5.72 inches of rain fell in two days, the most for this week of the year since records began in 1871. The next wettest, 5.59 inches, fell in 1914.
Satsuma’s center stands about 30 ft above sea level. Within three miles the land runs from 0 ft to 90 ft, a difference of 90 ft: gently rolling country. The highest named summit within 15 miles is Stony Hill, about 250 ft, 11 miles east-southeast.
Under the town center the state geologic map shows Alluvial, coastal and low terrace deposits (sand), from the Holocene, less than 12,000 years old.
The section below crosses 3 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. Age: Holocene, less than 12,000 years old. About 12 mi of the line.
Sand. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 4 mi of the line.
Sand, clay. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Satsuma reaches Mobile Bay and the Gulf of America by way of Steele Creek, Gunnison Creek, the Bayou Sara, the Big Bayou Canot and the Mobile: about 18 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Satsuma; river miles along the main stem, rounded.
Satsuma has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 41° in January. About 67 inches of rain fall in a normal year.
On November 14 Satsuma normally reaches 70° and falls to 48°. The record high is 82°, in 2008; the record low 28°, in 1969. The most rain on this date, 1.55 in, fell in 1929.
