1964 Atlantic hurricane season

The 1964 Atlantic hurricane season featured the highest number of U.S.-landfalling hurricanes since 1933.<ref name="ACE"/> The season officially began on June 15, 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 above average, with thirteen named storms, seven hurricanes, and five major hurricanes. The first system, an unnamed tropical storm, developed on June 2, almost two weeks before the official start of the season. Striking Florida on June 6, the storm brought localized flooding to portions of Cuba and the Southeastern United States, leaving about $1 million in damage. The next storm, also unnamed, developed near the end of July; it did not impact land.

The effects of Hurricanes Cleo, Dora, and Isbell combined were devastating to Florida. Cleo also brought destruction to portions of the Caribbean, especially Guadeloupe and Haiti. After moving inland, Cleo brought flooding to states such as Virginia. Overall, the storm caused 220 deaths and about $198.5 million in damage.<ref group="nb">All damage figures are in 1966 USD, unless otherwise noted</ref> Dora lashed much of North Florida and southeastern Georgia with hurricane-force winds, leaving five fatalities and around $280 million in damage. In October, Isbell brought strong winds and several tornadoes to Florida, as well as flooding to Cuba and The Carolinas. Isbell killed seven people and left approximately $30 million in damage.

The strongest tropical cyclone of the season was Hurricane Cleo, a powerful Category 4 hurricane that severely affected areas in the Caribbean, including the Leeward Islands, Haiti, and Cuba. Cleo went on to hit the United States, in the eastern Florida peninsula as a minimal Category 2 hurricane, particularly in Miami, Florida, where the storm brought severe damage to the state alone, and bringing heavy rain, and severe flooding to the Carolinas in the United States East Coast as a tropical storm. The names Cleo, Dora, and Hilda were retired following the season. Collectively, the tropical cyclones resulted in 271 fatalities and approximately $640.63 million in damage.

The first system, an unnamed tropical storm, developed on June 2.Template:Atlantic hurricane best track It struck Florida as a tropical depression and then strengthened into a tropical storm while out at sea. The storm ceased to exist on June 11. Thereafter, the season went dormant for nearly seven weeks, as the next cyclone, another unnamed storm, did not form until July 23. This would be followed by the development of a third unnamed system on July 28. Tropical cyclogenesis increased in August, which had four tropical cyclones, Abby, Brenda, Cleo, and Dora. The strongest storm of the season, Cleo, peaked with maximum sustained winds of Template:Convert and a minimum barometric pressure of Template:Convert. Four additional storms originated in September, including Ethel, Florence, Gladys, and Hilda. Hurricane Isbell was the sole tropical cyclone to form in the month of October. The final system, another unnamed storm, existed developed on November 5 and dissipated on November 10.Template:Atlantic hurricane best track

The season's activity was reflected with an accumulated cyclone energy (ACE) rating of 153.<ref name="ACE">Template:Cite report</ref> 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 Template:Convert, which is tropical storm strength.<ref>Template:Cite report</ref>

Systems

Unnamed June tropical storm

Template:Infobox Hurricane Small A disturbance that moved out of the Intertropical Convergence Zone (ITCZ) developed into a tropical depression to the east of British Honduras (modern day Belize) on June 2.Template:Atlantic hurricane best track<ref name="MWR"/>Template:Rp Moving slowly northward to north-northeastward across the Caribbean Sea and Gulf of Mexico, the depression failed to intensify significantly. Shortly after 12:00 UTC on June 6, it made landfall just south of Cedar Key, Florida, with winds of Template:Convert. Early the following day, the depression emerged into the Atlantic Ocean near Jacksonville and began to strengthen and move northeastward. While located offshore South Carolina on June 7, the system became a tropical storm. Further deepening occurred slowly, with the storm peaking with winds of Template:Convert late on June 9.Template:Atlantic hurricane best track By June 11, it was absorbed by an extratropical low while located about Template:Convert south-southeast of Sable Island in Nova Scotia.<ref name="MWR"/>Template:Rp

The storm brought local flooding to portions of western Cuba and the Southeastern United States.

The hurricane then made landfall near Les Cayes, Haiti, on August 25 at the same intensity.Template:Atlantic hurricane best track The storm re-emerged into the Caribbean hours later as a Category 2 hurricane but weakened to Category 1 intensity around 12:00 UTC. Cleo briefly moved ashore near Cape Cruz, Cuba, with winds of Template:Convert.Template:Atlantic hurricane best track

The cyclone emerged into the Gulf of Guacanayabo, before striking Sancti Spíritus Province as a minimal hurricane early on August 26. Cleo briefly weakened to a tropical storm before emerging into the Atlantic and re-strengthening, becoming a hurricane again at 18:00 UTC. Now moving north-northwestward, the system reached Category 2 intensity early on August 27, hours before striking Miami Beach, Florida, with winds of Template:Convert. The system quickly weakened inland, falling to tropical storm intensity near Port St. Lucie later that day. Cleo briefly re-emerged into the Atlantic off the coast of North Florida, before making another landfall on St. Simons Island, Georgia, early on August 29 with winds of Template:Convert. Cleo weakened to a tropical depression over South Carolina on August 30 but did not dissipate. Thereafter, the cyclone curved northeastward and eventually eastward while crossing the Carolinas and Virginia. Cleo re-intensified into a tropical storm while re-entering the Atlantic near Norfolk, Virginia, on September 1. It moved east-northeastward and became a hurricane again about 24 hours later. Late on September 3, Cleo became a Category 2 hurricane again. The cyclone then to the northeast and lost tropical characteristics, becoming extratropical to the southeast of Newfoundland on September 4. The remnants meandered in the Atlantic until dissipating about halfway between southern Greenland and Ireland on September 10.Template:Atlantic hurricane best track

Thus, it could not be confirmed that either system became a tropical cyclone.<ref name="meta"/>Template:Rp

Storm names

The following list of names was used for named storms that formed in the North Atlantic in 1964. This is the same list used in the 1960 season with the exception of Dora, which replaced Donna.<ref>Template:Cite news</ref> A storm was named Isbell for the first time in 1964.

In addition, the names Ethel, Florence, Isbell, and Winny would be removed but not retired and replaced by Edna, Frances, Ingrid, and Wesley for the 1968 Atlantic hurricane season with no reason cited. <ref>Template:Cite report</ref><ref>Template:Cite news</ref>

Season effects

This is a table of all of the storms that formed in the 1964 Atlantic hurricane season. It includes their name, duration, peak classification and intensities, areas affected, damage, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all of the damage figures are in 1964 USD.
