Hurricane Humberto was a Category 1 hurricane that formed and intensified faster than any other North Atlantic tropical cyclone on record,before landfall. The eighth named storm and third hurricane of the 2007 Atlantic hurricane season,Humberto developed on September 12,2007,in the northwestern Gulf of Mexico. The tropical cyclone rapidly strengthened and struck High Island,Texas,with winds of about 90 mph (140 km/h) early on September 13. It steadily weakened after moving ashore,and on September 14,Humberto began dissipating over northwestern Georgia as it interacted with an approaching cold front.
Damage was fairly light,estimated at $50 million (2007 USD). Precipitation peaked at 14.13 inches (359 mm),while wind gusts to 85 mph (137 km/h) were reported. The heavy rainfall caused widespread flooding,which damaged or destroyed dozens of homes,and closed several highways. Trees and power lines were downed,knocking out power to hundreds of thousands of customers. The hurricane caused one fatality in the State of Texas. Additionally,as the storm progressed inland,rainfall was reported throughout the Southeast United States.
The origins of Humberto can be traced to the remnants of a frontal trough—the same one that spawned Tropical Storm Gabrielle—that moved offshore of south Florida on September 5. [1] [2] The combination of a weak surface trough and an upper-level low pressure system produced disorganized showers and thunderstorms from western Cuba into the eastern Gulf of Mexico. [3] Tracking slowly west-northwestward, unfavorable wind shear initially inhibited tropical cyclone development. [4]
By late on September 11, environmental conditions became more favorable, [5] and the following morning convection increased over the disturbance. [6] Tracking around the western periphery of a mid-level ridge, the system turned on a slow northwest drift and quickly organized. Radar imagery reported loose banding features, and buoy data indicated the presence of a surface circulation; based on the observations, the National Hurricane Center classified the system as Tropical Depression Nine, while located roughly 60 miles (97 km) southeast of Matagorda, Texas. [7]
Upon becoming a tropical cyclone, the tropical depression was forecast to strengthen slowly to reach peak winds of 45 mph (72 km/h). [7] Within three hours of forming, the depression intensified into Tropical Storm Humberto. [8] A small cyclone, the storm continued to organize quickly as it turned north-northeastward, while radar imagery suggested the formation of an eye by early on September 13. [9] Based on reports from Hurricane Hunters, Humberto was upgraded to a hurricane at 0515 UTC on September 13, while located about 15 miles (24 km) off the coast of Texas. [10] The hurricane made landfall a few miles to the east of High Island at around 0700 UTC. A well-defined eye was maintained with strong convection around it, and Hurricane Hunters reported sustained winds of 85 mph (137 km/h) about two hours after landfall. [11] However, post-storm analysis later determined that the winds were a bit stronger—about 90 mph (140 km/h). [2]
Based on operational estimates of a wind speed increase of 50 mph (80 km/h), the National Hurricane Center reported that "no tropical cyclone in the historic record has ever reached this intensity at a faster rate near landfall." The path of the eye continued northeastward and passed over Port Arthur, Nederland, Port Neches, Groves, and Bridge City, Texas at Category 1 hurricane strength. This was the second time within two years (following Hurricane Rita on September 24, 2005) that these cities experienced a direct hit from a hurricane.
