The 1917 Nueva Gerona hurricane was the most intense tropical cyclone to strike the Florida Panhandle until Hurricane Opal in 1995.
 The eighth tropical cyclone and fourth tropical storm of the season, this system was identified as a tropical storm east of the Lesser Antilles on September 20.
 After crossing the Lesser Antilles, the system entered the Caribbean Sea and achieved hurricane intensity on September 21.
 After becoming a Category 2 hurricane, the storm struck the northern coast of Jamaica on September 23.
 Early on September 25, the cyclone reached Category 4 status and attained maximum sustained winds of 150 mph (240 km/h) soon thereafter.
 Later that day, the hurricane made landfall in eastern Pinar del Río Province, Cuba.
 The system entered the Gulf of Mexico shortly thereafter and weakened slightly.
 Recurving to the northeast, the hurricane briefly threatened Louisiana before turning toward Florida.
 Early on September 29, the hurricane made landfall near Fort Walton Beach, Florida, with winds of 115 mph (185 km/h).
 Once over land, the cyclone rapidly weakened and transitioned into an extratropical cyclone before dissipating on September 30.
Cyclone Bijli (JTWC designation: 01B, also known as Cyclonic Storm Bijli), was the first tropical cyclone to form during the 2009 North Indian Ocean cyclone season.
 Bijli formed from an area of Low Pressure on April 14.
 Later that evening, RSMC New Delhi upgraded the low pressure area to a Depression and designated it as BOB 01.
 The Joint Typhoon Warning Center (JTWC) then issued a Tropical Cyclone Formation Alert for the system and soon after designated it as Tropical Depression 01B.
 On the evening of April 15, both RSMC New Delhi and the JTWC reported that the system had intensified into a tropical storm, with the former naming it Bilji.
 Soon after, Bilji reached its peak intensity as it approached the coast of Bangladesh.
 However, on the morning of April 17, Bijli weakened to a deep depression due to land interaction, before making landfall just south of Chittagong.
 The remnants of Bilji continued to weaken as they tracked across northern Myanmar, before RSMC New Delhi issued their last advisory on April 18.
 The word Bijli refers to lightning in Hindi.
Super Cyclonic Storm Gonu (also simply known as Cyclone Gonu) is the strongest tropical cyclone on record in the Arabian Sea, and is also the strongest named cyclone in the northern Indian Ocean.
 The second named tropical cyclone of the 2007 North Indian Ocean cyclone season, Gonu developed from a persistent area of convection in the eastern Arabian Sea on June 1, 2007.
 With a favorable upper-level environment and warm sea surface temperatures, it rapidly intensified to attain peak winds of 235 km/h (145 mph) on June 4, according to the India Meteorological Department.
 Gonu weakened after encountering dry air and cooler waters, and early on June 6, it made landfall on the easternmost tip of Oman, becoming the strongest tropical cyclone to hit the Arabian Peninsula.
 It then turned northward into the Gulf of Oman, and dissipated on June 7 after making landfall in southern Iran, the first landfall in the country since 1898.
Cyclone Leon–Eline was the longest-lived Indian Ocean tropical cyclone on record, traveling over 11,000 km during its 29‑day duration.
 It formed on February 1, 2000, in the Australian basin as Tropical Cyclone Leon.
 After crossing 90° E, the Météo-France office in Réunion (MFR) began tracking the system as Tropical Storm Eline on February 8.
 Late on February 17, Eline made landfall near Mahanoro, Madagascar, with 10‑minute winds of 165 km/h .
 The storm rapidly weakened over land, but restrengthened in the Mozambique Channel to reach peak 10‑minute winds of 185 km/h .
 On February 22, Eline made landfall about 80 km south of Beira, Mozambique, near peak intensity, and quickly weakened over land.
 The well-defined circulation moved across Southern Africa, finally dissipating over eastern Namibia on February 29.
Severe Tropical Cyclone Larry (RSMC Nadi designation: 15F, JTWC designation: 17P) was a tropical cyclone that made landfall in Australia during the 2005–06 Southern Hemisphere tropical cyclone season.
 Larry originated as a low pressure system over the eastern Coral Sea on 16 March 2006 and was monitored by the Australian Bureau of Meteorology in Brisbane, Australia.
 The low-pressure area formed into a tropical cyclone two days later and quickly strengthened into a Category 5 storm on the Australian tropical cyclone scale.
 Larry made landfall in Far North Queensland close to Innisfail on 20 March 2006 as a Category 4 with wind gusts reaching 240 km/h and dissipated over land soon after.
Severe Tropical Cyclone Esau became the strongest tropical cyclone to affect New Caledonia on record during February and March 1992.
 A shallow tropical depression developed within the monsoon trough during 24 February, about 370  km (230 mi) to the northeast of Port Vila, Vanuatu.
 Over the next day the system gradually developed further as it moved towards the south-west under the influence of a northerly steering flow, before it passed over Pentecost Island in northern Vanuatu during 25 February.
