11.00 inches of rain fell in two days, the most for this week of the year since records began in 1895. The next wettest, 6.77 inches, fell in 1918.
Carlyss’s center stands about 12 ft above sea level. Within three miles the land runs from 0 ft to 50 ft, a difference of 50 ft: nearly flat ground.
Under the town center the state geologic map shows Prairie Terraces (clay, silt, sand), from the Pleistocene, less than 2.6 million 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 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, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 15 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Clay, silt. Age: Holocene, less than 12,000 years old. About 2 mi of the line.

A raindrop that lands in Carlyss reaches the Gulf of America by way of the Calcasieu: about 30 river miles.
Lake on the way: Mud Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Carlyss; river miles along the main stem, rounded.
Carlyss has a humid subtropical climate. Summer afternoons average 93° in August; winter nights fall to about 43° in January. About 60 inches of rain fall in a normal year.
On November 14 Carlyss normally reaches 72° and falls to 51°. The record high is 87°, in 1917; the record low 29°, in 1940. The most rain on this date, 5.40 in, fell in 1918.
Normals 1991–2020 and records since 1895 from the Lake Charles Area threaded record (Lake Charles Regional Airport, 9 miles east-southeast). NOAA, through RCC-ACIS.
