Question: What Category 5 hurricane cause the Sqannanoa River to flood?

full_context: Document 1: Hurricane Ivan: Hurricane Ivan was a large, long-lived, Cape Verde-type hurricane that caused widespread damage in the Caribbean and United States. The cyclone was the ninth named storm, the sixth hurricane and the fourth major hurricane of the active 2004 Atlantic hurricane season. Ivan formed in early September, and reached Category 5 strength on the Saffir-Simpson Hurricane Scale. Ivan also spawned more tornadoes than any other hurricane in the Atlantic basin.
Document 2: Hurricane Hugo: Hurricane Hugo was a powerful Cape Verde–type hurricane that caused widespread damage and loss of life in the Leeward Islands, Puerto Rico, and the Southeast United States. It formed over the eastern Atlantic near the Cape Verde Islands on September 9, 1989. Hugo moved thousands of miles across the Atlantic, rapidly strengthening to briefly attain category 5 hurricane strength on its journey. It later crossed over Guadeloupe and St. Croix on September 17 and 18 as a category 4 hurricane. Weakening slightly more, it passed over Puerto Rico as a strong category 3 hurricane. Further weakening occurred several hours after re-emerging into the Atlantic, becoming downgraded to a category 2 hurricane. However, it re-strengthened into a category 4 hurricane before making landfall just slightly north of Charleston, on Isle of Palms on September 21 with 140 mph sustained winds (gusts to more than 160 mph). It had devolved to a remnant low near Lake Erie by the next day. As of 2016, Hurricane Hugo is the most intense tropical cyclone to strike the East Coast north of Florida since 1900.
Document 3: Hurricane Gilbert: Hurricane Gilbert was the costliest Atlantic hurricane on record until surpassed by Hugo of the following year as well as the most intense Atlantic hurricane until Hurricane Wilma. Gilbert was an extremely powerful tropical cyclone that formed during the 1988 Atlantic hurricane season and peaked as a Category 5 strength hurricane that brought widespread destruction to the Caribbean and the Gulf of Mexico. Gilbert was also one of the largest tropical cyclones ever observed in the Atlantic basin. At one point, its tropical storm-force winds measured 575 mi in diameter. In addition, Gilbert was the most intense tropical cyclone in recorded history to strike Mexico.
Document 4: French Broad River: The French Broad River flows 218 mi from near the town of Rosman in Transylvania County, North Carolina, into the state of Tennessee. Its confluence with the Holston River at Knoxville is the beginning of the Tennessee River. The river flows through the counties of Transylvania, Buncombe, Henderson, and Madison in North Carolina, and Cocke, Jefferson, Sevier, and Knox in Tennessee, and drains large portions of the Pisgah National Forest and the Cherokee National Forest.
Document 5: Hurricane Wilma: Hurricane Wilma was the most intense tropical cyclone ever recorded in the Atlantic basin, as well as the most intense recorded in the western hemisphere until Hurricane Patricia in 2015. Part of the record-breaking 2005 Atlantic hurricane season, which included three of the top ten most intense Atlantic hurricanes ever (along with #4 Rita and #7 Katrina), Wilma was the twenty-second storm, thirteenth hurricane, sixth major hurricane, fourth Category 5 hurricane, and second-most destructive hurricane of the 2005 season. A tropical depression formed in the Caribbean Sea near Jamaica on October 15, headed westward, and two days later intensified into a tropical storm which turned abruptly southward and was named "Wilma". Wilma continued to strengthen, and eventually became a hurricane on October 18. Shortly thereafter, explosive intensification occurred, and in only 24 hours, Wilma became a Category 5 hurricane with wind speeds of 185 mph .
Document 6: Hurricane Irene: Hurricane Irene was a large and destructive tropical cyclone, which affected much of the Caribbean and East Coast of the United States during late August 2011. Irene is ranked as the ninth-costliest hurricane in United States history. The ninth named storm, first hurricane, and first major hurricane of the 2011 Atlantic hurricane season, Irene originated from a well-defined Atlantic tropical wave that began showing signs of organization east of the Lesser Antilles. Due to development of atmospheric convection and a closed center of circulation, the system was designated as Tropical Storm Irene on August 20, 2011. After intensifying, Irene made landfall in St. Croix as a strong tropical storm later that day. Early on August 21, the storm made a second landfall in Puerto Rico. While crossing the island, Irene strengthened into a Category 1 hurricane. The storm paralleled offshore of Hispaniola, continuing to slowly intensify in the process. Shortly before making four landfalls in the Bahamas, Irene peaked as a 120 mph Category 3 hurricane.
Document 7: Swannanoa River: The Swannanoa River flows through the Swannanoa Valley of western North Carolina, and is a major tributary to the French Broad River. It begins at its headwaters in Black Mountain, NC, however, it also has a major tributary near its headwaters: Flat Creek, which begins on the slopes of Mount Mitchell. The Swannanoa River ends when it meets the French Broad at Biltmore Estate in Asheville. The river is 22 miles or 35 kilometers long, and it flows entirely within the geographical boundaries of Buncombe County. It is a valuable resource to the county, providing drinking water to the Asheville metropolitan area, and numerous recreational opportunities. In September 2004, massive rains from the remnants of Hurricane Frances and Hurricane Ivan caused the Swannanoa to flood, causing major damage to the Biltmore Village section of Asheville, and to the other communities that it flows through.
