Are flood watches different from flood warnings?

Understanding Flood Watches and Warnings

Flood watches are typically issued 12 to 24 hours in advance of potential flooding, giving residents time to prepare and take necessary precautions. These watches are usually issued when heavy rainfall, storm surges, or other factors are creating conditions that could lead to flooding. In contrast, flood warnings are issued with much shorter notice, often just a few hours or even minutes, when flooding is imminent or already occurring.

Recognizing the Difference: When to Act

When a flood watch is issued, it’s essential to monitor local news and weather reports for updates and to be prepared to take action. This might involve moving valuables to higher ground, securing loose outdoor items that could become projectiles in strong winds, and having a plan in place for potential evacuation. On the other hand, when a flood warning is issued, it’s critical to take immediate action. This could mean evacuating the area, moving to higher ground, or seeking shelter in a sturdy building. In the event of a flash flood warning, which is a type of flood warning issued for rapid-onset flooding, it’s essential to act quickly and seek higher ground immediately.

Staying Safe During Floods: Vehicle and Swift Water Risks

When navigating flooded areas, it’s crucial to remember that water can be deceptively deep and fast-moving. Never attempt to drive through flooded roads or areas, as even a few inches of water can stall a vehicle. In fact, the National Weather Service estimates that between 2006 and 2015, there were over 300 deaths in the United States due to flooding, with many of those victims trapped in vehicles. When approaching flooded areas, look for signs of swift water, such as foamy or discolored water, and be aware of the potential for strong currents and undertows. If you’re caught in a flood and need to escape, seek high ground immediately and avoid walking or driving through floodwaters.
