Past Wet Octobers
The long term rainfall averages for October show October in the top third
wettest months of the year for South Central Texas. The long term averages for October
show the month the 3rd wettest for Del Rio (1906 to 2004);
the 3rd wettest for Austin Bergstrom(1942-2004); the
4th wettest for Austin Mabry(1856-2004); and the 4th
wettest for San Antonio(1871-2004).
During the flood and heavy rain event of October 1998, the heavy rains fell
east of Del Rio. In the past 45 years, October rains were rather extreme in
1960, 1969, 1981, 1994, 1998, 2002, and 2004. In October 1960, heavy rains
affected parts of South Central Texas, including the Austin Area. The
wettest October of Record at Austin Bergstrom was in October 1960, when 13.08
inches of rain was observed. In October 1969, Del Rio had its 2nd wettest
October of Record when 11.33 inches of rain was observed. Nearly a year later
on September 27, 1970 Del Rio had 5.21 inches of rain, in the
middle of the 1970-1971 Drought. In October 1981, first the remnants of Hurricane
Norma from the Pacific moved over the region aloft and caused a heavy rain
event. Late in October 1981, a slow moving cool front and nearly stalled
upper-level trough created another heavy rain event, with plenty of high level
moisture from the remnants of Hurricane Otis to the southwest over Western
Mexico. In October 1994, a heavy rain event with thunderstorms moved through the
Austin and San Antonio Areas on Friday Night October 7th, and in the early
morning of Saturday October 8, 1994. Another rain event affected the area about
a week later from the remnants of Hurricane Rosa that moved over the area aloft
and another heavy rain event formed, in association with a slow moving
upper-level trough from the west. The heaviest rains in this event fell over the
eastern part of South Central Texas, with even heavier rains over Southeast
Texas.
After plentiful rains in September 1998, from the effects of Tropical
Storm Frances, extreme floods in October 1998 came. This was the wettest
October and Month of Record at San Antonio with 18.07 inches; the 2nd wettest
October of Record at Austin Bergstrom with 12.73 inches . and 3rd wettest
October of Record at Austin Mabry, with 12.39 inches.

13.08 inches in October 1960; and for Del Rio October 1930, when 11.69 inches of
rain fell. In October 2005 on the 13th, Del Rio experienced the
4th wettest day of record, when 7.59 inches of rain fell. This was a
record daily amount for the 13th of October.
