Ураган Эрл (1998): Траектория и последствия

Category 2 Atlantic hurricane in 1998

Hurricane Earl was an atypical, disorganized, and short lived Category 2 hurricane that caused moderate damage throughout the Southeast United States. It formed out of a poorly organized tropical disturbance over the southwest Gulf of Mexico late on August 31, 1998. Tracking towards the northeast, the storm quickly intensified into a hurricane on September 2 and made landfall early the next day near Panama City, Florida. Rapidly tracking towards Atlantic Canada, the extratropical remnants of Earl significantly intensified before passing over Newfoundland on September 6. The remnants were absorbed by former Hurricane Danielle two days later. Moderate beach erosion occurred along the coasts of Louisiana, Mississippi, Alabama, and Florida as waves reached 20 feet (6 m). Throughout Florida, nearly 2,000 homes were damaged and a few were destroyed. Severe flooding caused by storm surge and heavy rains was the main cause of damage in the state. Offshore, two men drowned after their boat capsized during the storm. A minor tornado outbreak took place in relation to Earl in Florida, Georgia, South Carolina, and North Carolina. A tornado in South Carolina killed one person after completely destroying the occupant's home. In all, three people were killed by Earl and damages were $79 million (1998 USD; $104.4 million 2009 USD).

Hurricane Earl originated out of a strong tropical wave that moved off the west coast of Africa on August 17. By August 23, a weak area of low pressure developed within the wave and well developed convective activity was present as it tracked through the Lesser Antilles. Once in the Caribbean, strong wind shear produced by the outflow of Hurricane Bonnie inhibited further development of the system. As it remained well defined, satellites easily followed the low pressure into the Gulf of Mexico. By August 31, the storm had become sufficiently organized for the National Hurricane Center (NHC) to classify it as Tropical Depression Five. At this time, the depression was located roughly halfway between Mérida and Tampico, Mexico. Operationally, the NHC immediately classified the system as Tropical Storm Earl based on a Hurricane Hunter Reconnaissance mission that found flight level winds of , corresponding to surface winds of Due to the existence of multiple circulation centers, the initial movement of the storm was uncertain, but forecasters anticipated a general northward movement. In post season analysis, it was determined that the system intensified into Tropical Storm Earl while located about 575 mile (925 km) south southwest of New Orleans. Initial advisories on Earl relocated the center of circulation several times before focusing on the true circulation center. Remaining disorganized, Earl continued to intensify as the center of circulation was located close to deep convection. The NHC stated in their fifth advisory on the storm that Earl did not appear to be fully tropical due to the lack of organization. Around 1200 UTC on September 2, Earl intensified into a hurricane despite having an atypical structure; the wind field of the storm was asymmetric and the strongest winds were located well to the southeast of the center. The central barometric pressure continued to fall despite the fact that the storm was beginning to weaken. Around 0000 UTC on September 3, the central pressure decreased to ; however, winds also decreased to
Around 0600 UTC (1:00 am EDT) on September 3, Hurricane Earl made landfall near Panama City, Florida with winds of Several hours later, Earl finished its transition and continued to rapidly track through the Southeast United States. After entering the Atlantic Ocean, the remnants of Earl began re intensify due to the effects of a baroclinic zone. Relatively cool sea surface temperatures near Atlantic Canada prevented tropical development; however, during a 36 hour span, Earl rapidly intensified, as the central barometric pressure decreased by 40 mbar (hPa; ) to 957 mbar (hPa; ). An estimated 10,000 workers were evacuated from both onshore and offshore rigs. State parks along the Florida Panhandle were also closed and highways became congested with thousands of residents and tourists evacuating the barrier islands. A state of emergency was declared for portions of southeast Louisiana as tides in relation to the storm were forecast to reach Emergency shelters were opened throughout Plaquemines Parish, schools were closed in many areas, and the floodgates around New Orleans were shut. Throughout the Alabama and Mississippi coasts, schools were closed due to the storm.

Throughout the Southeast United States, Hurricane Earl killed three people and caused $79 million (1998 USD; $104.4 million 2009 USD) in damages.

