A shoulder, hard shoulder or breakdown lane is an emergency stopping lane by the verge on the outer side of a road or motorway. Many wider freeways, or expressways elsewhere have shoulders on both sides of each directional carriageway—in the median, as well as at the outer edges of the road, for additional safety. Shoulders are not intended for use by through traffic, although there are exceptions.
Hurricane Elena was a strong and destructive tropical cyclone that affected eastern and central portions of the United States Gulf Coast in late August and early September 1985. Threatening popular tourist destinations during Labor Day weekend, Elena repeatedly deviated from its forecast path, triggering evacuations of unprecedented extent. The hurricane wrought havoc to property and the environment between southwestern Florida and eastern Louisiana, though lesser effects were felt well beyond those areas. Elena developed on August 28 near Cuba, and after traveling lengthwise across the island with little impact, it entered the Gulf of Mexico and continued to strengthen. Initially projected to strike the central Gulf Coast, the hurricane unexpectedly veered toward the east on August 30, then stalled just 50 mi (80 km) west of Cedar Key, Florida. Despite predictions that Elena would continue eastward across Florida, the cyclone remained nearly stationary for about 48 hours, causing damage all along the eastern gulf with high winds and waves, before slowly moving northwest and ultimately making landfall near Biloxi, Mississippi, on September 2 as a Category 3 major hurricane. The storm quickly weakened upon moving ashore and dissipated on September 4.
Emergency evacuation is an immediate egress or escape of people away from an area that contains an imminent threat, an ongoing threat or a hazard to lives or property.
Contraflow lane reversal is the altering of the normal flow of traffic, typically on a controlled-access highway, to either aid in an emergency evacuation or, as part of routine maintenance activities, to facilitate widening or reconstruction of one of the highway's carriageways.
Hurricane Katrina was a powerful and devastating tropical cyclone that caused 1,392 fatalities and damages estimated at $125 billion in late August 2005, particularly in the city of New Orleans and its surrounding area. Katrina was the twelfth tropical cyclone, the fifth hurricane, and the third major hurricane of the 2005 Atlantic hurricane season. It was also the fourth-most intense Atlantic hurricane to make landfall in the contiguous United States, gauged by barometric pressure.
Hurricane preparedness in New Orleans has been an issue since the city's early settlement because of its location.
Criticism of the government response to Hurricane Katrina was a major political dispute in the United States in 2005 that consisted primarily of condemnations of mismanagement and lack of preparation in the relief effort in response to Hurricane Katrina and its aftermath. Specifically, there was a delayed response to the flooding of New Orleans, Louisiana.
Hurricane Katrina had many social effects, due the significant loss and disruption of lives it caused. The number of fatalities, direct and indirect, related to Katrina is 1,833 and over 400,000 people were left homeless. The hurricane left hundreds of thousands of people without access to their homes or jobs, it separated people from relatives, and caused both physical and mental distress on those who suffered through the storm and its aftermath, such as Post-traumatic stress disorder (PTSD).
This article contains a historical timeline of the events of Hurricane Katrina on August 23–30, 2005 and its aftermath.
Hurricane Katrina struck the United States on August 29, 2005, causing over a thousand deaths and extreme property damage, particularly in New Orleans. The incident affected numerous areas of governance, including disaster preparedness and environmental policy.
Hurricane Rita was the most intense tropical cyclone on record in the Gulf of Mexico and the fourth-most intense Atlantic hurricane ever recorded. Part of the record-breaking 2005 Atlantic hurricane season, which included three of the top ten most intense Atlantic hurricanes in terms of barometric pressure ever recorded, Rita was the seventeenth named storm, tenth hurricane, and fifth major hurricane of the 2005 season. It was also the earliest-forming 17th named storm in the Atlantic until Tropical Storm Rene in 2020. 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 21. 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 26.
Hurricane Erin was the first hurricane to strike the contiguous United States since Hurricane Andrew in 1992. The fifth tropical cyclone, fifth named storm, and second hurricane of the unusually active 1995 Atlantic hurricane season, Erin developed from a tropical wave near the southeastern Bahamas on July 31. Moving northwestward, the cyclone intensified into a Category 1 hurricane on the Saffir–Simpson scale near Rum Cay about 24 hours later. After a brief jog to the north-northwest on August 1, Erin began moving to the west-northwest. The cyclone then moved over the northwestern Bahamas, including the Abaco Islands and Grand Bahama. Early on August 2, Erin made landfall near Vero Beach, Florida, with winds of 85 mph (137 km/h). The hurricane weakened while crossing the Florida peninsula and fell to tropical storm intensity before emerging into the Gulf of Mexico later that day.
The Louisiana Department of Transportation and Development (DOTD) is a state government organization in the United States, in charge of maintaining public transportation, roadways, bridges, canals, select levees, floodplain management, port facilities, commercial vehicles, and aviation which includes 69 airports, in the U.S. state of Louisiana. The agency has approximately five thousand personnel on staff and an operating budget of $2.3 billion. DOTD operations are run through nine district offices across the state.
Hurricane Gustav was the second most destructive hurricane of the 2008 Atlantic hurricane season. The seventh tropical cyclone, third hurricane, and second major hurricane of the season, Gustav caused serious damage and casualties in Haiti, the Dominican Republic, Jamaica, the Cayman Islands, Cuba and the United States. Gustav caused at least $8.31 billion (2008 USD) in damages.