By eight hours after landfall, Humberto weakened to a tropical storm as it crossed into southwestern Louisiana. [12] Increased upper-level wind shear caused the storm to weaken rapidly over land, and late on September 13 Humberto weakened to a tropical depression. Upon issuing its last advisory, the National Hurricane Center remarked on the potential for the remnants of the storm to turn southward into the Gulf of Mexico. [13] However, the storm continued northeastward through the southeastern United States, and on September 14, the storm began dissipating over northwestern Georgia, and shortly thereafter degenerated into a remnant low pressure area. [14]
Upon becoming a tropical cyclone, a tropical storm warning was issued from Port O'Connor, Texas, to Cameron, Louisiana, and a tropical storm watch was posted from Cameron to Intracoastal City, Louisiana; [15] after Humberto became a tropical storm, the watch was upgraded to a warning. [16] Upon reaching hurricane status, the National Hurricane Center issued a hurricane warning from High Island, Texas, to Cameron, Louisiana. [17] An inland tropical storm warning was declared for several parishes in southwestern Louisiana. [18] The National Weather Service Storm Prediction Center posted a tornado watch for southwestern coastal parishes. [12]
Prior to moving ashore, officials in Calcasieu Parish, Louisiana, advised residents in low-lying or flood-prone areas to consider moving to a safer location. A shelter was opened in Lake Charles, [18] where 29 people stayed during the storm. [19] Flood watches and warnings were issued for portions of Mississippi and Louisiana as the storm tracked across the region. [20] Texas Governor Rick Perry, prepared state resources for the potentially impacted areas, including the deployment of 200 Texas Military Forces soldiers and six Black Hawk helicopters and two water rescue teams for search and rescue missions. The Texas State Operations Center was activated shortly after the cyclone developed. [21]
A few hours prior to its development, outer rainbands from the depression began moving over portions of the Texas coast. [6] Heavy rainfall from intense thunderstorms caused minor flooding as they crossed the coastline during the subsequent days; [22] precipitation in the state peaked at 14.13 inches (359 mm) at East Bay Bayou, the highest recorded rainfall total in association with the hurricane. [14] Sustained winds peaked at 69 mph (111 km/h) with gusts to 85 mph (137 km/h) at Sea Rim State Park; the National Weather Service estimates gusts exceeded 90 mph (140 km/h) in southwestern Jefferson County and extreme southeastern Chambers County. [23] In the Golden Pass Ship Channel, an unofficial report of a 115 mph (185 km/h) wind gust was relayed to the National Hurricane Center. [2] Upon moving ashore, Humberto produced a minor storm surge in the state, peaking at 2.86 feet (0.87 m) at Rollover Pass; the combination of surge and waves resulted in light beach erosion. [22]
Hurricane Humberto left 10 homes completely destroyed in Galveston County, with an additional 19 severely damaged in the county; several homes received minor shingle damage, and road closures left about 5,000 houses isolated in the county. The combination of saturated grounds and strong winds uprooted many trees and downed power lines across the path of the hurricane, [22] with at least 50 high voltage transmission poles blown down or seriously damaged; over 120,000 power customers in Orange and Jefferson counties lost power, [19] with 118,000 Entergy customers in the state without electricity. [24] Widespread flooding occurred in Jefferson and Orange counties, and at least 20 homes in Beaumont were flooded. Additionally, several roadways were flooded. The passage of the hurricane caused one fatality in the state; a Bridge City man was killed when his carport crashed on him outside his house. [19] Initially, press reports indicated that the storm wrought up to $500 million in damage; [25] however, final damage estimates were about $50 million. [2]
Oil production was slowed as a result of Humberto, as at least four refineries—the Valero, ExxonMobil, TotalEnergies and Motiva Enterprises LLC plants in Port Arthur—were halted due to the loss of power. Oil prices rose above $80 a barrel in intraday trading on September 12, as a result, ending the next day at a record high of $80.09 a barrel. [26] [27] Natural gas futures rose 8 percent ahead of the storm, but lost most of those gains the next day. [27]
According to the Federal Emergency Management Agency (FEMA), 1,464 residences throughout Texas were affected by Hurricane Humberto. Of these, 25 were destroyed, 96 sustained major damage and 240 sustained minor damage. The cost of individual assistance for those impacted by Humberto would cost $4,776,334; the cost of debris removal and other public assistance amounted to $6,682,074. In terms of per capita income, Jefferson County sustained the most impact, decreasing by $22.38. [28]
