Query: What was the worst hurricane in history?
The Great Galveston hurricane made landfall on September 9, 1900, near Galveston, Texas. It had estimated winds of at landfall, making the cyclone a Category 4 storm on the modern day Saffir–Simpson Hurricane Scale.
The hurricane caused great loss of life, with a death toll of between 6,000 and 12,000 people; the number most cited in official reports is 8,000, giving the storm the third-highest number of deaths or injuries of all Atlantic hurricanes, after the Great Hurricane of 1780 and Hurricane Mitch in 1998. The Galveston Hurricane of 1900 is the deadliest natural disaster to strike the United States. This loss of life can be attributed to the fact that officials for the Weather Bureau in Galveston brushed off the reports because the city had "weathered them all" and they did not realize the threat. The second-deadliest storm to strike the United States, the San Ciriaco hurricane of 1899, caused around 3,400 deaths.
Overall, Andrew caused about $25.3 billion in damage in Florida, making it the costliest hurricane to hit the state at the time. Some estimates in Florida put the damage as high as $32 billion (1992 USD, $  USD). Almost all of the damage in Florida was caused by strong winds. Of the 44 deaths attributed to the storm, 15 were direct fatalities, while 29 were indirectly caused by the storm. It was later noted that if Andrew had been slightly larger or had made landfall a few miles further north, it would have significantly affected Miami and Fort Lauderdale, which would have resulted in an even higher damage and death toll. An analysis by the American Meteorological Society indicated that unlike most hurricanes, wind damage from Andrew was mostly north of the geometric center and occurred primarily on the eastern edge of the storm. Some officials in Florida considered Andrew the worst storm in the state since the Labor Day hurricane in 1935. The storm surge from Andrew caused more than $500 million in losses to boats and buildings. At the height of the storm, more than 1.4 million people lost electricity and another 150,000 were without telephone service. It is estimated that throughout Florida, the storm damaged 101,241 homes and destroyed approximately 63,000 others – the vast majority in Dade County – with about 175,000 people rendered homeless. In addition to homes, the storm damaged or destroyed 82,000 businesses, of farmland, 31 public schools, 59 health facilities/hospitals, 9,500 traffic signals, of power lines, and 3,000 watermains. Approximately 20 million cubic yards (15 million m) of debris left by the storm were disposed of.
Hurricane Andrew was a small tropical cyclone, with winds of extending out only about from its center. Subsequent to peaking in intensity, the hurricane underwent an eyewall replacement cycle, and at 2100 UTC on August 23, Hurricane Andrew struck Eleuthera as a Category 5 hurricane, with winds of . The cyclone weakened further while crossing the Bahama Banks, and at 0100 UTC on August 24, Andrew made landfall on the southern Berry Islands of the Bahamas as a Category 4 hurricane, with winds of . As it crossed over the warm waters of the Gulf Stream in the Straits of Florida, the hurricane rapidly re-intensified, as the eye decreased in size and its eyewall convection deepened. At 0840 UTC on August 24, Andrew struck Elliott Key with winds of and a central pressure of 926 mbar. About 25 minutes after its first Florida landfall, Andrew hit just northeast of Homestead with a slightly lower pressure of 922 mbar. A recording station at the National Hurricane Center recorded a peak gust of , and sustained winds peaked at in Tamiami.
In total, this tornado killed 72 people, all in Alabama. This made it the deadliest single tornado ever to strike the state of Alabama as well as (at the time) the deadliest in the United States since the 1955 Udall, Kansas tornado that killed 80 people. This death toll would go on to be exceeded by the Joplin EF5 tornado less than a month later. Damage from the tornado amounted to $1.29 billion, making this one of the costliest tornadoes in U.S. history. This tornado also had the longest track of any tornado in the outbreak, with its path extending across Northern Alabama and into Tennessee.
BROUSSARD: We have been abandoned by our own country. Hurricane Katrina will go down in history as one of the worst storms ever to hit an American coast. But the aftermath of Hurricane Katrina will go down as one of the worst abandonments of Americans on American soil ever in U.S. history. … Whoever is at the top of this totem pole, that totem pole needs to be chainsawed off and we’ve got to start with some new leadership. It’s not just Katrina that caused all these deaths in New Orleans here. Bureaucracy has committed murder here in the greater New Orleans area and bureaucracy has to stand trial before Congress now...
It is estimated that at least 100 people lost their lives, mostly due to mudslides, including five persons in Havana. However, reports range as high as 700. Initial estimates of the financial damage caused by the storm were in the millions of dollars, including losses of $1 million in Havana, largely from the destruction of Customs House sheds there, which were filled with many valuable goods. Some of these buildings were swept away, and the winds tore the roof off the main warehouse. In the aftermath—while the hurricane was still widely considered to be two separate storms—rumors arose "of the approach of a third storm", although in actuality no additional storms were known to have occurred in the 1910 season.
