What is a Flood Watch?
A flood watch is issued when weather conditions could lead to flooding in the next 12 to 48 hours. It means that heavy rain, melting snow, or other water events might cause rivers, streams, or low-lying areas to flood. When you hear a flood watch, you should stay alert, check weather updates regularly, and prepare an emergency kit with important documents, supplies, and a plan for where to go if you need to evacuate.
What is a Flood Warning?
A flood warning is issued when flooding is actually happening or will happen very soon, usually within minutes to a few hours. This is a serious alert that means water is already rising dangerously or will do so imminently in your area. When a flood warning is issued, you should leave low-lying areas immediately, move to higher ground, and follow instructions from local emergency officials.
Key Differences
The main difference is urgency and timing. A watch means be ready and stay informed. A warning means act now and leave if instructed. Watches give you hours or more to prepare, while warnings require immediate action. Think of it like this: a watch is a yellow light telling you to get ready, and a warning is a red light telling you to go or get out of the way.
What You Should Do
During a flood watch, gather supplies, know your evacuation route, charge your devices, and keep your family informed. During a flood warning, leave immediately if told to do so, do not drive through flooded roads, and move to higher ground. Never try to cross a flooded road in a car, as fast-moving water can sweep vehicles away.