Tracking through the state as a weakening tropical storm, Humberto produced light to moderate winds across southwestern Louisiana. Gusts officially peaked at 43 mph (69 km/h) in the state, although an unofficial reading of 55 mph (89 km/h) was reported in Vinton. [23] Heavy rainfall occurred across the area, reaching a peak of 8.25 inches (210 mm) in DeRidder. [29] The rainfall triggered minor river flooding along the Vermilion River in Lafayette. Storm surge was minor in the state, peaking at 2.13 feet (0.65 m) in Cypremont Point; [2] no beach erosion was reported. [19]
Widespread freshwater flooding occurred in Beauregard Parish, leaving homes in DeRidder flooded. High water across the southwestern portion of the state resulted in the closure of several roadways, including U.S. Route 171 and various state highways. Isolated wind damage was reported, particularly near the Texas border, with some trees and power lines blown down. A total of about 13,000 power customers lost electricity in southwestern Louisiana. [19] One EF1 tornado briefly touched down in Vermilion Parish, blowing the roof off one home and downing trees and power lines. [30] Damage throughout Louisiana was estimated at $525,000. [31]
After the circulation dissipated, the remnants of Humberto brought moderate rainfall to the southeastern states and spawned several tornadoes across portions of South Carolina and North Carolina and caused widespread damage in some locations. [32] Heavy rains in Mississippi led to flooding in low-lying areas. In Hinds County, a small rail bridge was washed out, forcing all Amtrak train passengers to take a bus to their destinations. [33] One person was injured after driving his car into a flood. [34] In Alabama, rainfall up to 5.06 in (129 mm) caused minor ponding in low-lying areas but aided in short-term drought relief. [35] In northern Georgia, locally heavy rainfall led to flash flooding, resulting in several road closures. [36] Strong thunderstorms associated with the remnants of Humberto also produced winds up to 51 mph (82 km/h) and penny-sized hail. [37] Throughout North Carolina, seven EF0 tornadoes were confirmed, [38] resulting in minor damage to homes, though none caused injuries or fatalities. [39] Heavy rains associated with the system also triggered flash flooding along some roads, resulting in their closure. [40] In South Carolina, one EF1 tornado touched down in Laurens County, causing moderate damage to several homes before lifting. [41]
Hours after Humberto made landfall, Rick Perry declared Galveston, Jefferson, and Orange counties as disaster areas, which allocated state resources to assist the affected residents. [21] The governor applied for a presidential disaster declaration on September 21. [42] Four Federal Emergency Management Agency (FEMA) teams assessed the hurricane damage in the three most affected counties. [43] Following their assessment, they determined that the damage caused by Humberto was not significant enough to require a disaster declaration. As such, Governor Rick Perry's request from FEMA was denied. [44] Across the Bolivar Peninsula, an estimated 1,500 cubic yards of structural debris and 3,000 cubic yards of tree limbs were needed to be removed in the wake of the storm. [45]
Tropical Storm Allison was a tropical storm that devastated southeast Texas in June of the 2001 Atlantic hurricane season. An arguable example of the "brown ocean effect", Allison lasted unusually long for a June storm, remaining tropical or subtropical for 16 days, most of which was when the storm was over land dumping torrential rainfall. The storm developed from a tropical wave in the northern Gulf of Mexico on June 4, 2001, and struck the upper Texas coast shortly thereafter. It drifted northward through the state, turned back to the south, and re-entered the Gulf of Mexico. The storm continued to the east-northeast, made landfall on Louisiana, then moved across the southeast United States and Mid-Atlantic. Allison was the first storm since Tropical Storm Frances in 1998 to strike the northern Texas coastline.
The 1995 Atlantic hurricane season was a very active Atlantic hurricane season, and is considered to be the start of an ongoing era of high-activity tropical cyclone formation. The season produced twenty-one tropical cyclones, nineteen named storms, as well as eleven hurricanes and five major hurricanes. The season officially began on June 1 and ended on November 30, dates which conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin. The first tropical cyclone, Hurricane Allison, developed on June 2, while the season's final storm, Hurricane Tanya, transitioned into an extratropical cyclone on November 1. The very active Atlantic hurricane activity in 1995 was caused by La Niña conditions, which also influenced an inactive Pacific hurricane season. It was tied with 1887 Atlantic hurricane season with 19 named storms, which was later equalled by the 2010, 2011, and 2012 seasons.