New Orleans was catastrophically affected by what Raymond B. Seed called "the worst engineering disaster in the world since Chernobyl", when the Federal levee system failed during Hurricane Katrina in 2005. By the time the hurricane approached the city at the end of August 2005, most residents had evacuated. As the hurricane passed through the Gulf Coast region, the city's federal flood protection system failed, resulting in the worst civil engineering disaster in American history. Floodwalls and levees constructed by the United States Army Corps of Engineers failed below design specifications and 80% of the city flooded. Tens of thousands of residents who had remained were rescued or otherwise made their way to shelters of last resort at the Louisiana Superdome or the New Orleans Morial Convention Center. More than 1,500 people were recorded as having died in Louisiana, most in New Orleans, while others remain unaccounted for. Before Hurricane Katrina, the city called for the first mandatory evacuation in its history, to be followed by another mandatory evacuation three years later with Hurricane Gustav.
Only two major hurricanes—storms of Category 3 intensity or higher—formed during the season, the least since the 1997 season, although tied with the 2006 and 2002 seasons. Named storms were active for 33.50 days during the season, the lowest number of active days since the 1994 season. There were only 11.25 days with active hurricanes, the lowest value since the 2002 season. Despite this, the number of days with major hurricanes was above the long-term average. Four named storms made landfall on the U.S. during the year, but damage from those storms totaled to only about $82 million (2007 USD); this was the least damage the U.S. saw from any Atlantic hurricane season since the 1990 season. The season was one of only six Atlantic hurricane seasons to produce two Category 5 equivalent hurricanes, the others being the 1932, 1933, 1961, 2005, and 2017 seasons. The two Category 5 hurricanes, Dean and Felix, both reached Category 5 strength on two separate occasions, and both made landfall at Category 5 intensity, making the 2007 season the first to feature two hurricanes doing each, both of which would not be repeated until 2017. When Hurricane Felix was upgraded to a Category 5 storm on September 2, it became the eighth to form in this basin since 2000. This gave the decade more hurricanes of such strength than any other on record.
The hurricane season officially began on June 1, though the first tropical cyclone developed on May 21. A total of 21 tropical and subtropical cyclones formed, but just 10 of them intensified into nameable storm systems. This was about average compared to the 1950–2000 average of 9.6 named storms. Six of these reached hurricane status, around the 1950–2000 average of 5.9. Furthermore, three storms reached major hurricane status; close to the 1950–2000 average of 2.3. Collectively, the cyclones of this season caused at least 84 deaths and about $101.63 million in damage. The Atlantic hurricane season officially ended on November 30, with the final cyclone becoming extratropical on October 28.
Typhoon Mike was the strongest typhoon to strike the Philippines since Typhoon Irma in November 1981. Mike was also the most severe typhoon to hit the Philippines since Typhoon Ike during September 1984, which killed over 1,000 people. The typhoon destroyed a television broadcast tower, radio towers, electric cables and bridges, which resulted in widespread power outages and several radio stations briefly went off air. Hundreds of villages were also rendered impassable.
In Havana, of rain fell on October 20. A tidal wave overtopped the Malecón – a seawall built in 1900 by Leonard Wood to project the city – causing much of the damage. The seawall instead prevented water from flowing back into the Straits of Florida. Densely-population low-lying sections of the city were inundated, with water reaching several meters high up to three to four streets inland. People in inundated areas were forced to evacuate to emergency shelters. The hurricane's effects destroyed at least 325 buildings and homes in the city. Some gas and oil tanks were destroyed, while the Havana Oil Company elevator was reduced to a mass of twisted steel. The Havana Automobile Company's headquarters suffered severe window damage due to the strong winds. An antenna tower was also blown down by strong winds. Power outages were widespread across other affected regions. At least 58 fatalities occurred in Havana, many of which were caused by people being struck by collapsing walls or flying debris.
Throughout the season, many typhoons made landfall at a higher intensity. Typhoon Saomai was the most powerful typhoon to strike China for over 50 years, as a Category 4 typhoon, responsible for over 400 deaths. Typhoon Shanshan struck Japan and became the costliest typhoon this season with a total damage of about $2.5 billion. The Philippines got hit by a total of six typhoons, which saw the highest number since 1974. All six typhoons were responsible for over 1,000 casualties and several millions of damages. Typhoon Ioke, which formed from the Central Pacific, entered the basin and became the strongest Central Pacific hurricane. Moreover, it was stated that the ratio of intense typhoons was 0.73, which was the highest since 1970.
