, the extratropical remnants persisted for several days, moving in a semicircular path over the eastern Atlantic until dissipating well north of Hispaniola on October 14. Tropical Storm Seven Atl Tropical Storm Seven weather map, November 1, 1946.jpg October 31 November 3 40 1002 AL07 1946 path.png A tropical wave developed into a tropical depression late on October 31 over the Bahamas about halfway between Acklins and Little Inagua. The depression strengthened into a tropical storm early on November 1 and moved northwestward, striking several islands, including Acklins, Long Island, Exuma, and Andros. Late on November 1, the storm peaked with maximum sustained winds of 45 mph km/h on and a minimum barometric pressure of 1002 mbar inHg on. The system then made landfall near Lake Worth, Florida, at the same intensity around 22:00 UTC. Early on November 2, the storm weakened to a tropical depression and recurved northeastward over Central Florida. Shortly after reemerging into the Atlantic Ocean near Ponte Vedra Beach early on November 3, the depression dissipated about 45 mi km on east-northeast of Fernandina Beach. Due to the weak nature of the storm, no wind damage occurred. However, flooding occurred around Lake Okeechobee due to rainfall reaching 6 in mm on. Along main highways, several cars stalled, while a number of canals overflowed.https://www.newspapers.com/clip/4466230/the_daily_times/ Florida Storm Rips Bean Crop November 2, 1946 The Times-Reporter International News Service 2 February 28, 2016 Miami, Florida Newspapers.com Between 50%-70% of early fall crops in the area were damaged, with as much as 60% of snap bean crops lost.
