The 1954 Atlantic hurricane season was an above-average Atlantic hurricane season in terms of named storms, with 16 forming. Overall, the season resulted in $751.6 million in damage, the most of any season at the time. The season officially began on June 15, and nine days later the first named storm developed. Hurricane Alice developed in the Gulf of Mexico and moved inland along the Rio Grande, producing significant precipitation and record flooding that killed 55 people. Activity was slow until late August; only Barbara, a minimal tropical storm, developed in July. In the span of two weeks, hurricanes Carol and Edna followed similar paths before both striking New England as major hurricanes. The latter became the costliest hurricane in Maine's history.
In late September, Tropical Storm Gilda killed 29 people after drenching northern Honduras. A tropical depression in early October was captured by a high-altitude photograph on a rocket, thus producing the first large-scale image of a tropical cyclone. The strongest and deadliest hurricane of the season was Hurricane Hazel, which killed thousands in Haiti before striking near the North Carolina/South Carolina border in October. It caused heavy damage in the United States before becoming extratropical and affecting Ontario. Intense rainfall affected Toronto with severe flooding, leaving significant damage. The season officially ended on November 15, although another hurricane named Alice developed on December 30 to the northeast of the Lesser Antilles; it lasted until January 6 of the following year. In total, there were 16 tropical storms, 7 hurricanes, and 3 major hurricanes.
Season summary
The hurricane season officially began on June 15, when the United States Weather Bureau in Miami, Florida, began 24‑hour operations. The agency, under the direction of Grady Norton had access to 43 other weather stations across the Atlantic basin. Norton died during the season from a stroke while tracking Hurricane Hazel. Additionally, a group of Hurricane Hunters planes were put on standby for the season, able to be flown out into storms and collect data. During the season, there were eight named storms, as well as an unnamed hurricane and a tropical depression. The season officially ended on November 15, although an unnamed tropical storm formed a day later. In addition, Tropical Storm Alice developed on December 31, the latest a tropical cyclone has developed in the calendar year.
Cumulatively, tropical cyclones left 193 deaths and $756 million in damage, becoming the costliest hurricane season at the time. The season was one of six to have three major hurricanes strike the country, along with 2005 (which had four), 1893, 1909, 1933, and 2004. Two of the major hurricanes – Carol and Edna – struck New England; this occurred despite an average of only 5–10 New England hurricanes per century. Carol struck Connecticut as a hurricane and left widespread heavy damage. Only ten days later, Edna became the costliest hurricane in Maine's history. The third major hurricane, Hazel, was the strongest hurricane of the season, attaining winds of . Unusually, no tropical cyclones affected Florida.
The season's activity was reflected with a cumulative accumulated cyclone energy (ACE) rating of 111, which is categorized as being "above normal". 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. ACE is only calculated for full advisories on tropical systems at or exceeding or tropical storm strength.
Systems
Tropical Storm One
A broad trough developed over the eastern Gulf of Mexico on May 26. A frontal disturbance formed over Florida along the trough, spawning an area of broad cyclonic turning. After emerging into the western Atlantic Ocean, a closed circulation developed within the system, and it is estimated that a tropical depression formed on May 28 about east of Jacksonville, Florida. Ship observations in the region suggested that the depression intensified into a tropical storm by late on May 28. The system was small, and was not discovered to have been a tropical cyclone until a reanalysis of data in 2015. The storm moved to the northeast ahead of an approaching trough, bypassing the Carolinas to the east; rainfall brushed the coast of North Carolina. On May 29, ship observations suggested peak winds of . On the next day, the storm became associated with a warm front, indicating that it became extratropical to the southeast of New England. Continuing to the northeast, the former storm crossed over the southeastern coast of Newfoundland before being absorbed by another nontropical low to the northwest on May 31.
Tropical Storm Two
A trough formed over southern Florida on June 17. Early the next day, a circulation formed, signaling that a tropical depression also developed over the Everglades. The system moved slowly north-northeastward, emerging into the western Atlantic Ocean at 06:00 UTC on June 20. Shortly thereafter, the depression intensified into a tropical storm, although the structure was broad and asymmetric due to association with a nearby upper-level low, signaling that the system was possibly a subtropical cyclone. Ship reports in the region indicate that the storm continued to intensify. On June 22, the structure became much more symmetrical while passing just off the Outer Banks, bringing winds of to Wilmington, North Carolina. That day, the Hurricane Hunters estimated winds of , and is possible that the storm briefly attained hurricane status. The peak winds were estimated at , due to a pressure reading of . The storm accelerated northeastward due to an approaching cold front. On June 24, the storm became extratropical, and shortly thereafter made landfall along southwestern Nova Scotia. The system dissipated the next day over the northern Gulf of Saint Lawrence.
