3.02 inches of rain fell in two days, the most for this week of the year since records began in 1923. The next wettest, 3.00 inches, fell in 2014.
Gu-Win’s center stands about 570 ft above sea level. Within three miles the land runs from 440 ft to 730 ft, a difference of 290 ft: rolling country. The highest named summit within 15 miles is Bee Mountain, about 880 ft, 11 miles north.
Under the town center the state geologic map shows Tuscaloosa Group; Coker Formation (sand, clay), from the Cretaceous, 66 to 145 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 45×. 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: Cretaceous, 66 to 145 million years old. About 15 mi of the line.
Sand, clay. Age: Cretaceous, 66 to 145 million years old. About 4 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 2 mi of the line.

A raindrop that lands in Gu-Win reaches Mobile Bay and the Gulf of America by way of Luxapallila Creek, the Tombigbee and the Mobile: about 400 river miles.
290 miles of the trip are on the Tombigbee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Gu-Win; river miles along the main stem, rounded.
Gu-Win has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 30° in January. About 64 inches of rain fall in a normal year.
On November 14 Gu-Win normally reaches 64° and falls to 39°. The record high is 80°, in 1985; the record low 20°, in 2019. The most rain on this date, 2.95 in, fell in 2024.
Normals 1991–2020 and records since 1923 at Winfield 2 SW, 4 miles south-southeast. NOAA, through RCC-ACIS.
