8.00 inches of rain fell in two days, the most for this week of the year since records began in 1892. The next wettest, 6.05 inches, fell in 1916.
Astor’s center stands about 12 ft above sea level. Within three miles the land runs from 0 ft to 80 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Undifferentiated sediments (sand, clay), from the Pleistocene to Holocene, 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.
Sand. Age: Holocene, less than 12,000 years old. About 6 mi of the line.
Sand. Age: Late Pliocene, 2.6 to 3.6 million years old. About 4 mi of the line.
Sand, clay. Age: Pleistocene to Holocene, less than 2.6 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.

A raindrop that lands in Astor reaches the St. Johns River and the Atlantic Ocean by way of Blue Creek and Trout Creek: about 130 river miles.
Lake on the way: George, Lake.
100 miles of the trip are on Trout Creek.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Astor; river miles along the main stem, rounded.
Astor has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 44° in January. About 56 inches of rain fall in a normal year.
On November 14 Astor normally reaches 76° and falls to 54°. The record high is 87°, in 2018; the record low 29°, in 1906. The most rain on this date, 2.40 in, fell in 1941.
Normals 1991–2020 and records since 1892 at Deland 1 SSE, 17 miles southeast. NOAA, through RCC-ACIS.
