Overview
Hurricane Harvey made landfall in Texas on August 25, 2017, as a Category 4 storm, then stalled over Houston for days, dumping record rainfall. #HurricaneHarvey documented the catastrophic flooding that displaced 30,000+ people and caused $125 billion in damage — the costliest natural disaster in US history after Katrina.
Significance
Harvey dropped 60+ inches of rain in some areas — the greatest rainfall ever recorded in the continental US from a single storm. Houston, already below sea level in places, saw one-third of the city underwater. Over 300,000 structures flooded, 500,000+ cars destroyed, and 89 people died. The storm exposed Houston’s inadequate drainage infrastructure and unchecked development.
Heroic Response
Social media documented neighbor-helping-neighbor rescues: the “Cajun Navy” volunteers in boats, civilians evacuating nursing homes, volunteers forming human chains to rescue stranded families. Jim “Mattress Mack” McIngvale opened his furniture stores as shelters. Houston Texans star JJ Watt raised $37 million in relief funds.
Climate Connection
Harvey’s unprecedented rainfall aligned with predictions that warming atmospheres hold more moisture, intensifying precipitation. The storm rapidly intensified from tropical storm to Category 4 in 40 hours — a pattern becoming more common. Scientists estimated climate change increased Harvey’s rainfall by 15-38%.