In a single town, between 2,000 and 5,000 people were killed overnight after a massive flood inundated the area. Fifi brought continuous rainfall to the area for three days, hampering relief efforts in what was the worst disaster in Honduras' history at the time. In nearby Guatemala, an additional 200 people were killed by severe flooding, making Fifi the worst hurricane to impact the country in nearly 20 years. Following the catastrophic damage wrought by the storm, relief agencies from around the world flew in emergency supplies to assist the hundreds of thousands of homeless people. Countries closer to Honduras, such as the United States, set up city donation centers that would send supplies to the country. In efforts to prevent the spread of post-storm diseases, the government allowed the burning of bodies as they were recovered. In a single day, up to 6,000 bodies were burned. Due to the extreme damage and loss of life, the name was retired from the list of Atlantic hurricane names and has not been used since.
Beginning in 1950, the National Hurricane Center named officially recognized tropical storms and hurricanes. The unnamed hurricane was reported to have met all the criteria for a tropical cyclone, but it was purposefully left unnamed. This was done to avoid confusion among the media and the public, who were focusing on the damage from the initial nor'easter, as the hurricane itself was not expected to pose a major threat to land. It was the eighth nameable storm of the 1991 Atlantic hurricane season. Had the system been named instead, it would have received the name "Henri", which was the next name on the 1991 list after Grace.
In the first discussion bulletin, Forecaster Robbie Berg commented that it was the latest-forming tropical cyclone in the North Pacific east of 140°W since Tropical Depression Twenty-Two-E on November 24, 1987, and Kenneth was the latest forming named storm since Winnie in 1983. Kenneth strengthened to a major hurricane on November 22, becoming the latest-forming major hurricane in the eastern north Pacific basin in the satellite era. Kenneth was upgraded to Category 4 a few hours later, becoming the most powerful late-season storm ever recorded in the eastern north Pacific. However, 2015's Hurricane Sandra surpassed both records when it attained major hurricane status much later than Kenneth, being upgraded to a Category 4 on November 26, 2015.
The following names were used for named storms that formed in the North East Pacific in 2011. Names that were not used are marked in gray. This is the same list used in the 2005 season. No names were retired this year, so this list was used again in the 2017 season.
Typhoon Omar of 1992, known in the Philippines as Typhoon Lusing, was the strongest and costliest typhoon to strike Guam since Typhoon Pamela in 1976. The cyclone formed on August 23 from the monsoon trough across the western Pacific Ocean. Moving westward, Omar slowly intensified into a tropical storm, although another tropical cyclone nearby initially impeded further strengthening. After the two storms became more distant, Omar quickly strengthened into a powerful typhoon. On August 28, it made landfall on Guam with winds of 195 km/h (120 mph). The typhoon reached its peak intensity the next day, with estimated 1‑minute winds of 240 km/h (150 mph), making it a "super typhoon" according to the Joint Typhoon Warning Center (JTWC). Omar weakened significantly before striking eastern Taiwan on September 4, proceeding into eastern China the next day and dissipating on September 9.
Around 12:20 a.m. EST on September 10, Hurricane Dora made landfall about north of St. Augustine, Florida, with sustained winds between 115 and 125 mph (185 and 205 km/h). Although estimated to have been a Category 3 at landfall, the highest winds onshore were believed to have been in the Category 2 range. Striking northeastern Florida, Dora became the first tropical cyclone on record to make landfall in the region. Once onshore the storm gradually weakened, losing hurricane status about 24 hours later, and began a gradual turn towards the northeast. During the morning of September 12, Dora became almost stationary over the southern border between Alabama and Georgia. However, the storm rapidly accelerated and re-emerged into the Atlantic Ocean on September 14 near the Outer Banks of North Carolina. Hours after moving over water, the system transitioned into an extratropical cyclone. The remnants of Dora were last mentioned on September 16 off the northeast coast of Newfoundland.
Hurricane Emily was the only major hurricane to develop during the below-average 1987 Atlantic hurricane season. Forming out of a tropical disturbance that moved off the west coast of Africa on September 20, the storm quickly attained hurricane status before undergoing rapid intensification. On September 22, the storm attained its peak intensity with winds of 125 mph (205 km/h) and a barometric pressure of 958 mbar (hPa; 28.29 inHg). The storm weakened slightly to Category 2 status before making landfall in the Dominican Republic. After weakening to a tropical storm, Emily rapidly tracked northeastward through the Atlantic Ocean, undergoing a second phase of rapid intensification before passing directly over Bermuda on September 25. The following day the final public advisory from the National Hurricane Center was issued on the storm as it transitioned into an extratropical cyclone.
This was the strongest earthquake affecting Chile since the magnitude 9.5 1960 Valdivia earthquake (the most energetic earthquake ever measured in the world), and it was the strongest earthquake worldwide since the 2004 Indian Ocean earthquake and until the 2011 Tōhoku earthquake. It is tied with the 1906 Ecuador–Colombia and 1833 Sumatra earthquakes as the sixth strongest earthquake ever measured, approximately 500 times more powerful than the 7.0 M earthquake in Haiti one month prior in January 2010.
