With this reduction, Onslow County has assigned zoning districts to the affected properties. Snow in North Carolina is seen on a regular basis in the mountains. What a Planting Zone is NOT. However, this also varies greatly across the state. It’s common for people to look at the USDA Plant Hardiness Zone Map and assume it would be divided out by region. [16], In most years, the greatest weather-related economic loss incurred in North Carolina is due to severe weather spawned by summer thunderstorms. Cold fronts from Canada are typically reduced in intensity by the mountains. However, several storms have dropped 18 inches (460 mm) or more of snow within normally warm areas. "Winter Weather Forecasting throughout the Eastern United States. For the purposes of this set of maps, the three North Carolina regions — the Mountains, Piedmont, and Coastal Plain — are defined by the The mountains often act as a "shield", blocking low temperatures and storms from the Midwest from entering the Piedmont of North Carolina.[1]. For more information about observing sites in the area, regardless of if their data was used in this study, please visit NCEI's Climate Data Online.

These eight climate zones are illustrated in the form of a climate zone map which was created using Bureau of Meteorology climatic data with two supplementary zones added to accommodate an additional temperate zone and alpine area. The Appalachian Mountains are frequently visited at this time of year, due to the leaves changing color in the trees.[23]. These maps reflect those changes. This page offers some general guidelines on the definitions of the various climate regions based on heating degree-days, average temperatures, and precipitation. climate and weather data, such as mean temperature, precipitation, and drought indices. The 2012 North Carolina USDA planting map, as seen above, indicates which growing zones cover certain areas of the state.

[23] Snow is common in the mountains, although many ski resorts use snowmaking equipment to make sure there is always snow on their land. A more sophisticated approach has been followed by Sunset which defines Climate Zone Maps based not only on hardiness or heat tolerance, but also on precipitations, wind, humidity and various other climate related factors. A weather station at Oak Island reported maximum sustained winds of 140 miles per hour (230 km/h), while in Raleigh winds of 90 miles per hour (140 km/h) were measured.

[23] The average ocean temperature in Southport in January is still higher than the average ocean temperature in Maine during July. Based on the 1990 USDA Hardiness Zone Map, this interactive version covers the state of … The hurricane caused 19 deaths and significant destruction. These storms affect limited areas, with their hail and wind accounting for an average annual loss of over US$5 million. If the storms track sufficiently far to the east, snow will be limited to the eastern part of the state (as with the December 22–23, 1989 storm).
