Flooding is a temporary overflow of water onto land that is normally dry. Floods can result from rain, snow, coastal storms, storm surges, overflows of rivers, and dam failure. Floods can be dangerous. People die by drowning when they don’t evacuate before floodwaters come or when they enter floodwaters. Floods can damage buildings and roads, cause power outages, and create landslides.
Floodwaters carry waste and pollute drinking water. Flooding can develop slowly or quickly. Flash floods can be sudden and violent. Climate change increases our risk of many types of flooding. But we can take action to prepare. Prepare now to protect yourself and your loved ones.
