The Poplarville plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
6.76 inches of rain fell in two days, the most for this week of the year since records began in 1896. The next wettest, 3.95 inches, fell in 1947.
Poplarville’s center stands about 320 ft above sea level. Within three miles the land runs from 210 ft to 350 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Citronelle formation (sand, gravel), from the Pliocene to Pleistocene, less than 5.3 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 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.
Clay, sand. Age: Miocene, 5.3 to 23 million years old. About 17 mi of the line.
Sand, gravel. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 7 mi of the line.

A raindrop that lands in Poplarville reaches the Gulf of America by way of Poplar Springs Branch and the Wolf River: about 65 river miles.

Poplarville has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 38° in January. About 65 inches of rain fall in a normal year.
On November 14 Poplarville normally reaches 69° and falls to 46°. The record high is 84°, in 1924; the record low 25°, in 2019. The most rain on this date, 4.91 in, fell in 1961.