The 1940 Pacific typhoon season marked an interruption in meteorological records in both the Philippines and Hong Kong due to the start of World War II. There were 43 reported tropical cyclones, including 27 that attained typhoon status. The first storm was observed in February, and the first typhoon formed two months later, killing three people along Mindanao. Several storms formed in June and July, including reports of a typhoon in the newspapers that killed 52 in South Korea, and another typhoon reported in newspapers that killed one person on Samar after dropping heavy rainfall. The strongest typhoon of the season originated in July and attained a minimum pressure of , as reported by a ship northeast of the Philippines.
Havana sustained major damage from the hurricane, with 50 houses destroyed, and cable operators in Miami, Santiago, and Jamaica were unable to reach telegraph services in the city. The wall of the American legation was blown down. Vedado's sea baths were severely damaged. Havana's streetcar service was temporarily disrupted by the storm. Trees were blown down in the parks of Havana. Twenty people were killed in the city, while in Batabanó, nine people were killed, with many others missing. In Matanzas, the location of the United States' 28th Infantry, tents were destroyed and there was widespread damage. However, nobody was killed or injured in the city. In San Luis, tobacco crops were ruined, and 150 tobacco barns in the Alquízar municipality were destroyed. The sugar crop in Pinar del Río Province survived well during the hurricane. In the La Guria section of Cuba, the banana crops were completely destroyed. Rivers topped their banks throughout the country.
Through all of the changes, the mission of the 40th remained the same. Hurricane Camille, the worst hurricane in the history of the United States, hit the east coast in August 1969. In the first of a series of hurricane relief efforts, the 40th launched aircraft full of supplies for the stricken area. Hurricanes continued to decimate the east coast of the United States, and the 40th continued to respond. Hurricanes David and Frederick in 1979, Hurricane Hugo in 1989, and Hurricane Andrew in 1992 all brought out the 40th on missions of mercy. From 1969 on, the 40th flew humanitarian mission for a litany of disasters. Mud slides in Bogotá, Colombia in September 1970, an earthquake on the border between Peru and Ecuador a month later, floods in Bolivia, and a volcanic eruption in Nicaragua in 1971, floods in Virginia and Pennsylvania in July 1972, and an earthquake in Nicaragua six months later, in 1973 Operation Authentic Assistance, a massive drought and famine relief operation in Mali, an earthquake in Turkey in 1976, blizzards in New York in 1977, and again in Massachusetts in 1979 all proved the squadron's worth as an instrument of humanitarian relief as well as war. This is only a small handful of the many humanitarian relief operations throughout the history of the 40th. To name them all would take far too much space, but this short list illustrates the immeasurable service the squadron has given representing the United States to the world.
The season produced nineteen tropical or subtropical cyclones, of which seven intensified into tropical or subtropical storms; three became hurricanes, but none further intensified into major hurricanes, the first such occurrence since the 1968 season. Despite the inactivity, the 1972 season resulted in one of the worst natural disasters in American history, Hurricane Agnes. Agnes was a weak but large storm that initially made landfall on the Florida Panhandle before moving up the eastern United States. The hurricane killed 122 people and caused $2.1 billion (1972 USD) in damage, mostly due to flooding in Pennsylvania and New York.
At least 300,000 people were evacuated from Gustav's path as 155 mph (250 km/h) winds toppled telephone poles and fruit trees, shattered windows and tore off the tin roofs of homes. Cuban authorities declared that Gustav is the worst hurricane to hit the country in 50 years. Authorities called the storm damage the worst since 1956. The 211 mph (341 km/h) wind gusts registered in the city of Paso Real de San Diego were the highest in Cuba's history, according to the provincial newspaper, the "Guerrillero". Winds were so strong that the weather station instruments broke. Gustav is considered Cuba's worst hurricane in 45 years, the last hurricane that was worse than Gustav for Cuba was Hurricane Flora in 1963, which was the deadliest Cuban storm since the 1932 Cuba Hurricane.
The overall property damage was estimated at $2.98 billion (1988 USD). Earlier estimates put property damage from Gilbert at $2.5 billion but were as high as $10 billion. A final count of Hurricane Gilbert's victims is not possible because many people remained missing in Mexico, but the total confirmed death toll was 433 people. Gilbert was the worst hurricane in the history of Jamaica and the most destructive tropical cyclone on record to strike Mexico. Due to its widespread impact, extensive damage, and extreme loss of life, the name "Gilbert" was retired in the spring of 1989 by the World Meteorological Organization and was the first name to be retired since Hurricane Gloria in 1985. The name will never again be used for another Atlantic hurricane. The name was replaced by "Gordon" during the 1994 Atlantic hurricane season.
