5.00 inches of rain fell in two days, the most for this week of the year since records began in 1915. The next wettest, 3.80 inches, fell in 1961.
Bruce’s center stands about 280 ft above sea level. Within three miles the land runs from 250 ft to 420 ft, a difference of 170 ft: gently rolling country. The highest named summit within 15 miles is Johnny Main Mountain, about 560 ft, 6 miles east-northeast.
Under the town center the state geologic map shows Wilcox formation (sand, clay), from the Eocene, 34 to 56 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 62×. 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: Eocene, 34 to 56 million years old. About 21 mi of the line.
Sand, clay. Age: Paleocene, 56 to 66 million years old. About 3 mi of the line.

A raindrop that lands in Bruce reaches the Gulf of America by way of the Skuna, the Yalobusha, the Yazoo and the Mississippi: about 710 river miles.
450 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bruce; river miles along the main stem, rounded.
Bruce has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 32° in January. About 58 inches of rain fall in a normal year.
On November 14 Bruce normally reaches 65° and falls to 40°. The record high is 87°, in 1955; the record low 20°, in 2019. The most rain on this date, 4.60 in, fell in 1957.
Normals 1991–2020 and records since 1915 at Calhoun City, 9 miles south-southeast. NOAA, through RCC-ACIS.
