Hurricane Carla

Hurricane Carla was the most intense tropical cyclone landfall in Texas in the 20th century.<ref name=":0">Template:Cite web</ref> The third named storm of the 1961 Atlantic hurricane season, Carla developed from an area of squally weather in the southwestern Caribbean Sea on September 3.<ref name=":0" /> As a tropical depression, it strengthened while heading northwest. The system was upgraded to a tropical storm on September 5 and reached hurricane intensity on September 6. On September 7, Carla entered the Gulf of Mexico, passing northeast of the Yucatán Peninsula. On the morning of September 11, Carla became a category 4 hurricane.<ref>Template:Cite web</ref> Carla made landfall at 2 p.m. on September 11 near Port O'Connor, Texas as a category 4 hurricane with a peak intensity of 145 mph (125 knots). Traveling inland, the storm was reduced to a tropical storm on September 12 and transitioned into an extratropical cyclone on September 13, while centered over southern Oklahoma. Carla's remnants reached the Labrador Sea, Canada and dissipated on September 17, 1961.

While crossing the Yucatán Channel, the outer bands of Carla brought high winds and local flooding in western Cuba and the Yucatán Peninsula. In Texas, wind gusts as high as Template:Convert were observed in Port Lavaca. Tornadoes spawned in the state, including an F4 tornado near Galveston, Texas, resulting in 60 buildings destroyed, eight deaths and 200 injuries.

Throughout the state, Carla destroyed 1,915 homes, 568 farm buildings, and 415 other buildings. Additionally, 50,723 homes, 5,620 farm buildings, and 10,487 other buildings suffered damage. There were 34 fatalities and at least $300 million in losses in Texas. Several tornadoes also touched down in Louisiana, causing the destruction of 140 homes and 11 farms and other buildings, and major damage to 231 additional homes and 11 farm and other buildings. Minor to moderate damage was also reported to 748 homes and 75 farms and other buildings. Six deaths and $25 million in losses in Louisiana were attributed to Carla. Heavy rainfall occurred in several other states, especially in Kansas, where flash flooding severely damaged crops and drowned five people. Overall, Carla resulted in $325.74 million in losses and 43 fatalities.

Meteorological history

Template:Storm path As early as September 1, a tropical disturbance – an area of convective activity – was observed tracking westward across the Caribbean Sea within the Intertropical Convergence Zone (ITCZ). Around that time, an anticyclone was situated over the western Caribbean Sea at the upper-tropospheric levels. Surface charts indicate that a low-level circulation was developing early on September 3.<ref name="new12">Template:Cite report</ref> Thus, it is estimated that a tropical depression – a tropical cyclone with sustained winds of less than Template:Convert – developed about Template:Convert northwest of Barranquilla, Colombia at 1200 UTC.Template:Atlantic hurricane best track Initially, the center of circulation remained difficult to locate on surface charts due to lack of data. At San Andrés, winds shifted west at about Template:Convert, while barometric pressures dropped to Template:Convert. The Weather Bureau Office in Miami, Florida issued its first bulletin at 1600 UTC on September 4, while the depression was centered about Template:Convert east-southeast of Cabo Gracias a Dios, Nicaragua.<ref name="new12"/>

It is estimated that sustained winds reached Template:Convert at 1200 UTC on September 5,<ref name="new13">Template:Cite report</ref> thus the depression strengthened into a tropical storm and was named Carla, while located just northeast of Cabo Gracias a Dios.Template:Atlantic hurricane best track A reconnaissance aircraft flight reported that Carla was continuing to intensify, with surface winds of Template:Convert. Radars reported an unusually large tropical cyclone, with convective bands extending about Template:Convert outward from the center. Around 0000 UTC on September 6, Carla passed near Swan Island, which reported a barometric pressure of about Template:Convert and wind gusts of Template:Convert from the southwest.<ref name="new13"/> Based on observations obtained by a reconnaissance aircraft at 1100 UTC on September 6 – namely a barometric pressure of Template:Convert – a bulletin issued by the Weather Bureau an hour later indicated that the storm had "probably reached hurricane intensity".<ref name="new14">Template:Cite report</ref> According to post-season analysis, Carla reached hurricane status at that time.Template:Atlantic hurricane best track