The 2003 Atlantic hurricane season was a very active season with tropical cyclogenesis occurring before and after the official bounds of the season—the first such occurrence since the 1970 season. The season produced 21 tropical cyclones, of which 16 developed into named storms; seven of those attained hurricane status, of which three reached major hurricane status. The strongest hurricane of the season was Hurricane Isabel, which reached Category 5 status on the Saffir–Simpson hurricane scale northeast of the Lesser Antilles; Isabel later struck North Carolina as a Category 2 hurricane, causing $3.6 billion in damage and a total of 51 deaths across the Mid-Atlantic region of the United States.
The 1959 Atlantic hurricane season featured near normal tropical cyclone activity overall. The season officially began on June 15, 1959 and lasted until November 15, 1959. These dates historically described the period in each year when most tropical cyclogenesis occurs in the Atlantic basin. However, the formation of a tropical cyclone is possible at any time of the year, as shown in 1959, by the formation of Tropical Storm Arlene on May 28. Arlene struck Louisiana and brought minor flooding to the Gulf Coast of the United States. The next tropical storm, Beulah, formed in the western Gulf of Mexico and brought negligible impact to Mexico and Texas. Later in June, an unnamed hurricane, caused minor damage in Florida, and then devastated parts of Maritime Canada, resulting in what became known as the Escuminac disaster. Hurricane Cindy brought minor impact to The Carolinas. In late July, Hurricane Debra produced flooding in the state of Texas. Tropical Storm Edith in August and Hurricane Flora in September caused negligible impact on land.
The 1960 Atlantic hurricane season was the least active season since 1952. The season officially began on June 15, and lasted until November 15. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The first system, an unnamed storm, developed in the Bay of Campeche on June 22. It brought severe local flooding to southeastern Texas and was considered the worst disaster in some towns since a Hurricane in 1945. The unnamed storm moved across the United States for almost a week before dissipating on June 29. In July, Hurricane Abby resulted in minor damage in the Leeward Islands, before impacting a few Central American counties — the remnants of the storm would go on to form Hurricane Celeste in the East Pacific. Later that month, Tropical Storm Brenda caused flooding across much of the East Coast of the United States. The next storm, Hurricane Cleo, caused no known impact, despite its close proximity to land.
The 1970 Atlantic hurricane 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 fairly average, with 14 named storms forming, of which seven were hurricanes. Two of those seven became major hurricanes, which are Category 3 or higher on the Saffir–Simpson scale. Also, this was the first season in which reconnaissance aircraft flew into all four quadrants of a tropical cyclone.
The 1985 Atlantic hurricane season had six United States landfalling hurricanes, tied with 1886 and 2020 for the highest number on record. The season officially began on June 1 and lasted until November 30. It was an average season, with 11 named storms developing. This was partially attributed to a La Niña – a meteorological phenomenon that produces favorable conditions across the Atlantic basin, such as lower wind shear and higher sea surface temperatures. The first storm, Ana, developed on July 15 near Bermuda and caused minor effects in Canada while transitioning into an extratropical cyclone. Three other tropical cyclones – Claudette, Henri, and Isabel – did not significantly affect land. Claudette developed offshore of the Southeastern United States and brushed Bermuda and the Azores. Henri and Isabel were dissipating as they approached land. However, the precursor of the latter caused a severe flood in Puerto Rico that killed 180 people. Additionally, Tropical Storm Fabian and three tropical depressions did not have any known impact on land.
The 1989 Atlantic hurricane season was an average hurricane season with 11 named storms. The season officially began on June 1, and ended on November 30. The first tropical cyclone, Tropical Depression One, developed on June 15, and dissipated two days later without any effects on land. Later that month, Tropical Storm Allison caused severe flooding, especially in Texas and Louisiana. Tropical Storm Barry, Tropical Depressions Six, Nine, and Thirteen, and Hurricanes Erin and Felix caused negligible impact. Hurricane Gabrielle and Tropical Storm Iris caused light effects on land, with the former resulting in nine fatalities from rip currents offshore the East Coast of the United States and Atlantic Canada, while the latter produced minor flooding in the United States Virgin Islands.
Hurricane Carla was the most intense tropical cyclone landfall in Texas in the 20th century. 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. 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 when winds reached 130 mph. 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. 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.
