Template:Short description Template:Good article Template:Use mdy dates Template:Infobox tropical cyclone season The 1993 Atlantic hurricane season was a deadly, though below average Atlantic hurricane season that produced ten tropical cyclones, eight tropical storms, four hurricanes, and one major hurricane. It officially started on June 1 and ended on November 30, dates which conventionally delimit the period during which most tropical cyclones form in the Atlantic Ocean. The first tropical cyclone, Tropical Depression One, developed on May 31, while the final storm, Tropical Depression Ten, dissipated on September 30, well before the average dissipation date of a season's last tropical cyclone; this represented the earliest end to the hurricane season in ten years.

The most intense hurricane, Emily, was a Category 3 on the Saffir–Simpson Hurricane Scale that paralleled close to the North Carolina coastline causing minor damage and a few deaths before moving out to sea. The most destructive named storm of the season was Hurricane Gert, a tropical cyclone that devastated several countries in Central America and Mexico. Throughout the impact areas, damage totaled to $170 million (1993 USD)<ref group="nb">All damage figures are in 1993 USD, unless otherwise noted</ref> and 102 fatalities were reported. The remnants of Gert reached the Pacific Ocean and was classified as Tropical Depression Fourteen-E.The deadliest system was Tropical Storm Bret, which resulted in 184 deaths, in addition to causing $25 million in losses as it tracked generally westward across Trinidad, Venezuela, Colombia, and Nicaragua. In the Pacific Ocean, the remnants of Bret were attributed to the development of Hurricane Greg. Three other tropical cyclones brought minor to moderate effects on land; they were Tropical Depression One and Tropical Storms Arlene and Cindy. The storms of the 1993 Atlantic hurricane season collectively caused 382 fatalities and $322.3 million in losses.

Season summary

Template:For timeline

{{safesubst:#invoke:Check for unknown parameters|check|unknown=|preview=Page using Template:Center with unknown parameter "_VALUE_"|ignoreblank=y| 1 | style }}

The Atlantic hurricane season officially began on June 1, thus activity began a day early with the development of Tropical Depression One on May 31.<ref name="seasondates">Template:Cite news</ref> It was a below average season in which 10 tropical depressions formed. Eight of the depressions attained tropical storm status, and four of these attained hurricane status. In addition, one tropical cyclone eventually attained major hurricane status, which is below the 1981–2010 average of 2.7 per season.<ref name="background"/> The low amount of activity is attributed to abnormally strong wind shear across the Atlantic basin.<ref name="mwr">Template:Cite web</ref> Only one hurricane and three tropical storms made landfall during the season; Tropical Depression One and Hurricane Emily also caused land impacts. However, the storm collectively caused 382 deaths and $322.3 million in damage.<ref>Template:Cite web

Tropical cyclogenesis in the 1993 Atlantic hurricane season began with the development of Tropical Depression One on May 31.<ref name="seasondates"/> However, in the following two months, minimal activity occurred, with only one named storm, Arlene, in June. August was the most active month, with four systems developing: Tropical Storms Bret, Cindy, and Dennis, as well as Hurricane Emily.<ref name="mwr"/> September, normally the climatological peak of hurricane season,<ref>Template:Cite web</ref> had only three named storms form: Hurricanes Floyd, Gert, and Harvey.<ref name="mwr"/> The final Atlantic tropical cyclone of 1993, Tropical Depression Ten, became extratropical on September 30, two months before the official end of the season on November 30.<ref name="seasondates"/><ref name="10tcr"/>

Overall, the season's activity was reflected with an accumulated cyclone energy (ACE) rating of 39.<ref>Template:Cite web</ref> ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. ACE is only calculated for full advisories on tropical systems at or exceeding Template:Convert or tropical storm strength. Subtropical cyclones are excluded from the total.<ref>Template:Cite web</ref>

