5.36 inches of rain fell in two days, the most for this week of the year since records began in 1966. The next wettest, 5.18 inches, fell in 2009.
Grifton’s center stands about 30 ft above sea level. Within three miles the land runs from 10 ft to 110 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Peedee Formation (sand, clay), from the Cretaceous, 66 to 145 million years old.
The section below crosses 5 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.
Sand, clay. Age: Cretaceous, 66 to 145 million years old. About 15 mi of the line.
Limestone. Age: Tertiary, 2.6 to 66 million years old. About 4 mi of the line.
Clay. Age: Tertiary, 2.6 to 66 million years old. About 3 mi of the line.
Clay, sand. Age: Cretaceous, 66 to 145 million years old. About 1 mi of the line.
Sand. Age: Tertiary, 2.6 to 66 million years old. About 1 mi of the line.

A raindrop that lands in Grifton reaches Pamlico Sound and the Atlantic Ocean by way of Contentnea Creek and the Neuse: about 75 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Grifton; river miles along the main stem, rounded.
Grifton has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 35° in January. About 53 inches of rain fall in a normal year.
On November 14 Grifton normally reaches 67° and falls to 44°. The record high is 82°, in 1993; the record low 23°, in 1976. The most rain on this date, 0.90 in, fell in 1997.
Normals 1991–2020 and records since 1966 at Kinston Ag Research, 9 miles southwest. NOAA, through RCC-ACIS.