Hurricane Cindy was a tropical cyclone that briefly reached minimal hurricane strength in the Gulf of Mexico during July in the 2005 Atlantic hurricane season and made landfall in Louisiana. It was the third named storm and first hurricane of the season. Cindy was originally thought to have been a tropical storm at peak strength, but was upgraded to a Category 1 hurricane in the post-season analysis. Cindy formed on July 3 just east of the Yucatán Peninsula in the Caribbean Sea. The depression soon made landfall on the peninsula and weakened before reemerging in the Gulf of Mexico on July 4. The storm strengthened as it moved north becoming a hurricane just before making landfall near Grand Isle, Louisiana, on July 5. The storm weakened as it moved overland and became extratropical on July 7.
Hurricane Chantal was one of three tropical cyclones to make landfall in Texas during the 1989 Atlantic hurricane season. The third named storm and the first hurricane of the season, Chantal slowly developed on July 30 in the southern Gulf of Mexico from a tropical disturbance that was previously within Intertropical Convergence Zone (ITCZ) while near Trinidad and Tobago. While heading north-northwestward, the depression steadily intensified and was upgraded to Tropical Storm Chantal on the following day. Thereafter, Chantal quickly strengthen and became a hurricane on August 1. After intensifying slightly further, Chantal made landfall near High Island, Texas later that day. The storm quickly weakened upon moving inland and fell to tropical storm intensity a few hours after landfall. Early on August 2, Chantal weakened to a tropical depression and dissipated over Oklahoma by August 4.
Tropical Storm Chris caused minor flooding along the Gulf Coast of the United States in September 1982. The fifth tropical or subtropical cyclone and third named storm of the 1982 Atlantic hurricane season, Chris developed from a surface low-pressure area in the northern Gulf of Mexico on September 9. Although initially displaying subtropical characteristics, the low pressure area gradually acquired tropical characteristics, and was reclassified as Tropical Depression Four within 24 hours of development. The depression then began to intensify and was upgraded to Tropical Storm Chris on September 10. Thereafter, the storm turned north-north-eastward and strengthened further. On September 11, Chris peaked as a 65 mph (100 km/h) tropical storm. Later that day, it made landfall near Sabine Pass, Port Arthur, Texas. By September 13, Chris dissipated over Arkansas.
Tropical Depression Ten was a short-lived tropical cyclone that made landfall on the Florida Panhandle in September 2007. The system developed as a subtropical depression on September 21 in the northeastern Gulf of Mexico from the interaction of a tropical wave, the tail end of a cold front, and an upper-level low. Initially containing a poorly defined circulation and intermittent thunderstorm activity, the system transitioned into a tropical depression after convection increased over the center. Tracking northwestward, the depression moved ashore near Fort Walton Beach early on September 22 and dissipated over southeastern Alabama shortly thereafter.
Hurricane Bonnie caused moderate damage along the Gulf Coast of the United States in late June 1986. The second named storm and first hurricane of the 1986 Atlantic hurricane season, Bonnie developed out of an area of low pressure over the central Gulf of Mexico on June 23. The system gradually intensified and was declared Tropical Storm Bonnie the next day as it moved generally towards the west-northwest. On June 25, Bonnie was upgraded to a hurricane. Bonnie strengthened further and on the following day, the storm attained its peak intensity with maximum sustained winds of 85 mph (137 km/h). Shortly thereafter, Bonnie made landfall near High Island, Texas. Following landfall, Bonnie quickly weakened below tropical storm status and dissipated over Missouri on June 28.
Tropical Storm Candy produced minor impact in the state of Texas during the 1968 Atlantic hurricane season. The third tropical cyclone of the annual season, it developed from a tropical disturbance in the southwestern Gulf of Mexico on June 22. Gradual strengthening occurred, with the depression becoming Tropical Storm Candy on the following day. The storm reached its peak intensity of 70 mph (110 km/h) later that day and made landfall Port Aransas, Texas on June 23. Candy weakened into a tropical depression only hours after moving inland. However, the system remained a designated cyclone until June 26, at which time it completed extratropical transition over the state of Michigan.