Systems

Tropical Depression One

Template:Infobox Hurricane Small Template:Main A westward-moving tropical wave developed into Tropical Depression One near the Isle of Youth on May 31. Due to strong wind shear and its proximity to land, the depression was unable to strengthen and struck western Cuba later that day. It emerged into the Straits of Florida early on June 1 and began to organize and intensify slightly further, but nonetheless remained below tropical storm intensity. Around that time, an approaching shortwave trough accelerated the depression northeastward across the western Bahamas. Thereafter, the wind field of the depression began expanding and lost all tropical characteristics while located northeast of The Bahamas on June 2.<ref name="1tcr1">Template:Cite report</ref>

Heavy rainfall in Cuba caused flooding in the central and eastern portions of the country,<ref name="1tcr1"/> forcing the evacuation of 40,000 people, destroying 1,860 homes and damaging an additional 16,500. Additionally, crops suffered severe impact from the flooding, just two months after significant agricultural damage in Cuba from the Storm of the Century in March.<ref name="reliefweb">Template:Cite report</ref> Overall, the depression left seven fatalities and another five people were listed as missing.<ref name="mh">Template:Cite news</ref> In Haiti, flooding from the outer bands of the storm killed thousands of livestock and resulted in 13 deaths.<ref>Template:Cite news Template:Free access</ref> Heavy precipitation in Florida peaked at nearly Template:Convert, though it caused little impact other than bringing drought relief.<ref>Template:Cite report</ref> Impact, if any in The Bahamas, is unknown.<ref name="1tcr1"/> Template:Clear

Tropical Storm Arlene

Template:Main Template:Infobox Hurricane Small A tropical wave was tracked in the Caribbean Sea beginning on June 9 and subsequently moved across Central America. Eventually, the system entered the Gulf of Mexico, though further development was interrupted by unfavorable wind shear. After conditions became somewhat more favorable, the wave developed into Tropical Depression Two on June 18. The depression slowly strengthened as it tracked west-northwestward and eventually north-northwestward across the western Gulf of Mexico.<ref name="atcr1">Template:Cite report</ref> By June 19, the depression became Tropical Storm Arlene. At 09:00 UTC on the following day, Arlene made landfall on Padre Island, Texas with winds of Template:Convert. The storm quickly weakened inland and degenerated into a remnant low pressure area on June 21.<ref name="atcr2">Template:Cite report</ref>

In El Salvador, rainfall from the precursor tropical wave caused mudslides throughout the country, which in turn resulted in 20 fatalities. Immense amounts of precipitation in Mexico caused flooding in the states of Veracruz, Campeche, Yucatán, San Luis Potosí, Quintana Roo, Nuevo León, and Jalisco. Five deaths and $33 million in damage was reported in Mexico.<ref name="atcr3">Template:Cite report</ref><ref>Template:Cite news</ref> Arlene also dropped torrential rainfall in Texas, peaking at Template:Convert Angleton,<ref>Template:Cite web</ref> while precipitation amounts elsewhere was mainly between Template:Convert. Throughout the state, numerous roads were inundated and more than 650 houses, including 25 mobile homes, suffered water damage.<ref>Template:Cite report</ref> Agriculture losses in eastern Texas include 20% of cantaloupe, 10% of watermelon, and 18% of tomatoes.<ref name="stormdata6">Template:Cite report</ref> One fatality occurred and damage in Texas reached $22 million. Overall, Tropical Storm Arlene caused 26 deaths and $55 million in losses.<ref name="atcr3"/> Template:Clear

Tropical Storm Bret

Template:Main Template:Infobox Hurricane Small A westward-moving tropical wave developed into Tropical Depression Three while located about Template:Convert west of Cape Verde on August 4. The depression strengthened and was upgraded to Tropical Storm Bret on the following day. It strengthened slightly and reached winds of Template:Convert and maintained that intensity until crossing Trinidad on August 7. Later that day, Bret made landfall near Macuro, Venezuela, before briefly re-emerging into the Caribbean Sea. Bret made another landfall in Venezuela on August 8 and crossed northern Colombia.<ref name="Btcr1">Template:Cite report</ref> It weakened over the mountainous terrain and fell to tropical depression intensity over the southwestern Caribbean Sea. Bret re-strengthened to a Template:Convert tropical storm before making landfall in southern Nicaragua on August 10. It crossed into the Pacific Ocean and dissipated, although it later regenerated into Hurricane Greg.<ref name="Btcr2">Template:Cite report</ref>

