The Lauderdale plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
3.88 inches of rain fell in two days, the most for this week of the year since records began in 1961. The next wettest, 3.40 inches, fell in 2014.
Lauderdale’s center stands about 230 ft above sea level. Within three miles the land runs from 200 ft to 370 ft, a difference of 170 ft: gently rolling country. The highest named summit within 15 miles is Thornton Hill, about 400 ft, 15 miles southeast.
Under the town center the state geologic map shows Wilcox formation (sand, clay), from the Eocene, 34 to 56 million years old.
The section below crosses 4 rock units mapped at the surface.

A raindrop that lands in Lauderdale reaches Mobile Bay and the Gulf of America by way of the Sucarnoochee, the Tombigbee and the Mobile: about 280 river miles.
160 miles of the trip are on the Tombigbee.

Lauderdale has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 36° in January. About 55 inches of rain fall in a normal year.
On November 14 Lauderdale normally reaches 68° and falls to 43°. The record high is 83°, in 2011; the record low 23°, in 1969. The most rain on this date, 1.14 in, fell in 1993.
