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.
Montvale’s center stands about 990 ft above sea level. Within three miles the land runs from 920 ft to 2,360 ft, a difference of 1,440 ft: steep hill country. The highest named summit within 15 miles is Apple Orchard Mountain, about 4,220 ft, 15 miles northeast.
Under the town center the state geologic map shows Rome Formation (shale), from the Cambrian, 487 to 542 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 10×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granulite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 11 mi of the line.
Shale. Age: Cambrian, 487 to 542 million years old. About 7 mi of the line.
Granulite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.
Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Mylonite, gneiss, cataclasite. Age: Proterozoic to Phanerozoic, less than 2,500 million years old. About 0.3 mi of the line.

A raindrop that lands in Montvale reaches Albemarle Sound and the Atlantic Ocean by way of South Fork Goose Creek, Goose Creek and the Roanoke: about 330 river miles.
Lake on the way: Roanoke Rapids Lake.
130 miles of the trip are on the Roanoke.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Montvale; river miles along the main stem, rounded.
Montvale 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 Montvale 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 west-southwest, 150 ft higher). NOAA, through RCC-ACIS.
