4.37 inches of rain fell in two days, the most for this week of the year since records began in 1912. The next wettest, 4.32 inches, fell in 2020.
Fincastle’s center stands about 1,210 ft above sea level. Within three miles the land runs from 1,020 ft to 1,480 ft, a difference of 460 ft: hilly country. The highest named summit within 15 miles is Rich Patch Mountains, about 3,700 ft, 14 miles north-northwest.
Under the town center the state geologic map shows Elbrook Formation (dolostone, limestone), from the Cambrian, 487 to 542 million years old.
The section below crosses 15 rock units mapped at the surface.

Dolostone, limestone. Age: Cambrian, 487 to 542 million years old. About 5 mi of the line.
Shale. Age: Cambrian, 487 to 542 million years old. About 4 mi of the line.
Sandstone, conglomerate, siltstone. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Quartzite, conglomerate, sandstone. Age: Cambrian, 487 to 542 million years old. About 3 mi of the line.
Shale, sandstone. Age: Devonian, 359 to 422 million years old. About 2 mi of the line.

From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 9 smaller units along the line are not listed.

A raindrop that lands in Fincastle reaches Chesapeake Bay and the Atlantic Ocean by way of Town Branch, Catawba Creek and the James: about 330 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Fincastle; river miles along the main stem, rounded.
Fincastle has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 29° in January. A normal year brings about 15 inches of snow; with the rain, that comes to about 43 inches of water.
On November 14 Fincastle normally reaches 60° and falls to 38°. The record high is 82°, in 1993; the record low 13°, in 1986. The most rain on this date, 1.68 in, fell in 1972.
Normals 1991–2020 and records since 1912 from the Roanoke Area threaded record (Roanoke-Blacksburg Regional Airport, 14 miles south-southwest). NOAA, through RCC-ACIS.
