Understanding Flood Warnings: Your Guide To Safety (NWS)

Different Types of Flood Warnings & Advisories Issued by the NWS

The NWS utilizes a system of warnings and advisories to communicate the potential for and occurrence of flooding. Understanding the differences between these alerts is vital for taking appropriate action. Here's a breakdown:

Flood Warning: This is the most serious alert. A Flood Warning means that flooding is occurring or is imminent. You should take immediate action to protect yourself and your property. Key phrases to watch for include: "Flooding is occurring," "Flooding is expected," "Immediate danger." These warnings are often geographically specific, targeting a particular county, river basin, or other defined area.
Flood Watch: A Flood Watch indicates that conditions are favorable for flooding. Flooding is possible, but not necessarily imminent. This is your time to prepare. Key phrases include: "Be prepared for flooding," "Conditions are favorable for flooding," "Potential for flooding." This allows you time to prepare your flood preparedness plan and review your evacuation routes.
Flood Advisory: A Flood Advisory signifies that flooding is possible in your area. While the threat is less severe than a watch or warning, you should still be aware of the potential for flooding and monitor conditions closely. Key phrases include: "Flooding is possible," "Minor flooding is expected," "Be aware of the potential for flooding."

Remember that all NWS flood warnings, watches, and advisories are location-specific. Pay close attention to the geographical area mentioned in the alert to determine if you are at risk.

Understanding the Severity of Flood Warnings

The NWS communicates the severity of flood warnings through descriptive language and, in some cases, color-coded systems. The potential impact can range from a minor inconvenience to a life-threatening danger.

Minor Flooding: May cause some inconvenience, such as road closures and ponding of water in low-lying areas.
Moderate Flooding: Can cause significant disruption, including damage to property, road closures, and potential evacuations.
Major Flooding: Poses a serious threat to life and property. Extensive damage is likely, and widespread evacuations may be necessary.
Catastrophic Flooding: This represents the most extreme level of flooding, resulting in widespread devastation and potentially numerous casualties.

Understanding the potential impact associated with each level of severity allows you to take appropriate precautions.

Preparing for and Responding to Flood Warnings

Effective preparation and response are essential for mitigating the risks associated with flooding.

Pre-Flood Preparation

Proactive measures before a flood warning is issued significantly improve your chances of safety and minimize potential damage.

Create a family communication plan: Establish a meeting point and contact information for all family members in case of separation.
Develop an evacuation plan and identify safe routes: Know your evacuation routes and have a backup plan in place.
Secure important documents and valuables: Store essential documents in waterproof containers and move valuables to higher ground.
Assemble an emergency kit: This kit should include water, non-perishable food, a first-aid kit, medications, flashlights, batteries, and any other essential supplies. This constitutes your flood preparedness plan.

During a Flood Warning

When a flood warning is issued, immediate action is crucial.

Evacuate immediately if instructed: Obey evacuation orders from local authorities. Your life is more important than your property.
Never drive through flooded areas: Floodwaters can be deceptively deep and swift, making them extremely dangerous.
Stay away from downed power lines: Downed power lines pose a severe electrical hazard.
Monitor the NWS for updates: Continuously monitor weather reports for updates and instructions.

Post-Flood Actions

Even after the floodwaters recede, there are important steps to take.

Check for structural damage to your home: Assess your home for damage and contact professionals as needed.
Avoid floodwaters: Floodwaters can be contaminated with sewage and other hazardous materials.
Contact your insurance company: Report the flood damage to your insurance company as soon as possible.
Report damage to local authorities: Help your community by reporting damage to local officials.