In Trinidad, winds left 35,000 people without electricity,<ref name=indiana>Template:Cite news Template:Free access</ref> while rainfall caused minor damage to crops and roads, with losses totaling to about $909,000.<ref>Template:Cite report</ref> Rainfall in Venezuela reached Template:Convert in some areas. As a result, widespread mudslides were reported, which in turn destroyed 10,000 houses and caused 173 deaths. One fatality was reported in neighboring Colombia.<ref name="mwr"/> In Nicaragua, the storm destroyed 850 houses and damaged an additional 1,500.<ref name="rwbret">Template:Cite report</ref> Overall, 35,000 people were left homeless in that country.<ref name="mwr"/> In addition, the destruction of 25 medical centers, 10 schools, and 10 churches occurred. Road infrastructure damage was also reported, with 12 bridges collapsing during the passage of Bret.<ref name="rwbret"/> There were 10 fatalities in Nicaragua, 9 of which were drowning victims after a Spanish vessel sank. Overall, Tropical Storm Bret caused 184 deaths and about $25 million in damage.<ref name="mwr"/> Template:Clear

Tropical Storm Cindy

Template:Infobox Hurricane Small Template:Main A tropical wave entered the Atlantic Ocean from northwest Africa on August 8. It traversed the Atlantic and organized into Tropical Depression Four on August 14, while located within Template:Convert to the north of Barbados. After six hours, the depression strengthened into Tropical Storm Cindy, while crossing the island of Martinique. Due to a poor upper-level structure, Cindy barely intensified as it tracked west-northwestward across the eastern Caribbean Sea. Nonetheless, the storm peaked with winds of Template:Convert on August 16. However, interaction with the terrain of Hispaniola caused Cindy to weaken. Late on August 16, the storm had been reduced to a tropical depression, around the time of landfall near Barahona, Dominican Republic. Cindy rapidly weakened inland and dissipated by early on August 17.<ref name="ctcr1">Template:Cite web</ref><ref name="tcr2">Template:Cite web</ref>

The storm dropped torrential rainfall in Martinique, peaking at Template:Convert in Saint-Joseph, which fell in only two hours.

In addition, Cindy left two deaths in the Dominican Republic.<ref name="tcr2"/><ref name="damage">Template:Cite news</ref> Template:Clear

Hurricane Emily

Template:Main Template:Infobox Hurricane Small A tropical wave passed through Cape Verde on August 17. The system moved northwestward and slowly acquired a low-level center of circulation. At 18:00 UTC on August 22, Tropical Depression Five developed while located several hundred miles east-northeast of the Lesser Antilles on August 22. Initially, it headed northwestward while minimal intensification, though by August 25, the depression was upgraded to Tropical Storm Emily. The storm then became nearly stationary while southeast of Bermuda and steadily strengthened during that time. Late on August 26, Emily briefly became a hurricane, though it weakened back to a tropical storm early on the following day. However, by late on August 27, Emily was a hurricane once again. The storm then moved northwestward and maintained Category 1 intensity until becoming a Category 2 hurricane on August 31. By 18:00 UTC, Emily became a Category 3 hurricane while just offshore Cape Hatteras.<ref>Template:Cite report</ref>

However, the storm veered out to sea later on August 29 and weakened, falling to tropical storm intensity while located northeast of Bermuda on September 3. After curving southward and then back to the northeast, Emily weakened to a tropical depression on September 4. The storm lost all tropical characteristics on September 6, while located several hundred miles southeast of Newfoundland.<ref name="etcr2">Template:Cite report</ref> The outer bands of Emily lashed the Outer Banks of North Carolina with heavy rainfall, high tides, and strong winds.<ref name="etcr2"/> The combination of those effects damaged 553 homes beyond repair.<ref name="mwr"/> Sinkholes formed along North Carolina Highway 12 and strong winds uprooted trees, downed power lines, and tore off roofs.<ref name="wp">Template:Cite news</ref> Further north, two fishermen near Nags Head drowned, while a 15-year-old boy also drowned.