Shortly after becoming a hurricane on September 6, Carla curved northward in the northwestern Caribbean Sea. At 1200 UTC on September 7, the storm intensified into a Category 2 hurricane while located east-northeast of Cozumel, Quintana Roo, Mexico (actual use of the Saffir-Simpson Hurricane Wind Scale, which was developed in 1971, was not in effect). Shortly thereafter, Carla crossed the Yucatán Channel and entered the Gulf of Mexico. A strong high-pressure area forced Carla to resume its original northwesterly course. Early on September 8, the storm strengthened into a Category 3 hurricane while located just north of the Yucatán Peninsula. Thus, Carla was the third major hurricane of the season. Carla was upgraded to a Category 4 hurricane early on September 10, while approaching the Gulf Coast of the United States. Operationally, at 0000 UTC on September 11, Carla strengthened into a Category 5 hurricane while located in the northwestern Gulf of Mexico. Six hours later, the storm reached its maximum sustained wind speed of Template:Convert.Template:Atlantic hurricane best track However, a 2018 reanalysis concluded that Carla did not reach Category 5 intensity, and in fact only had maximum sustained winds of Template:Convert, and this has been officially incorporated into HURDAT.<ref>Template:Cite journal</ref>

Late on September 11, Carla reached its minimum barometric pressure of Template:Convert. Later that day, the storm struck Matagorda Island, Texas (seven miles south of Port O'Connor) with winds of Template:Convert. Carla rapidly weakened inland, and degenerated to a Category 2 hurricane on September 12, while passing just east of Port Lavaca. Six hours later, the storm was downgraded to a Category 1 hurricane near Shiner, shortly before being downgraded to a tropical storm between Taylor and Coupland. Beginning late on September 12, the storm curved just east of due north. After reaching Oklahoma early on September 13, Carla transitioned into an extratropical cyclone while located over rural Johnston County. The extratropical remnants of Carla moved rapidly northeastward and brought heavy rainfall to some areas of the Great Plains and Midwestern United States. By September 14, it entered Canada near Sault Ste. Marie, Ontario. It then continued swiftly northeastward across Ontario, Quebec, and Labrador, before the remnants dissipated over the Labrador Sea on September 17.Template:Atlantic hurricane best track

Preparations

Occurring a year after Hurricane Donna, officials in the Florida Keys took precautions to brace for potential impact from the storm. The United States Navy flew their planes out of Key West, while Coast Guardsmen evacuated Alligator Reef Light, American Shoal Light, and Sombrero Key Light. Ships docked at Key West sailed out to sea to ride out the squalls. On the morning of September 7, a hurricane watch was issued from the entire coast of Louisiana eastward to Apalachicola, Florida.<ref>Template:Cite report</ref> On September 8, a hurricane watch was issued along the southwest coast of the state from Vermilion Bay westward.<ref>Template:Cite report</ref> It was later extended westward to include the entire coast of Texas, and eastward to Apalachicola, Florida.<ref>Template:Cite web</ref> A portion of the hurricane watch from Aransas Pass, Texas to Grand Isle, Louisiana was upgraded to a hurricane warning at 1600 UTC on September 9.<ref>Template:Cite report</ref> An estimated 500,000 people fled the coasts of Texas and Louisiana, making it the largest evacuation in the history of the United States, at the time.<ref name="new03">Template:Cite report</ref> Further, at least half of those people were from Texas. In small towns along the coast of Texas, 90–100% of their populations evacuated, while 20% of people left the larger cities. Many in Galveston stayed due to protection from the Galveston Seawall.<ref name="pshaus1"/>

Impact

Carla spawned 21 tornadoes, the largest hurricane-related tornado outbreak on record at the time.<ref>Template:Cite webTemplate:Dead link</ref> However, it was overwhelmingly surpassed by Hurricane Beulah in 1967, which spawned at least 120 tornadoes.<ref name="beulah">Template:Cite report</ref> Throughout its path, 43 fatalities and about $325.74 million in damage were attributed to Carla. Most of the impact occurred in Texas, where the storm made landfall as a large and strong Category 4 hurricane.<ref name="stormdata961">Template:Cite reportTemplate:Dead link</ref><ref name="stormdata1261"/><ref name="tcr2"/>

