2 Jun
Summary
- Tropical Storm Allison dropped over three feet of rain, causing immense damage.
- Twenty-three people died in Texas, with 30,000 needing emergency shelter.
- The storm caused $5 billion in damages, destroying over 70,000 homes.

Tropical Storm Allison, which occurred 25 years ago, serves as a stark reminder that non-hurricane-strength storms can inflict widespread destruction. The storm, forming on June 4, 2001, and making landfall the next day, inundated parts of Houston with over three feet of rain, causing deadly flooding and billions in damages.
In Texas, 23 lives were lost due to Allison. The storm caused an estimated $5 billion in damages, impacting more than 70,000 homes in the Houston area. The Harris County Flood Control District has since invested at least $1.5 billion in flood control projects to better prepare the region for future events.
