6.35 inches of rain fell in two days, the most for this week of the year since records began in 1902. The next wettest, 3.35 inches, fell in 2003.
Edna’s center stands about 70 ft above sea level. Within three miles the land runs from 30 ft to 80 ft, a difference of 50 ft: nearly flat ground.
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 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.
Sand. Age: Pleistocene, less than 2.6 million years old. About 9 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 6 mi of the line.
Clay, silt. Age: Pleistocene, less than 2.6 million years old. About 6 mi of the line.
Silt, sand, clay. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.

A raindrop that lands in Edna reaches the Gulf of America by way of Dry Creek and the Lavaca: about 25 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Edna; river miles along the main stem, rounded.
Edna has a humid subtropical climate. Summer afternoons average 95° in July; winter nights fall to about 43° in January. About 40 inches of rain fall in a normal year.
On November 14 Edna normally reaches 74° and falls to 52°. The record high is 93°, in 1921; the record low 28°, in 2018. The most rain on this date, 2.09 in, fell in 1998.