Abnormally high tides and storm surge was reported along the coast of Texas, reaching at least Template:Convert above mean sea level at many coastal areas between Sabine Pass and Port Aransas. The highest tide reported was Template:Convert at Port Lavaca, with large wave heights including Template:Convert in Matagorda, Template:Convert in Port Aransas, Template:Convert in Freeport, Template:Convert in Texas City, and Template:Convert in Galveston and Sabine. Because the storm was a Category 4 hurricane at landfall, Carla produced strong winds, especially near its path. The strongest sustained winds include Template:Convert in Matagorda, Template:Convert in Victoria, and Template:Convert. Additionally, the highest wind gust observations include Template:Convert in Port Lavaca, Template:Convert in Matagorda, and Template:Convert in Aransas Pass, Austwell, Edna, Port Aransas, and Victoria. Carla produced heavy rainfall in Texas, peaking at Template:Convert in Bay City. Other significant precipitation totals include Template:Convert at Scholes International Airport at Galveston, Template:Convert in Downtown Galveston, Template:Convert in Wharton, Template:Convert in Liberty, Template:Convert in Dickinson, Template:Convert in Flatonia, Template:Convert in Columbus, Template:Convert in Hallettsville, and Template:Convert in Smithville.<ref name="pshaus1">Template:Cite report</ref>

Tidal flooding caused by Hurricane Carla

The most significant property damage occurred between Port Arthur and Corpus Christi. Port O'Connor, lying nearest to the location of Carla's landfall, was virtually destroyed. In Columbus, the "Ranch Drive-In" theater is destroyed by the storm and was never reopened after 6 years of operation. In Victoria, the highest sustained wind speed was Template:Convert, while gusts reached Template:Convert. About 4,260 homes were damaged, with around 500 severely damaged or destroyed. 43 businesses and 26 public buildings were also significantly impacted. Damage in the city of Victoria reached $10 million.<ref>Template:Cite report</ref> Of the 21 tornadoes spawned by Carla, eight of them in Texas caused significant impact. On September 11, an F2 tornado near Bay City destroyed two radio towers and damaged several buildings. An F3 tornado injured three people and caused the destruction of one house and impacted three others in Jacksonville, resulting in $25,000 in damage. Another F3 tornado in Channelview, located east of Houston, injured 22 people, destroyed 18 homes and six commercial buildings, damaged 40 additional homes, and caused $200,000 in damage. In the early morning of September 12, a violent F4 tornado moved across Galveston Island along a 1-mile long, 100-yard-wide path (it crossed into Galveston Bay as well), severely damaging 200 buildings, of which 60-75 were destroyed,<ref>Template:Cite web</ref> and causing eight deaths and 200 injuries. This was the first of only two known violent tornadoes ever spawned by a hurricane with the other one happening during Hurricane Hilda in 1964. A few hours later, an F3 tornado in the area destroyed six houses and extensive, but lesser, damage. In Hardin, another F3 tornado damaged six homes. Several structures sustained impact during yet another F3 tornado in Fulbright. The final tornado occurred during the late afternoon of September 13 in Latex. It caused F2 damage, two injuries, and resulted in $2,500 in losses after damaging two houses and three garages.<ref name="StormData">Template:Cite web</ref>

Then little-known newsman Dan Rather reported live from the weather bureau building in Galveston<ref>Template:Cite web</ref><ref>Template:Cite web</ref> during the storm, live on-site storm coverage that would be imitated by later reporters. This marked the first live television broadcast of a hurricane. Rather also alerted the public of the size of Carla in a way that "literally changed the way the world sees hurricanes", according to a fellow reporter. Broadcasting live at the Weather Bureau Office in Galveston, Rather asked a meteorologist to outline the Gulf of Mexico on a transparent sheet of plastic. He then held the map over the black and white radar screen, which put the size of Carla into perspective, saying that Carla was the size of the Gulf of Mexico. CBS was so impressed with Rather's work that he was offered the position of correspondent.<ref>Template:Cite news</ref> Throughout Texas, Carla destroyed 1,915 homes, 568 farm buildings, and 415 other buildings. Additionally, 50,723 homes, 5,620 farm buildings, and 10,487 other buildings suffered damage. There were 460 injuries according to the American Red Cross, though the Monthly Weather Review listed a slightly higher number, 465. The storm caused 34 fatalities in Texas. Causes of death include 20 people drowning, eight from tornadoes, four electrocutions, and one heart attack.<ref>Template:Cite report</ref> Overall, damage in the state was "conservatively" estimated at $300 million.<ref name="stormdata961"/> A breakdown of damage indicates $200 million incurred to property and $100 million to crops, mostly from unharvested rice and lesser impact to cotton and citrus.<ref name="stormdata961"/>

