4.29 inches of rain fell in two days, the most for this week of the year since records began in 1946. The next wettest, 4.20 inches, fell in 2009.
Danbury’s center stands about 840 ft above sea level. Within three miles the land runs from 720 ft to 1,890 ft, a difference of 1,170 ft: steep hill country. The highest named summit within 15 miles is Moores Knob, about 2,540 ft, 4 miles west-southwest.
Under the town center the state geologic map shows Metagraywacke and Muscovite-Biotite Schist (metagraywacke, muscovite-schist), from the Neoproterozoic to Cambrian, 487 to 1,000 million years old.
The section below crosses 2 rock units mapped at the surface.

Metagraywacke, muscovite-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 19 mi of the line.
Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 5 mi of the line.

A raindrop that lands in Danbury reaches Albemarle Sound and the Atlantic Ocean by way of Scott Branch, the Dan and the Roanoke: about 340 river miles.
Lake on the way: Roanoke Rapids Lake.
130 miles of the trip are on the Dan.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Danbury; river miles along the main stem, rounded.
Danbury has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 28° in January. A normal year brings about 9 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Danbury normally reaches 60° and falls to 36°. The record high is 78°, in 1964; the record low 16°, in 1986. The most rain on this date, 2.15 in, fell in 1972.
Normals 1991–2020 and records since 1946 at Danbury, 2 miles northeast, 180 ft higher. NOAA, through RCC-ACIS.
