4.37 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 4.02 inches, fell in 2018.
Warrenton’s center stands about 390 ft above sea level. Within three miles the land runs from 270 ft to 480 ft, a difference of 210 ft: rolling country.
Under the town center the state geologic map shows Granitic Rock, from the Late Mississippian to Permian, 265 to 325 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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: Late Mississippian to Permian, 265 to 325 million years old. About 11 mi of the line.
Mica-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 10 mi of the line.
Biotite-gneiss. Age: Proterozoic, 542 to 2,500 million years old. About 2 mi of the line.
Biotite-gneiss, mica-schist, amphibolite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 1 mi of the line.

A raindrop that lands in Warrenton reaches Pamlico Sound and the Atlantic Ocean by way of Horse Creek, Fishing Creek, the Tar and the Pamlico: about 190 river miles.
95 miles of the trip are on Fishing Creek.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Warrenton; river miles along the main stem, rounded.
Warrenton has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 26° in January. About 49 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Warrenton normally reaches 63° and falls to 35°. The record high is 81°, in 1951; the record low 18°, in 1976. The most rain on this date, 1.50 in, fell in 1940.
Normals 1991–2020 and records since 1893 at Henderson 2 NNW, 15 miles west-southwest. NOAA, through RCC-ACIS.