Louisiana

In southeastern Louisiana, abnormally high tides lashed the coast, though no beach erosion was reported. Rainfall was heavy, peaking at Template:Convert in Many. Other observed precipitation totals include Template:Convert in Baton Rouge, Template:Convert in Morgan City, Template:Convert in Shreveport, Template:Convert in New Orleans, Template:Convert in Lafayette, Template:Convert in Alexandria, Template:Convert in Jonesboro and West Monroe, and Template:Convert in Lake Charles.<ref name="pshnew">Template:Cite report</ref> In the western portions of Louisiana, sustained winds peaked at Template:Convert and gusts reached Template:Convert. Only minor damage occurred, limited to roofs, glass, and downed tree limbs. Winds caused a local river to reach Template:Convert above flood stage.<ref>Template:Cite report</ref> The 11 tornadoes spawned by Carla in Louisiana destroyed 140 homes and 11 farm and other buildings, while causing major damage to 231 additional homes and 11 farm and other buildings. Additionally, 748 homes and 75 farm and other buildings suffered minor to moderate damage. Six fatalities and 199 injuries occurred, mostly related to the tornadoes. Damage in Louisiana totaled to about $25 million. A breakdown of losses include $6 million to agriculture, $5 million to buildings, $4 million to boats and beach property, $3 million to roads and bridges, $5 million to oil platforms just offshore, and $2 million in miscellaneous damage.<ref name="tcr2">Template:Cite report</ref>

Oklahoma

Rainfall from Carla in the United States

Carla and its remnants brought heavy rainfall and strong winds to portions of Oklahoma. About Template:Convert of rain fell in Grant, Tillman, Washita Counties. Heavier amounts of at least Template:Convert fell in Atoka and Pushmataha County.<ref name="stormdata1261">Template:Cite reportTemplate:Dead link</ref> Precipitation in the state peaked at Template:Convert in Kingfisher.<ref name="tcmidwest"/> More than 140 city blocks were flooded with up to Template:Convert in residential areas of Kingfisher and up to Template:Convert in business areas. 225 homes and buildings in the city suffered water damage. Throughout the state, damage in other areas included 90 homes and buildings in Tulsa, 50 homes each in El Reno and Oklahoma City, and 10 homes in Pawnee. Additionally, water inundation washed out several bridges and highways in northeastern parts of the state, leaving roads impassable. Sustained winds between Template:Convert and gusts up to Template:Convert were recorded in Oklahoma. Winds injured two people due to airborne debris. Winds and rain combined severely disrupted electrical and telephone services and caused $670,000 in damage, with $600,000 to property and $70,000 to crops.<ref name="stormdata1261"/>

Illinois

The storm dropped precipitation amounts of Template:Convert throughout northwestern Illinois, with a peak of Template:Convert in Mount Carroll. Thus, Carla is the second-wettest tropical cyclone in Illinois, behind only Hurricane Audrey in 1957.<ref name="tcmidwest"/> Additionally, up to Template:Convert fell in 24 hours. Severe local flooding occurred, especially in the northern portions of the state. Heavy property and agricultural damage occurred. Streets and basements were reported to have flooded, while bridge approaches and a few small bridges were washed out. Precipitation of Template:Convert in Chicago flooded about 60 viaducts and 1,000 basements. After the Chicago River rose Template:Convert, the lock gate to Lake Michigan was opened to release excess water. However, the abrupt onrush of water resulted in about $75,000 in damage to boats at Wilmette Harbor.<ref name="stormdata961"/><ref name="tcr2"/>