Document 8: Mills River (North Carolina): The Mills River is located in Transylvania and Henderson counties, North Carolina, United States is a tributary of the French Broad River. The river flows out of the Pisgah Ranger District of the Pisgah National Forest in two forks: the North Fork, which drains the slopes just south of the Blue Ridge Parkway between Asheville and Mount Pisgah, and the South Fork, which drains the area of the Pisgah Ranger District just east of the Cradle of Forestry in America, including the slopes of Black Mountain. The Mills River flows into the French Broad River northwest of Hendersonville between NC 191 and Interstate 26.
Document 9: List of Category 4 Atlantic hurricanes: Category 4 hurricanes are tropical cyclones that reach Category 4 intensity on the Saffir–Simpson Hurricane Scale. Category 4 hurricanes that later attained Category 5 strength are not included in this list. The Atlantic basin includes the open waters of the Atlantic Ocean, the Caribbean Sea and the Gulf of Mexico. Category 4 is the second-highest hurricane classification category on the Saffir–Simpson Hurricane Scale, and storms that are of this intensity maintain maximum sustained winds of 113–136 knots (130–156 mph, 209–251 km/h). Based on the Atlantic hurricane database, 94 hurricanes have attained Category 4 hurricane status since 1851, the start of modern meteorological record keeping. Category 4 storms are considered extreme hurricanes. Hurricane Ike, which was a Category 4 storm, brought on a 24 ft storm surge, the third greatest storm surge ever recorded (after Hurricane Katrina and Hurricane Camille, respectively).
Document 10: Cape Verde hurricane: A Cape Verde hurricane, or Cabo Verde hurricane is an Atlantic hurricane that originates at low-latitude in the deep tropics from a tropical wave that has passed over or near the Cape Verde islands after exiting the coast of West Africa. The average hurricane season has about two Cape Verde hurricanes, which are often the largest and most intense storms of the season due to having plenty of warm open ocean over which to develop before encountering land or other factors prompting weakening. A good portion of Cape Verde storms are large, some setting records. Most of the longest-lived tropical cyclones in the Atlantic basin are Cape Verde hurricanes. While many move harmlessly out to sea, some move across the Caribbean sea and into the Gulf of Mexico, becoming damaging storms for Caribbean nations, Central America, Mexico, Bermuda, the United States, and occasionally even Canada. Research projects since the 1970s have been launched to understand the formation of these storms.
Document 11: Toccoa/Ocoee River: The Toccoa River and Ocoee River are the names in use for a single 93 mi river that flows northwestward through the southern Appalachian Mountains of the southeastern United States. It is a tributary of the Hiwassee River, which it joins in Polk County, Tennessee, near the town of Benton. Three power generating dams are operated along it.
Document 12: Cullasaja River: The Cullasaja River is a short river located entirely in Macon County, North Carolina. It is a tributary of the Little Tennessee River (and in turn the Tennessee River, Ohio River and Mississippi River), into which it flows near the county seat of Franklin. It originates to the southeast, near Highlands, the county's only other town. It flows from Lake Sequoyah, which is fed by Mirror Lake and other creeks and streams originating on the western side of the Eastern Continental Divide, which runs through the east side of Highlands.
Document 13: Hurricane Gonzalo: Hurricane Gonzalo was the second tropical cyclone, after Hurricane Fay, to directly strike the island of Bermuda in a one-week time frame in October 2014, and was the first Category 4 Atlantic hurricane since Hurricane Ophelia in 2011. At the time, it was the strongest hurricane in the Atlantic since Igor in 2010. Gonzalo struck Bermuda less than a week after the surprisingly fierce Fay; 2014 was the first season in recorded history to feature two hurricane landfalls in Bermuda. A powerful Atlantic tropical cyclone that wrought destruction in the Leeward Islands and Bermuda, Gonzalo was the seventh named storm, sixth and final hurricane and only the second major hurricane of the below-average 2014 Atlantic hurricane season. The storm formed from a tropical wave on October 12, while located east of the Lesser Antilles. It made landfall on Antigua, Saint Martin, and Anguilla as a Category 1 hurricane, causing damage on those and nearby islands. Antigua and Barbuda sustained US$40 million in losses, and boats were abundantly damaged or destroyed throughout the northern Leeward Islands. The storm killed three people on Saint Martin and Saint Barthélemy. Gonzalo tracked northwestward as it intensified into a major hurricane. Eyewall replacement cycles led to fluctuations in the hurricane's structure and intensity, but on October 16, Gonzalo peaked with maximum sustained winds of 145 mph (230 km/h).
Document 14: Watauga River: The Watauga River is a large stream of western North Carolina and East Tennessee. It is 78.5 mi long with its headwaters on the slopes of Grandfather Mountain and Peak Mountain in Watauga County, North Carolina.
Document 15: Nolichucky River: The Nolichucky River is a 115 mi river that flows through Western North Carolina and East Tennessee, in the southeastern United States. Traversing the Pisgah National Forest and the Cherokee National Forest in the Blue Ridge Mountains, the river's watershed is home to some of the highest mountains in the Appalachians, including Mount Mitchell, the highest point in the eastern United States. The river is a tributary of the French Broad River, and is impounded by Nolichucky Dam near Greeneville, Tennessee.
