Apr 18, 2023 · The NWS Office of Climate, Water and Weather Services and the National Climatic Data Center compiled this Summary of U.S. Natural Hazard Statistics from Storm Data, a report comprising statistics from NWS forecast offices in the 50 states, Puerto Rico, Guam, and the Virgin Islands.
Sep 26, 2023 · Fluvial flooding can either be overbank flooding—when the water level rises over the edges of a river, stream, or lake—or flash flooding—where there is a high volume of water moving at a high velocity in an existing riverbed with little advance notice.

Flooding is the most frequent and costliest natural disaster in the United States, and its costs are projected to rise as the climate warms. Decades of measurements, computer models and basic physics all point to increasing precipitation and sea level rise. As the atmosphere warms, it holds about 7% more moisture for every degree Celsius that the t...
We estimated that the annual cost of flooding today is over US$32 billion nationwide, with an outsized burden on communities in Appalachia, the Gulf Coast and the Northwest. When we looked at demographics, we found that today’s flood risk is predominantly concentrated in white, impoverished communities. Many of these are in low-lying areas directly...
Another important contributor to flood risk is the growing population. As urban areas expand, people are building in riskier locations, including expanding into existing floodplains – areas that were already at risk of flooding, even in a stable climate. That’s making adapting to the rising climate risks even more difficult. Hurricane Harvey made t...
If these results seem alarming, consider that these are conservative estimates. We used a middle-of-the-road trajectory for atmospheric greenhouse gas concentrations, one in which global carbon emissions peak in the 2040sand then fall. Importantly, much of this impact over the next three decades is already locked into the climate system. While cutt...
- Flooding Facts. What is a flood? A flood is the accumulation of water over normally dry land. It’s caused by the overflow of inland waters (like rivers and streams) or tidal waters, or by an unusual accumulation of water from sources such as heavy rains or dam or levee breaches.
- Flooding Causes. Many factors can go into the making of a flood. There are weather events (heavy or prolonged rains, storm surge, sudden snowmelt), and then there are the human-driven elements, including how we manage our waterways (via dams, levees, and reservoirs) and the alterations we make to land.
- Flood Consequences. When flooding inundates a home or community, it upends lives and introduces a litany of potential short- and long-term consequences.
- Flood Preparation. Advance preparation for a flood can save your property or even your life. (See FEMA.gov for a comprehensive flood preparation list.) To stay safe, take these precautions
