Hurricane Katrina

Hurricane Katrina was a Category 5 hurricane that made landfall on Florida and Louisiana in August 2005, causing catastrophic damage, particularly in the city of New Orleans and the surrounding areas. Subsequent flooding, caused largely as a result of fatal engineering flaws in the flood protection system known as levees around the city of New Orleans, precipitated most of the loss of lives. The storm was the third major hurricane of the record-breaking 2005 Atlantic hurricane season, as well as the fourth-most intense Atlantic hurricane on record to make landfall in the contiguous United States, behind only the 1935 Labor Day hurricane, Hurricane Camille in 1969, and Hurricane Michael in 2018.

Hurricane Harvey

Hurricane Harvey of 2017 is tied with 2005's Hurricane Katrina as the costliest tropical cyclone on record, inflicting $125 billion in damage, primarily from catastrophic rainfall-triggered flooding in the Houston metropolitan area. It was the first major hurricane to make landfall in the United States since Wilma in 2005, ending a record 12-year span in which no hurricanes made landfall at the intensity of a major hurricane throughout the country. In a four-day period, many areas received more than 40 inches (1,000 mm) of rain as the system slowly meandered over eastern Texas and adjacent waters, causing unprecedented flooding. With peak accumulations of 60.58 in (1,539 mm), Harvey was the wettest tropical cyclone on record in the United States. The resulting floods inundated hundreds of thousands of homes which displaced more than 30,000 people and prompted more than 17,000 rescues.

Tropical cyclone

A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane, typhoon, tropical storm, cyclonic storm, tropical depression, and simply cyclone. A hurricane is a tropical cyclone that occurs in the Atlantic Ocean and northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean; while in the south Pacific or Indian Ocean, comparable storms are referred to simply as "tropical cyclones" or "severe cyclonic storms".

Cyclone Fani

Extremely Severe Cyclonic Storm Fani was the strongest tropical cyclone to strike the Indian state of Odisha since Phailin in 2013. The second named storm and the first severe cyclonic storm of the 2019 North Indian Ocean cyclone season, Fani originated from a tropical depression that formed west of Sumatra in the Indian Ocean on 26 April. Vertical wind shear at first hindered the storm's development, but conditions became more favorable on 30 April. Fani rapidly intensified into an extremely severe cyclonic storm and reached its peak intensity on 2 May as a high-end extremely severe cyclonic storm—the equivalent of a high-end Category 4 major hurricane. Fani weakened before making landfall, and its convective structure rapidly degraded thereafter, degenerating into a remnant low on 4 May, and dissipating on the next day.

Hurricane Irma

Hurricane Irma was the strongest observed hurricane in the Atlantic in terms of maximum sustained winds since Wilma. Irma was the first Category 5 hurricane to strike the Leeward Islands on record, followed by Maria two weeks later. The ninth named storm, fourth hurricane, second major hurricane, and first Category 5 hurricane of the 2017 season, Irma caused widespread and catastrophic damage throughout its long lifetime, particularly in the northeastern Caribbean and the Florida Keys. It was also the most intense hurricane to strike the continental United States since Katrina in 2005, the first major hurricane to make landfall in Florida since Wilma in the same year, and the first Category 4 hurricane to strike the state since Charley in 2004. The word Irmageddon was coined soon after the hurricane to describe the damage caused by the hurricane.

1900 Galveston hurricane

The Great Galveston Hurricane, known regionally as the Great Storm of 1900, was the deadliest natural disaster in United States history, one of the deadliest hurricanes to affect Canada, and the fourth-deadliest Atlantic hurricane overall. The hurricane left between 6,000 and 12,000 fatalities in the United States; the number most cited in official reports is 8,000. Most of these deaths occurred in the vicinity of Galveston after storm surge inundated the entire island with 8 to 12 feet of water. In addition to the number killed, every house in the city sustained damage, with at least 3,636 destroyed. Approximately 10,000 people in the city were left homeless, out of a total population of nearly 38,000. The disaster ended the Golden Era of Galveston, as the hurricane alarmed potential investors, who turned to Houston instead. The Gulf of Mexico shoreline of Galveston island was subsequently raised by 17 ft (5.2 m) and a 10 mi (16 km) seawall erected.

Hurricane Sandy

Hurricane Sandy was the deadliest and most destructive hurricane of the 2012 Atlantic hurricane season. Inflicting nearly $70 billion in damage, it was the second-costliest hurricane on record in the United States until surpassed by hurricanes Harvey and Maria in 2017. The eighteenth named storm, tenth hurricane, and second major hurricane of the year, Sandy was a Category 3 storm at its peak intensity when it made landfall in Cuba. While it was a Category 2 hurricane off the coast of the Northeastern United States, the storm became the largest Atlantic hurricane on record. At least 233 people were killed along the path of the storm in eight countries.

Hurricane Maria

Hurricane Maria was a deadly Category 5 hurricane that devastated Dominica, the U.S. Virgin Islands, and Puerto Rico in September 2017. It is regarded as the worst natural disaster in recorded history to affect those islands and was also the deadliest Atlantic hurricane since Mitch in 1998. The tenth-most intense Atlantic hurricane on record and the most intense tropical cyclone worldwide in 2017, Maria was the thirteenth named storm, eighth consecutive hurricane, fourth major hurricane, second Category 5 hurricane, and deadliest storm of the hyperactive 2017 Atlantic hurricane season. At its peak, the hurricane caused catastrophic destruction and numerous fatalities across the northeastern Caribbean, compounding recovery efforts in the areas of the Leeward Islands already struck by Hurricane Irma. Total losses from the hurricane are estimated at upwards of $91.61 billion, mostly in Puerto Rico, ranking it as the third-costliest tropical cyclone on record.

