North Carolina <=SEP=> North Carolina ( -LSB- nɔrθ_kærəˈlaɪnə -RSB- ) is a state in the southeastern region of the United States . The state borders South Carolina and Georgia to the south , Tennessee to the west , Virginia to the north , and the Atlantic Ocean to the east . North Carolina is the 28th most extensive and the 9th most populous of the U.S. states . The state is divided into 100 counties . The capital is Raleigh . The most populous municipality is Charlotte , which is the second largest banking center in the United States after New York City .   The state has a wide range of elevations , from sea level on the coast to 6684 ft at Mount Mitchell , the highest point in North America east of the Mississippi River . The climate of the coastal plains is strongly influenced by the Atlantic Ocean . Most of the state falls in the humid subtropical climate zone . More than 300 mi from the coast , the western , mountainous part of the state has a subtropical highland climate .

Hurricane Agnes <=SEP=> Hurricane Agnes was , at the time , the costliest hurricane to hit the United States in recorded history . The second tropical cyclone and first named storm of the 1972 Atlantic hurricane season , Agnes developed on June 14 from the interaction of a polar front and an upper trough over the Yucatán Peninsula . Initially forming as a tropical depression , the storm headed slowly eastward and emerged into the western Caribbean Sea on June 15 . Once in the Caribbean , the depression began to strengthen , and by the following day , it became Tropical Storm Agnes . Thereafter , Agnes slowly curved northward and passed just west of Cuba on June 17 . Early on June 18 , the storm intensified enough to be upgraded to Hurricane Agnes . Heading northward , the hurricane eventually made landfall near Panama City , Florida late on June 19 . After moving inland , Agnes rapidly weakened and was only a tropical depression when it entered Georgia . The weakening trend halted as the storm crossed over Georgia and into South Carolina . While over eastern North Carolina , Agnes re-strengthened into a tropical storm on June 21 , as a result of baroclinic activity . Early the following day , the storm emerged into the Atlantic Ocean before re-curving northwestward and making landfall near New York City as a strong tropical storm . Agnes quickly became an extratropical cyclone on June 23 , and tracked to the northwest of Great Britain before becoming absorbed by another cyclone on July 6 .   Though it moved slowly across the Yucatán Peninsula , damage in Mexico is unknown . Although the storm bypassed the tip of Cuba , heavy rainfall occurred , killing seven people . In Florida , Agnes caused a significant tornado outbreak , with at least 26 confirmed twisters , two of which were spawned in Georgia . The tornadoes and two initially unconfirmed tornadoes in Florida alone resulted in over $ 4.5 million ( 1972 USD ) in damage and six fatalities . At least 2,082 structures in Florida suffered either major damage or were destroyed . About 1,355 other dwellings experienced minor losses . Though Agnes made landfall as a hurricane , no hurricane-force winds were reported . Along the coast abnormally high tides resulted in extensive damage , especially between Apalachicola and Cedar Key . Light to moderate rainfall was reported in Florida , though no significant flooding occurred . In Georgia , damage was limited to two tornadoes , which caused approximately $ 275,000 in losses . Minimal effects were also recorded in Alabama , Connecticut , Delaware , Rhode Island , South Carolina , and Tennessee ; though one fatality was reported in Delaware . The most significant effects , by far , occurred in Pennsylvania , mostly due to intense flooding . The hurricane severely flooded the Susquehanna River and the Lackawanna River causing major damage to the Scranton/Wilkes-Barre metropolitan area . In both Pennsylvania and New Jersey combined , about 43,594 structures were either destroyed or significantly damaged . In Canada , a mobile home was toppled , killing two people . Overall , Agnes caused 128 fatalities and nearly $ 3 billion in damage , though more recently , it is estimated that there were $ 2.1 billion in losses associated with the storm . Due to the significant effects , the name Agnes was retired in the spring of 1973 .

2008 Atlantic hurricane season <=SEP=> The 2008 Atlantic hurricane season was a very active hurricane season with sixteen named storms formed , including eight that became hurricanes and five that became major hurricanes . The season officially started on June 1 and ended on November 30 . These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin . However , the formation of Tropical Storm Arthur caused the season to start two days early . This season is the fourth most costly on record , behind only the 2004 , 2005 and 2012 seasons , with over $ 47.5 billion in damage ( 2008 USD ) . It was the fourth busiest year since 1944 and the only year on record in which a major hurricane existed in every month from July through November in the North Atlantic . Bertha became the longest lived July tropical cyclone on record for the basin , the first of several long-lived systems during 2008 . The season was devastating for Haiti , where over 800 people were killed by four consecutive tropical cyclones ( Fay , Gustav , Hanna , and Ike ) , especially Hanna , in August and September . Hurricane Paloma 's outer rain bands also made landfall over Haiti . Ike was also the most destructive storm of the season , as well as the strongest , devastating Cuba as a major hurricane and later making landfall near Galveston , Texas at Category 2 ( nearly Category 3 ) intensity .   One very unusual feat was a streak of tropical cyclones affecting land . All but one system impacted land in 2008 . The unprecedented number of storms with impact led to one of the deadliest and destructive seasons in the history of the Atlantic basin , especially with Hurricane Ike , as its overall damages made it the third costliest hurricane in the Atlantic .

Atlantic hurricane <=SEP=> An Atlantic hurricane or tropical storm is a tropical cyclone that forms in the Atlantic Ocean , usually in the summer or fall . A hurricane differs from a cyclone or typhoon only on the basis of location . A hurricane is a storm that occurs in the Atlantic Ocean and northeastern Pacific Ocean , a typhoon occurs in the northwestern Pacific Ocean , and a cyclone occurs in the south Pacific or Indian Ocean .   Tropical cyclones can be categorized by intensity . Tropical storms have one-minute maximum sustained winds of at least 39 mph ( 34 knots , 17 m/s , 63 km/h ) , while hurricanes have one-minute maximum sustained winds exceeding 74 mph ( 64 knots , 33 m/s , 119 km/h ) . Most North Atlantic tropical storms and hurricanes form between June 1 and November 30 . The United States National Hurricane Center monitors the basin and issues reports , watches , and warnings about tropical weather systems for the North Atlantic Basin as one of the Regional Specialized Meteorological Centers for tropical cyclones , as defined by the World Meteorological Organization .   In recent times , tropical disturbances that reach tropical storm intensity are named from a predetermined list . Hurricanes that result in significant damage or casualties may have their names retired from the list at the request of the affected nations in order to prevent confusion should a subsequent storm be given the same name . On average , in the North Atlantic basin ( from 1966 to 2009 ) 11.3 named storms occur each season , with an average of 6.2 becoming hurricanes and 2.3 becoming major hurricanes ( Category 3 or greater ) . The climatological peak of activity is around September 11 each season .   In March 2004 , Catarina was the first hurricane-intensity tropical cyclone ever recorded in the Southern Atlantic Ocean . Since 2011 , the Brazilian Navy Hydrographic Center has started to use the same scale of the North Atlantic Ocean for tropical cyclones in the South Atlantic Ocean and assign names to those which reach 35 kn .
