Nor'easters typically impact the eastern United States and are similar to <br /> hurricanes in respect to their effects. Unlike hurricanes,however, nor'easters aze extra- <br /> tropical storms, deriving their strength from horizontal gradients in temperature-they form <br /> as a result of a drop in temperature. <br /> Nor'easters affect the state in a similar fashion as hurricanes in that they produce heavy surf <br /> and high winds. A nor'easter occurring during winter months may also produce ice hazards <br /> and effects similar to those of a severe winter storm. <br /> Orange County, including the Town of Carrboro and Town of Hillsborough, would <br /> typically suffer the same effects from a nor'easter as from a hurricane. Because of Orange <br /> County's inla�nd location,the impact of a nor'easter would not be expected to be <br /> exceptionally severe.The occurrence of a nor'easter often produces substantial amounts of <br /> precipitation and strong winds.Nor'easters occurring in the winter may result in <br /> accumulation of snow and/or ice. <br /> According to an analysis of nor'easter frequency, fewer nor'easters occurred during the <br /> 1980's. However,the frequency of major nor'easters (Class 4 or 5)has increased in recent <br /> years. From 1987 to 1993 at least one class 4 or 5 storm occurred each year along the <br /> 15 <br />
