Flooding in the US today looks very different than it did just a decade ago, when most events were largely confined to coastal areas. Now, inland flooding is rapidly emerging as a major and growing threat, affecting communities far beyond the shoreline.
Recent events highlight the urgency of addressing this issue, as climate change intensifies weather patterns and exacerbates flood risks in areas previously considered safe.
Recent Inland Flooding Events in the US
- Southern U.S. Storms - In early April 2025, severe storms swept through southern states like Arkansas, Kentucky, and Tennessee, resulting in at least 24 deaths, primarily due to flooding. A study by the World Weather Attribution group found that climate change increased the rainfall intensity by 9% and made such storms 40% more likely than in pre-industrial times.
- Connecticut River Flooding - Earlier this month, the Connecticut River experienced minor flooding due to several days of heavy rainfall. River levels in Hartford and Middlesex counties peaked at or slightly above flood stage, leading to closures like the Rocky Hill ferry and prompting flood warnings from the National Weather Service. Flooding in the US today is attributed not only to local rainfall but also to heavy precipitation in upstream regions, such as Vermont and Massachusetts in this case.
- Laredo, Texas Flooding - On May 8, 2025, heavy rainfall led to significant flooding in Laredo, Texas, submerging lanes on State Highway 359 and causing multiple traffic accidents. The area was under a severe thunderstorm warning, highlighting the rapid onset and dangers of flash flooding.
How Flooding in the US Today Increases With Climate Change
As climate change continues to alter precipitation patterns and increase the frequency of extreme weather events, regions that were once considered low-risk are now facing more frequent and severe flooding. These are not isolated events - they are part of a broader, ongoing pattern that signals a significant shift in flood risk across inland areas of the United States.
- Inland flooding is increasingly linked to climate change - Rising global temperatures lead to more evaporation, resulting in heavier and more frequent rainfall events.
- Scientific evidence supports the connection - A World Weather Attribution study found that human-induced climate change significantly increased the severity and likelihood of the April 2025 storms in the southern U.S.
- Long-term data shows a clear trend - Since 1988, shifts in precipitation patterns have accounted for over one-third (37%) of inland flood damage in the U.S.
Preparing for a Future With Increased Inland Flooding
While coastal regions often receive attention for flood preparedness, inland areas are increasingly vulnerable. For instance, Houston, Texas, is sinking faster than any other major U.S. city due to extensive groundwater and oil extraction, exacerbating flood risks.
Similarly, cities like Chicago and Denver are experiencing land subsidence, which can strain infrastructure and worsen flooding . Additionally, areas with poor drainage systems or those near rivers and lakes are susceptible to flooding from intense rainstorms, even if they are far from the coast.
Addressing the growing threat of inland flooding in the US today requires a multifaceted approach:
- Infrastructure Improvements - Upgrading drainage systems, reinforcing levees, and implementing sustainable urban planning can mitigate flood impacts.
- Policy and Planning - Incorporating climate projections into land-use planning and building codes ensures that new developments are resilient to future flood risks.
- Community Engagement - Educating communities about flood risks and preparedness measures can enhance resilience and response during flood events.
- Investments in Flood Products - Flood barriers, sump pumps, and other flood protection products can significantly reduce or completely eliminate the risk of flood damage to properties.
When it comes to flooding in the US today, as climate change continues to alter weather patterns, inland flooding will become an increasingly pressing issue. Proactive measures, informed by scientific research and community involvement, are essential to safeguard lives and property across the nation.
