On July 4, 2005, the National Hurricane Center classified a tropical depression near the Windward Islands. This system moved briskly to the west-northwest, becoming Tropical Storm Dennis the following day. Taking advantage of highly favorable environmental factors, such as low wind shear and high sea surface temperatures, Dennis rapidly intensified. By July 6, the system reached hurricane strength as it began traversing the Jamaica Channel. Around 18:00 UTC on July 7, the hurricane passed 30 mi (45 km) northeast of Port Antonio—60 mi (95 km) northeast of Kingston—with maximum sustained winds of 120 mph (195 km/h)—a Category 3 on the Saffir–Simpson hurricane wind scale. The system subsequently struck Cuba as a Category 4 twice before moving over the Gulf of Mexico. It ultimately moved inland over Florida as a Category 3 on July 10 and dissipated over the Great Lakes eight days later.[1]

Late on July 5, the Government of Jamaica issued a hurricane watch for the nation as Dennis intensified over the eastern Caribbean. This was upgraded to a hurricane warning early on July 6. The warning remained in place for 48 hours as the hurricane brushed the island, being discontinued on July 8 as Dennis moved over northern Cuba and no longer posed a direct threat to Jamaica.[1]

Following the issuance of the hurricane warning, Jamaica's National Emergency Operations Center and Parish Emergency Operations Center were activated.[2] At the behest of Jamaica's Office of Disaster Preparedness and Emergency Management, the Caribbean Disaster Emergency Management Agency allocated resources to assist the nation following the passage of Dennis.[3] The Jamaican Red Cross also notified its branches of the storm,[4] placing personnel and volunteers on standby on July 7.[5] The Jamaica Defence Force Coast Guard assisted with evacuations of Pedro Bank and Morant Cays. Shelters prepped for opening by the evening of July 6 and Norman Manley International Airport ceased operations at 04:00 UTC (11:00 p.m. local time) and Sangster International Airport following soon thereafter.[2][6]

By July 7, 30 shelters opened across five parishes,[7] with at least 793 people using their services.[8] Some officials complained that residents refused to evacuate.[9] However, as the storm impacted the island this number dramatically increased to 6,000 people with shelters open in all parishes.[10] Approximately J$25 million (US$405,000) was made available for relief operations through the nation's Disaster Mitigation Programme. An additional J$20 million (US$324,000) was allocated for clearing drains in preparation for heavy rain.[11]

Impact

Hurricane Dennis intensifying between Jamaica and Cuba on July 7

Hurricane Dennis brought torrential rainfall to most of Jamaica, which already experienced above-average rainfall since April,[12] as it brushed the island to the northeast. Many places recorded over 300 mm (12 in) of rain,[1] with the highest totals occurring across the Blue Mountains; accumulations peaked at 24.54 in (623 mm) in Mavis Bank.[1] One-hour rainfall rates reached 2.6 in (65 mm) in this location with a twenty-four hour peak of 19.59 in (497.6 mm). The latter value equates to a 1-in-50 year event for the town and was 1,005% of the 30-year mean. Rainfall in Constant Spring reached 1-in-25 year levels.[12] Sustained winds in Montego Bay peaked at 69 mph (111 km/h), equivalent to a strong tropical storm.[1] Norman Manley International Airport in Kingston observed peak winds of 37 mph (60 km/h) with a gust to 45 mph (72 km/h). These winds downed trees and power lines, leaving roughly 100,000 customers without electricity; however, overall wind damage was minimal. Several homes and business lost their roofs.[12]

Saint Thomas Parish suffered widespread flooding as multiple rivers burst their banks. The first to flood was the Yallahs River.[6] The nearby Mundicot River prompted multiple evacuations in Yallahs while Johnson River flooded much of Seaforth.[13] Evacuations also took place in Bull Bay where graves were unearthered.[8][14] Overflow from tributaries of the Cane River inundated multiple villages, leaving many isolated.[13] One person drowned after being swept away in the Negro River; his body was recovered three days later.[15] Approximately 200 homes in the parish suffered inundation—including several illegally built structures which were destroyed—with residents reporting maximum flood depths of 10 ft (3.0 m). The community of Eight Miles remained under 4 ft (1.2 m) a day after the hurricane's passage. The severity of flooding was blamed on poor building and maintenance of retaining walls along gullies.[14]

