Inland flooding is when the volume of water on land overcomes the capacity of natural and built drainage systems to carry it away. It can result from landfalling coastal storms, heavy precipitation events, snowmelt, dam failures and more. Learn how climate change is increasing inland flooding risks and what communities can do to adapt.

- Inland Floods. Inland flooding is the technical name for ordinary flooding that occurs in inland areas, hundreds of miles from the coast. Flash flooding, river flooding, and pretty much every type of flooding except coastal can be categorized as an inland flood.
- Flash Floods. Flash floods are caused by heavy rain or the sudden release of water over a short period of time. The name "flash" refers to their fast occurrence (typically within minutes to hours after the heavy rain event) and also to their raging torrents of water that move with great speed.
- River Floods. River flooding occurs when water levels in rivers, lakes, and streams rise and overflow onto the surrounding banks, shores, and neighboring land.
- Coastal Floods. Coastal flooding is the inundation of land areas along the coast by seawater. Common causes of coastal flooding include: High tide; Tsunamis (large ocean waves generated by underwater earthquakes that move inland);
Aug 3, 2022 · This is how a flash flood happens, and it can be extremely dangerous. Moving water can tear homes from foundations, destroy roads, fill underground subway stations and wash away cars.
May 7, 2024 · What is inland flooding? Inland floods occur when rivers overflow their banks (fluvial flooding) or when precipitation exceeds local capacity to absorb water (pluvial flooding) in soils or urban...

A river flood occurs when water levels rise over the top of river banks due to excessive rain from tropical systems making landfall, persistent thunderstorms over the same area for extended periods of time, combined rainfall and snowmelt, or an ice jam. A coastal flood, or the inundation of land areas along the coast, is caused by higher than avera...
Storm surge is an abnormal rise in water level in coastal areas, over and above the regular astronomical tide, caused by forces generated from a severe storm's wind, waves, and low atmospheric pressure. Storm surge is extremely dangerous, because it is capable of flooding large coastal areas. Extreme flooding can occur in coastal areas particularly...
Areas damaged by wildfires are known as burn scars and are particularly susceptible to flash floods and debris flows during rainstorms. Rainfall that is normally absorbed by vegetation can run off almost instantly, causing creeks and drainage areas to flood much earlier and with higher magnitude than normal.
What we do: NSSL supplied real-time close-up radar mobile radar data during rain events in southern California where the local NWS radar beam is blocked by the terrain. The effort was part of the NOAA/USGS demonstration flash flood and debris flow early warning system to help forecasters improve flash flood and debris flow warnings in areas damaged...
Learn about different types of floods, such as river, coastal, storm surge, inland, and flash floods, and how they are caused and monitored by NOAA. Find out how NSSL provides radar data and forecasts for flood events in various regions of the US.
Jun 25, 2012 · Inland flooding is a serious threat caused by heavy rainfall from hurricanes over land, accounting for more than 25 percent of U.S. hurricane deaths. NOAA's River Forecast Centers monitor water levels and issue warnings to alert communities of potential floods.
Nov 3, 2023 · A flood, put simply, is the accumulation of water over normally dry land. It’s typically caused by the overflow of coastal or inland waters (like rivers and streams) or by an...