Hurricane Barry

Hurricane Barry was the fourth tropical depression, second hurricane and named storm of the inactive 1983 Atlantic hurricane season. Developing out of a tropical wave on August 23, Barry quickly strengthened off the coast of Florida, reaching an initial peak intensity with winds of 60 mph (95 km/h). However, increased wind shear caused the storm to weaken to a tropical depression before making landfall near Melbourne, Florida, the next morning. Traveling almost due west, the storm regenerated and became a hurricane on August 28. The storm made landfall on the northern Mexican coastline later that day at peak intensity. Rapid weakening followed shortly after and the storm dissipated the next day. The storm had only minor effects in the United States but destroyed hundreds of homes and left over 400 homeless in northern Mexico. Despite the damage, there were no reports of fatalities or injuries.

1991 Perfect Storm

The 1991 Perfect Storm, also known as The No-Name Storm and the Halloween Gale, was a nor'easter that absorbed Hurricane Grace and ultimately evolved back into a small unnamed hurricane late in its life cycle. The initial area of low pressure developed off Atlantic Canada on October 29. Forced southward by a ridge to its north, it reached its peak intensity as a large and powerful cyclone. The storm lashed the east coast of the United States with high waves and coastal flooding before turning to the southwest and weakening. Moving over warmer waters, the system transitioned into a subtropical cyclone before becoming a tropical storm. It executed a loop off the Mid-Atlantic states and turned toward the northeast. On November 1 the system evolved into a full-fledged hurricane with peak winds of 75 miles per hour (120 km/h), although the National Hurricane Center left it unnamed to avoid confusion amid media interest in the predecessor extratropical storm. It later received the name "the Perfect Storm" after a conversation between Boston National Weather Service forecaster Robert Case and author Sebastian Junger. The system was the fourth hurricane and final tropical cyclone in the 1991 Atlantic hurricane season. The tropical system weakened, striking Nova Scotia as a tropical storm before dissipating.

Hurricane Andrew

Hurricane Andrew was a powerful and destructive Category 5 Atlantic hurricane that struck the Bahamas, Florida, and Louisiana in August 1992. It is the most destructive hurricane to ever hit Florida in terms of structures damaged or destroyed, and was the costliest in financial terms until Hurricane Irma surpassed it 25 years later. It was the strongest landfalling hurricane in decades and the costliest hurricane to make landfall anywhere in the United States, until it was surpassed by Katrina in 2005. Andrew caused major damage in the Bahamas and Louisiana, but the greatest impact was felt in South Florida, where the storm made landfall as a Category 5 hurricane, with 1-minute sustained wind speeds as high as 165 mph (266 km/h). Passing directly through the city of Homestead in Dade County, Andrew stripped many homes of all but their concrete foundations. In total, Andrew destroyed more than 63,500 houses, damaged more than 124,000 others, caused $27.3 billion in damage, and left 65 people dead.

Tropical Storm Barry (2007)

Tropical Storm Barry was a rapidly forming tropical cyclone that made landfall on Florida, United States, in early June 2007. The second named storm of the 2007 Atlantic hurricane season, Barry developed from a trough of low pressure in the southeastern Gulf of Mexico on June 1. It tracked rapidly northeastward, reaching peak winds of 60 mph (95 km/h) before weakening and making landfall near Tampa Bay as a tropical depression. Barry quickly lost tropical characteristics after wind shear removed much of the convection, and early on June 3 it completed the transition into an extratropical cyclone. The extratropical remnants tracked up the East Coast of the United States, and were absorbed by a larger extratropical cyclone on June 5.

Typhoon Haiyan

Typhoon Haiyan, known as Super Typhoon Yolanda in the Philippines, was one of the strongest tropical cyclones ever recorded. On making landfall, Haiyan devastated portions of Southeast Asia, particularly the Philippines. It is the deadliest Philippine typhoon on record, killing at least 6,300 people in that country alone. In terms of JTWC-estimated 1-minute sustained winds, Haiyan is tied with Meranti for being the strongest landfalling tropical cyclone on record. In January 2014, bodies were still being found.

Hurricane Rita

Hurricane Rita was the fourth-most intense Atlantic hurricane ever recorded and the most intense tropical cyclone ever observed in the Gulf of Mexico. Part of the record-breaking 2005 Atlantic hurricane season, which included three of the top ten most intense Atlantic hurricanes ever recorded, Rita was the seventeenth named storm, tenth hurricane, and fifth major hurricane of the 2005 season. Rita formed near The Bahamas from a tropical wave on September 18, 2005 that originally developed off the coast of West Africa. It moved westward, and after passing through the Florida Straits, Rita entered an environment of abnormally warm waters. Moving west-northwest, it rapidly intensified to reach peak winds of 180 mph (285 km/h), achieving Category 5 status on September 21st. However, it weakened to a Category 3 hurricane before making landfall in Johnson's Bayou, Louisiana, between Sabine Pass, Texas and Holly Beach, Louisiana, with winds of 115 mph (185 km/h). Rapidly weakening over land, Rita degenerated into a large low-pressure area over the lower Mississippi Valley by September 26th.