The effects of Hurricane Georges in Louisiana included $30.1 million in damage and three deaths. Forming from a tropical wave over the Atlantic Ocean, Georges attained a peak intensity of 155 mph (249 km/h) on September 20, 1998. Over the following several days, the storm tracked through the Greater Antilles and later entered the Gulf of Mexico on September 28, the Category 2 storm made landfall in Mississippi before dissipating on October 1. Before landfall, about 500,000 residents in Louisiana evacuated from low-lying areas. The mayor of New Orleans declared a state of emergency to allow federal assistance into the state. After nearly 1.5 million people were urged to evacuate coastal areas, officials described the evacuation as "probably the largest [...] we have ever achieved".
Hurricane Floyd threatened Florida as a major hurricane roughly three times as large as Hurricane Andrew. Floyd originated from a tropical wave well east of the Lesser Antilles on September 7. While approaching the Bahamas, the storm strengthened significantly between September 12 and September 13. On the latter day, Floyd peaked as a strong Category 4 hurricane on the Saffir–Simpson scale. However, upon moving closer to the Bahamas, the storm fluctuated in intensity between a Category 3 and a Category 4 hurricane. A subtropical ridge eroded by a mid- to upper-tropospheric trough over the eastern United States caused Floyd to curve northwestward over the Abaco Islands and later to northeast, avoiding a potentially catastrophic landfall in Florida. The storm made its closest approach to Florida early on September 15, passing about 110 mi (180 km) east of Cape Canaveral.
Hurricane Florence was a powerful and long-lived Cape Verde hurricane that caused catastrophic damage in the Carolinas in September 2018, primarily as a result of freshwater flooding due to torrential rain. The sixth named storm, third hurricane, and the first major hurricane of the 2018 Atlantic hurricane season, Florence originated from a strong tropical wave that emerged off the west coast of Africa on August 30, 2018. The wave steadily organized, and strengthened into a tropical depression on the next day near Cape Verde. Progressing along a steady west-northwest trajectory, the system gradually strengthened, acquiring tropical storm strength on September 1. An unexpected bout of rapid intensification ensued on September 4–5, culminating with Florence becoming a Category 4 major hurricane on the Saffir–Simpson scale (SSHWS), with estimated maximum sustained winds of 130 mph (215 km/h). Strong wind shear then led to rapid weakening, and Florence weakened to tropical storm strength on September 7. Shifting steering currents led to a westward turn into a more suitable environment; as a result, Florence reintensified to hurricane strength on September 9 and major hurricane status by the following day. Florence reached peak intensity on September 11, with 1-minute winds of 150 mph (240 km/h) and a minimum central pressure of 937 mbar (27.7 inHg). An unexpected eyewall replacement cycle and decreasing oceanic heat content caused a steady weakening trend; however, the storm grew in size at the same time. Early on September 14, Florence made landfall in the United States just south of Wrightsville Beach, North Carolina as a Category 1 hurricane, and weakened further as it slowly moved inland under the influence of weak steering currents. Florence degenerated into a post-tropical cyclone over West Virginia on September 17 and was absorbed by another frontal storm two days later.
The COVID-19 pandemic coincided with record-breaking wildfires in the western United States and a record number of hurricane landfalls in the southeastern United States. Emergency evacuation may be required for people living in areas threatened by natural disasters. Historic procedures maximizing capacity of public transport and emergency shelters may be inconsistent with quarantine and physical distancing measures related to the COVID-19 pandemic. It is not advisable to set up congregate shelters in an environment heavily impacted by a pandemic. Non-congregate shelters typically provide more effective physical distancing. Examples include buildings with single room occupancy, hotels or dormitories with private sleeping spaces but possibly shared bathroom or cooking facilities. Thousands of evacuees from Hurricane Laura were still in emergency lodgings as Hurricane Delta approached the Louisiana coast. Six-thousand from southwest Louisiana were in twelve New Orleans area hotels. Three-thousand-five-hundred remained in shelters as Hurricane Zeta approached Louisiana. A volcanic eruption on the island of Saint Vincent in April 2021 caused evacuation of sixteen-thousand people. Four-thousand evacuees were placed in eighty-nine government shelters after being tested for COVID-19, with those testing positive taken to isolation centers. Six-thousand evacuees found shelter in private homes.
The approach of Hurricane Rita towards the United States Gulf Coast in September 2005 triggered one of the largest mass evacuations in U.S. history. Between 2.5 and 3.7 million people evacuated from the Gulf coast, mostly from the Greater Houston area of Texas, with forecasts from the National Hurricane Center projecting Rita to strike the Texas Gulf Coast. Seeking to avoid a repeat of the devastation caused by Hurricane Katrina in parts of Louisiana and Mississippi less than a month prior, local officials began issuing evacuation orders on September 21 before the issuance of hurricane watches and warnings. Although evacuation orders anticipated smaller numbers of evacuees, uncertainties in projections of Rita's path and the fresh memory of Katrina's aftermath led many to evacuate, including from otherwise safe areas outside the scope of evacuation orders; approximately two-thirds of evacuees were not required to evacuate. The unexpectedly large scale of the evacuation overwhelmed Texas highways, producing widespread gridlock that was exacerbated by the implementation of previously unplanned contraflow on Interstates 10 and 45 while the evacuation was ongoing. Most traffic associated with the evacuation was clear of the threatened coastal areas by the early morning of September 23.
The Southeastern United States, extending from South Florida to Louisiana and areas inland, was severely affected by Hurricane Katrina, causing many deaths and billions in damages. After developing on August 23, Katrina made landfall near the border of Broward and Miami-Dade counties with 80 mph (130 km/h) winds on August 25. After emerging from the state, Katrina intensified into one of the strongest Atlantic hurricanes, becoming a Category 5 on the Saffir–Simpson scale. It moved ashore near the border of Louisiana and Mississippi and weakened as it moved inland, dissipating on August 31.