Tropical Storm Dennis

Template:Infobox Hurricane Small A tropical wave and its associated low pressure area emerged into the Atlantic from the west coast of Africa on August 21. By the following day, two METEOSAT satellites indicated that the system had a distinct cyclonic rotation and increasing deep convection. At 12:00 UTC on August 23, Tropical Depression Six developed while located about Template:Convert west-southwest of Brava, Cape Verde. Initially, a weak deep-layer mean flow caused the depression to track west-northwest. It is estimated that by 12:00 UTC on August 24, the depression became Tropical Storm Dennis, based on satellite imagery.<ref name="Dtcr1"/>

Early on August 25, Dennis attained its peak intensity with winds of Template:Convert and a minimum barometric pressure of Template:Convert. After peak intensity, a relatively strong mid- to upper-level trough caused Dennis to turn north-northwestward on August 26. Thereafter, an increase in vertical wind shear and a decrease in sea surface temperatures caused the storm to begin weakening. Eventually, the low-level circulation became nearly void of deep convection. On August 27, Dennis was downgraded to a tropical depression. The storm later curved west-southwestward, while located about midway between Bermuda and the southernmost islands of Cape Verde.<ref name="Dtcr1">Template:Cite report</ref> Template:Clear

Hurricane Floyd

Template:Infobox Hurricane Small A tropical wave crossed the west coast of Africa on August 28. Although had it a well-defined low-level circulation, the system was not classified as a tropical cyclone. While tracking west, deep convection diminished and was nearly non-existent by August 31, though the cloud pattern began re-developing on September 3. Eventually, the system curved northwestward and remained well away from the Lesser Antilles. Because a reconnaissance flight into the system indicated a low-level circulation with persistent deep convection, it is estimated that the system became Tropical Depression Seven at 12:00 UTC on September 7, while located about Template:Convert north-northwest of San Juan, Puerto Rico. Only six hours after becoming a tropical cyclone, the depression strengthened into Tropical Storm Floyd. Initially, strong southwesterly wind shear prevented further significant intensification.<ref name="Ftcr1"/>

The storm accelerated north-northwestward after becoming embedded within fast air currents, which was as Floyd moved between a strong trough and a subtropical high pressure area. Later on September 8, the storm passed about Template:Convert west of Bermuda.<ref name="Ftcr1">Template:Cite report</ref> By early on September 9, convection developed along the once exposed low-level circulation. After a buoy reported a two-minute sustained wind speed of Template:Convert and an eye appeared on satellite imagery, Floyd was upgraded to a hurricane at 18:00 UTC on September 9. While accelerating at nearly Template:Convert, the storm began losing tropical characteristics as a result of colder sea surface temperatures and became extratropical at 18:00 UTC on September 10. The remnants of Floyd continued rapidly eastward and struck Brittany, France, at an intensity equivalent to a Category 1 hurricane.<ref name="Ftcr2">Template:Cite report</ref> While passing southeast of Newfoundland, the storm produced light rainfall, peaking at about Template:Convert.<ref>Template:Cite web</ref> Template:Clear