 After passing over Pentecost the system continued to move towards the southwest and passed near the island of Malampa, before the depression turned northwards and executed a small clockwise loop as it passed over the island of Espiritu Santo.
 The system was subsequently named Esau during 26 February, after it had developed into a tropical cyclone.
 Over the next couple of days the system moved south-westwards towards Australia and away from the islands of Vanuatu.
 Esau subsequently executed a second clockwise loop during 28 February, before it peaked as a Category 4 tropical cyclone on both the Australian tropical cyclone intensity scale and the Saffir-Simpson hurricane wind scale.
 After it had peaked the system moved south-eastwards and threatened Southern Vanuatu, before turning southwards and threatening the French overseas territory of New Caledonia.
 Esau made landfall on the French territory during 4 March, as a category 3 severe tropical cyclone before degenerating into an extratropical cyclone during 5 March.
 The systems remnants made landfall on New Zealand's North Island during 8 March, before they were last noted during the next day over the South Pacific Ocean.
Cyclone Leon–Eline in February 2000 was the third-longest tracked tropical cyclone in the South-West Indian Ocean.
 On February 1, a tropical low originated within the monsoon trough to the south of Indonesia, and would eventually become Tropical Cyclone Leon in the Australian basin.
 Moving westward, the storm fluctuated in strength due to changes in the atmosphere, mostly increasing and decreasing wind shear.
 After crossing 90° E, the Météo-France office in Réunion (MFR) began tracking the system as Tropical Storm Eline on February 8.
 The storm continued across the Indian Ocean and intensified greatly as it approached the east coast of Madagascar.
 Late on February 17, Eline made landfall near Mahanoro, with 10‑minute winds of 165 km/h (105 mph).
 The storm rapidly weakened over land, but restrengthened in the Mozambique Channel to reach peak 10‑minute winds of 185 km/h (115 mph).
 On February 22, Eline made landfall about 80 km (50 mi) south of Beira, Mozambique near peak intensity and quickly weakened over land.
 The well-defined circulation moved across southern Africa, finally dissipating over eastern Namibia on February 29.
Tropical Storm Fay was a strong and unusual tropical storm that moved erratically across the state of Florida and the Caribbean Sea.
 The sixth named storm of the 2008 Atlantic hurricane season, Fay formed from a vigorous tropical wave on August 15 over the Dominican Republic.
 It passed over the island of Hispaniola, into the Gulf of Gonâve, across the island of Cuba, and made landfall on the Florida Keys late in the afternoon of August 18 before veering into the Gulf of Mexico.
 It again made landfall near Naples, Florida, in the early hours of August 19 and progressed northeast through the Florida peninsula, emerging into the Atlantic Ocean near Melbourne on August 20.
 Extensive flooding took place in parts of Florida as a result of its slow movement.
 On August 21, it made landfall again near New Smyrna Beach, Florida, moving due west across the Panhandle, crossing Gainesville and Panama City, Florida.
 As it zigzagged from water to land, it became the first storm in recorded history to make landfall in Florida four times.
 Thirty-six deaths were blamed on Fay.
 The storm also resulted in one of the most prolific tropical cyclone related tornado outbreaks on record.
 A total of 81 tornadoes touched down across five states, three of which were rated as EF2.
 Damage from Fay was heavy, estimated at $560 million.
Cyclone Hudah was a powerful and destructive tropical cyclone that affected Southeast Africa in April 2000.
 It was the last in a series of three cyclones that impacted Madagascar during the year.
 Hudah first developed as a disturbance embedded within the monsoon trough on March 22, within the Australian region cyclone basin.
 Moving westward as the result of a strong subtropical ridge to its south, the storm quickly intensified, and reached Category 2 cyclone intensity on March 25 before entering the Southwest Indian cyclone basin.
 For various reasons that remain unknown, the cyclone was only designated a name by the time it had crossed into the area of responsibility of the Regional Specialized Meteorological Center in Réunion.
 Nonetheless, Météo-France (MFR) assigned the name "Hudah" to the cyclone.
 An eye formed, and the storm intensified into a tropical cyclone on March 27 well to the southeast of Diego Garcia.
 On April 1, the MFR upgraded it to a very intense tropical cyclone, estimating peak 10 minute winds of 225 km/h (140 mph).
 By contrast, the Joint Typhoon Warning Center (JTWC) estimated 1 minute winds of 235 km/h (145 mph).
 Cyclone Hudah maintained peak winds until making landfall just southeast of Antalaha, Madagascar on April 2.
 It weakened greatly over land, but re-attained tropical cyclone status on April 5 after moving over the Mozambique Channel.
 Hudah reached 10 minute winds of 160 km/h (100 mph) by the time it made landfall on Mozambique near Pebane, Mozambique, on April 8, and dissipated by the next day.
Chittagong is a major coastal seaport city and financial centre in southeastern Bangladesh.