Hurricane Alice (June)
On June 24, Tropical Storm Alice developed. It rapidly intensified in the western Gulf of Mexico, giving the citizens of southern Texas and northeastern Mexico little time to prepare. By June 25, Alice intensified to hurricane status, reaching peak winds of that day, before making landfall in northeastern Mexico, just south of the Mexico–United States border. The storm progressed inland along the Rio Grande Valley, dissipating on June 27.
In Mexico, Alice left minor damage, and killed one person due to a fallen power line. Across Texas, Alice dropped torrential rainfall, peaking at near Pandale, with most of the rainfall concentrated around the Pecos River. High precipitation accumulations occurred in areas that had seen little rains in three years. This led to significant flooding along the Pecos River that produced "probably the greatest rate of runoff for a watershed of [that] size in the United States", as reported by the International Boundary and Water Commission. Ozona, Texas, sustained the most impact, estimated at $2 million in damage. Downstream, the Rio Grande rose to the highest level since 1865, which flooded seven towns on either side of the border; Eagle Pass, Texas, was flooded with of water. Overall there were at least 55 deaths.
Tropical Storm Four
A dissipating cold front stalled over the southeastern United States from Arkansas to North Carolina on July 9. On the next day, a low pressure area developed along the coast of Georgia. Soon after, the front dissipated, and by 12:00 UTC on July 10, the system developed into a tropical storm. Observations from a coastal lighthouse and a nearby ship indicated that the storm attained peak winds of while moving slowly east-northeastward, just offshore the Carolinas. The storm began weakening on July 13, and dissipated the next day when it was absorbed by a larger extratropical storm that was developing to the north.
Tropical Storm Barbara
On July 27, a tropical depression developed in the northern Gulf of Mexico, about south of Grand Isle, Louisiana. A map of the low pressure areas forming in July 1954 indicated that the system originated near the Mississippi Delta and tracked southward. After forming, the depression tracked northwestward, intensifying into Tropical Storm Barbara early on July 28. Maximum sustained winds reached , although a tanker offshore named the Henry M. Dawes reported wind gusts of . Officials at the United States Weather Bureau posted a storm warning from Cameron to Burrwood, Louisiana, and also advised small craft to remain at port along the entire northern Gulf Coast. Without intensifying further, Barbara made landfall near Vermilion Bay, Louisiana on July 29, dissipating the next day over Texas. The storm dropped heavy rainfall along its path, including over in New Orleans. The rains caused flooding as well as some damage to the rice crop. However, the Monthly Weather Review yearly summary described the precipitation as "far more beneficial than damaging". There was no wind damage.
Hurricane Carol
Carol developed from a tropical wave near the Bahamas on August 25. It quickly intensified as it tracked generally to the north, becoming a hurricane on August 27. Moving parallel to the coastline of the southeastern United States, Carol passed just east of Cape Hatteras with winds estimated at . It intensified further as it accelerated, striking eastern Long Island as Category 3 hurricane. Carol made its final landfall on Old Saybrook, Connecticut, late on August 31. Within a few hours, the hurricane became extratropical over New Hampshire, which later dissipated over Quebec.
In North Carolina, hurricane-force winds left minor damage to houses, estimated around $228,000. Rains from Carol alleviated drought conditions in the Washington, D.C. area. On Long Island, the storm surge flooded the Montauk Highway with of water about a mile across. High winds left 275,000 homes without power, and damage totaled $3 million on the island.
The hurricane moved ashore in Connecticut shortly after high tide, producing a storm surge of from New London eastward. The surge in Narragansett Bay reached , which surpassed that of the 1938 New England hurricane, which flooded downtown Providence with of water. In New London, rainfall peaked around . The hurricane produced winds of over in Connecticut and Rhode Island, including a record-high gust of at Block Island. Widespread areas were left without power from eastern Connecticut to southern Massachusetts. Further north in Maine, Hurricane Carol downed hundreds of trees, as well as destroying widespread apple groves and corn fields. It became the costliest natural disaster in the state's history, only to be surpassed by Hurricane Edna ten days later. Across New England, the hurricane destroyed about 4,000 homes, 3,500 cars, and 3,000 boats. Damage totaled $460 million, and there were 60 deaths. In neighboring Canada, high rains caused flooding while strong winds downed trees and power lines.
Hurricane Dolly
A tropical wave spawned a tropical depression on August 31 to the northwest of Puerto Rico. It moved rapidly north-northwestward, intensifying into Tropical Storm Dolly later that day and into a hurricane early on September 1. Early in the storm's duration, the U.S. Weather Bureau noted the potential for Dolly to affect the same areas of New England that Hurricane Carol struck just days prior. However, the hurricane turned to the north away from land. The Hurricane Hunters estimated maximum sustained winds of on September 2 after the storm passed about halfway between the Outer Banks and Bermuda. Dolly turned to the northeast on September 2 and became extratropical later that day to the south of Nova Scotia. It was tracked until September 4, until it was last located to the north of the Azores. There was no reported damage.
