3.14 inches of rain fell in two days, the most for this week of the year since records began in 1896. The next wettest, 2.23 inches, fell in 1965.
West Valley’s center stands about 1,570 ft above sea level. Within three miles the land runs from 1,390 ft to 2,120 ft, a difference of 730 ft: hilly country. The highest named summit within 15 miles is McCarty Hill, about 2,410 ft, 11 miles south-southwest.
Under the town center the state geologic map shows Machias Formation (shale, siltstone, sandstone), from the Late Devonian, 359 to 384 million years old.

A raindrop that lands in West Valley reaches Lake Erie by way of Indian Creek, Buttermilk Creek and Cattaraugus Creek: about 45 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.

West Valley has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 13° in January. A normal year brings about 109 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 West Valley normally reaches 47° and falls to 29°. The record high is 66°, in 1989; the record low −4°, in 1905. The most rain on this date, 1.04 in, fell in 1972.