Landslides in Portland Parish rendered roads impassible and damaged many homes.[13][16] A bridge spanning the Rio Grande, connecting eastern and western sides of the parish, was severely damaged.[16] The severed connection left 500 people temporarily isolated. Elsewhere along the river, three homes and two stores were swept away.[17] Agriculture sustained significant damage, with effects compounded by the quick succession of Dennis and Emily a week apart.[12] Along the Rio Grande, the entire banana crop was lost.[18] The two storms wrecked 626 ha (1,550 acres) of crops and killed 4,330 livestock, mostly chickens, at a cost of J$250 million (US$4.05 million).[19]

Two homes along the Mamee River in Saint Andrew Parish were swept away while other residents in mountainous areas of the parish were stranded by landslides.[8] Multiple residents became trapped within Gordon Town and hazardous weather hampered their rescue.[13] A bridge in Mahoneyvale was destroyed.[20] During the pre-dawn hours of July 9, the Annotto, Pencar, and Motherford rivers burst their banks in Saint Mary Parish; more than 500 people relocated from their homes in Annotto Bay.[21] Flooding took place across much of Saint Catherine Parish with eight people requiring rescue.[10][22] The Cobrun Gully submerged several homes in Bushy Park.[23] Eastern areas of Clarendon Parish experienced significant flooding, with several communities cut-off or inundated. A sink hole in Halse Hall engulfed 35 homes.[24] An oil tank overflowed due to heavy rain at a Petrojam Refinery in Kingston Harbour resulting in a minor oil spill. Petrojam crews cleaned the spill within a day.[25][26] Some streets in downtown Kingston were flooded.[27] Effects in Trelawny Parish were relatively limited, with J$16 million (US$259,000) in agricultural damage.[28]

In all, an estimated 209,000 people were affected to varying degrees across 121 communities in the nation. Approximately 6,000 households—an estimated 22,000 people—reported need for assistance; the combined effects of Dennis and Emily left 49 homes destroyed and 391 damaged. Associated losses reached J$100 million (US$1.62 million) from Dennis. The agricultural industry sustained extensive losses, with 610 ha (1,500 acres) damaged and nearly 160,000 livestock, primarily chickens, killed.[12] The rapid succession of Dennis and Emily makes differentiating damage between them difficult. Collectively, the two storms wrought J$5.976 billion (US$96.87 million) in damage, primarily stemming from infrastructure,[12] of which at least J$2.128 billion (US$34.5 million) can be attributed to Dennis alone.[29][30]

Aftermath

Distribution of relief supplies began on July 7.[8] Isolated communities across Saint Andrew, Saint Thomas, and Portland Parishes received airlifted aid the following day.[31] Residents in Cascade required evacuation by airlift.[24] A previously defunct railway bridge in Portland Parish, not in use since the 1980s, was repaired and re-opened to enable travel after the Rio Grande bridge was damaged.[32] Residents in the parish were also advised to temporarily boil or bleach water to prevent the spread of waterborne diseases due to contaminated supplies.[33] The Salvation Army assisted with relief efforts.[34] Although the Government of Jamaica indicated it would not request international assistance,[12] the Government of Cuba provided 11 tons of supplies and Venezuela offered support.[25][35] Efforts to repair and restore damaged roadways reached J$405 million (US$6.56 million).[12] The Leader of the Opposition party requested the Jamaican government release J$500 million (US$8.1 million) for immediate relief; however, Prime Minister P. J. Patterson rejected the proposal.[36]

WINDALCO reported a loss of 10,000 tons of aluminum due to flooding. Manufacturing companies reported J$18.3 million (US$296,000) in losses, primarily from suspended operations. The long-term effects of Dennis were limited, with nearly every economic sector returning to normal within a few months. The only exceptions were exports of banana and coffee crops, both of which were still recovering from Hurricane Ivan in 2004. Overall implications to the nation's gross domestic product were negligible, merely flat-lining growth rather than causing decline. However, in combination with the effects of a drought early in 2005, inflation values required adjustment upwards from 9% to 14.3%[12]
