4.91 inches of rain fell in two days, the most for this week of the year since records began in 1887. The next wettest, 3.98 inches, fell in 1934.
Tierra Grande’s center stands about 60 ft above sea level. Within three miles the land runs from 30 ft to 60 ft, a difference of 30 ft: nearly flat ground.
Under the town center the state geologic map shows Beaumont Formation, areas predominantly 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. Age: Pleistocene, less than 2.6 million years old. About 15 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 8 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 0.6 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 Tierra Grande reaches Corpus Christi Bay and the Gulf of America by way of West Oso Creek and Oso Creek: about 20 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tierra Grande; river miles along the main stem, rounded.
Tierra Grande has a humid subtropical climate. Summer afternoons average 95° in August; winter nights fall to about 48° in January. About 32 inches of rain fall in a normal year.
On November 14 Tierra Grande normally reaches 76° and falls to 57°. The record high is 91°, in 1989; the record low 33°, in 2018. The most rain on this date, 1.91 in, fell in 1943.
Normals 1991–2020 and records since 1887 from the Corpus Christi Area threaded record (Corpus Christi International Airport, 7 miles northeast). NOAA, through RCC-ACIS.
