Question: How many tornadoes are there per year in the state that borders the east of the state where Hello Love's performer lived in when he died?

full_context: Document 1: North Carolina: North Carolina averages fewer than 20 tornadoes per year, many of them produced by hurricanes or tropical storms along the coastal plain. Tornadoes from thunderstorms are a risk, especially in the eastern part of the state. The western Piedmont is often protected by the mountains, which tend to break up storms as they try to cross over; the storms will often re-form farther east. Also a weather phenomenon known as "cold air damming" often occurs in the northwestern part of the state, which can also weaken storms but can also lead to major ice events in winter.
Document 2: North Carolina: Severe weather occurs regularly in North Carolina. On the average, a hurricane hits the state once a decade. Destructive hurricanes that have struck the state include Hurricane Fran, Hurricane Floyd, and Hurricane Hazel, the strongest storm to make landfall in the state, as a Category 4 in 1954. Hurricane Isabel stands out as the most damaging of the 21st century. Tropical storms arrive every 3 or 4 years. In addition, many hurricanes and tropical storms graze the state. In some years, several hurricanes or tropical storms can directly strike the state or brush across the coastal areas. Only Florida and Louisiana are hit by hurricanes more often. Although many people believe that hurricanes menace only coastal areas, the rare hurricane which moves inland quickly enough can cause severe damage; for example, in 1989, Hurricane Hugo caused heavy damage in Charlotte and even as far inland as the Blue Ridge Mountains in the northwestern part of the state. On the average, North Carolina has 50 days of thunderstorm activity per year, with some storms becoming severe enough to produce hail, flash floods, and damaging winds.

The state line between Tennessee and North Carolina crosses the summit. The state's lowest point is the Mississippi River at the Mississippi state line (the lowest point in Memphis, nearby, is at 195 ft (59 m)). The geographical center of the state is located in Murfreesboro.

Document 7: Tennessee: Tennessee was admitted to the Union on June 1, 1796 as the 16th state. It was the first state created from territory under the jurisdiction of the United States federal government. Apart from the former Thirteen Colonies only Vermont and Kentucky predate Tennessee's statehood, and neither was ever a federal territory. The state boundaries, according to the Constitution of the State of Tennessee, Article I, Section 31, stated that the beginning point for identifying the boundary was the extreme height of the Stone Mountain, at the place where the line of Virginia intersects it, and basically ran the extreme heights of mountain chains through the Appalachian Mountains separating North Carolina from Tennessee past the Indian towns of Cowee and Old Chota, thence along the main ridge of the said mountain (Unicoi Mountain) to the southern boundary of the state; all the territory, lands and waters lying west of said line are included in the boundaries and limits of the newly formed state of Tennessee. Part of the provision also stated that the limits and jurisdiction of the state would include future land acquisition, referencing possible land trade with other states, or the acquisition of territory from west of the Mississippi River.
Document 8: Climate of North Carolina: There is an average of forty - five inches of rain a year (fifty in the mountains). July storms account for much of this precipitation. As much as 15% of the rainfall during the warm season in the Carolinas can be attributed to tropical cyclones. Mountains usually see some snow in the fall and winter. Moist winds from the southwest drop an average of 80 inches (2,000 mm) of precipitation on the western side of the mountains, while the northeast - facing slopes average less than half that amount.
Document 9: Loretta Lynn: Lynn's relationship with the Wilburn Brothers and her appearances on the Grand Ole Opry, beginning in 1960, helped Lynn become the number one female recording artist in country music. Her contract with the Wilburn Brothers gave them the publishing rights to her material. She was still fighting to regain these rights 30 years after ending her business relationship with them but was ultimately denied the publishing rights. Lynn stopped writing music in the 1970s because of these contracts. Although Kitty Wells had become the first major female country vocalist during the 1950s, by the time Lynn recorded her first record, only three other women -- Patsy Cline, Skeeter Davis, and Jean Shepard -- had become top stars. Lynn joined The Grand Ole Opry on September 25, 1962.
Document 10: Climate of North Carolina: Snow in North Carolina is seen on a regular basis in the mountains. North Carolina averages 5 inches (130 mm) of snow a year. However, this also varies greatly across the state. Along the coast, most areas register less than 2 inches (51 mm) per year while the state capital, Raleigh averages 7.5 inches (190 mm). Farther west in the Piedmont - Triad, the average grows to approximately 9 inches (230 mm). The Charlotte area averages approximately 6.5 inches (170 mm). The mountains in the west act as a barrier, preventing most snowstorms from entering the Piedmont. When snow does make it past the mountains, it is usually light and is seldom on the ground for more than two or three days. However, several storms have dropped 18 inches (460 mm) or more of snow within normally warm areas. The 1993 Storm of the Century that lasted from March 11 to March 15 affected locales from Canada to Central America, and brought a significant amount of snow to North Carolina. Newfound Gap received more than 36 inches (0.91 m) of snow with drifts more than 5 feet (1.5 m), while Mount Mitchell measured over 4 feet (1.2 m) of snow with drifts to 14 feet (4.3 m). Most of the northwestern part of the state received somewhere between 2 feet (0.61 m) an 3 feet (0.91 m) of snow.
