3.85 inches of rain fell in two days, the most for this week of the year since records began in 1914. The next wettest, 2.51 inches, fell in 2023.
Elsa’s center stands about 70 ft above sea level. Within three miles the land runs from 60 ft to 80 ft, a difference of 20 ft: nearly flat ground.
Under the town center the state geologic map shows Dune sand sheet deposits, from the Holocene, less than 12,000 years old.
The section below crosses 6 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: Holocene, less than 12,000 years old. About 7 mi of the line.
Clay, silt. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.

Elsa has a humid subtropical climate. Summer afternoons average 97° in August; winter nights fall to about 50° in January. About 26 inches of rain fall in a normal year.
On November 14 Elsa normally reaches 80° and falls to 59°. The record high is 94°, in 1921; the record low 30°, in 2018. The most rain on this date, 1.28 in, fell in 2008.
