Louisiana
The State of Louisiana (pronounced /luːˌiːziˈænə/ or /ˌluːziˈænə/ ; French: État de Louisiane , ; Louisiana Creole: Léta de la Lwizyàn ) is a state located in the southern region of the United States of America. Its capital is Baton Rouge and largest city is New Orleans. Louisiana is the only state in the U.S. with political subdivisions termed parishes, which are local governments equivalent to counties. The largest parish by population is Jefferson Parish, and the largest by land area is Cameron Parish.
Some Louisiana urban environments have a multicultural, multilingual heritage, being so strongly influenced by an admixture of 18th century French, Spanish and African cultures that they have been considered somewhat exceptional in the U.S. Before the American influx and statehood at the beginning of the 19th century, the territory of current Louisiana State had been a Spanish and French colony. In addition, the pattern of development included importing numerous Africans in the 18th century, with many from the same region of West Africa, thus concentrating their culture.
Louisiana has a humid subtropical climate (Koppen climate classification Cfa ), perhaps the most "classic" example of a humid subtropical climate of all the Southcentral states, with long, hot, humid summers and short, mild winters. The subtropical characteristics of the state are due in large part to the influence of the Gulf of Mexico, which even at its farthest point is no more than 200 miles (320 km) away. Precipitation is frequent throughout the year, although the summer is slightly wetter than the rest of the year. There is a dip in precipitation in October. Southern Louisiana receives far more copious rainfall, especially during the winter months. Summers in Louisiana are hot and humid, with high temperatures from mid-June to mid-September averaging 90 °F (32 °C) or more and overnight lows averaging above 70 °F (22 °C). In the summer, the extreme maximum temperature is much warmer in the north than in the south, with temperatures near the Gulf of Mexico occasionally reaching 100 °F (38 °C), although temperatures above 95 °F (35 °C) are commonplace. In northern Louisiana, the temperatures reach above 105 °F (41 °C) in the summer.
Temperatures are generally mildly warm in the winter in the southern part of the state, with highs around New Orleans, Baton Rouge, the rest of south Louisiana, and the Gulf of Mexico averaging 66 °F (19 °C), while the northern part of the state is mildly cool in the winter with highs averaging 59 °F (15 °C). The overnight lows in the winter average well above freezing throughout the state, with 46 °F (8 °C) the average near the Gulf and an average low of 37 °F (3 °C) in the winter in the northern part of the state. Louisiana does have its share of cold fronts, which frequently drop the temperatures below 20 °F (-8 °C) in the northern part of the state, but almost never do so in the southern part of the state. Snow is not very common near the Gulf of Mexico, although those in the northern parts of the state can expect one to three snowfalls per year, with the frequency increasing northwards.
Louisiana is often affected by tropical cyclones and is very vulnerable to strikes by major hurricanes, particularly the lowlands around and in the New Orleans area. The unique geography of the region with the many bayous, marshes and inlets can make major hurricanes especially destructive. The area is also prone to frequent thunderstorms, especially in the summer. The entire state averages over 60 days of thunderstorms a year, more than any other state except Florida. Louisiana averages 27 tornadoes annually. The entire state is vulnerable to a tornado strike, with the extreme southern portion of the state slightly less so than the rest of the state. Tornadoes are much more common from January to March in the southern part of the state, and from February through March in the northern part of the state.
The southern coast of Louisiana in the United States is among the fastest disappearing areas in the world. Rising waters have led to the state losing a land mass equivalent to 30 football fields every day. And as the communities disappear, more and more people are leaving the region.
Hurricanes
- September 1, 2008, Gustav made landfall along the Louisiana coast near Cocodrie in southeastern Louisiana. As late as August 31 it had been projected by the National Hurricane Center that the hurricane would remain at Category 3 or above on September 1, but in the event the center of Gustav made landfall as a strong Category 2 hurricane (1 mph below Category 3), and dropped to Category 1 soon after. As a result of NHC's forecasts there had been a massive evacuation of New Orleans amid warnings (for example from the city's mayor, Ray Nagin) that this would be the “storm of the century”, potentially more devastating than Katrina almost exactly three years earlier, but these fears were not realised. Nevertheless, a significant number of deaths were caused by or attributed to Gustav, and around 1.5 million people were without power in Louisiana on September 1.
- September 24, 2005, Rita (Category 3 at landfall) struck southwestern Louisiana, flooding many parishes and cities along the coast, including Cameron Parish, Lake Charles, and other towns. The storm's winds further weakened the damaged levees in New Orleans and caused renewed flooding in parts of the city.
- August 29, 2005, Katrina (Category 3 at landfall) struck and devastated southeastern Louisiana, while breached and undermined levees in New Orleans allowed 80% of the city to flood. Most people had been evacuated but the majority of the population became homeless. The city was virtually closed until October. It is estimated that more than two million people in the Gulf region were displaced by the hurricane, and more than 1,500 fatalities resulted in Louisiana alone. A public outcry criticized governments at the local, state, and federal levels, citing that preparation and response was neither fast nor adequate.
- Oct. 3, 2002, Lili (Category 1 at landfall)
- August 1992, Andrew (Category 3 at landfall) struck south-central Louisiana. It killed four people; knocked out power to nearly 150,000 citizens; and destroyed hundreds of millions of dollars of crops in the state.
- August 1969, Camille (Category 5) caused a 23.4 ft (7.1 m). storm surge and killed 250 people. Although Camille officially made landfall in Mississippi and the worst impacts were felt there, it also had effects in Louisiana. New Orleans was spared the brunt of the storm and remained dry, with the exception of mild rain-generated flooding in the most low-lying areas.
- September 9, 1965, Betsy (Category 3 at landfall) came ashore in Louisiana, causing massive destruction as the first hurricane in history to cause one billion dollars in damage (over ten billion in inflation-adjusted USD). The storm hit New Orleans particularly hard by flooding approximately 35% of the city (including the Lower 9th Ward, Gentilly, and parts of Mid-City), and pushing the death toll in the state to 76.
- June 1957, Audrey (Category 4) devastated southwest Louisiana, destroying or severely damaging 60–80 percent of the homes and businesses from Cameron to Grand Chenier. 40,000 people were left homeless and more than 300 people were killed in the state.
- August 10, 1856, Hurricane One (Category 4) made landfall at Last Island, Louisiana. The 25 mile long barrier island resort community was devastated by being split into 5 separate islands, and over 200 people were killed.
Geology
The underlying strata of the state are of Cretaceous age and are covered by alluvial deposits of Tertiary and post-Tertiary origin. A large part of Louisiana is the creation and product of the Mississippi River. It was originally covered by an arm of the sea, and has been built up by the silt carried down the valley by the great river.
Near the coast, there are many salt domes, where salt is mined and oil is often found. Salt domes also exist in North Louisiana.
Due both to extensive flood control measures along the Mississippi River and natural subsidence, Louisiana is now suffering the loss of coastal land area. State and federal government efforts to halt or reverse this phenomenon are underway; others are being sought. There is one bright spot, however; the Atchafalaya River is creating new delta land in the South-Central portion of the state. This active delta lobe also indicates that the Mississippi is seeking a new path to the Gulf. Much engineering effort is devoted to keeping the river near its traditional route, as the state's economy and shipping depends on it.
Geographic and statistical areas
Louisiana is divided into 64 parishes (the equivalent of counties in most other states). The term "parish" is unique to Louisiana and is due to its French / Spanish heritage; the original boundaries of the civilian county governments were coterminous with the local Roman Catholic parishes.
The Intracoastal Waterway is an important means of transporting commercial goods such as petroleum and petroleum products, agricultural produce, building materials and manufactured goods.
