4.36 inches of rain fell in two days, the most for this week of the year since records began in 1887. The next wettest, 3.93 inches, fell in 1920.
Rolesville’s center stands about 440 ft above sea level. Within three miles the land runs from 260 ft to 440 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Foliated to Massive Granitic Rock, from the Early Pennsylvanian to Permian, 270 to 320 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 61×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granitic. Age: Early Pennsylvanian to Permian, 270 to 320 million years old. About 24 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Rolesville reaches Pamlico Sound and the Atlantic Ocean by way of Harris Creek and the Neuse: about 220 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Rolesville; river miles along the main stem, rounded.
Rolesville has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 32° in January. A normal year brings about 5 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Rolesville normally reaches 63° and falls to 40°. The record high is 81°, in 1999; the record low 20°, in 1977. The most rain on this date, 1.57 in, fell in 1940.
