21° on Nov. 16, 1940, the coldest reading for this week of the year since 1911. Next is 22° in 1969.
Omega’s center stands about 330 ft above sea level. Within three miles the land runs from 250 ft to 350 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Miccosukee Formation (clay, sand, gravel), from the Tertiary Neogene, 2.6 to 23 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, sand, gravel. Age: Tertiary Neogene, 2.6 to 23 million years old. About 17 mi of the line.
Dolostone, sand, clay. Age: Miocene, 5.3 to 23 million years old. About 4 mi of the line.
Sandstone, claystone. Age: Tertiary Neogene, 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.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Omega reaches the Gulf of America by way of Gum Creek, the Little River, the Withlacoochee and the Suwannee: about 260 river miles.
130 miles of the trip are on the Suwannee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Omega; river miles along the main stem, rounded.
Omega has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 37° in January. About 48 inches of rain fall in a normal year.
On November 14 Omega normally reaches 68° and falls to 45°. The record high is 84°, in 1931; the record low 22°, in 2019. The most rain on this date, 1.65 in, fell in 1940.
Normals 1991–2020 and records since 1911 at Tifton, 10 miles northeast. NOAA, through RCC-ACIS.