Hurricane Gert

Template:Main Template:Infobox Hurricane Small A tropical wave emerged into the Atlantic Ocean from the west coast of Africa on September 5. The system slowly organize while tracking across the Atlantic Ocean and much of the Caribbean Sea. It developed into a tropical depression while located north of Panama on September 14. On the following day, the depression was upgraded to Tropical Storm Gert before moving ashore in Nicaragua. After weakening to a tropical depression, it proceeded into Honduras<ref name="Gtcr1">Template:Cite report</ref> and reorganized into a tropical storm over the Gulf of Honduras on September 17. Gert made landfall in Belize on the following day and again weakened to a depression while inland. After crossing the Yucatán Peninsula, Gert emerged over warm water in the Bay of Campeche, and strengthened into a Category 2 hurricane on September 20. The hurricane then made landfall on the Gulf Coast of Mexico near Tuxpan, Veracruz, with winds of Template:Convert. Rugged terrain quickly disrupted its structure and Gert entered the Pacific Ocean as a tropical depression from Nayarit on September 21. Five days later, the depression dissipated near Baja California.<ref name="Gtcr2">Template:Cite report</ref>

Because Gert had a broad wind circulation, it produced widespread and heavy rainfall across Central America, which, combined with saturated soil from Tropical Storm Bret a month earlier, caused significant flooding of property and crops. Although hurricane-force winds occurred upon landfall in Mexico, the worst effects in the country were due to flooding and mudslides induced by torrential rain.<ref name="Gtcr3">Template:Cite report</ref> Following the overflow of several rivers,<ref>Template:Cite news Template:Free access</ref><ref>Template:Cite web</ref><ref name=partea>Template:Cite book</ref> deep flood waters submerged extensive parts of Veracruz and Tamaulipas and forced hundreds of thousands to evacuate, including 200,000 in the Tampico area alone.<ref name=mexico>Template:Cite report</ref> The heaviest rainfall occurred further inland over the mountainous region of San Luis Potosí, where as much as Template:Convert of precipitation were measured.<ref>Template:Cite report</ref> In the wake of the disaster, the road networks across the affected countries were severely disrupted and thousands of people became homeless.<ref name=mexico/> Extensive, but less severe flooding occurred in Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua.

Hurricane Harvey

Template:Infobox Hurricane Small A tropical wave passed south of Cape Verde on September 12. By the following day, satellite imagery indicated a cloud system center. The system tracked northwestward across the Atlantic Ocean with slow further development. Due to interaction with an upper-level low on September 18, the system began to significantly organize. After a ship known as ELFS reported winds of Template:Convert, it is estimated that Tropical Depression Nine developed at 18:00 UTC on September 18, while located about Template:Convert south-southeast of Bermuda. The depression initially moved north-northwest, though an approaching short-wave trough eventually caused it to move northeastward.<ref name="Htcr"/>

Convection remained disorganized and the low-level circulation was exposed on September 19. However, by the following day, the depression strengthened into Tropical Storm Harvey. Thereafter, the storm began to rapidly intensify and developed an eye appeared on satellite imagery. While accelerating northeastward, Harvey was upgraded to a hurricane at 18:00 UTC on September 20. However, decreasing sea surface temperatures caused Harvey to immediately weaken back to a tropical storm, while also losing tropical characteristics. At 18:00 UTC on September 21, Harvey transitioned into an extratropical cyclone while located well east of Newfoundland. Six hours later, the extratropical remnants of Harvey were absorbed into a frontal band.<ref name="Htcr">Template:Cite report</ref> Template:Clear

Tropical Depression Ten

Template:Infobox Hurricane Small Tropical Depression Ten developed about Template:Convert southeast of Bermuda at 18:00 UTC on September 29.<ref name="10tcr">Template:Cite report</ref> Initially, convection associated with the depression was confined to north and east of the center.<ref name="10disc1">Template:Cite report</ref> The depression was difficult to track, though wind observations in Bermuda suggested that it passed just north of the island between 0300 and 07:00 UTC on September 30. Although no intensification was predicted, the National Hurricane Center noted that interaction with the approaching cold front could result in baroclinic strengthening.<ref name="10disc2">Template:Cite report</ref> The depression did not organize further and merged with the cold front at 00:00 UTC on October 1.<ref name="10tcr"/> Template:Clear
