Volume 15 Number 7 JULY 2002
The month of July will long be remembered for the torrential rains and flooding, which abruptly ended the extreme drought across much of the south, east and central portions of Texas. The rainfall total from July 1 -July 9 at the San Antonio International Airport was 16.92 inches, with many areas reporting in excess of 20 inches. Numerous locations in Texas, especially around San Antonio and New Braunfels, continue to purge the area of damage due to unfortunate flooding conditions. The governor estimates damage totals to be near 2 billion dollars.
Temperatures in many regions of Texas were below normal in the beginning and middle of the month as a result of prolonged days of showers and thunderstorms. These periods of cool, and wet weather resulted from two low-pressure systems that moved across the state. The city of San Antonio was constantly under attack by numerous waves of precipitation. Also, many other areas in Texas received ample rainfall that greatly exceeded the average rainfall for the month.
Cities that exceeded their average normal monthly totals are as listed: Abilene- 8.04", Austin-5.32", College Station-5.66", Corpus Christi-3.51", Dallas/Fort Worth-3.07", Galveston-3.73", Houston-7.10", San Angelo-2.02", San Antonio-16.92", Victoria-5.48", Waco-2.39", and Wichita Falls-2.92". Texas assumed a pattern of predominately dry and very warm weather toward the end of the month, with record temperatures reported statewide, including Wink at 108 ° F on July 27th.