Ahead of Hurricane Earl's landfall in Florida, several tornadoes were spawned along the outer bands of the storm. The first tornado to touch down was a brief F0 that caused no known damage. The second tornado, rated F1, caused moderate damage to three homes and two buildings that were under construction along its 3 mile (5 km) path. During a 15 minute span, three brief F0 tornadoes touched down in unpopulated areas, causing minor tree damage. Several hours later, a strong F1 tornado touched down in Port Canaveral. The tornado damaged 14 cars, eight condominiums, four businesses, a mobile home, and a fire station. In all, the tornado caused $6 million in damages and injured one person. On St. George Island, an F1 tornado damaged six homes, leaving $150,000 in damages. High waves, estimated at caused a boat to capsize off the coast of Panama City, drowning both occupants. A lighthouse on St. George Island was also destroyed by the storm. At least 50 people were stranded in Alligator Point after floodwaters washed out the main access route to the town. In Wakulla County, 216 homes and businesses were damaged by high winds and flooding. Severe flooding in coastal Taylor County caused significant damage in nine communities. County officials reported that 66 structures were damaged by Earl. Five homes were destroyed and 39 others were damaged by flooding in Dixie County. On September 3, the strongest tornado spawned by Earl in Florida touched down in Citrus County. Rated F2, the tornado tracked for 5 mile (8 km), destroying eight homes and damaging 24 others. Several trees and power lines were also downed. Two people were injured in one of the destroyed homes and damages from the tornado amounted to $500,000. In all, Hurricane Earl killed two people and caused $73 million (1998 USD; $96.5 million 2009 USD) in Florida. Rainfall was relatively light, peaking around in Morgan City, as only the outer bands of Earl affected the state. Only minimal damage resulted from the storm in Louisiana, with monetary losses amounting to $32,000. However, losses due to the large scale evacuation of oil and natural gas rigs was estimated to be several million dollars. In Alabama, Earl produced moderate rainfall, with areas along the Georgia state line receiving more than Despite the center of Earl passing close to the state, winds were only recorded up to , resulting in scattered power outages and downed trees. Portions of Alabama State Route 28 were temporarily shut down due to debris covering the road. In all, damages in the state amounted to $120,000. Ahead of Earl, an onshore flow related to the storm produced swells along the Georgia coast, causing significant damage to marinas. The Mar Lin Marina sustained the most damage from this event; all the docks were destroyed, 30 boats were damaged and six were destroyed. Damages to the marina and boats amounted to $1.3 million. Heavy rains fell throughout central areas of the state, with the highest amounts nearing Because Earl rapidly weakened upon landfall, the highest winds in Georgia only reached Numerous trees and power lines were downed, resulting in scattered power outages. Several streets were flooded due to the rains, resulting in traffic accidents. One tornado was spawned by Earl in Georgia; rated F2 on the Fujita scale, the tornado tracked for 8 mile (13 km) in Screven County. Estimated at in width, the tornado destroyed five mobile homes and a business, severely damaged 15 additional mobile homes and caused some damage to five others. Seven people were injured by the tornado and damages amounted to $435,000. Several major highways were temporarily closed due to high water or debris covering the road. Numerous homes sustained damage from fallen trees in several counties. In all, damages from Earl amounted to $2.3 million in Georgia. Inland, isolated amounts of of rain fell. A brief F1 tornado touched down several hours later, damaging the roof of a barn and uprooting several trees before dissipating. The most damaging tornado spawned by Earl was a wide, F2 tornado that struck the Fairlawn subdivision near Moncks Corner. Along the tornado's 7 mile (11 km) track, 21 homes were destroyed and 73 others were damaged. Nine people sustained injuries due to the tornado and damages amounted to $2.8 million. Still recovering from Hurricane Bonnie, the remnants of Earl produced widespread rain over North Carolina, triggering flooding. In Union County, up to 15 roads were shut down due to flooding, a few cars were also washed off roads at the height of the floods. In Charlotte, several roads were flooded. The Carteret Community College, which was severely damaged by Bonnie, was again damaged by Earl. High winds from the storm damaged temporary protective measures, allowing rain to flood the interior of the building, causing water damage to the structure and materials inside. In front of the Crystal Coast Civic Center, fabriform, installed to stabilize the beach, was damaged by the storm, resulting in significant beach erosion. Two short lived tornadoes touched down in North Carolina from Earl. The first, an F0, damaged at least 15 mobile homes, overturned sheds, destroyed a porch and two campers. No injuries resulted from the tornado and damage amounted to $50,000. The second and stronger of the two tornadoes, rated F1, only touched down for a few seconds; however, it destroyed one home and severely damaged a neighboring home. According to eye witness reports, the tornado lifted the home off the ground before the home broke apart and fell to the ground.

The initial tropical disturbance passed through the Yucatán Peninsula on August 29 and inflow bands to the south of Earl continued rainfall across southeast Mexico until early September 2. The highest rainfall total was reported from Belizario Dominguez/Moto, where of precipitation fell. The extratropical remnants of Earl produced strong winds and heavy rains throughout Newfoundland and Nova Scotia on September 6. Sustained winds were recorded up to and rains totaled between throughout Newfoundland. On Nova Scotia, rainfall peaked at on Cape Breton Island. The highest recorded total on Newfoundland reached in northwestern areas of the island.

On September 4, President Bill Clinton approved disaster declarations for six counties in Florida. Bay, Dixie, Franklin, Gulf, Taylor, and Wakulla counties were approved for Individual Assistance. Residents in the designated counties were eligible to receive federal funding for three months following the storm. By September 8, State Farm had received 200 auto and 720 homeowners claims from the affected region, most of which were partial damage claims. Allstate had received 80 auto and 587 homeowners claims from Florida and 540 claims from Georgia. Additionally, Nationwide reported that up to 1,000 claims had been filed from Florida. Following the impacts of Hurricane Opal in 1995, Earl and later Hurricane Georges, the state of Florida undertook a recovery project to restore the eroded beaches along the Panhandle coast. The United States Military allocated $2.2 million to repair damage from Hurricane Earl to training academies and naval ports. The Florida Senate provided $25,740 in emergency funds to Hurricane Earl victims. By the end of the disaster declaration, the Federal Emergency Management Agency provided $1 million in public assistance and $600,000 in disaster mitigation.
