Project Description

During the weekend of 17-18 October 1998, heavy rains fell over south and southeast Texas. Low level moisture was transported into southeast Texas from the Gulf of mexico while Hurricane Madeline off the Pacific coast of Mexico provided mid-level moisture into southern Texas. 20 to 30 inches of rain fell locally near San Antonio, with surrounding areas receiving 10 to 20 inches of precipitation. This heavy rainfall resulted in flash flooding from San Antonio to Austin, followed by record breaking river flooding along several southern Texas rivers in the following days. 31 people drowned during the flooding.

Objectives