Elsewhere in the United States

Winds in Key West reached Template:Convert, while much of Florida reported rainfall from the outer bands of Carla.<ref>Template:Cite news</ref> In Kansas, Template:Convert of rain in only 6 hours caused flash flooding. With a peak amount of Template:Convert in Haddam, Carla was the rainiest tropical cyclone in Kansas, until being surpassed by Hurricane Paine in 1986 as well as Tropical Storm Frances in 1998.<ref name="tcmidwest">Template:Cite report</ref> Severe crop damage occurred, especially in areas of Chautauqua and Shawnee Counties and to the south of the Kansas River. Many highways were left impassable due to water inundation. A family of 4 drowned after their car was swept off a road near Waverly. A fifth fatality occurred after a car with one occupant was swept into a tributary of the Marmaton River near Fort Scott. The storm persistently produced winds of Template:Convert, causing further agricultural damage.<ref name="stormdata961"/>

In Nebraska, rainfall peaked at Template:Convert in Hubbrell, making Carla the rainiest tropical cyclone in the state.<ref name="tcmidwest"/> Heavy precipitation also fell in Missouri, especially in Brookfield, Lee's Summit, and Pleasant Hill. The maximum rainfall total in Missouri was Template:Convert in Concordia.<ref name="tcmidwest"/> One fatality was reported in Missouri, though the cause of death is unknown. Rainfall in Iowa peaked at Template:Convert near Chariton, making Carla the rainiest tropical cyclone in the state.<ref name="tcmidwest"/> Up to Template:Convert of rain fell in a 12-hour period in the Lower Peninsula of Michigan, mostly between Cheboygan and Grand Rapids.<ref name="stormdata961"/> However, the Weather Prediction Center indicated precipitation amounts of Template:Convert in Boyne Falls. Regardless, Carla is the 2nd wettest tropical cyclone in the history of Michigan, behind Beryl in 2024.<ref name="tcmidwest"/> Despite, the rainfall, flooding in Michigan was relatively minimal, limited to a washed out dam in Traverse City.<ref name="stormdata961"/> Precipitation in Wisconsin reached Template:Convert in Brodhead, causing Carla to rank as the wettest tropical cyclone in the state.<ref name="tcmidwest"/> Precipitation peaks in other states include Template:Convert in Alabama, Template:Convert in Arkansas, Template:Convert in Mississippi,<ref name="tcgulfcoast">Template:Cite report</ref> and Template:Convert in Indiana.<ref name="tcmidwest"/>

Elsewhere

In Cuba, broadcasts reported severe flooding near Pinar del Río, and in Los Colomas and Punta de Cartas. Offshore Honduras on Swan Island, a rainfall amount of Template:Convert was reported along with wind gusts up to Template:Convert. The remnants of Carla brought tropical storm force winds to some areas of Canada. In Ontario, gusty winds caused power outages in the Clarkson–Port Credit area. Electrical services were are disrupted in New Brunswick, due to winds up to Template:Convert in Saint John. Winds of Template:Convert lashed Halifax in Nova Scotia, thus the Halifax Public Gardens closed for threat of falling trees and branches.<ref>Template:Cite report</ref>

Aftermath

Template:See also Shortly after the storm, Vice President Lyndon B. Johnson, a lifelong resident of Texas, toured the devastation in the state and met with officials from 18 different counties, remarking that "as always, Texans are arising to a challenge... We have suffered hurricane, tornado, and floods, but we in Texas are a bold and brave people."<ref>Template:Cite news</ref> After his report to President John F. Kennedy and Congress, $55 million was approved in aid for Texas, though Kennedy later requested an additional $65 million.<ref name="tmn"/> President Kennedy issued a disaster declaration for Texas, allowing all jurisdictions in the state to apply for public assistance.<ref>Template:Cite report</ref> The president also declared 6 parishes in Louisiana a disaster area.<ref name="tmn">Template:Cite news</ref> Helicopters deployed 88 United States Marines to Galveston to patrol devastated areas. A United States Navy task force composed of medical and construction work teams was also sent to the area. Members of the United States National Guard assisted refugees in returning to their homes and worked to prevent looting.<ref>Template:Cite news</ref>

Owing to the hurricane's intensity and destruction, the name Carla was retired after his season, and will never again be used for an Atlantic hurricane.<ref>Template:Cite web</ref> The name was replaced with Carol for the 1965 season.<ref>Template:Cite news</ref>
